I need an experienced Python-based Odoo developer to fine-tune the built-in Sales, Inventory, and Accounting modules so they match our company’s specific workflows. The core job is to work inside our existing Odoo instance—no brand-new modules or external integrations—just thoughtful refactoring and extension of what is already there. What I need you to do • Analyse our current configuration and pinpoint where standard Odoo behaviour falls short. • Rewrite or extend models, views, and business logic in Python, ensuring changes remain upgrade-safe. • Adjust security rules, automated actions, and reports so users in each department see only what they need. • Provide clear, commented code and a short change log so our in-house admin can follow future upgrades. Acceptance criteria – Customisations compile without errors on Odoo’s latest 16 .x community build. – Updated features demonstrate the requested behaviour across Sales, Inventory, and Accounting workflows in a staging environment. – All modified files are delivered through Git with commit messages that describe the purpose of each change. If you work comfortably with Odoo’s ORM, QWeb, and standard testing tools, I’d like to hear how quickly you can start and a rough estimate of the hours you’ll need.
