Small Business Management ERP Software Source CodeERP Software

The only ERP source code your business will ever need

Most small businesses make one of two costly mistakes: they either pay a developer $80,000 to build something from scratch, or they lock themselves into a SaaS subscription that bleeds $1,500 every single month — forever. There is a smarter path. XERPz is a proven, production-grade ERP source code that has been refined through years of real-world deployment, and it is now available to global buyers through Alwajeez Tech — a Saudi-based technology company with deep roots in enterprise software consulting.

This is not a demo project or a tutorial codebase. XERPz is a complete .NET ERP covering multi-branch accounting, inventory, HR, payroll, sales, purchasing, warehouse management, and many other multi-branch operations — all from a single installation. The architecture is SaaS-ready, with Project-based multi-tenant data separation so you can onboard dozens of branch or clients on one server. Security is multi-layered: form-level and menu-level access control means every user sees exactly what they should see — nothing more.

You own the code. You own the database. You deploy it on your own Windows Server or any cloud VPS. No vendor. No lock-in. No monthly invoice. And because XERPz is built on mainstream ASP.NET / SQL Server technology, it is fully compatible with AI coding assistants — modify it confidently using Claude Code, Cursor, GitHub Copilot, Codex or Gemini. This is the self-hosted ERP solution that gives you the power of enterprise software and the freedom of complete ownership.
