Cutting DSO is a follow-up problem before it is a technology problem

After a decade in collections, I can tell you that the single biggest lever on DSO is not a discount, a dunning template, or a tougher credit policy. It is whether the follow-up actually happens, on time, every time. It almost never does.

Why consistency breaks down

A collector covering hundreds of accounts triages by hand. The squeaky accounts get attention; the quiet ones age. Reminders go out late, or after a vacation, or not at all. None of this is negligence — it is the math of finite attention against a growing ledger.

The cadence that recovers cash

The teams with the lowest DSO are not the most aggressive. They are the most consistent. A reminder before the due date, a prompt note the day it passes, a firmer follow-up a week later, and a personal call before an account ages into trouble — delivered reliably across every account, not just the loud ones.

• Pre-due reminders prevent more lateness than any post-due escalation.
• Tone should escalate with age, but the cadence should never have gaps.
• Every promise to pay should be captured and followed up on automatically.

Where agents fit

Collections agents make the consistent cadence the floor, not the aspiration. They send tailored outreach across email and voice on a fixed schedule, propose and confirm payment dates within the guardrails you set, and log every promise. The collector stops being a reminder service and starts doing the judgment work — negotiating real disputes, deciding when to escalate, protecting the relationships that matter.

Technology helps, but the insight is older than any model: cash comes in when the follow-up is reliable. Reliability is exactly what software is good at.
