Invoice SaaS Generator
Multi-tenant SaaS for invoice generation with Razorpay subscription billing
Built as a full multi-tenant SaaS — each account gets isolated data, custom invoice templates, and the ability to email invoices directly to clients as PDF attachments. Razorpay handles subscription billing; webhooks keep subscription status in sync in real-time with retry logic for failed deliveries. Owner/member RBAC via Clerk Auth means business owners can invite team members with restricted access. PDF export uses a server-rendered template approach so output is consistent across browsers and email clients.
