Retry Logic

What does "retry logic" mean?

Retry logic is the automated mechanism that re-attempts a failed subscription payment after the initial charge is declined. Every subscription billing system includes some form of retry logic, but the sophistication varies dramatically — from basic fixed-interval schedules to AI-driven smart retry engines.

Basic vs. smart retry logic

Basic retry logic follows a predetermined schedule: for example, retry 1 day later, then 3 days later, then 7 days later. This approach treats every decline identically regardless of the reason, the issuer, or the time of failure.

Smart retry logic analyzes the decline code, issuer behavior, transaction history, and timing patterns to determine the optimal retry window for each individual payment. A generic decline at midnight might be retried mid-morning. An insufficient funds decline might be retried on the next expected payday.

Why retry logic matters

Retry logic is the first line of defense against involuntary churn. It recovers payments silently — the customer never knows their payment failed. The better your retry logic, the fewer customers you need to contact through dunning and the fewer you lose to canceled subscriptions.

FlyCode replaces basic retry schedules with an AI-powered retry engine that uses Visa and Mastercard network data to optimize timing for each transaction, significantly outperforming fixed-schedule approaches.
