BillingPro Suite

A full-stack subscription billing engine built on Express 5 and better-sqlite3 — real invoices, real automation, not a spreadsheet. Stripe Checkout and Subscriptions integrate via webhooks for live payment status, PDFKit generates polished invoice PDFs automatically, and a node-cron daily job runs recurring billing with a 3/7/14/30-day dunning escalation for failed payments. Customers get a token-scoped self-service portal to manage their own billing, while bcrypt password hashing, TOTP two-factor authentication, and IP rate limiting keep admin access locked down. Multi-currency support refreshes exchange rates daily, so pricing stays accurate across markets. ↓ Download Sales Deck
