Good afternoon, @labels1.
Welcome back to the Community! I'd be more than happy to give you some clarification on the difference between ACH and Direct Deposit.
ACH payments can include both a credit (adding funds) and debit (withdrawing funds). Direct deposits are only credit payments, in which money is credited to another account through ACH.
The Bill Pay powered by Melio integration was discontinued on May 20, 2024, businesses previously using Bill Pay powered by Melio are able to apply for one of three QuickBooks Bill Pay plans: Basic, Premium or Elite in QuickBooks Online.
With this being said, we recommend reviewing each of the guides/links below to get more information on Melio and QB direct deposit for a vendor to see which one would be the best fit for you and your business:
If you have any other questions, I'm only a post away. I'll be waiting for your response!
