- Offer promotional incentives → Free trial credits, signup bonuses, or customer loyalty rewards.
- Enable prepaid usage models → Let customers buy credits upfront instead of committing to a fixed plan.

- Recurring charges
- If the wallet allows subscription-only credits, they will be used to pay for the customer’s recurring plan.
- If the credits are not enough, the remaining balance will be charged via the default payment method.
- Usage-based charges
- If the wallet allows usage-based credits, they will be used before any other payment method.
- If usage exceeds the available credits, standard billing rules apply (e.g., pay-per-use pricing).
- Both subscription & usage-based charges
- If the wallet allows both types of charges, credits will be used wherever applicable.
