What AI over Business Central costs for each user

Start with the part that costs nothing extra. Copilot in Business Central is included with your Business Central licence at no extra cost. Microsoft states this directly, and adds that fair-use policies, quotas or pricing might be introduced later.

So the question is not "what does AI on Business Central cost?". It is "what does the work Copilot does not do cost, and how do I stop that bill from surprising me?".

What is already in your licence?

Copilot, and the built-in agents. The Sales Order Agent, the Payables Agent and the Expense Agent are part of Business Central online. Check the state of each agent before you plan around it, because the 2026 release wave 1 plan listed the Expense Agent entries in public preview.

One figure causes regular confusion. Business Central licences include 30 minutes of Azure AI time. Microsoft states that this quota refers to non-Copilot features such as sales and inventory forecasting, and that consumption of Azure AI time has no effect on Copilot in Business Central. It is not a Copilot allowance, and running out of it does not stop Copilot.

What sits beside it, and how is it priced?

A separate assistant is priced per named user, per month or per year. Seats are handed out in a portal and can be moved between people, so you pay for seats held rather than accounts that exist.

UNI4C sells four licences, and the current prices are on the pricing page with a calculator.

Two rules shape the arithmetic. Report authoring is an add-on and requires a Controller seat for the same person, so releasing the Controller seat releases the authoring seat with it. And every licence is cheaper by the year: a year costs about eleven months.

How should you size it?

Most companies get this wrong in the same direction. They buy Controller seats for everybody and then find that most people ask questions that a Support seat answers.

A pattern that works:

1. Start with the people who ask the questions. Usually the controller, the finance manager, and one or two operations leads. These need Controller seats.
2. Give everybody else Support. Help on the page they are stuck on, and the ability to open a report somebody else built, covers most of a company.
3. Add report authoring for the one or two people who build. Reports get shared with readers who do not need an authoring seat.
4. Add App Builder when there is a real change to build. It is the largest line and it is project-shaped rather than seat-shaped.

Re-check after a month. Seats move between people, so an over-buy is a correction and not a loss.

What about the AI usage itself?

This is where an AI bill becomes unpredictable in most products, so it is worth understanding the mechanism rather than the number.

Each seat carries an included AI allowance. Spending past the allowance is never automatic. A company administrator has to switch extra usage on, for the company, for a role or for one person, and can set a cap on each.

Until somebody does that, the allowance is the ceiling. When the month is spent, the answer is that the month is spent. Nobody receives a larger invoice than they agreed to.

That default is deliberate. The common failure in AI pricing is a bill that arrives after the spending, from a system that nobody told to stop. Making overspending an explicit decision, with a cap, removes that failure.

What is the total cost of a decision?

Licence cost is the visible part. Three others are real.

The Business Central extension. Connecting Business Central takes one extension, which a company administrator installs from the portal or uploads in Extension Management. Schedule it, because a production environment is interrupted while it runs.

Setup time. Connections, seats and the first reports. This is hours, not weeks, but it is not zero.

The consultant. For App Builder work, every session ends as a change your consultant reviews. Budget for the review, because the review is where the value is protected.

The comparison that matters

Compare against the work, not against Copilot.

Copilot is included, so it has no incremental cost and it does its own work well. A second product has to earn its price against something else: the hours that people spend pulling numbers out of Business Central by hand, the reports that a consultant builds and rebuilds, and the decisions that are made on a figure nobody verified.

If your controller spends a day a month assembling numbers that a query could answer, one seat pays for itself. If nobody does that work, the honest answer is that you do not need this yet, and Copilot is enough.

Trials

Each product carries its own trial, and the portal shows that product's trial terms before anything is committed. A trial that is not converted ends by itself.

Use the trial on your own data rather than on a demonstration tenant. The question you need answered is not whether the product works. It is whether it answers your questions, in your company, with your definitions.
