Odoo Manufacturing software provides BOM management supporting multi-level structures, multiple product variants, and engineering change orders with version control capabilities. The Odoo MRP system allows defining operations sequences, work centers, and scrap rates while calculating raw material requirements and associated costs. Users can import BOMs from spreadsheets, duplicate existing structures for efficiency, and set effective date ranges for planned modifications. Phantom BOM functionality simplifies manufacturing process representation for subassemblies consumed during production.
