An Odoo module that values stock per warehouse instead of once per company. Standard Odoo keeps one average cost per product, so goods bought at different prices in different warehouses all end up at the same blended cost. With this module, each warehouse keeps its own cost.

Features

  • A separate cost for each product and warehouse, updated with AVCO on every receipt
  • A history of every cost change: old and new cost, difference, user and date
  • Valuation layers carry their warehouse, so deliveries are valued at their own warehouse’s cost
  • Stock lists show Unit Value and Value per warehouse
  • Landed costs raise only the receiving warehouse’s cost, prorated to the stock that remains
  • The revaluation wizard works on one warehouse at a time
  • Transfers between warehouses (EXO → EXI) move the value along with the goods
  • Covered by 16 automated tests, run by GitHub Actions on every push and before every release
