MCP or Zapier: what to pick for Exact Online?
The difference is not what is possible, but who decides the steps. With an iPaaS platform such as Zapier, Make, n8n or Power Automate you define a fixed chain up front that then runs exactly the same way every time. With an MCP integration like Ledger Botje you ask a question or give an instruction in plain language, and the AI assistant works out per request which steps are needed.
Pick iPaaS for work that is identical every day and has to run without a person. Pick MCP for work that differs each time and where someone is watching. They do not compete: plenty of companies run a fixed order flow through Zapier and use Ledger Botje for the questions and exceptions around it.
The differences side by side
| Ledger Botje (MCP) | iPaaS (Zapier, Make, n8n, Power Automate) | |
|---|---|---|
| How you work | You ask a question or give an instruction in plain language | You build a scenario with triggers and steps up front |
| Who decides the steps | The AI assistant, per request | You, once, at build time |
| Start without setup | Yes, right after connecting | No, every scenario has to be built first |
| Unforeseen questions | No problem, you simply ask | Only if a scenario exists for it |
| Runs unattended | No, someone holds the conversation | Yes, that is the whole point |
| Predictability | Varies per run; check the outcome | Every run identical |
| Reacting to events | Not on its own; you start the conversation | Yes, through triggers and webhooks |
| Exact Online actions | 292 MCP tools | Whatever that platform's connector offers |
| Cost model | Fixed amount per month | Usually per task or per run |
Pick iPaaS (Zapier, Make, n8n) when...
- the step is always the same: every new webshop order becomes a sales order.
- it has to run while nobody is watching, at night or over the weekend.
- an event in another system is the trigger, not a person.
- you want exactly the same outcome on every run, without variation.
Pick an MCP integration when...
- the question differs each time: "which customers bought this item and then ordered nothing else?"
- you do not know up front which steps lead to the answer.
- you want to investigate or verify something rather than run a fixed chain.
- you would rather not build a scenario for something you do twice a year.
Why an iPaaS scenario stalls on exceptions
A scenario is a decision tree you drew up front. As long as reality fits that tree, it works beautifully. The moment a case falls outside it - an order with an item that does not exist, a supplier under a slightly different name, an invoice that will not match - the scenario stops or does something you did not want.
That is not a flaw in the platform but the nature of predefined automation. The exceptions land on an error list that someone has to work through by hand. That handwork is exactly what an AI assistant with an MCP integration can help with, because it can investigate each case on its own terms.
Can you use both?
Yes, and it is often the smartest setup. Let the predictable volume run through an iPaaS scenario: importing webshop orders, sending standard invoices, moving files. Use the MCP integration for the layer above it: working through the error list, judging an unusual order, answering a question nobody has built a scenario for.
Both connect to the same Exact Online administration. They do not know about each other and do not need to.

Can Ledger Botje react automatically to a new order, like Zapier?
No, not by itself. An MCP integration is addressed by an AI assistant during a conversation, so there is always someone asking or instructing. If you want something to happen the moment an order arrives, unattended, an iPaaS scenario or a webhook is the right choice.
Is Zapier cheaper than an MCP integration?
It depends on volume. iPaaS platforms typically charge per executed task, so cost rises with transaction count. Ledger Botje costs a fixed amount per month from €39 with a monthly allowance of AI requests. At high, predictable volumes per-task is often more expensive; for occasional investigative work a fixed amount is.
Why not just a Zapier scenario with an AI step?
You can, but then the scenario still decides which data the AI gets to see. An MCP integration gives the assistant access to the tools themselves, so it can decide mid-conversation to look something else up. That is precisely the difference for questions whose steps you cannot know in advance.
Does Ledger Botje work together with Power Automate?
Not directly, but they do not conflict. Power Automate connects to Exact Online through the regular API, Ledger Botje through MCP. You can attach both to the same administration; Microsoft Copilot can moreover use the MCP integration itself.
