Local AI model for accounting firms: client documents stay in the office

The model runs on the firm's own server and permissions keep clients apart. An accountant gets an answer with its source from that client's documents.

How much does a local AI model for an accounting firm cost, and when does it pay back?

Short answer

A local AI model for an accounting firm is priced after a call. The EU cloud version costs from €3,000 net. In our scenario it pays back in 1 month. Today, the work on 800 questions costs €3,723 a month. In that version the same work costs €570. Tax interpretations and accounting decisions stay with the accountants.

We price the model on your server after a call, with the build, the hardware or hosting and the maintenance quoted separately. The same work in an app with a model in the EU cloud costs from €3,000 net, paid once. That version gives the team back about 91 hours of work a month, or 11 working days, and the company €37,836 a year.

How we calculate it

800 × 8 min = 106.7 h × €34.90 = €3,723 a month. In the EU cloud version, a person checks the output in 15% of the old time (€558), and the model costs €12. That leaves €570. The saving is €3,153 a month, so €3,000 pays back in 1 month.

Assumptions: Our assumptions are 8 minutes to find an agreement in a client's documents, 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 in the EU cloud version, at the ECB rate of 1.1205 USD per euro on 22 October 2026. We count the payback for an app with a model in the EU cloud (from €3,000 net). We price the model on your server after a call, and the cost of people's work stays the same.

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

What this scope builds on

The in-network document workflow we have already built

Documents, search and the model stay inside the company network, and each answer points to its source. In the recorded run 3 answers were produced locally on a GPU with a median of 430 ms, with no fees for an external API. Demonstrator on synthetic material.

Client review

“We started with my own AI agent. During the training that followed, I learned to build new applications myself. Today I am bringing this way of working with AI into my business. Working with Syntalith gave me exactly the skills and tools I needed.”

Included in the build

  • Model selection and evaluation on your own examples
  • Setup on your own hardware or in the EU
  • Document search with sources and permissions
  • User guide and maintenance plan

What happens to your data

  • Documents, search and the model stay in your network.
  • We plan the trial on agreed examples before you buy the target hardware.
  • Where personal data is involved, we sign a data processing agreement first.

After the rollout you keep a working model with its configuration, the test results, a user guide and a maintenance plan. We quote hardware or hosting separately.

Questions

  • How much does a local model cost?

    We quote once the scope is agreed, with the build, the hardware or hosting and the maintenance priced separately. The same work in an app with a model in the EU cloud costs from €3,000 net, paid once.

  • Is a local model as good as ChatGPT?

    We test it on your own examples before you buy hardware. We compare the quality, the response time and the full cost of the local model with a cloud service.

  • How do you keep clients apart?

    With permissions: an accountant sees only the clients they handle, and a document from any other client never reaches the search.

  • When does it not pay off?

    An app with a model in the EU cloud is usually cheaper when the documents may go there under a data processing agreement. Below 70 questions a month the payback takes more than a year. Then start with ChatGPT or Claude for the team, from €1,150 net.

  • What do we need to prepare?

    Your client folder structure, the list of staff with their assigned clients and 30 to 50 typical questions.

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.
