You can create Invoices on Android with just a few quick steps:
- Once logged into your account, tap on Invoices at the bottom
- Tap on the green + circle
- Create your Invoice as usual with a Client, date of issue, due date, description, line entries, etc
- When you're done, tap on Save at the top right corner
- Feel free to tap on the Paper Plane symbol (in top right corner) to send the Invoice by email, or you can hit the Arrow symbol (top left corner) to return to the Invoices page. Your created Invoice will be saved as a draft.
