Why Do Prepaid Cards Fail in Recurring Billing?

Prepaid cards can present unique challenges for recurring billing due to several specific factors. These often vary by the card's issuing bank or brand, making a blanket configuration difficult. Here are the primary reasons you might see prepaid card payment failures:

Initial Authorizations Don't Guarantee Funds

When an initial card authorization is performed (e.g., for a trial sign-up that doesn't process a full amount), it typically validates for $0 or $1. This confirms the card number is valid but doesn't check for sufficient funds. This means a prepaid card with a low or zero balance can be approved at signup, only to decline later when a full payment is attempted.

"Recurring" Transaction Flags Can Lead to Rejection

When Recurly submits a signup transaction to your payment gateway, it's sent with an "Initial" flag. This flag triggers a more thorough authorization, including checks for CVV and AVS. However, subsequent recurring transactions are submitted with a "Recurring" flag. Some prepaid cards are configured by their issuer to reject transactions specifically marked as "Recurring," causing the initial signup to succeed but subsequent renewal payments to fail. Certain corporate cards can also exhibit this behavior.

Insufficient Funds is the Most Common Reason

The most frequent cause of prepaid card declines in a recurring environment is insufficient funds. Unlike traditional cards that are often linked to bank accounts and frequently recharged, prepaid cards typically hold a fixed, finite balance and are less commonly reloaded. This makes them highly susceptible to declines once the initial balance is depleted.

Strategies to Improve Prepaid Card Success

While these challenges exist, you can implement strategies to improve prepaid card success rates:

• Elevate Initial Authorizations: Consider performing a larger authorization at signup (e.g., the full subscription amount) and then immediately voiding it. This helps confirm a substantial balance is present at the outset, reducing declines from low funds and protecting against some fraudulent signups.

• Staged Optimization for Renewal Rates:

  • If you're using $0 authorizations (ZDAs), try moving to $1 authorizations first. Monitor renewal rates for 2-4 weeks to assess the impact.

  • If further improvement is needed, consider charging (and then voiding) the full transaction amount during signup. Benchmark these changes over 2-4 weeks to properly evaluate their effect.

• Leverage Gateway Fraud Controls: Many payment gateways offer advanced fraud controls that allow merchants to block cards by type. If prepaid cards are a persistent issue, check with your gateway provider about this functionality.
