What your manual processes cost per year, and how to calculate it

Ask a managing director what an hour of office work costs and you usually get the gross hourly wage. That number is too low. Germany's Federal Statistical Office (Destatis) puts the average cost of an hour actually worked in the private sector at €45.00 for 2025. In wholesale and retail trade it was €37.20, in transport and storage €35.80, in health and social work €41.70. The gap comes from two places: employer contributions on top of the wage, and the holidays, public holidays and sick days you pay for while nobody works. If you want to calculate the cost of manual processes honestly, start from these figures.

How to calculate the cost of manual processes

You need three numbers and a rate: cases per day, minutes per case, working days per year. Multiply them, convert to hours, then multiply by the hourly cost.

The minutes are where estimates go wrong. People remember the typing. They forget looking up the customer number, the email asking for a missing reference, the wait for the reply and picking the case up again an hour later. So measure it. One week with a tally sheet at a single desk is enough: time started, time finished, and a mark whenever a case bounced back.

For the rate, use your own figures if you have them: the total annual employer cost of the position divided by the hours actually worked. If you don't, the Destatis figure for your sector is a fair stand in.

A worked example from a haulier

Suppose a haulage company receives 50 subcontractor invoices and delivery confirmations a day. Someone checks each one against the transport order and keys it into the accounting system. The tally sheet shows eight minutes per document, lookups included. These figures are illustrative.

50 documents at eight minutes is 400 minutes, just under seven hours a day. Over 220 working days that comes to about 1,467 hours. At €35.80, the transport and storage rate, the transfer alone costs around €52,500 a year.

Then come the errors. Say 4 percent of documents are keyed wrongly or matched to the wrong order, and each correction takes 25 minutes: spotting it at month end, rebooking, sometimes a call to the subcontractor. That's two cases and 50 minutes a day, 183 hours a year, another €6,560.

Together it adds up to roughly €59,000 a year for one workflow that most people in the office would call "just admin".

What the formula leaves out

Waiting time, for one. A document that sits in a pile until Thursday costs no extra minutes, but everything after it moves later. Invoices to your own customers go out later, so the cash comes in later. On the payables side you can see it directly: if a €5,000 invoice offers 2 percent discount for payment within ten days and the approval stalls, €100 is gone and nobody records it as a loss.

Then there is the work that doesn't get done. Those 1,467 hours belong to someone who could be chasing overdue payments or getting the month-end close finished on time. Nobody can put an honest number on that, but you know what you hired those people for.

The same arithmetic works in wholesale, for order entry and order confirmations at €37.20, and in hospitals, for medication and implant orders or bed management reports at €41.70. In a hospital every admin hour an agent takes over is an hour the team gets back for patients.

What to do with the number

The annual figure is the ceiling for what automation can save. Depending on the process, we cut 20 to 80 percent of process costs with an agent. In the example that means roughly €11,800 to €47,300 a year. Where a workflow lands in that range depends mostly on how many cases go through without a query.

Set the fixed price against that, plus running costs. With us, running costs are only the usage fees of the AI models, billed directly to you, with no subscription and no operating fee. A maintenance agent that watches the interfaces is included in the fixed price. An agent is set up in one to two days and tested on real cases the same week, so you find out early whether the numbers hold in your business.

Where to start

Pick the workflow people complain about most and keep a tally for one week. Count cases per day, minutes per case and the share that needed a correction, then multiply by your sector rate. That gives you a figure to hold every offer against, ours included.

In the free automation check, Sophera Consulting runs that calculation with you for one process, works out which workflow makes sense to start with, and then sends you a fixed price offer with a cost-benefit analysis.
