How do I delete an invoice, and apply the payment to a sales receipt?

Thanks - but then how do I deal with the "unapplied payment" categorization on the sales receipt?

I'd like to make sure that the payment is applied to the receipt and I can't figure out how to do that, otherwise it's just a random payment without any association to it, although it does say who it's from.

Thanks for getting back to us, johnnybregar.

QuickBooks Online is dependent on the data shared with us by PayPal. You may want to check the mapping of your PayPal transactions. See article for more information: Modify settings for Sync with PayPal.

Once updated, the transactions will be imported back to QuickBooks Online using the new mapping. This time, you can match the payment to the bank transaction.

Here's an article for more information: Add and Match Downloaded Banking Transactions.

This bit us too; on all our PayPal payments, I went back and copied the transaction information from the sync'd item and then deleted the sales receipt and re-logged the transaction as a payment on an invoice with all the transaction information from the deleted transaction so I could record the payment. An annoying work around but effective none-the-less.
