Hello there, @danniw1979.
I am here to share some information about adding references or titles to estimates and invoices in the QuickBooks mobile app.
If you're referring to adding or editing an invoice number, it is possible to do so. However, an option to add a title to an invoice is unavailable in the QBO app.
In case you want this feature to be included in QBO, I suggest sending feedback to our product engineers. This will help our engineers understand how they can enhance existing features and create new ones to better serve our customers.
Here's how:
- Click the Three horizontal lines icon.
- Go to Help & Feedback.
- Choose App Feedback.
Moreover, I'm adding this helpful article as your reference in personalizing your invoice template in the QBO app: Customize invoices on the QuickBooks Online mobile app.
Return to this post if you have other concerns about editing your invoice in the QBO app. I'll be here to lend a hand.
