Is there a way to link bills that are due to the bill pay service in the iPhone app for QuickBooks online?

Let me help share information about creating bill payments using the mobile app, @hawaiiarchitect.

As of the moment, there isn't an integrated way to pay your bills that are due directly from the mobile app for iOS devices. It's best to manually send your bill payments by logging in to any of the browsers that work well with QuickBooks Online.

While the option is not yet available, I'd recommend letting our product developers know about your request by sending feedback. I'll show you how.

1. Go to the Gear icon.
2. Select Feedback.
3. Enter a few words describing how you wanted to pay bills from the mobile application.
4. Click Next.

I'm adding this reference so you're able to track the status of your request: Customer Feedback for QuickBooks Online.

It'll always be my pleasure to help if you have any other questions besides this bill payment concern. Please let me know by clicking the Reply button and leaving a comment below. Have a good one!

As a workaround, open a separate Melio account for free to integrate with your QBO.

At this time there is not a stand alone mobile app for either iOS or Android devices, but Melio works great on the mobile device of your choice. On your phone, launch your browser and head to their website address to pay your bills.
