Open Source ERP for Manufacturing: Who Owns Your MRP Logic?

Disclosure: del.ai sells NetSuite-to-Odoo migrations and has a direct commercial interest in this argument. Treat every claim below as something to verify on a call, not take on faith.

If you run finance at a discrete manufacturer on NetSuite, you already know manufacturing capability didn't come with the base license. Bills of materials, routings, and work orders shipped as a separate priced layer. Every production-planning feature you add next means another module conversation. Open source ERP for manufacturing flips that structure. Instead of renting MRP logic module by module, the manufacturer owns the code that runs it. The company can extend that code as production needs change, instead of waiting on a vendor's release calendar.
