From 21 days to 8: How one firm cut invoice collection time with SLA timers

When a growing consulting firm came to OONH, their average invoice took 21 days to collect. Their finance team was spending hours each week manually sending reminders, tracking who owed what, and escalating to partners when clients went silent.

The Problem

No automated reminders. No escalation when invoices went overdue. No visibility into which invoices were at risk. The team relied entirely on manual spreadsheet tracking and memory.

The OONH Solution

We set up a 4-stage automated collection sequence: friendly reminder at 3 days, firm follow-up at 7 days, escalation to account manager at 14 days, and partner notification at 21 days. Each stage had its own SLA timer with visual status indicators.

The Result

Within 6 weeks, average collection dropped from 21 days to 8. The finance team saved 12 hours per week on manual follow-ups. Partners gained real-time visibility into at-risk invoices before they became problems.
