Research consistently shows that roughly 50% of B2B invoices are paid late, even among companies with enterprise ERP systems in place. If you're using NetSuite, SAP, or Dynamics and still fighting overdue invoices every month, you're not alone — and it's not a configuration problem. It's a design problem.
ERPs were built to record financial transactions, not to drive collections. They know what you're owed. They don't know how to get you paid.
ERPs generate invoices and track status. They don't automatically send payment reminders, escalate overdue accounts, or adapt messaging to individual customers. That work still falls on your team.
A large percentage of invoices go overdue simply because they landed in the wrong inbox. ERPs store one billing contact per customer and rarely prompt you to update it. Courtasy tracks contact accuracy and flags delivery issues automatically.
Even when your invoice is correct and on time, it may sit in an AP queue waiting for approval. A well-timed follow-up to the right finance contact can unblock these in minutes. ERPs have no mechanism for this.
When an invoice hits 30 days overdue, most teams send another version of the same email. A proper escalation workflow — stepping up in urgency, contact level, and channel — dramatically improves collection rates. This requires logic ERPs don't provide.
ERPs show you what's already overdue. AR automation prevents invoices from becoming overdue in the first place. The difference is proactive reminders before the due date, not just reports after the fact.
The answer isn't replacing your ERP. It's adding a layer specifically designed for collections. Courtasy connects to your ERP or accounting tool, pulls invoice and customer data, and handles the entire follow-up process automatically — from pre-due reminders through final escalation.
Teams using AR automation alongside their ERP reduce overdue invoices by an average of 40% and cut DSO by 18% in the first 90 days.
