I don't want to show our phone number on invoice, How can I do ?

There's two ways to do it, Christina.

If you're using the new invoice interface, here's how we can remove your phone number from showing on the invoices:

1. In the invoice page, click on Manage.
2. Select Design.
3. Choose Standard and click on Manage.
4. Under the Action column, click on Edit.
5. Select Content and click the invoice.
6. Uncheck the box for Phone.

You can refer to the screenshots below:

However, if you're using the old interface, here's how:

1. In the invoice page, click on the gear icon.
2. Click on Change what your customer see.
3. Select Content and click on the invoice.
4. Uncheck the box for Phone.
