Hello and welcome to the Community, mgm1323.
It would be my pleasure to help you record the ACH payment for the bill in QuickBooks Online.
We can record the bill payment to an open bill by performing the normal process. However, you'll need to add a note on the Ref no. field instead of adding a number.
For more information for recording the bill payment made through ACH, you can visit the article I recommend on this:
Record a bill payment processed online, via EFT, ATM, or debit card.
Please don't hesitate to let me know if you need further assistance with the payment process. I'll be sure to get back to you.
I did the listed process but the amount still remain in Account Payable account after post payment? What is the process to remove it from A/P and posted as expense etc.?
Good to see you here, mauser3.
When you processed a bill payment, the transaction will not be removed from A/P account. Instead, it will only decrease the A/P balance.
To make sure that you successfully processed the payment:
You can also open your A/P account and search the bill. From the DUE DATE column, make sure it shows Paid.
You can use the same article about recording a bill payment for your future reference.
For other concerns, please reply again to this thread.
