A subscription billing system with promo-code support—for example Stripe Billing or Chargebee—typically handles:
- Coupon logic: percentage/fixed discounts, trial periods, redemption limits
- Tax handling: automatic tax calculation and invoicing support
- Refund workflows: partial/full refunds, prorations, credit notes
If you want, I can recommend the best fit specifically for online learning subscriptions (e.g., one-time course sales vs recurring memberships).
