When do I capture a GL code vs and Inventory code?

If your accounting system and the specific product is set up to keep track of inventory usage, then the line items will be posted to the accounting system using the inventory item code. This process will then update the inventory item count and if the inventory item is set up correctly it will update the General Ledger (GL) with the correct transaction entries.

If your accounting system and the specific product  is not set up to keep track of inventory usage, then the line items will be posted to the accounting system using the GL code. This process will not update any inventory item counts.
