Hello, @YPM.
At this time, the feature to receive international ACH payments is unavailable in QuickBooks Online. That would be a great addition to the current features that we have, I'll take note of it.
In the meantime, I suggest you look for any third-party app that QuickBooks supports from your Apps menu. Check this article for more information: Find apps.
For now, you can visit the QuickBooks Blog to check for new updates and features that we have.
Also, here's more information on how QuickBooks Payments deposits work in QuickBooks Online: Common questions about payments deposits in QuickBooks Online.
I'm always here if you need anything else. Have a wonderful day!
