Posting payment to Invoice

Hello ME-, 

Welcome to the Community page, 

Did you actually make two payments in real life, or did you just enter it twice in Quickbooks in error. Is this a customer paying you twice, or did you pay an expense twice?  

HI

Supplier was paid twice for the same invoice.  We paid them not just a QB entry error.  We made a payment in Aug and again in Sept.  We contacted the supplier who agreed to send us back the overpayment, however we had another invoice due since then so they kept the amount of this and returned us the difference.

What I have done but not sure it correct.  I went in and made the full payment against the now due invoice which left an overpayment on that invoice.  I then made a deposit to record the refund and used this deposit to clear the overpaymet on the customers account

Hello ME- thanks for coming back to us, so if the over-payment is the same as the difference the supplier has sent back, you can create a bank deposit from the supplier with the account set as the Accounts Payable Account then you need to click Pay Bills and choose this amount and assign the credit to it to clear it off. In Pay Bills you will see the deposit, tick that and in the credit section should be the over-payment, tick that too and then its all recorded in your quickbooks for you.
