# DueTrail

> DueTrail is a B2B invoice-to-cash and collections tool for small European service companies (agencies, consultancies, IT/MSPs, bookkeepers). It turns overdue invoices into reviewable "collection cases" with a consistent reminder cadence, a customer portal with a promise-to-pay flow, and a full audit trail. Nothing emails a customer until your team approves it.

DueTrail's core idea is calm, controlled collections: get paid faster without becoming the company everyone dreads hearing from. You can explore the whole product for free in Review Mode (no credit card, no time limit) and only pay when you want to send live reminders and run automation. It serves B2B service teams globally, with GDPR-aware data handling and a DPA as trust signals, and its late-payment tools are built around the EU Late Payment Directive (2011/7/EU).
