Let's assume we have a Goods Issue Note and we only want to invoice a part of it. Below we can see that the Goods Issue Note includes 2 kg of apples and 2 kg of pears. The customer is paying only for 1 kg of apples.


Later, we want to generate an invoice for the remaining items. When we're on the same Goods Issue Note and press Generate VI again, we’ll see a message asking whether to open the existing invoice or, by clicking Generate to generate a new invoice for the uninvoiced items.

A new document is created with the missing 1 kg of apples and 2 kg of pears.

In Links of the Goods Issue Note, we can see two linked invoices.

If we want to generate an invoice for all uninvoiced items from multiple Goods Issue Notes issued for a customer over a given period, we can do this in batch mode. Go to the Invoice wizard.
Select "Document generated based on many issues" and check "Generate from all non-invoiced items."
Select the customer and click +We can see that the selected customer has one Goods Issue Note with remaining items.

Proceed to the next step clicking OK. The program sums up the quantities from those all Goods Issue Notes and creates one invoice containing only the uninvoiced items.
