The team gets back about 64 hours of work a month, or 8 working days, and the company €26,640 a year. We count after the time a person spends checking and after the model cost.
300 × 15 min = 75 h × €34.90 = €2,618 a month. With the system, a person checks the output in 15% of the old time (€393), and the model costs €5. That leaves €398. The saving is €2,220 a month, so €3,000 pays back in 1.4 months.
Assumptions: Our assumptions are 15 minutes to find the right template and check where it comes from, and checking in 15% of the old time. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: Claude Sonnet 5.5, about 6,000 + 500 tokens per answer from documents, at the ECB rate of 1.1205 USD per euro on 22 October 2026.

Questions
How much does a private ChatGPT on company documents cost?
From €3,000 net, paid once. After the 5-day test the build takes 4 to 10 weeks. You get a fixed price before the contract: 50% on signing and 50% after acceptance on your own questions.
Can the firm's documents stay on our own server?
Yes. We can run the app with a model on the firm's own infrastructure. We describe this on the private models page.
When does it not pay off?
Below 40 questions a month the payback takes more than a year. Then it is better to start with ChatGPT or Claude for the team, from €1,150 net, with projects on your own documents.
What do we need to prepare?
Your template library with the people who approve each template, the rules for reuse and 30 to 50 typical searches.
