PHP Payment & Billing Scripts — Gateways, Invoices, Subscriptions
Turn your project into a revenue-generating product without rebuilding payments from scratch. These PHP payment & billing scripts wrap popular gateways (commonly Stripe and PayPal) and give you the pieces teams reach for first: hosted or embedded checkouts, one-time payments and subscriptions, invoices/credit notes, coupons, taxes/VAT, refunds and webhooks. You get an admin panel for plans, customers and transactions, branded email templates and exportable reports—so you can launch quickly and keep finance tidy.
What you typically get
- Gateway integration (Stripe/PayPal) with keys, webhooks and test/sandbox modes
- Charge flows: one-time payments, subscriptions, trials, proration and upgrades/downgrades
- Invoices, credit notes, receipts, PDF exports and email notifications
- Discounts: coupons, promo codes, gift cards and introductory pricing
- Taxes/VAT rules, customer addresses and invoice numbering sequences
- Customer portal: update cards, download invoices, manage plans and cancellations
- Dunning: failed-payment retries, reminders and card-update links
- Reporting: revenue, MRR, churn, refunds and payout summaries
Choosing the right script
- Business model: one-off purchases, subscriptions, usage-based billing or mixed?
- Compliance: 3D Secure/SCA support, PCI considerations (use hosted fields/links when possible), GDPR data handling.
- Taxes: out-of-the-box VAT/TAX rules vs. manual rates; country/state logic; reverse charge notes.
- International: multi-currency, localized invoices and right-to-left email templates.
- Ops & scale: queues/cron for webhooks and retries, caching (OPcache/Redis), clean logs and idempotency keys.
- Extensibility: REST endpoints, webhooks, events/hooks for your app logic, and clear folder structure.

Security & compliance essentials
Use HTTPS everywhere, set strict CSP and security headers, and prefer hosted inputs/payment links to minimize PCI scope. Enforce SCA (3D Secure) where required, sign and verify webhooks, and audit refunds/credits with role-based permissions. Store only what you must; tokenize cards via the gateway and rotate API keys regularly.
