Explanation (150–250 words)

In Salesforce CPQ and Subscription Management, subscription cancellations cannot be backdated to a date earlier than the current date when the amendment or cancellation action is performed. This rule ensures data integrity between contracts, billing schedules, and revenue recognition.

In this case, the customer requested cancellation effective June 29, 2025, but the cancellation request was received on July 5, 2025. Salesforce enforces that the earliest possible effective date is the date the amendment or cancellation is executed—July 5, 2025—not any past date.

The only scenario where a contract can be canceled from the start date (June 20, 2025) is if the entire subscription term is voided before any billing or revenue recognition has occurred. Since the service was already active, that option isn’t valid.

Exact Extract from Salesforce Subscription Management Guide:

“Cancellations are effective on or after the date they are performed. Backdating cancellations before the current amendment date is not supported.”
