Focus on the carrying invoice
The Carrying invoice is the oldest unpaid invoice of your customer, when the reminder is triggered. You can benefit from multiple tags based on this reference to focus your reminders on it. This is the reference (and tags) we’ll offer in our default templates when creating a workflow or a new action.
Due vs Overdue
When using due/overdue tags in your reminders, be mindful of when this reminder is meant to be triggered. Any reminders scheduled before the due date must absolutely not use Overdue tags (invoice list or amount). As this reminder is meant to be triggered only if the customer has no overdue invoices, these tags would render blank or show a 0.00 amount. Before the due date…
- Customer due amount
- Customer outstanding amount
- Due invoice number list
- Carrying invoice number
- Carrying invoice outstanding amount
- Any other carrying invoice tags
- Customer outstanding amount
- Outstanding invoice number list
- Customer overdue amount
- Carrying invoice days since due date or Carrying invoice due date
Highlight your customer’s entire balance
If you want your collection reminders to show the outstanding balance and all open references, then we’d advise using the following tags:- Customer outstanding amount
- Customer overdue amount
- Overdue invoice number list
- Due invoice number list


Highlight your customer’s Overdue balance
Then, only use the following tags, and attachment option:- Customer overdue amount
- Overdue invoice number list
