5 Key Accounts Receivable Metrics to Assess Your AR Performance

The top priorities of companies are to close deals and keep customers happy. 

These don’t always translate into healthy finance. Ultimately, cash is the fuel that powers businesses. 

While most businesses acknowledge this fact, few prioritize effective cash collection. It's common for companies to measure invoices to assess performance but not keep careful track of whether those invoices are paid on time, if paid at all. 

Well… What’s the meaning of making a sale if you don’t get paid promptly for it?

Effective accounts receivable management can play a crucial role in your company's cash flow. 

The good news is, you can improve your A/R performance helped by the right analytics. 

We recently discussed the importance of Days Sales Outstanding, giving you a good view of your A/R performance. But it doesn’t have to be the only key metric to consider. 

Today, we’ll present five pieces of data it may be helpful for your business to collect. 

Remember, most businesses don’t track their AR performance. So no matter what you track, you’ll be going in the right direction if you track at least something.

1. Days Sales Outstanding

Days Sales Oustanding Formula

Days Sales Outstanding is an essential A/R metric to track. To put it simply, DSO measures how quickly -- or slowly -- your company collects payments. It’s one of the key metrics you’ll want to share with investors as it shows you’re building a healthy, cash-driven business.

A high DSO means it takes a long time for customers to pay. A low one means people pay quickly, so your company has steady cash flow coming in. 

Days Sales outstanding Graph

There are several methods to calculate your DSO, a simple formula is:

(Accounts Receivables at the end of the period) / (Gross revenues over the period) * (Number of days in the period)


  • Your net annual turnover is $600,000
  • At the end of the year, you have $100,000 unpaid invoices

You DSO is: ($100,000)/($600,000)*(365)= 61 days

Ideally, DSO won't exceed your payment terms by more than 50%. This means if you expect clients to pay within 30 days, your DSO should be 45 or below. 

You may not meet this ideal. Most businesses focus on revenue and don’t even track this metric. Without tracking it, you cannot measure progress. 

Regardless of the method, as long as you track DSO consistently and implement efficient account receivable collection processes, you’ll be able to set targets and monitor whether collections efforts are paying off.

2. Best Possible Days Sales Outstanding 

Best Possible DSO Formula

Identifying your best possible DSO is important as a baseline measure to compare to your DSO. 

It considers only current receivables that aren't past due yet. This distinguishes it from the broader DSO measure, which also includes past-due bills when estimating how long it takes to get paid. 

Best possible DSO is a best-case scenario. It shows how quickly your company will collect if everyone pays their bills on time.

Ideally, your best possible DSO would equal your DSO. That never happens in practice, though. 

But while some gap between DSO and best possible DSO is normal, a large discrepancy means your collection process isn't as effective as it should be. 

Closing that gap involves taking the right steps to implement efficient collection processes.

We’ve seen substantial improvement when our users implemented systematic processes to ensure all unpaid invoices were followed up with a reminder. 

You must be careful, though. Systematic reminders don’t mean flat, impersonal automated emails. Most of the time, these end up in the bin without even being read. 

You need to tailor reminders to your customers’ specificities and avoid impersonal reminders as much as you can. You can, for example, automate the first reminder but send a highly personalized email when a larger account payment becomes late. This will also help understanding why payment is late and contribute to nurturing the customer relationship.

3. Average Days Delinquent 

Average Days Deliquent Formula

Average days delinquent measures how far behind customers typically fall on payments. Specifically, it refers to the average time between when an invoice was due and when the client paid it. It can be measured across the company’s client database and at an account level to help you identify clients that rarely pay on time. 

ADD isn’t used as a standalone metric. Typically, it’s measured in the long term and coupled with other key metrics, such as DSO, to help you assess whether collections efforts are trending in a positive direction. The two metrics should most often work in tandem, although that won't necessarily be the case if a change in payment terms or another shift occurs. 

For example, if a large outstanding invoice is finally paid, the ADD will quickly improve. However, that doesn’t mean your collection has suddenly become effective. 

That’s why you shouldn’t look at your ADD in a snapshot. Instead, calculate it over time and evaluate it along with DSO. This will help you better understand the trend of your AR performance.

4. Collections Effectiveness Index 

Collections Effectiveness Index Formula

Collections Effectiveness Index, or CEI measures in percentage your ability to get funds from customers within a given period. It's typically calculated monthly, although you can choose to track it over any period you like.

The closest this percentage is to 100%, the best. Although a perfect 100 is theoretically possible if your collections efforts are flawless, in general, this number should be above 80%.

Let’s take an example:

  • Receivable Balance at the beginning of the month (Initial Receivables): $100,000
  • Current Monthly Credit Sales: $40,000
  • Payments Received on the Current Month Receivable: $20,000
  • Payments Received for Outstanding Receivables: $60,000

Your receivables at the end of the month will be: 

Current Month Sales - Payments Received on the Current Month Receivable = $20,000

And the total Receivables Balance at the end of the month will be: 

Receivable beginning of the month + Current month Sales - Payments Received for Outstanding Receivables - Payments Received on the Current Month Receivable = $60,000

Then, you can apply the above formula:

($100,000 + $40,000 - $60,000) / ($100,000 + $40,000 -  $20,000) x 100 = 67%

We’ve prepared an excel spreadsheet to help you calculate this every month:

While DSO is focused on how long it takes for your company to get paid, CEI considers the amount of the outstanding invoices and measures how effectively your company collects total payments due. 

Some AR metrics can be compared with competitors to assess how quickly your company collects payments relative to the industry’s average. CEI isn't used for this type of benchmarking against peers. Instead, it’s an internal measure of the A/R teams’ performance. 

5. Accounts Receivable Turnover Ratio

Accounts Receivanle Turnover Ratio Formula

 This metric assesses how effectively your company manages credit and how quickly your clients pay their bills. A higher ratio is preferred and suggests your A/R team is efficient and that your clients repay debts rapidly. 

Let’s take an example: 

  • Your net sales for the year is $100,000
  • Your accounts receivable at the beginning of the year is $8,000, and at the end of the year, it is $12,000. This means your average accounts receivable is $10,000.

Here, your A/R turnover ratio is $100,000/$10,000 = 10.

By dividing the number of days of that period by the A/R turnover ratio, you can calculate your average collection period. In our example, your average collection period would be 365 / 10 = 36.5 days.

A good A/R turnover ratio is generally high and indicates that you have an efficient collections process. However, you may want to capture sales ahead of the competition or keep clients in dire economic situations. There, it won’t be a priority to have a higher ratio.

How to Analyze and Track These Key Metrics

Each account receivable metric requires you to collect substantial data, with accuracy. You'll also want to collect the data consistently over time to compare your performance and identify how changes and optimizations impact it. 

Excel spreadsheets have the advantage of being cost-free, but they are limited when it comes to keeping track of advanced analytics. Your time is valuable and should be spent on value-added activities, like resolving an overdue payment dispute, instead of focusing on making calculations that could easily be automated (removing the human error factor too!).
