I have edited my invoice template via web browsers but it is not pulling through on the app and reflecting my edits , specifically I added my banking details

Hi @gifts-millennium, I'll help share details about your invoice template.

As of the moment, there isn't an option to select a template while creating invoices via the QuickBooks Online mobile app. Even if you've customized a template using a browser, invoices created via the mobile app will always use the standard or default template.

While the option is currently unavailable, you can send this request directly to our developers via feedback. I'll show you how.

1. Open the QBO app on your mobile device.
2. Go to Menu.
3. Under ALL, select Feedback.
4. Enter a few words describing how you wanted to have the option to choose an invoice template while using the mobile app.
5. Select Send feedback.
6. Click Got it.

I'm adding this reference so you're able to track the status of your request as well as the latest updates from our developer team: Customer Feedback for QuickBooks Online.

It'll always be my pleasure to help if you've got other questions besides this one. Use the Reply button and leave your comment below so that I can assist you further. Take care always!
