from what i have found. $Balance is the amount unpaid by that customer. so the total outstanding by that customer.
$Amount is the invoice amount so the total invoice.
As for $Total i have not found that in all my JSON mapping.
Is there any variable for the original invoice amount (ie. does not include fees added later)? For example, let’s say an invoice was issued for $100, then a $5 late payment fee was added later. Is there a way to show this in an email template like so:
Invoice Number: 001
Invoice Amount: $100
Due Date: Jan 1, 2019
Balance Due: $105
Right now the totals are all updated with the new amount due, so none reflect the original invoice amount.
