Hi there, Liuber. Let me share information regarding the invoice and payment details in QuickBooks Online.
When utilizing QuickBooks Online (QBO), it's important to ensure that when you receive payment for an invoice, it comes from the customer to whom the invoice was originally designated. This helps prevent the creation of duplicate transactions and maintains the organization of your financial records within QBO.
Moreover, you can make partial payments by manually overriding the amount to pay another invoice and pay from there. You will open invoice emails and select Pay Now. This then will create a different invoice from the original one.
Furthermore, you can refer to these helpful materials when receiving and recording invoice payments on QuickBooks Online:
Additionally, if you have customers who deposited their payments through the bank, learn how to link them through this article: Link a bank deposit to an invoice in QuickBooks Online.
Return to this thread if you have further questions about the payment process in an invoice in QBO, Liuber. I'll be here to answer them as soon as I get your reply. Keep safe!
