Connectwise Late Fees Service

Connectwise Automated Late Fee Service

Finally!  A system that automatically generates late fee invoices and/or agreement additions for past due customers. Completely automated and customizable.

We guarantee you will see a dramatic improvement in payment receipts after activating this application. We originally wrote this application for in-house use nearly 3 years ago.  Immediately our slow paying customers started magically paying on time!!  And we are hearing the same responses from other MSPs using this software.


Every 24 hours (user adjustable time) the service will search for all past due invoices in your Connectwise system and systematically create Miscellaneous late fee invoices for non-agreement past due invoices, and agreement additions for past due agreement invoices.  This is user selectable, you can choose to only create miscellaneous invoices for all past due balances and not create agreement additions during configuration.

  • The system runs as a service on any machine at your location – it is recommended to install it on a server or other machine that does not get powered off. Minimal resources required - the entire nightly process takes a few minutes.
  • The system can send an email “digest” each day that tells you what late fee invoices were created.
  • All data required for the service is actually stored in your Connectwise system, no data of any kind (except the log) is stored on the machine running the service.  This allows you to move the service to a difference machine if needed without losing any integrity of data or historical data required by the service.
  • A new configuration type “Late Fee Service Info” is created by the setup application in your Connectwise system, the service then creates and uses these configurations under the past due customer’s accounts to store past due invoices and other data required by the service.
