Whats the Easy Map field for the full amount and percentage to be shown on a custom progression invoice? <?> And for the remaining balance <?> left after this invoice?

Hello, @phil35.

You can enable the Account Summary. It gives your customers a snapshot of their recent transactions. I can walk you through on how to do it.

1. Go to the Gear Icon ⚙.
2. Select Custom Form Styles.
3. Locate the invoice template you want to use.
4. From the Actions column, click Edit ✎. 
5. Choose the Content tab.
6. In the form preview, select the body section and then Edit ✎.
7. Mark the show on invoice tick box. 
8. Select Done.
