When adding an invoice, the invoice type options are shown to be selected.

This pop up may be annoying at times.

To set the default invoice type when adding a new invoice:

1. Go to the miscellaneous screen under Setup
   
   
   
   
2. In the miscellaneous screen is the invoice default section
   
   
   
   
3. Click on the radio button of your selection: Products or Text.
   
   Mark the Ask option if you still want the windows dialog asking what type of invoice you want to create. Mark the Products option to add a Product Invoice by default or the Text option to add an invoice that is of Service type by default.
