Question
How can I partially refund a customer on an already paid and closed invoice?
Our clients pay their bundled products at the beginning of their stay fully (surf camps, including different items like 5 x surf courses accommodation etc). At the end sometimes the items in their bundles change and they need to be refunded because they couldn't go surfing on one day (so he only does 4 days and i am therefore deleting that item from his bundle). The invoice sais that everything is paid, however the clients balance is negative. I can't send this invoice to the customer because it clearly states a wrong number of payment received. I can't make a credit note because the invoice is already open. I also can't just add a refund because it is not linked to his invoice and the invoice still states the wrong numbers. How can I partially refund items and add different ones instead from an alreday paid invoice? Thank you
