eCommerce Business Management Software Source Code for $149ERP Software

Most businesses spend months evaluating ERP systems that cost tens of thousands of dollars per year, only to end up locked into vendor contracts, restricted customization, and monthly invoices that never stop. Extreme ERP breaks that model entirely. For a single one-time payment of $149, you receive the complete Visual Studio source code, SQL Server database scripts, 160+ functional screens, 150+ Crystal Reports, and full deployment documentation for a production-grade, .NET ERP and eCommerce Business Management Software — built on Microsoft’s proven enterprise stack and now distributed globally by Alwajeez Tech, headquartered in Jeddah, Saudi Arabia.

This is a battle-tested codebase with real businesses running on it. Alwajeez Tech has taken that proven foundation and made it available to developers, SaaS entrepreneurs, and SMB owners worldwide — with full source code ownership, zero recurring fees, and a cloud-ready, multi-tenant architecture that is ready to deploy on any Windows Server or cloud VPS today. Whether you need a self-hosted ERP for your own operations or a launchpad for a client-facing SaaS ERP solution, Extreme ERP gives you complete control from day one. The codebase is structured for straightforward modification with AI coding agents — Claude Code, Cursor, GitHub Copilot, and Gemini all work naturally with its clean ASP.NET C# architecture. No vendor lock-in. No permission requests. No monthly surprises.
