Being able to customize your invoices by adding important information beyond the billed amount is value-add to your subscribers to keep them in the know of what they’re consuming. On top of being able to display unit price, quantities, date ranges, subtotals and $0 product line items, you now have the option to display an ‘Other’ balance.
This option will display the total due on any existing payable invoices for said subscription at the point the new invoice was issued. In addition, there will also be a list of all invoices which were outstanding and the individual amounts that were due at the time of issuance. So for instance, if your customer did not pay their January bill, and the February invoice has been issued, the February invoice will show the past January balance as past due.
