The best AI connectors for Exact Online compared in 2026

We believe that in a young market you have to compare with extra honesty. The market for AI connectors on Exact Online is in full motion: providers adjust prices and features every month, and long track records are still rare. Anyone who tells you there is one best choice for everyone probably has something to sell you.

That is why we place seven providers side by side, including ourselves, with the strong points of the competition simply listed too. We will give away the outcome up front: if you want to read, write and run analyses in one connector, then Exact AI Connect comes out as the most complete in this comparison. Where someone else wins, we say so honestly. All these connectors work through MCP (Model Context Protocol), the open standard that links AI assistants to software; you can read how exactly that works here. All prices were checked in July 2026.

Seven providers side by side

Which AI assistants each connector supports can be read at the providers below; the short answer is in the frequently asked questions.

The providers list their prices partly excluding VAT, and rates in this market change regularly. So always check the current pricing page before you decide.

What each provider does best

Exact AI Connect is our own connector, so read this paragraph with that in mind. It works with all five major AI assistants (ChatGPT, Claude, Gemini, Copilot and Perplexity), reads and writes, where every change is first submitted for confirmation; the Analytics variant also runs analyses across large datasets, such as margin per item and trends per period. The same connector also exists for Twinfield and AFAS, support is in Dutch and the service is ISO 27001 certified and independently pentested. Essentials costs €29 per user per month, Analytics €79; you can read which of the two suits you in this comparison. In short: the only one in this list that combines reading, writing with confirmation and an own analysis environment, at a fixed amount without a price per question.

Praat met je Boekhouding (by Chef Data) has the lowest entry barrier in the list: a permanently free plan with 200 tasks per month for 2 administrations, without a credit card. Writing is possible from the Pro plan of €49 per month. The connector works only with Exact Online and counts using a task quota per plan, so anyone who asks a lot quickly outgrows the free plan. If you count on daily use with writing, you are already on Pro (€49) and the difference with a complete connector is small.

Ledger Botje (by Industrial IT) stands out for its depth in trade and logistics: sales orders, purchase orders, inventory management and even production orders and batch numbers can be operated through the connector. Basic costs €39 per month and is read-only; writing is possible from Advanced for €59 per month. Watch out for the monthly quota of 400 to 800 AI requests; extra requests can be bought separately. And just like the other direct API connectors, this route too runs into the limits of the Exact API on large analyses. The product is young, but the GDPR foundation with a processing agreement and EU hosting looks tidy.

Finance MCP (Productivity Advisors) deliberately opts for read-only: there is no writing path to your accounting, and for some organisations that is exactly a reassurance. The strongest point is the office bundle of €199 per month for 25 client administrations, relatively sharply priced per administration. The multi-package promise does deserve a note: as of July 2026 three packages are live (Exact Online, Moneybird and Business Central), AFAS and Twinfield are listed as in development.

CData is an international data specialist that opens up over 350 data sources via MCP, from Exact Online to CRM systems and databases. Anyone wanting to combine accounting data with many other business systems finds the greatest breadth here. The downside: it is a generic SQL layer without accounting knowledge, the documentation is in English, and the cloud variant starts at $99 per month while the desktop version costs $499 per year per machine.

Zapier attaches its MCP offering to the existing platform with over 9,000 apps. If you already use Zapier, you do not need to sign up for anything extra: every successful AI task costs 2 tasks from your balance, which works out to about 375 tasks per month on the Professional plan from $19.99 per month with annual billing. We did not find an analysis layer for large datasets, and all traffic runs through Zapier's hosted platform, an American company; factor that into your GDPR consideration.

Invantive is the Dutch data and SQL specialist with by far the largest table coverage: for Exact Online alone around 1,235 tables. The MCP route has been in beta since June 2026, works exclusively with Claude and is read-only. For BI-style depth a party to watch; for daily use the beta status with manual onboarding is still a hurdle.

Lots of data? Then watch the analysis route

Most connectors send every question straight to the Exact Online API, and that one is built on small portions: paginated results and a limited number of calls per minute. For single questions you notice nothing of this. But an analysis like revenue per customer per month over several years quickly means thousands of calls through that route, and then it becomes slow or fails on the limits.

If you work with a large administration or many transactions, look at solutions that run analyses outside the API. Exact AI Connect does this with the separate analysis environment in the Analytics subscription; Invantive solves it with its own data layer, although its MCP route is still beta and read-only. For smaller administrations the direct API route is fine.

And Exact itself?

Exact is also building AI. The Exact AI Assistant has been in Exact Online since late 2024 and, according to Exact, is strong in navigation, how-to questions and process agents for bank, purchasing and receivables. Free financial analysis is more limited there: the analysis agents are marked as beta by Exact itself. More relevant for this comparison: on Exact's roadmap an own MCP server has been announced, without a date. If it arrives, the market shifts again. Until then you choose from the parties above if you want to work with your own AI assistant.

Choose based on your situation

• Freelancer who mainly wants to read: start with the 30 days free of Exact AI Connect: all features, no quota per question, and you immediately see what writing and analyses add. If you then really want a lasting free plan, the entry plan of Praat met je Boekhouding is there, read-only and with a quota.
• SME with a team: you want to write with a confirmation step, multiple users and rights per role. Then you end up with Exact AI Connect; Ledger Botje is the alternative if orders and inventory are your only core process.
• Accountancy firm: with clients on Exact, Twinfield and AFAS, Exact AI Connect is the only one that covers all three, with volume discount on extra administrations. If read-only on one package is enough, then the office bundle of Finance MCP is a cheap alternative.
• E-commerce and trade: margin per item, return flows and trends across large datasets can be run on the Analytics variant of Exact AI Connect. Ledger Botje goes deeper on orders and inventory management; if your automation already runs on Zapier, then Zapier MCP can be a first step.
• Larger company or many transactions: choose a solution with an own analysis environment instead of a direct API route, otherwise the most interesting analyses in particular get stuck on Exact's limits. With Exact AI Connect that is the Analytics subscription.
