Microsoft has delayed the date when usage-based billing turns on by default for new Microsoft 365 Copilot Business subscriptions bought through CSP — it now lands in Microsoft’s FY27 Q3, January through March 2027, instead of December 1, 2026. The mechanics are unchanged: the default spending limit is 4,000 Copilot Credits per user per month, pay-as-you-go is the default billing configuration, and a new purchase enables usage-based billing for existing Copilot Business licenses in the same tenant. If you’re adding Copilot Business seats this winter, the delay buys time to decide your credit limits before consumption charges can start — ask your partner to confirm the exact timing and the limits set on your tenant in your quote.
