Hello! a have a question. There are some situations when after invoice sent and money piad something goes wrong. This leads to changes in overall price. For example: I sent my customer an invoice with the total price 2000$ and he paid it. After this my customer tells me that delivery is his responsability, and the price is going to be 1800$ but he already paid 2000$. How can I change my invoice or somehow make a note about this overpayment in ZOHO? Maybe somehow count it in future invoices for this customer...
