Automated payment reminders — 70% fewer late payments

THE SITUATION

An independent accountant managing 40+ clients spent 4–6 hours per month manually chasing late-paying clients. Reminders came too late or were forgotten, worsening delays.

WHAT WE BUILT

We configured an n8n workflow that reads open invoices from their accounting software (Pennylane), and automatically sends personalised email reminder sequences at D+15, D+30, and D+45. Messages are written with Claude to sound natural, not robotic.

THE RESULT

70% reduction in late payments in 6 weeks. The accountant reclaimed 5 hours per month — and their 30-day collection rate went from 58% to 89%.
