If I am allowed to create 3 custom invoice fields, why does the third on not show up in the fillable form in the mobile app.

I'll go over some details about the fillable form not showing when creating invoices using the QuickBooks mobile app, jeffatjoneselect.

The option to use the fillable form for your custom fields when creating invoices through the QuickBooks Online (QBO) mobile app is unavailable. We can utilize the fillable form by logging in to your account through a web browser.

I can see having this option would benefit you and your company. I recommend sending your feedback to our Product Development Team, so they can look at it and consider implementing it in the future.

Here's how you can submit feature requests using your QBO mobile app:

For Android devices:

1. Select the Menu button.
2. Tap the Gear icon.
3. Click on the vertical ellipsis ⋮ in the upper-right corner.
4. Choose Feedback
5. Type in your feedback and product suggestions.
6. Hit Send Feedback.

For iOS devices:

1. Go to the Menu ☰ icon, then select Help & Feedback.
2. Choose App Feedback.
3. Type in your feedback and product suggestions.

You may also send feedback through a web browser by clicking this link: How do I submit feedback? On the other hand, visit our Feedback forum page to see a list of other QuickBooks users who suggested this feature, as well as the recent updates in QuickBooks.

For now, you can use the web browser for your fillable forms when creating invoices. For more details, open this link: Create and edit custom fields in QuickBooks Online Advanced.

Additionally, I'll be sharing these resources that will guide you in personalizing sales forms and using enhanced custom fields in your reports:

If you have any suggestions or additional concerns with fillable forms, please let me know. I'm always here to lend a hand. Take good care.
