Why the timing of payment retries determines whether failed charges are recovered

Each failed payment has a recovery window whose length depends on the cause of the failure. Insufficient funds can remain recoverable for weeks because balances refill on regular cycles, so retries timed to those cycles tend to succeed. Expired cards are different, since the opportunity fades once the customer decides not to bother updating details, which means outreach must happen quickly. Because retry attempts are limited, their timing matters more than their number, and spacing them across the days a failure type typically resolves works better than clustering them early. The approach also includes backfilling failures from the ninety days before a tool is connected, and it stops retrying once a window has closed.
