Extended Service Terms (EST) is an end-of-term option in the Microsoft CSP new commerce program. Instead of renewing or canceling an expiring license-based subscription, a partner can move it to EST, a paid, flexible month-to-month term that keeps the customer's service running and can be canceled at any time.

Key Takeaways

EST is one of three end-of-term choices: renew, cancel, or move to EST.
It is a paid, month-to-month continuation that can be canceled at any time.
It prevents accidental service loss when a subscription reaches its end date.
Enforcement has been in effect since May 4, 2026, so eligible subscriptions can move to EST automatically.

How EST works

When an eligible subscription reaches the end of its term, it can renew, cancel, or continue on an EST. EST subscriptions run as flexible monthly terms, can be canceled at any point, and can be converted back to a standard SKU or upgraded. Under the enforced rules, subscriptions that were purchased or renewed on or after April 1, 2025, expire on or after May 4, 2026, and have auto-renew off will move to EST at expiration unless the partner sets renew or cancel first.

Why it matters for Microsoft CSPs

EST is a safety net against unexpected service disruption, but it is also a billing event. If a partner does not manage end-of-term choices, subscriptions can move to EST and continue billing when the partner intended to renew or cancel. Proactive end-of-term management is what keeps billing predictable.

EST vs renewal vs cancellation

Renewal commits to a new term. Cancellation ends the service at the end date. EST keeps the service running month to month, paid, until the partner renews, converts, or cancels it.
