A failed renewal rarely means a customer wants to leave. Most of the time the card was replaced, the bank was cautious, or the account was short for a day. Treat those failures like cancellations and you lose customers who never meant to go.
Why renewals fail
Renewals fail for two broad reasons. Hard declines, such as a closed account or a card reported stolen, will not succeed on a retry. Soft declines, such as insufficient funds or a temporary issuer block, often succeed later. The first job is telling them apart.
Reading the decline
Every decline arrives with a reason code from the issuer. PayServ combines that code with the card type, issuer, country and the customer's own payment history to estimate how likely a retry is to succeed, and when.

decline_code: "insufficient_funds"
retry_recommended: true
next_attempt: "2026-10-03T09:00:00-05:00"Timing the retry
Retrying immediately usually fails again and can make an issuer more cautious. Retrying on a fixed schedule ignores everything you know about the customer. A better approach waits for the moment the payment is most likely to clear, such as the morning after a typical payday for that customer's bank.
When to ask the customer
Some failures need the customer. When a card has expired or been replaced, PayServ sends a short, branded message with a link to update the payment method, and pauses retries until they do.
