4. How to Submit GRN for Bill
To create the bill against the GRN, click on the option given in the action button, i.e., Create Bill.

Users can use this option until they want to submit a bill against this purchase order. Once you click on submit bill, the system automatically submits the bill to the supplier account. You can check that new bills will be displayed in the “bills section” as well as in the specific “supplier account” too.

There is a way to generate GRN through the purchase order section.
