Key Takeaways

• The Collection Effectiveness Index measures how efficiently a company collects accounts receivable within a specific period.
• CEI is a more accurate gauge of collections performance than DSO because it factors in delinquent accounts.
• A good CEI score is typically above 80%, with top-performing companies achieving 90% or more.
• Automation in accounts receivable significantly improves CEI by accelerating cash collection and reducing bad debts.

What is the Collection Effectiveness Index (CEI)?

The Collection Effectiveness Index (CEI) is a performance metric used by finance teams to evaluate the efficiency of their collections efforts. Unlike traditional measures like Days Sales Outstanding (DSO), CEI accounts for both the total amount of receivables due and the amount actually collected, providing a more comprehensive view of collection practices.

Formula:

CEI = (Total Collections ÷ (Beginning Receivables + Credit Sales – Ending Receivables)) × 100

This calculation helps businesses assess how successful they are at collecting payments from customers, especially those with past-due invoices.

Why Use the Collection Effectiveness Index?

While DSO measures the average number of days it takes to collect payments, CEI offers a more real-time look at collections performance, particularly useful when managing large volumes of monthly credit sales.

Benefits of using CEI include:

• Pinpointing gaps in collections efficiency
• Highlighting accounts that require escalation or follow-up
• Enabling better cash flow forecasting
• Supporting more accurate reporting on bad debts and delinquent accounts
  
  

How to Calculate Collection Effectiveness Index

To calculate CEI, you'll need:

• Beginning Receivables: Outstanding receivables at the start of the period
• Credit Sales: Sales made on credit during the period
• Ending Receivables: Uncollected receivables at the end of the period
• Total Collections: Payments collected within the same period

Example:

• Beginning Receivables: $100,000
• Credit Sales: $200,000
• Ending Receivables: $80,000
• Total Collections: $220,000

CEI = (220,000 ÷ (100,000 + 200,000 – 80,000)) × 100 = (220,000 ÷ 220,000) × 100 = 100%

A 100% CEI indicates that all collectible receivables were collected during the period.

What is a Good Collection Effectiveness Index?

In general, a CEI of 80% or higher is considered strong.

Top-tier finance teams aim for 90%+, indicating tight control over their accounts receivable and fewer delinquent accounts.

If your CEI consistently falls below 70%, it may signal issues in your collections automation process, such as poor follow-up, customer disputes, or outdated systems that slow down cash collection.

How to Improve Your Collection Effectiveness Index

Improving CEI requires a combination of proactive practices and smart technology:

1. Automate Your AR Processes

Use AR automation tools to:

• Send reminders and invoices automatically
• Match payments in real time
• Escalate overdue invoices using workflows
• Reduce manual errors and follow-up delays

2. Incentivize Early Payments

Offering discounts for early payments can help reduce the days it takes to collect, especially from consistent payers.

3. Segment and Prioritize Collections

Group customers by payment behavior. Focus your collections efforts on accounts that are consistently late or represent larger balances.

4. Monitor CEI Monthly

Make CEI a key performance indicator and review it regularly alongside DSO to identify trends and collections inefficiencies.

5. Integrate with Your ERP

A well-integrated ERP system enables better visibility into outstanding receivables, monthly credit sales, and collections progress—all critical for improving CEI.

The Collection Effectiveness Index is more than just a metric—it’s a powerful tool that reveals how well your business is managing its revenue cycle. By calculating CEI and using automation to streamline your AR process, you can shorten your cash collection cycle, reduce bad debts, and boost your company’s financial health.
