ezyCollect was designed to chase debtors based on the oldest overdue invoice date. 

The communication workflow and its follow ups , follows this design. 

Example:

Client :
Invoice 1 due date - August 15, 2018  - This is the oldest overdue invoice date and basis of ezyCollect's follow up email (first follow up email)
Invoice 2 due date - August 30, 2018
Invoice 3 due date - September 15, 2018

Note: even if the system chases based on the oldest overdue invoice, ezyCollect consolidates overdue invoices in one email reminder which allows you to chase all overdue invoices.
