Copilot’s two bills: Preparing for Microsoft's usage-based billing

Copilot used to be easy to budget for: one licence, one price, everyone covered. That era is ending. Microsoft has split Copilot into two bills, a fixed seat for everyday AI and a meter for the agentic work you hand off, and by the end of 2026 most advanced AI will run on that meter.

Early adopters are already feeling it. A single power user can cost nearly seven times their seat, prepaid credits roll quietly into pay-as-you-go, and for many the first invoice is the first warning.

This white paper explains what’s changing and when, what a task and a user really cost, and the seven lessons practitioners keep learning. It closes with twelve practical actions to put guardrails in place before the meter reaches your tenant.
