Why does my invoice only dont have option to be paid? Only save or print

Hi, roi. It's my pleasure to help you view the option where you can mark your invoices as paid.

This option will only appear when you already save your invoices. I'm here to show you how to view this.

For Old Layout

1. Go to the + New on your left navigation panel.
2. Select Invoice under CUSTOMERS.
3. Add the necessary details. 
4. Hit Save.
5. In your upper right corner, you'll see the balance due. Click the Receive payment button below the amount so it will route you to its page.

For New Layout

1. Head to + New, then select Invoices. 
2. Add important information.
3. Click Save.
4. Go to the Review and send dropdown, then select Receive payment.
