How can i match payment to invoices if the vat for one invoice has been added to another payment? Is there a way to combine payments and invoices so they total equally?

I'm here to help share how you can match the payment to the corresponding invoice, @plumplee-aol-com.

As of the moment, there isn't an integrated way to combine payments and invoices from a downloaded transaction. Since you can only match a downloaded transaction to an existing entry, let's undo the one that is added incorrectly.

Saying the VAT of an invoice has been added to another payment, the following steps below will show how to unlink them:

1. Go to Transactions.
2. Select Banking.
3. Under Categorised, select the VAT transaction in question.
4. Click Undo.

From here, go ahead and match the VAT and payment transactions to the existing invoices. Learn more about adding and matching your transactions with this article: Categorise and Match Online Bank Transactions in QuickBooks Online.

I'm also adding this reference that'll help you review your accounts in QuickBooks to make sure they match your bank and credit card statements: Reconcile an Account in QuickBooks Online.
