Create a location for each Project that is of type Inventory Loss with a Stock Valuation Account (Incoming) account configured to offset the value of inventory "lost" during the move to this location.

Move your products to this location instead of the regular Stock location when you process the Receipt (or after via an Internal Transfer if you forget).

Consult your Bookkeeper or Accountant ​to understand which account to use and inform them they will need to move this amount out as it represents additional project costs.
