Measuring Collections Performance

Watch days sales outstanding

Days sales outstanding (DSO) measures the average time it takes to collect payment after a sale. It is the single most telling indicator of collections health: a rising DSO means cash is taking longer to arrive, even if sales look healthy. Track it month to month rather than fixating on one figure — the trend reveals far more than any single reading. Compare it against your trading terms, too. If your terms are thirty days but your DSO is fifty-five, the gap is the real cost of slow payment, and it is exactly what a tighter process is meant to close.

Track the ageing profile

Beyond a single average, watch how your receivables are distributed across time. A few figures tell most of the story:

• Percentage current versus overdue — how much of your ledger is behaving.
• Value sitting beyond 90 days — your hardest-to-recover, highest-risk bucket.
• Movement between bands month to month — whether debts are clearing or sliding older.

A growing tail of old debt is an early warning, even while total receivables look stable. Reading the shape, not just the total, lets you act before a problem becomes a write-off.

Measure your own activity

Outcomes matter, but so does effort. Track how promptly reminders go out, how many accounts reach a payment promise, and how many of those promises are kept. These activity measures show whether your process is being run consistently or has quietly lapsed. If kept-promise rates are low, the problem may be how commitments are secured rather than the customers themselves. Measuring your own follow-up — not just the customer's behaviour — is what separates a managed collections function from hopeful chasing, and it points clearly to what to fix.

Turn numbers into action

Metrics are only useful if they change what you do; tracked and then ignored, they are just decoration. A rising DSO might prompt earlier first contact; a growing 90-day bucket might trigger faster escalation; a low kept-promise rate might mean tightening how you confirm commitments on the phone. The discipline is to draw one clear action from each review rather than admiring the dashboard. Review your figures on a regular rhythm — monthly is enough for most small businesses — and pick one or two changes to act on each time, then check next month whether they moved the number. To calculate overdue figures and the cost of slow payment as you review, the Merion tools can do the arithmetic for you.
