Hi Aqualine2,

Thanks for posting in the Community!

You're on the right path with the steps you've provided when processing batch payments. Good find with the bank account used when processing the Batch payment. That is what I'm thinking as well while reading your post. We'll have to make sure to select the correct bank account set up to pay the batch payment.

If you have created the Bill payment and missed creating batch payment, you will  have to undo the bill payment.  You can check this link to learn more about How to enable batch payments or create ABA Files.

Please let me know if you have any additional questions. I'm always willing to assist.
