Here is a guide on how to create a consignment invoice from an order.
First, you need to create a consignment sales order and have it fulfilled with the customer. Once it's time for the customer to send back your items, you must find out how much they sold. Once you have this information in hand, it's time to create an invoice.
In ERP, go to Sales > Consignment Invoice Processing.
Click Add.
Click Load Sales Order.
Click the order you wish to load.
Your order has been loaded into this new invoice.
In the Lines tab, you'll see the amounts of each item that were originally ordered (Order UT and Order tabs), which are also reflected in the B.O. (Back Order) column. This means that, if no items are sold, that amount will be sent back to you.
Enter the quantity of each item sold in the Ship UT column. You will notice the values in the Ship and B.O. columns automatically adjust.
When you're done, click Save.
Click Yes.
Your invoice was successfully added.
This invoice will update the original order.
Note: You can create multiple invoices associated with a single consignment S/O.
Aside from these small differences, the invoices are pretty much the same as traditional sales invoices. Check out this guide on invoice management. The payment process works exactly the same as well.
