Invoicing with precision payment follow up?

The methodology we use is to insist and follow up

Invoicing with precision payment follow up to increase collections up to 16%  

This is the way we do it: The payment date is reminded with an email a few days before the due date. We also send a reminder of the due date of the invoice, then a few days later we connect to your own system to check if it is still marked as not paid in your database, then an email or SMS is automatically sent, remembering to make the payment. This as I said improves the collection rate up to 16% and lower cost as you would not depend on the call center anymore. Also clients are actually happy that they are reminded and handed an easy and quick way to pay.
