The conventional answer to rising DSO is headcount — more people to chase more invoices. But the most effective AR teams aren't the largest ones. They're the ones who've eliminated the delays that happen between an invoice going overdue and anyone actually doing anything about it.
Here's the step-by-step process for reducing DSO by 30% without adding staff. These steps are ordered by impact — start at the top.
Most AR processes start after an invoice is overdue. The biggest single change you can make is sending a friendly reminder 7 days before the due date. This catches customers before they forget and eliminates the 'I never saw the invoice' excuse. Teams that add pre-due reminders see DSO drop by 8–12% on its own.
Inconsistent follow-up is the most common DSO driver. If your first chase happens 14 days overdue and the next one is 3 weeks later, you're losing weeks of collection time every cycle. The effective cadence: Day 1 overdue, Day 7, Day 14, Day 30. Consistent timing trains customers on your expectations.
When an invoice hits 30 days overdue, sending the same person a firmer email rarely works. Escalate to the customer's finance manager or CFO. This isn't aggressive — it's a recognition that the AP contact may not have authority to expedite payment.
80% of your DSO problem comes from 20% of your customers. Identifying which customers consistently pay late — and treating them differently from Day 1 — is the highest-leverage segmentation you can do. Courtasy tracks payment patterns and automatically adjusts follow-up timing and tone per customer.
Manual AR means delays — someone has to remember to send each email, escalate each account, and update each status. Automation removes the human latency from the process entirely. When an invoice goes overdue, the next action triggers automatically. Teams using Courtasy report reclaiming 4–6 hours per week from manual AR tasks.
If your current DSO is 60 days and you implement all five steps above, a 30% reduction brings you to 42 days. For a company with $5M in ARR, that's roughly $240,000 of working capital freed up — capital that was tied up in unpaid invoices. That's real cash you can use to invest in growth.
