How much does automatic checking of invoices against orders cost, and when does it pay back?
Short answer
Automatic checking of invoices against orders costs from €3,000 net. In our scenario it pays back in 2 months. Today, checking 600 invoices against orders by hand costs €1,745 a month. With the system, the same work costs €264. The buyer decides whether a difference needs clearing up. The system finds it sooner than a person would at the hundredth invoice. The test on your process is free.

The team gets back about 42 hours of work a month, or 5 working days, and the company €17,772 a year. We count after the time a person spends checking and after the model cost.
600 × 5 min = 50 h × €34.90 = €1,745 a month. With the system, a person checks the output in 15% of the old time (€262) and the model costs €2.52. That leaves €264. The saving is €1,481 a month, so €3,000 pays back in 2 months.
Assumptions: 5 minutes per invoice (order, terms, earlier invoices) and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. We measured the model cost of €0.004 per invoice in our invoice coding system, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.
What stays with people: The buyer decides whether a difference needs clearing up. The system finds it sooner than a person would at the hundredth invoice.

Our invoice coding system separately checks that the invoice matches the order and the delivery confirmation, and holds an invoice with a blocking difference, giving the reason. Demonstrator on synthetic data.

What happens to your data
You choose the test cases. We anonymise them on request.
They stay in the EU and we delete them after the test.
We sign the NDA and the data processing agreement before we receive anything.
After acceptance you keep the code, the test set and the documentation. You pay for licences and model usage directly to the provider. With several departments or companies, the engineer suggests a Process Audit from €600 net: a map of the flow and a fixed quote. We deduct the audit fee from a build signed within 3 months.
Questions
How much does automatic checking of purchase invoices cost?
From €3,000 net, paid once. After the 5-day test the build takes 2 to 6 weeks. You get a fixed price before the contract: 50% on signing and 50% after acceptance on your own invoices.
Would the matching in our ERP be enough?
If your suppliers' invoices match orders one to one, the matching in your software is usually enough. The system makes sense when several invoices relate to one order and the terms sit in contracts and emails.
When does it not pay off?
Below 110 invoices a month the payback takes more than a year. Then it is better to start with ChatGPT or Claude for the department, from €1,150 net.
Who sends the question to the supplier?
The buyer. The system prepares a draft with the order number and the difference, and the buyer approves or corrects it before it goes out.
What do we need to prepare?
20 to 100 invoices with their orders from recent months, including ones with a difference, and the price terms from your main suppliers.
What our OpenAI and Anthropic partnerships mean for you.
OpenAI makes ChatGPT and Anthropic makes Claude. We belong to the partnership programs of both companies, so we work with their tools every day and learn from the creators themselves.
Claude Partner Network
01We will select a tool for the task
We implement both ChatGPT and Claude. We check both on your documents, and you choose the one that makes fewer corrections and saves more time.
02Knowledge straight from the creators
We learn from official OpenAI and Anthropic courses and materials. Your team learns about the features and settings that work today.
03Licenses without our margin
You buy accounts directly from OpenAI or Anthropic and receive an invoice from them. We do not add anything to the license.
04Certified engineers
On the team, we have an AWS certification in machine learning and an Anthropic certification in systems architecture on Claude.
Participation in programs does not mean that OpenAI or Anthropic endorses our services.
