What AI automation actually costs a small firm, and what drives the number

The four things that move the number

Two automations that sound identical in a meeting can differ by a factor of five, and it is never the model that does it. Ask any supplier to price these four things separately and you will learn more about the quote than any breakdown by hours will tell you.

1. How many systems it has to touch. One system with a documented interface is a small job. Three systems, one of which is a practice-management tool with no interface at all, is a different job wearing the same description. The count matters less than whether each one can be read and written to without a human in the loop.
2. Whether the process is stable enough to automate. The test is whether two of your people would do it the same way today. If they would not, you do not have a process, you have a habit with variations, and automating it locks in whichever variation happened to be in the room. That is a discovery cost before it is a build cost, and honest suppliers charge for it.
3. What share of the work is edge cases. The normal path is cheap. The exceptions are the project. A pipeline where 90% of documents look alike and 10% do not is a reasonable build; one where a third of cases need judgement is a staffing question dressed as a software question.
4. Who answers when it breaks. Software that runs unattended fails eventually, usually because something upstream changed without telling you. Whether that is your problem, your supplier's, or nobody's until Monday is the single largest difference between two quotes that otherwise read the same.

What you are actually buying, line by line

An automation is four costs with four different shapes, and confusing them is how budgets go wrong. One is a fixed sum, one is a meter, one is a subscription, and one is invisible because it is paid in your own people's time. The last is the one that gets left out of every comparison and is often the largest.

The meter is the line people underestimate, and it is the easiest to check before signing anything. Automation platforms bill per task rather than per user, so the cost follows volume. Zapier, to take the one most small firms have already tried, publishes its entry tiers openly, and they are the figure below. Multiply your real monthly volume by whatever the equivalent is on your platform before anybody quotes you a build.

The three shapes the market sells, and when each is right

Almost every supplier you will speak to is one of three things, and they are not competing for the same firm. The mistake is not choosing the wrong one. It is not noticing that they are different products, and then comparing their prices as though they were the same.

Our answer to the third row's failure mode is written into how we sell, and you should demand the equivalent from anybody. Fixed scope, one named acceptance test that you write rather than we do, a working prototype in ten working days, and a care plan cancellable at thirty days. None of that is generosity. It is the only arrangement in which a fixed quote is safe for both sides.

What the ranked guides quote, and why it stays in dollars here

Search this question in English and you will get a wall of agency pricing guides, all American. They are worth reading as market context and worth nothing as a quote for a firm in Germany, because the labour cost, the currency, the tax treatment and the buyer are all different. We re-read two of the most visible on 14 August 2026, and both had moved from what our own keyword audit recorded weeks earlier. That is the strongest possible argument for treating any of these numbers as weather rather than as a price list.

The German context those pages have no way of carrying is the adoption curve, not the currency. The official statistics say the firms most likely to be reading this are the ones least likely to have done it, which changes what a first project is for. It is not catching up with your competitors. Most of them have not started either.

The arithmetic that replaces the rate card

Price is the wrong question and payback period is the right one, for a reason that has nothing to do with sales technique. A build that costs a lot and pays for itself in two months is cheap. A build that costs little and never pays for itself is expensive, and it is also the more common outcome. Four steps, in this order, and none of them needs a supplier in the room.

1. Put a number on the leak, before anybody quotes anything. Not a feeling, a monthly figure with the assumptions visible. Unanswered calls, slow first replies, empty appointment slots, invoice rekeying: each of those has a calculator on this site with every input exposed and the model shown rather than hidden.
2. Use your own hourly cost, not an industry one. The calculators default to bands of €35/h for office time and €60/h for the owner's, because those are the numbers the underlying model was built on. Change them to yours. If your time is worth more than the band, the payback is faster than the default shows, and if it is worth less, better to find that out now.
3. Divide the build by the monthly leak, and be suspicious of anything over a year. That quotient is the payback period in months, and it is the only number that makes two quotes comparable. Under three months, the decision is easy. Beyond twelve, something in the scope is wrong: either the leak is smaller than it felt or the build is bigger than it needs to be.
4. Then check the meter and the care plan against the monthly saving. A build that pays for itself in four months and then costs more each month than it saves is a subscription with an entry fee. Run the ongoing lines against the ongoing saving separately from the build, because they are separate decisions and suppliers benefit from them being blurred.

The calculator below runs step one for the most measurable of the four leaks. Invoice rekeying is the easiest to price honestly because every input is something you already know: how many supplier invoices arrive, how long each one takes to handle, and what the person handling them costs per hour. If the answer comes out small at your volume, the tool says so rather than nudging you towards a project. The benchmarks page shows where every default in it came from.

Why this site quotes one price and nothing else

There is exactly one number on this website, and it is €29. That is the Check: a same-day deep scan of where your firm is leaking, delivered as a punch list rather than a deck. Everything else is quoted after an analysis, in writing, as a fixed sum for a fixed scope. That is a deliberate position and it costs us traffic from people who wanted a price on a page, so it is worth explaining rather than asserting.

A published rate card is only honest if the work is genuinely standard. For a per-seat product it is: everybody gets the same thing, so everybody can see the same price. For work that crosses your particular systems, the number depends on the four drivers at the top of this page, and a rate card can only be built by guessing them. Publishing one means either quoting high enough to cover the worst case, which overcharges the simple jobs, or quoting low and recovering it later through scope changes. Both are worse for the buyer than a fixed quote after a real look.

And the cheapest possible version of this decision is to not buy anything yet. Run the calculators, get your own monthly number, and if it is small, do nothing. We would rather tell you that at the start than at the end. If you want somebody to do the looking properly, the €29 Check is what that costs.
