Business process automation cost is the figure every UK operations director asks for first, and the one almost every supplier answers with a range so wide it tells you nothing. Ask three firms what it takes to automate your purchase invoices and you will be quoted £8,000, £30,000 and “let’s scope it” — all three defensible, none of them checkable. Meanwhile the finance director wants a single number to put next to a payback period, for a business with ninety staff, a tired line-of-business system and nobody spare to build anything.
This guide builds that number from the bottom up. Every rate below comes from a primary source published in August 2026: Microsoft’s own UK price list in pounds, the ITJobsWatch contract and permanent indices for the six months to 21 August 2026, the Office for National Statistics earnings survey, and each automation vendor’s public pricing page. Where a figure could not be verified, we say so instead of guessing. What follows is a full three-year model for one realistic ninety-person firm, a break-even test you can apply to any candidate process in about four minutes, and a conclusion that half of this industry would rather you did not reach.
If you want the return side of the equation rather than the pricing side, our automation ROI calculator covers the benefit modelling, and our comparison of RPA, workflow tooling and AI agents covers which technology suits which job. This article is narrower and harder: what the invoices actually say, and which processes are worth putting on one. The full picture of what we do in this space sits on our business process automation service page.

What Business Process Automation Cost Actually Covers
Ask a supplier to price business process automation and you will get an answer to whichever question they find most flattering. There are three separate numbers hiding behind the phrase, and confusing them is the single most common reason automation programmes disappoint the people who funded them.
The three business process automation cost numbers behind one question
The first business process automation cost is the build fee: what somebody charges to design, configure and test the automations. The second is the platform run rate: what Microsoft, or Zapier, or anyone else bills you every month for the licences that keep those automations legal and running. The third is the change budget: what it costs to keep the automations working when the supplier changes their invoice layout, the finance system gets patched, or the person who owned the process leaves.
Most quotes answer only the first. Most disappointment arrives from the second and third. A supplier can win the work on a genuinely honest £18,450 build fee and still leave you with a business process automation cost that never stops.
Why the run rate outlives the project
A build is a one-off event. The business process automation cost run rate compounds. In the three-year model below, the build is 56.7% of the total and the other 43.3% is licences and change — money that appears after everybody has stopped paying attention. Any business process automation cost estimate that stops at the build fee is describing less than three-fifths of what you will spend.
The honest business process automation cost framing
There is no generic business process automation cost. There is only the business process automation cost of a specific process, at a specific volume, with a specific licensing decision applied. Change the volume and every figure below moves. The same is true of the technology: a cloud workflow and robotic process automation driving a screen carry very different licence lines for identical business logic. What transfers between businesses is not the total — it is the shape of the business process automation cost, and the arithmetic that tells you when to walk away.
The Ninety-Person Firm Behind Every Business Process Automation Cost Figure
To keep the arithmetic checkable, everything below prices one fictional but entirely ordinary business: a wholesale distributor in Leeds with ninety employees, six in finance, five in sales administration and four in operations support.
Why this size of firm is the right test case
Of the 5.7 million UK private sector businesses recorded at the start of 2025, 5.64 million had fewer than fifty employees and only 38,435 sat in the 50-249 band. Enterprise automation case studies price programmes for organisations that barely exist in this country. A ninety-person distributor is far closer to the national norm, and it is exactly the size at which the business process automation cost arithmetic gets uncomfortable — big enough to have real transaction volume, too small to spread a platform bill across thousands of seats.
The six candidate processes
The operations director produced this list, which is the list almost every distributor produces. Volumes are monthly, and “minutes each” is the observed hands-on time, measured with a stopwatch rather than estimated in a workshop.
| Process | Items/month | Minutes each | Gross hours/month | Straight-through rate | Hours saved/month |
|---|---|---|---|---|---|
| Purchase invoice processing | 340 | 6.5 | 36.83 | 82% | 30.20 |
| Sales order entry | 610 | 4.0 | 40.67 | 74% | 30.09 |
| Customer onboarding and credit checks | 45 | 22.0 | 16.50 | 60% | 9.90 |
| Supplier statement downloads | 120 | 7.0 | 14.00 | 90% | 12.60 |
| Month-end reporting pack | 1 | 660.0 | 11.00 | 70% | 7.70 |
| Starter and leaver provisioning | 9 | 95.0 | 14.25 | 80% | 11.40 |
| Total | 1,125 | — | 133.25 | — | 101.90 |
What 101.90 hours a month is actually worth
That is 1,222.76 hours a year. Before any business process automation cost is incurred, be clear what that buys back: at 227 working days and 7.5 hours a day, one full-time administrator supplies 1,702.5 hours, so the entire six-process programme recovers 0.7182 of one person. Not a department. Not a headcount reduction you can put in a board pack without a conversation.
The value of an hour, stated properly
A finance or sales administrator on £28,500 costs more than £28,500. Employer National Insurance at 15% on earnings above the £5,000 secondary threshold adds £3,525, and a 3% pension contribution on full salary adds £855, giving a loaded cost of £32,880. Divided by 1,702.5 hours that is £19.3128 an hour, and every benefit figure in this article uses it. The 1,222.76 hours are therefore worth £23,614.89 a year.
UK Day Rates That Set Your Business Process Automation Cost
Labour is the largest single component. These are not estimates — they are the published medians from ITJobsWatch for the six months to 21 August 2026.
What the public index actually says
| Role | Median | 25th | 75th | 90th | Sample | Outside London |
|---|---|---|---|---|---|---|
| Power Platform, contract | £500/day | £413 | £588 | £659 | 1,647 rates | £450 |
| Power Automate, contract | £488/day | £413 | £545 | £600 | 376 rates | £450 |
| Business analyst, contract | £500/day | £425 | £600 | £675 | 1,376 rates | £475 |
| Power Automate, permanent | £55,000 | £45,000 | £75,000 | £90,000 | 563 salaries | £53,171 |
| Robotic process automation, permanent | £66,250 | £52,500 | £87,000 | — | 12 salaries | £82,000 |
Two cautions on that last row. Twelve salaries is far too thin a sample to plan a budget around, and the specialist tooling market is now small enough that only 25 permanent UK vacancies cited it in six months — 0.023% of the total. Power Platform, by contrast, appeared in 2,507 contract vacancies, 4.68% of the entire UK contract market and 42nd in the national ranking. That gap matters when you are deciding which skill your business process automation cost is going to depend on for the next five years.
The in-house rate nobody calculates
A permanent developer at the £55,000 median costs £55,000 plus £7,500 employer National Insurance plus £1,650 of pension: £64,150. Across 227 working days that is £282.60 a day — 37.2% below the outside-London contract median. In-house is genuinely the cheapest labour, provided the person already exists. Recruiting one adds roughly a fifth of salary in agency fees and three months before they are productive, which is why the cheapest rate on the table is so rarely the cheapest option in practice.
What a partner day actually costs
Partner rates are not in any public index, so we derive rather than invent one: take the published 75th-percentile Power Platform contract rate of £588 and add a stated 20% for delivery management, quality assurance and account overhead. That gives a blended £705.60 a day, which is the business process automation cost figure used for the partner routes below. It is an assumption, clearly labelled, built on a published number.
Microsoft Licensing and Business Process Automation Cost
For a firm already on Microsoft 365, the platform decision is usually Power Platform, so its price list deserves reading properly rather than skimming. Every figure below is the published UK annual-commitment price, excluding VAT, as at 21 August 2026.
The published price list
| Licence | Unit | Per month | Per year | What it buys |
|---|---|---|---|---|
| Power Automate Premium | per user | £11.50 | £138.00 | Premium connectors, one named person |
| Power Automate Process | per bot | £115.30 | £1,383.60 | One flow, unlimited users |
| Power Automate Hosted Process | per bot | £165.30 | £1,983.60 | The above plus a Microsoft-run Windows machine |
| Power Apps Premium | per user | £15.40 | £184.80 | Apps plus flows within the app |
| Dataverse database capacity | per GB | £30.80 | £369.60 | Storage above the included allowance |
| Copilot Studio | per tenant | £153.80 | £1,845.60 | 25,000 credits a month |
| Process Mining add-on | per tenant | £3,844.80 | £46,137.60 | Discovery tooling, Premium plan only |
The 10.03-user crossover that halves a business process automation cost
Here is the single most useful piece of licensing arithmetic in the whole platform. A Process licence at £115.30 divided by a Premium licence at £11.50 is 10.0261. Below ten named people who need to trigger a flow, per-user licensing is cheaper. Above ten, the per-flow licence is. At exactly ten users the two are 30 pence apart — £115.00 against £115.30 — which is as close to a clean decision rule as enterprise licensing ever gets.
Get this backwards and the business process automation cost roughly doubles for no benefit at all. In the worked model below, two flows had been quoted with Process licences by default; four and seven people respectively actually needed to trigger them, and switching both to Premium saved £1,249.20 a year.
What “we already have Microsoft 365” really buys
It buys the seeded entitlement, and the seeded entitlement is narrower than most people assume. It covers standard connectors only, and it allows 6,000 platform requests per user per 24 hours against the 40,000 a Premium licence carries. Anything touching a SQL database, an on-premises file share, a third-party finance system or a raw HTTP endpoint needs a premium connector, and a premium connector needs a paid licence. “It’s included” is true right up to the point where the automation does anything useful.
The Request Limits That Quietly Set Business Process Automation Cost
Licence prices are published. Request entitlements are documented but rarely modelled, and they are what decides whether your business process automation cost stays flat or steps up a tier in month seven.
Entitlements and the real business process automation cost per request
| Licence | Requests per 24 hours | Scope | Monthly price | Cost per 1,000 requests |
|---|---|---|---|---|
| Microsoft 365 seeded | 6,000 | per user | Bundled | — |
| Power Automate Premium | 40,000 | per user | £11.50 | £0.009457 |
| Power Automate Process | 250,000 | per flow | £115.30 | £0.015171 |
| Power Automate Hosted Process | 250,000 | per flow | £165.30 | £0.021750 |
| Capacity add-on pack | +50,000 | per pack | Not published | — |
Why the per-flow licence costs more per request
Run the division and the Process licence is 60.42% dearer per request than Premium, and Hosted Process is 2.30 times the Premium unit price. You are not buying volume when you buy a Process licence; you are buying the removal of the per-user cap and a guaranteed allocation that no individual can exhaust. That is worth paying for above ten users and worth avoiding below ten — which is the crossover again, arriving from a different direction.
Two limits that catch people out
The five-minute ceiling is 100,000 requests regardless of licence, so a flow that fans out across a large batch can be throttled while sitting comfortably inside its daily allowance. And desktop flow executions do not consume platform requests at all, which is the one piece of good news in this section: the machine-driven work that feels most expensive is metered by licence, not by volume.
Process Mining: The Business Process Automation Cost Trap
Every discovery conversation eventually reaches the suggestion that you buy the mining tool first and find out where the waste is. Price it before you agree.
£46,137.60 a year to find what your team already knows
The Process Mining add-on is £3,844.80 per tenant per month, or £46,137.60 a year. Divide that by the £115.30 Process licence and it is 33.35 flow licences — the discovery tool costs more than automating thirty-three processes outright. For the ninety-person distributor in this model, with six candidate processes and a total programme build of £18,450, the mining tool alone would be 2.5 times the entire build fee.
What to do instead at this size
Sit with the two people who do the work, time twenty real transactions with a stopwatch, and write down where each one stalls. It takes two days, it costs under £1,000 at contractor rates, and it produces the same six-line list. Mining earns its business process automation cost when you have hundreds of process variants and no idea which ones exist; it is indefensible when you have six and everyone can name them. Our guide to running an automation discovery workshop covers the manual version in detail, and the trade-off is argued at length in our piece on process mining versus traditional mapping.
Business Process Automation Cost by Delivery Route
The six-process programme needs 114 days of effort: 14 days of discovery and analysis, 72 days of build and configuration, 16 days of testing and user acceptance support, and 12 days of deployment, training and hypercare. The same 114 days priced four ways produces a spread most buyers would not believe.
| Route | Day rate | 114 days | Index | What you are also buying |
|---|---|---|---|---|
| In-house developer, fully loaded | £282.60 | £32,216.30 | 100 | Retained knowledge, single point of failure |
| Contractor, outside London | £450.00 | £51,300.00 | 159 | Speed, no cover when they leave |
| Contractor, London median | £500.00 | £57,000.00 | 177 | Deeper market, same exposure |
| Partner, time and materials | £705.60 | £80,438.40 | 250 | Cover, review, escalation, method |
| Partner, fixed price (+18% risk) | — | £94,917.31 | 295 | Transfer of overrun risk |
What the 2.95x spread is actually buying
The gap between the cheapest and dearest route is £62,701.01 on identical scope. That is not a scandal — it is a genuine choice about who absorbs risk. The in-house route assumes you have the person, that they stay, and that nobody else needs them for 114 days. The fixed price route assumes none of that and charges an 18% premium for saying so. Most SMEs should price at least two routes before accepting either, and should be extremely suspicious of a business process automation cost quoted without the day count that produced it.
The business process automation cost number to demand from every supplier
Ask for days and a rate, not a total. A £38,000 quote is unanswerable; “84 days at £450” is a conversation. If a supplier will not decompose their business process automation cost into effort and rate, they are protecting either a margin or an estimate they cannot defend, and both are your problem later.
The Break-Even Test Every Business Process Automation Cost Should Pass
This is the part worth keeping. It takes four minutes per process and it disqualifies more candidates than any workshop.
The formula, stated in full
Amortise the build over three years, add a change budget of 15% of build effort per year, add the licence, and compare the annual total against the value of the hours the automation actually removes.
Annual cost = (build days × £450 ÷ 3) + (build days × £450 × 0.15) + annual licence. At £450 a day that collapses to build days × £217.50 + licence. Value per item = minutes × straight-through rate × £19.3128 ÷ 60. Break-even monthly volume = annual cost ÷ (12 × value per item).
The business process automation cost grid
This assumes an 80% straight-through rate and four Premium licences at £552 a year — the commonest small-flow shape. Read down for build effort, across for how long the task takes a human.
| Build days | Annual cost | 3-minute task | 6-minute task | 12-minute task | 25-minute task |
|---|---|---|---|---|---|
| 6 days | £1,857.00 | 200/month | 100/month | 50/month | 24/month |
| 12 days | £3,162.00 | 341/month | 171/month | 85/month | 41/month |
| 20 days | £4,902.00 | 529/month | 264/month | 132/month | 63/month |
| 30 days | £7,077.00 | 763/month | 382/month | 191/month | 92/month |
How to read the business process automation cost grid
A twelve-day automation of a six-minute task needs 171 items a month before the business process automation cost is recovered inside three years. If you are doing eighty a month, no amount of enthusiasm changes the answer. The grid also explains why “quick wins” are real: at six build days and a three-minute task, 200 items a month clears it, and a lot of admin work is genuinely that repetitive.
Which of the Six Passed the Business Process Automation Cost Test
Applying that formula to the six candidates, using each process’s own straight-through rate and its own licence, produces a result the operations director did not expect.
| Process | Build days | Licence/year | Annual cost | Break-even | Actual | Verdict |
|---|---|---|---|---|---|---|
| Purchase invoice processing | 16 | £552.00 | £4,032.00 | 196/month | 340 | 1.74x — build it |
| Starter and leaver provisioning | 6 | £414.00 | £1,719.00 | 6/month | 9 | 1.54x — build it |
| Sales order entry | 19 | £966.00 | £5,098.50 | 446/month | 610 | 1.37x — build it |
| Month-end reporting pack | 8 | £552.00 | £2,292.00 | 1.3/month | 1 | 0.78x — defer |
| Supplier statement downloads | 11 | £1,983.60 | £4,376.10 | 180/month | 120 | 0.67x — defer |
| Customer onboarding and credit checks | 12 | £1,478.40 | £4,088.40 | 80/month | 45 | 0.56x — defer |
Three business process automation cost failures, three different causes
The three that failed did so for three entirely unrelated reasons, and that is the useful part. Month-end fails because it happens once a month — the task is eleven hours long and still cannot clear an £2,292 annual cost. Supplier statements fail because desktop tooling drags a £1,983.60 licence behind them. Customer onboarding fails because forty-five items a month is simply not enough volume, no matter how tedious each one is.
Every failing business process automation cost has a cause you can name. If a supplier tells you a process is not worth automating, ask which of those three it is; if they cannot say, they have not done the arithmetic either.
Why the Longest Tasks Fail the Business Process Automation Cost Test
The instinct is always to automate whatever takes longest. It is almost always wrong, and the model shows exactly why.
Eleven hours, once
The month-end pack consumes eleven hours in one sitting, which makes it the most visible pain in the finance team’s calendar. But visibility is not volume. Twelve occurrences a year at 70% straight-through recovers 92.4 hours — £1,784.51 of value against a £2,292.00 annual cost. It fails by £507.49, and it would fail even if the build were free in year one, because the licence and change budget alone are £1,003.50.
Twenty-two minutes, forty-five times
Customer onboarding looks like the perfect candidate: heavy, manual, error-prone, universally hated. At 45 a month and a 60% straight-through rate it recovers 9.90 hours a month, worth £2,293.94 a year against £4,088.40. The Power Apps front end that makes it usable is exactly what makes it uneconomic — eight users at £184.80 is £1,478.40 before a single line is built.
The business process automation cost rule this produces
Rank candidates by hours recovered per build day, never by minutes per item. On that measure the six-day starter and leaver flow beats every other process in the list, and the twelve-day onboarding project comes last. Our note on choosing the first process to automate makes the same argument from the delivery side.
Desktop Automation and the Business Process Automation Cost Premium
Some processes cannot be done with an API because the system on the other end does not have one. That is where robotic process automation earns its keep, and where the business process automation cost steps up sharply.
The 48.6% break-even penalty
The supplier statement process needs a machine to log into six supplier portals and download PDFs. With four Premium licences at £552 a year its break-even volume would be 121 items a month. With the Hosted Process licence it genuinely requires, at £1,983.60, break-even rises to 180 a month — 48.6% higher for exactly the same automation. The extra £1,431.60 a year is the business process automation cost of the portal having no API, and it is the single clearest example of a business process automation cost that has nothing to do with your automation and everything to do with somebody else’s software.
Hosted, or your own machine?
The Hosted Process licence costs £50.00 a month more than the ordinary Process licence — a 43.37% uplift purely for Microsoft to run the Windows machine. That sounds like a lot until you price the alternative. A B2s v2 virtual machine running Windows in Azure’s UK South region is £0.0783 an hour, or £57.16 a month at list, before disks, patching or anyone’s time. Microsoft’s hosted option is £7.16 a month cheaper than the raw machine you would build to replace it, which makes it one of the few line items in this article where the bundled option is genuinely the frugal one.
When to reject desktop tooling outright
If the only justification is that nobody has asked the vendor for an API, ask first. A supplier portal that adds a CSV export removes £1,983.60 a year from your run rate permanently. Screen-driven robotic process automation should be the last option considered, not the first one demonstrated, and any proposal that leads with it deserves the question of what was tried before.
Business Process Automation Cost Across Zapier, Make and n8n
Microsoft is not the only answer, and for a firm without a Microsoft 365 tenant it is rarely the cheapest starting point. The difficulty is that no two vendors meter the same unit.
Units are not comparable, so here is the conversion
A Zapier task is one step. A Make credit is one module action. An n8n execution is an entire workflow run with unlimited steps. A Power Platform request is one connector call or built-in action. Comparing the headline prices tells you almost nothing; comparing what a single twelve-step workflow costs to run tells you everything.
Dollar and euro prices are converted at £0.752252 per US dollar and £0.856410 per euro, derived from Microsoft’s own internal conversion — the same D2s v5 virtual machine in UK South is listed at $0.111, £0.0835 and €0.0975 an hour, which fixes both rates without a market feed.
| Entry paid tier | Listed | Per month | Included | 12-step runs/month | Per 1,000 runs |
|---|---|---|---|---|---|
| Zapier Professional | $19.99 | £15.04 | 750 tasks | 62.5 | £240.60 |
| Make Core | $9.00 | £6.77 | 10,000 credits | 833.3 | £8.12 |
| n8n Starter | €20.00 | £17.13 | 2,500 executions | 2,500 | £6.85 |
| Power Automate Premium | £11.50 | £11.50 | 40,000 requests/day | 101,333.3 | £0.11 |
| UiPath Basic | $25.00 | £18.81 | Not published | — | — |
The gap the headline prices hide
Power Automate Premium covers 1,621 times more twelve-step workflow runs per month than the entry Zapier tier, and costs £3.54 a month less. That is not a criticism of Zapier, which is built for connecting apps a few hundred times a month and is superb at it — it is a warning that the tools are priced for completely different volumes and the sticker price does not reveal which is which. If your business process automation cost model is built on a monthly subscription figure alone, it is built on the least informative number the vendor publishes.
The self-hosting option nobody quotes
n8n publishes a self-hosted community edition under a fair-code licence, and for a firm with somewhere to run it the software line goes to zero. It does not go to zero overall — you have now bought a server, a backup, a patching routine and someone who understands all three — but on a workflow automation programme with heavy volume and thin budget, it is the option most likely to be missing from a proposal you did not ask to include it.
Cutting the Licence Stack Without Cutting Scope
The first quote for the six-process programme carried £11,253.60 a year of licences. The same six automations, unchanged in function, can run on £5,946.00.
| Line | As quoted | As optimised | Saving | Why |
|---|---|---|---|---|
| 2 x Process licence | £2,767.20 | £0.00 | £2,767.20 | 4 and 7 triggering users, both under the 10.03 crossover |
| Premium user licences | £2,070.00 | £2,484.00 | −£414.00 | 15 seats become 18 to replace the two Process licences |
| Hosted Process licence | £1,983.60 | £1,983.60 | £0.00 | Genuinely required — the portals have no API |
| Power Apps Premium x 8 | £1,478.40 | £1,478.40 | £0.00 | Includes flow rights inside the app — do not licence twice |
| Dataverse capacity, 3 GB | £1,108.80 | £0.00 | £1,108.80 | Documents belong in SharePoint, not a £30.80/GB database |
| Copilot Studio | £1,845.60 | £0.00 | £1,845.60 | None of the six processes needs a conversational front end |
| Total per year | £11,253.60 | £5,946.00 | £5,307.60 | 47.2% removed |
The business process automation cost pattern in those savings
None of them changed what the automations do. Three of the four came from licensing the right unit — people instead of flows, SharePoint instead of a database, nothing at all instead of a chat interface nobody requested. Reviewing the licence stack is the highest-return hour anybody will spend on a business process automation cost, and it needs doing again every renewal, because seat counts drift upwards and never drift back. Our guide to ongoing automation maintenance cost and governance covers the annual review in more depth.
The one place to spend more, not less
Do not economise on the non-production environment. A separate development and test environment costs nothing in licence terms on Power Platform and is the only thing standing between a change to a live flow and a Monday morning where 340 invoices went to the wrong approver. That is a cybersecurity and control argument as much as a financial one.
Three Processes or Six: The Business Process Automation Cost Comparison
Here is where the whole model earns its keep. Building only the three processes that cleared their break-even, and deferring the three that did not, produces this.
| Measure | Three processes | All six processes | Difference |
|---|---|---|---|
| Build days | 41 | 72 | 56.9% |
| Build fee at £450/day | £18,450.00 | £32,400.00 | −£13,950.00 |
| Licences per year | £1,932.00 | £5,946.00 | −£4,014.00 |

The business process automation cost finding worth taking to a board
Half the spend returns nearly three times the money. The three-process programme retains 70.4% of the hours for 56.9% of the build days, and turns a nine-percent three-year return into a fifty-three-percent one. Every pound of business process automation cost removed from the three failing processes is a pound that was going to earn less than nothing.
Why the bigger programme still looks attractive on paper
Note that the six-process net benefit per year is higher — £12,808.89 against £11,916.44. A supplier quoting annual benefit rather than payback is not lying; they are choosing the metric that favours scope. Ask for payback and three-year net position, and the ranking reverses immediately.
Where Three Years of Business Process Automation Cost Actually Goes
Split the £32,548.50 three-year total for the recommended programme and the shape is not what most budgets assume.
The business process automation cost nobody budgets: 43.3%
Change and licences together are £14,098.50 across three years — 43.3% of the three-year business process automation cost, and almost none of it appears in the document the board approves. A business process automation cost approved as a capital build fee and then funded month by month out of an operating budget nobody agreed is the most common way an otherwise sound programme acquires a bad reputation.
Why the change budget is 15% and not zero
Fifteen percent of build effort per year is the figure that survives contact with reality: a finance system upgrade, a supplier changing their invoice template, a new VAT treatment, a starter who needs the approval matrix altered. Assume zero and the first change request becomes an argument. On the three-process programme that is 6.15 days a year — about one day every two months, which is roughly what these systems actually consume.
The Business Process Automation Cost Items Missing From Most Quotes
Four lines are absent from the majority of proposals we are asked to review, and all four are real money.
Exception handling is most of the build
A 74% straight-through rate means 26% of sales orders still need a human. Somebody has to design where those land, who chases them and what happens at 5pm on a Friday. Exception design is routinely a third of the build effort and is the first thing cut when a supplier is squeezing a fixed price into a budget — which is precisely why fixed-price automations so often arrive working perfectly on the happy path and nowhere else.
The people cost on your side of the table
The 114-day figure covers the supplier’s effort, not yours. Expect your process owners to spend 12 to 20 days across a six-process programme in workshops, test scripts and sign-off. At the £19.3128 loaded administrator rate that is between £1,738 and £2,897 of internal time, and it is time those people are not spending on their day job.
Decommissioning the thing you replaced
If the automation replaces a spreadsheet, an Access database or a paid third-party tool, the saving only lands when the old thing is switched off and its licence cancelled. Put a date on it in the plan. Automations that run alongside the manual process “for a few months” have a habit of doing so for years, at which point the business process automation cost has doubled and the benefit is still zero.
The leaver problem
Every automation is owned by an account. When that person leaves, connections break and flows stop silently. Service accounts, documented ownership and an alert when a flow fails twice in a row are cheap to build at the start and painful to retrofit. Our write-up on why automation projects fail puts ownership at the top of the list for exactly this reason.
What a Credible Business Process Automation Cost Proposal Contains
You can assess a proposal in ten minutes with this list. Anything missing is a question, not necessarily a problem.
The six things every business process automation cost must show
| Item | What good looks like | Warning sign |
|---|---|---|
| Effort and rate, separately | “84 days at £450” | A single total with no day count |
| Named licences and quantities | “18 x Premium, 1 x Hosted Process” | “Licensing to be confirmed” |
| Straight-through rate per process | A stated percentage you can test | “Full automation” |
| Exception handling design | Named owner, queue and escalation | Not mentioned at all |
| Annual change allowance | A day count and a rate | “Support included” |
| Break-even volume per process | Arithmetic you can reproduce | A benefit figure with no method |
The question that settles any business process automation cost
Ask: “at what monthly volume does this process stop being worth automating?” A supplier who has done the work answers in seconds. A supplier who has not will tell you that automation always pays back, which is the single clearest signal in this entire market that the business process automation cost in front of you was set by what they thought you would accept.
Business Process Automation Cost Mistakes UK Firms Keep Making
Five patterns account for most of the money wasted, and none of them are technical.
Automating the loudest process instead of the largest
The process everybody complains about is rarely the one with the volume. Month-end is the classic: eleven hours of visible pain, twelve times a year, failing its break-even by £507.49.
Adding discovery tooling to a business process automation cost that cannot carry it
At £46,137.60 a year, the mining add-on has to find £46,137.60 of waste before it breaks even, in a business whose entire recoverable labour value is £23,614.89. Some tools are simply not sized for your organisation.
Licensing flows when you should licence people
The 10.03-user crossover is public arithmetic and it is got wrong constantly, usually because a per-flow licence sounds tidier on a diagram.
Treating intelligent automation as a licence you buy
Adding document AI, a conversational front end or agent tooling to a process that has not passed its break-even does not rescue it — it raises the annual cost and therefore the volume required. Intelligent automation is a multiplier on a business process automation cost that already works, not a repair for one that does not.
Counting saved hours as saved money
0.7182 of a full-time equivalent is a real operational gain and it is not £23,614.89 of cash unless somebody’s job actually changes. Say which: redeployment, avoided recruitment, or reduced overtime. A benefit case that cannot name the mechanism will not survive its first budget review, and the automation gets blamed for a claim it never made.
Business Process Automation Cost: Frequently Asked Questions
What does it cost to automate one process in the UK?
For a straightforward cloud-based workflow, budget 6 to 20 days of build at £450 to £705 a day — roughly £2,700 to £14,100 — plus £138 per user per year in licences and a change allowance of 15% of build effort. The three-year business process automation cost for a single mid-sized process in this model was £4,032 a year all in.
How long before automation pays for itself?
In the recommended three-process programme, 18.6 months. Across all six candidates it stretches to 30.4 months. Anything a supplier describes as paying back in under six months is either a very high-volume process or a benefit case that has quietly excluded licences and change.
Is Power Automate cheaper than Zapier?
At volume, dramatically. A Premium licence covers 1,621 times more twelve-step workflow runs a month than the entry Zapier tier, for £3.54 a month less. At low volume the answer flips, because Power Automate assumes you already pay for a Microsoft 365 tenant and Zapier does not.
Do we need a full-time automation developer?
At ninety people, almost certainly not. The three-process programme consumes 41 build days and then 6.15 days a year. That is a fractional need, best met by a partner retainer or a contractor on call rather than a £64,150 loaded salary sitting mostly idle.
What is a realistic straight-through rate?
Between 60% and 90% depending on how clean the input is. The six processes here range from 60% for credit-checked onboarding to 90% for portal downloads. Any proposal assuming 100% is describing a system that has never met your suppliers.
Should we build once and stop?
No, and budgeting as though you will is the most expensive assumption in this article. Licences and change are 43.3% of the three-year total. Plan the run rate before you approve the build, and review the licence stack at every renewal.
