# Service Terms Changed

> A selected service price or duration changed before the appointment was created

## Cause

A selected service price or duration no longer matches the booked barber's current public catalog. The appointment was not created.

## Fix

Refresh the barber's public services, show the current terms to the customer, and retry with a new idempotency key after the customer confirms them.

## Retry safety

Not retryable until the underlying state or request changes.
