How to apply a credit note to invoice with partial amount

Dear Community,

I have the following particular situation in which I sent a customer’s invoice for 3 products by 200 each for Amount on the invoice a $600 but customer returned 1 product. now i need to create a credit note applied to invoice for 200.

How can I accomplish this in Tryton ?

Hi José,

if you are using the sale module you should use the wizard “Return Sale” on the sale you used to send the products to the customer. It will create a new sale with negative values. If you confirm this sale it will create a return shipment for you and a credit note.

Hi @timitos but this wizard create a complete return and complete credit note. i need a partial credit note …

The return sale can still be edited before confirmation.
