I’ve invoiced a purchase order that has already been receipted. Why don’t any extra lines I added to the invoice appear in stock?

Answer:
When a purchase order has already been receipted, the system treats the receipt as the official record of what was received into stock. Any additional lines added later at the invoicing stage are considered financial adjustments only and do not automatically update inventory levels.
If extra items are added to the invoice that were not part of the original receipt, you’ll need to create a separate receipt to bring those items into stock. This ensures that stock records remain accurate and that inventory movements are properly tracked.

Note: If you receipt and invoice the purchase order in the same step, all lines on the invoice are receipted into stock.
