Overview
InvoiceOps is a professional, self-hosted multi-tenant invoicing and billing SaaS application built with Next.js, React, TypeScript, Prisma, and PostgreSQL.
It is designed for freelancers, agencies, service businesses, and small teams that need a complete invoicing system with invoices, quotes, recurring billing, client management, product/service catalog, payments, expenses, reporting, and a client portal in one ready-to-install package.
The application includes a modern responsive dashboard, secure authentication, organization-based data separation, PDF invoice generation, Stripe and PayPal payment support, SMTP email delivery, backup tools, admin monitoring, setup wizard, and detailed buyer documentation.
InvoiceOps is not just a starter template. It is a complete commercial product package that can be installed on a Node.js-capable VPS, Docker environment, Railway, DigitalOcean App Platform, or Vercel with the correct PostgreSQL and storage configuration.
