Subscription billing apps

Subscription billing software manages recurring revenue from sign-up to payout. It starts with you defining products, plans, add-ons, free trials, discounts, and billing cycles. You set rules for taxes, proration, and when to charge or invoice.

Customers subscribe through hosted checkout pages or your own app. Payment details flow through a gateway or a merchant-of-record service. Tools like Stripe process cards and wallets, while platforms such as Lemon Squeezy or Paddle can act as merchant of record, handling payments, tax, and compliance on your behalf.

The system generates invoices, charges customers on schedule, and handles renewals, upgrades, downgrades, and cancellations. It applies coupons, calculates tax, and prorates changes mid-cycle. If a payment fails, dunning kicks in with retries and emails to recover revenue.

Behind the scenes, webhooks and APIs sync events back to your app. You can provision features on successful payment, or pause access on delinquency. Dashboards track monthly recurring revenue, churn, and cohort trends. Exports and integrations feed accounting, analytics, and support tools.

Refunds, charge reversals, and disputes are managed through the same workflow. When required, the platform remits taxes to authorities if operating as merchant of record. Otherwise it prepares detailed reports so your finance team can file accurately.
