How can I change my invoice number on iPhone app !

Welcome to the Community space, @bonowoods-yahoo-.

You'll have to open the existing invoice and the change number from there. Then, QuickBooks will follow the number sequence that you've set on your invoice.

To edit the invoice number, here's how:

1. Go to the Invoice menu.
2. Select the transaction or customer's name.
3. Open the invoice and click Edit.
4. Change the invoice number, then tap Save.

You can also edit your invoice number through a web browser. Just make sure to turn on the Customer transaction button before changing the invoice number. For more details see this article: How to change an invoice number. It also contains a video tutorial for visual reference.

Also, you can change your invoice template and other sales forms while you're on the go. Just click these articles on how to personalise them:
