From 21 Days to 8: How SLA Timers Cut Invoice Collection Time

The Problem

A mid-size agency was averaging 21 days to collect on invoices. The finance team sent reminders manually, but with 200+ active invoices, many slipped past 30 days. By then, clients had moved on mentally.

The OONH Setup

We configured a 4-stage collection sequence: gentle reminder at day 3, firm reminder at day 7, escalation to account manager at day 14, and final notice at day 21. Each stage had its own SLA timer. The moment payment was received, the sequence stopped automatically.

The Result

Average collection dropped from 21 days to 8. The finance team went from spending 15 hours/week on follow-ups to under 2 hours — mostly just reviewing the dashboard.
