I need targeted enhancements across our Odoo 18 environment, touching Sales, Inventory and Accounting. Sales • Custom reports that present order margins and salesperson performance • Workflow modifications to reflect a two-step approval chain • New fields and forms on leads, quotations and orders Inventory • Custom stock valuation and movement reports • Workflow tweaks for intermediate quality checks • Extra fields on products and pickings Accounting The accounting flows must absorb the new data points introduced above, so journal entries and analytic tags stay consistent. Minor form additions and report tweaks will complete the alignment. All work should be delivered as clean, upgrade-safe custom modules built with Python, XML/QWeb and PostgreSQL best practices. Please commit to Git, document key models and actions, and validate everything in a staging database before final hand-off. Acceptance criteria • Added fields/forms appear and save correctly • Adjusted workflows execute end-to-end without traceback errors • Reports export flawlessly to PDF and XLS • No errors in server logs after installation
