5 Accounts Receivable KPIs You Should Track (Beyond DSO)
DSO is important, but it doesn't tell the whole story. Discover the 5 advanced AR metrics that reveal the true health of your cash flow.
Most business owners know their bank balance. Some know their Days Sales Outstanding (DSO). But very few track the metrics that actually predict whether they will get paid next month.
DSO is a useful lagging indicator. It tells you how long it took to get paid. But it can be misleading. A sudden spike in sales can artificially lower your DSO, hiding a collection problem. Conversely, a drop in sales can raise your DSO even if your collections are performing perfectly.
To truly understand your cash flow health, you need to look deeper. Here are the 5 KPIs that sophisticated finance teams use to predict cash flow, and how you can track them too.
1. Collection Effectiveness Index (CEI)
While DSO measures time, CEI measures quality. It answers the question: "Of the money that was available to collect this month, how much did we actually collect?"
It is expressed as a percentage. A CEI of 100% means you collected every dollar that was due. A CEI of 50% means you left half your potential cash on the table.
Why it matters: CEI tracks your team's performance more accurately than DSO. If your sales drop but your team collects well, CEI stays high (accurate) while DSO might spike (misleading).
2. Average Days Delinquent (ADD)
DSO tells you the average time to payment (e.g., 45 days). But if your payment terms are Net 30, a 45-day DSO means you are paid 15 days late.
ADD isolates that "late" portion. It measures the average number of days invoices are overdue after the due date.
Formula: DSO - Best Possible DSO
Why it matters: This is your "efficiency gap." If your ADD is rising, it means your customers are stretching their terms further, or your follow-up process is slowing down.
3. Right Party Contact Rate (RPC)
This is a tactical metric for your collection efforts. It measures how often your follow-up attempts actually reach the decision-maker.
If you make 100 calls and only talk to the right person 5 times, your RPC is 5%.
Why it matters: You can't collect money from voicemail. A low RPC usually means you have bad contact data (calling the main switchboard instead of the finance director) or you are calling at the wrong times. Improving RPC is the fastest lever to improve cash flow.
4. Accounts Receivable Turnover Ratio (ART)
This ratio measures how many times per year you collect your average accounts receivable balance.
Formula: Net Credit Sales / Average Accounts Receivable
A high ratio implies an efficient collection process and high-quality customers who pay debts quickly. A low ratio implies a collection process that needs improvement or credit policies that are too loose.
Why it matters: It tells you how fast you are turning credit sales into cash. In a high-interest environment, a higher turnover ratio means you need less working capital to run the business.
5. Percentage of High-Risk Accounts
This isn't a standard formula, but it is a critical health check. What percentage of your total AR is concentrated in customers who are structurally late (e.g., always 60+ days)?
If 80% of your overdue debt is held by 3 clients, your problem isn't "collections". It's client management. You need to fire those clients or change their terms to upfront payment.
Why it matters: It stops you from treating all overdue invoices the same. High-risk accounts need a different strategy (and perhaps a different price point) than reliable payers who just missed an email.
How to Track These Without a PhD
You don't need complex ERP systems to track these. A simple spreadsheet update once a month works for most SMBs.
But the real power comes from action. Knowing your CEI is 60% is only useful if you have a way to improve it.
This is where Dunwise fits in. By automating the outreach (increasing your Right Party Contact Rate) and consistently following up (reducing Average Days Delinquent), Dunwise directly impacts these KPIs.
