Odoo treats Packages and Packaging as optional: even with default packaging defined, when packing, the system requires manual input and doesn’t auto-split quantities based on packaging rules .

 Workarounds & Solutions:

• Manual Splitting:
  • Use multiple Put in Pack operations, manually splitting into the required quantities.
  • Impractical for large volumes (e.g., splitting 6,000 units requires repeating steps thousands of times) .
• Use OCA Module ("Stock Packaging Usability"):
  • Lets users choose the packaging type on-the-fly during picking.
  • Improves UX by prompting for packaging on Put in Pack actions 
• Purchase Extension for Auto-Add Packaging:
  • Module “Purchase Product Packaging Container Deposit” automatically calculates the number of required packages (examples: pack of 12, pack of 24, pallet of 240) and adds needed packaging lines in purchase orders 
  • Useful for automating packaging or deposit charges.
• Post-Production Packaging Workflow:
  • A common practice is to complete manufacturing as unpackaged goods, then:
    • Add a dedicated “Pack” operation after production.
    • Manually create packages from output quantities.
    • Optionally assign packages when delivering to customers
