Hello there, @userkmcleaners. I'm here to share some information on managing your bank transactions.
Once you receive bank deposits from your customer, you need to link them to an invoice. Doing this keeps your records accurate and helps avoid errors when it's time to reconcile your accounts. But before doing this, there are things that you need to verify, and these are the following:
Make sure you haven’t entered and linked the payment to the invoice.
In addition, the system will not delete data on your bank statement as QuickBooks just matched the downloaded transaction with the one you already entered. It links them together, so you don't get duplicates.
