Thank you for checking with us, @lmulkey4007@yaho. I'll provide insight into matching invoice payments from banking to invoices in QuickBooks Online (QBO).
When your customer pays their invoice online, QuickBooks automatically process these payments. All you have to do is to review and match them in your banking feeds. You'll see a match found banner under the Category or Match column.
You'll have to use Find Match to look for the correct payments for the invoice transactions. The best option would be to adjust the invoice in QBO so it matches what came from the bank.
Go to Bookkeeping, then Transactions, and select Banktransactions.
select the bank and look for the deposit in For Review.
Click the deposit and select Find Match.
Filter the Date range that includes the date when the invoice payment was created.
