What is collection rate in accounts receivable?

Collection rate is a simple measure of AR effectiveness: the percentage of the invoices a business sends out that it eventually gets paid on. A collection rate of 95 percent means the business collects on 19 out of every 20 invoices it issues. The five percent gap represents write-offs, bad debt, and amounts settled below the full invoice total. For most service businesses, collection rates below 90 percent indicate a material AR problem worth investigating.

Collection rate and DSO are related but distinct. DSO measures speed — how quickly money arrives. Collection rate measures completeness — how much of what was invoiced actually gets collected. A business can have a low DSO with a low collection rate, or a high collection rate with a high DSO. The ideal is fast and complete, which requires both tight follow-up cadence and disciplined write-off decisions.

Improving collection rate typically requires earlier, more consistent follow-up. The relationship between collection rate and age is stark: invoices worked in the first week recover above 85 percent, while invoices that sit past 90 days with no contact typically recover below 22 percent.
