Managing accounts payable has become more critical than ever. Effective management of this critical function can impact financial health, cash flow, and overall efficiency. And the key to staying on top of accounts payable lies in monitoring and tracking the right Key Performance Indicators (KPIs).

Accounts Payable KPIs are a set of metrics that provide valuable insights into the performance and effectiveness of the accounts payable process. By monitoring these KPIs, teams gain a deep understanding of their financial position, identify potential bottlenecks, and proactively address payment-related issues.

But why should you monitor accounts payable KPIs? The answer lies in the immense benefits it brings.

First and foremost, monitoring accounts payable KPIs allows you to optimize cash flow management. By keeping a close eye on metrics such as Days Payable Outstanding (DPO) or Cash Conversion Cycle (CCC), you can ensure timely payments to vendors and suppliers, maintain good relationships, and potentially negotiate better terms. This, in turn, helps secure discounts, avoid late payment penalties, and improve overall financial stability.

In addition, tracking KPIs related to invoice accuracy and processing time enables you to identify inefficiencies in your accounts payable process. Metrics like Invoice Processing Cycle Time or Accuracy Rate provide real-time insights into bottlenecks, redundancies, and potential risks. By addressing these issues promptly, you can streamline processes, increase productivity, and reduce the risk of errors, which ultimately leads to more cost-effective operations.

Furthermore, monitoring accounts payable KPIs helps you gain visibility into your spending patterns and manage vendor relationships effectively. Metrics such as Spend Under Management, Vendor Performance, or Purchase Order Compliance shed light on your purchasing habits, highlighting opportunities to consolidate vendors, negotiate better pricing, and ultimately reduce costs. By leveraging these insights, you can make strategic decisions, allocate resources efficiently, and foster long-term partnerships with suppliers.

In this blog, we will look into the best accounts payable KPIs and the reasons behind their importance. We will discuss best practices for tracking these KPIs, leveraging tech and automation to streamline processes.

What are accounts payable (AP) KPIs?

Accounts payable KPIs are like dashboard gauges for your financial health when managing vendor payments. These metrics help you understand how efficient and effective your AP process is. Tracking AP KPIs often results in improved performance and optimized workflows.

What are the challenges AP KPIs solve?

AP KPIs help business teams manage vendor relationships and manage liquidity. Regarding pain points that AP KPIs cure, it fixes inefficiencies and risks. It also renders a good amount of cost savings for your AP teams. Now, let’s delve into these buckets—

Challenges that AP KPIs solve

Why are AP KPIs important?

Metrics always help AP teams to understand and verify whether their progress is aligned with overall business goals. Moreover, AP teams work cross-functionally - any mistake could create a ripple effect.

Some essential reasons for tracking them include —

- Identify process bottlenecks: KPIs point out slow processing times, high touchless invoice rates, and inefficient resource allocation, highlighting areas for automation and streamlining workflows.

- Reduce costs: By identifying and addressing inefficiencies, you can significantly decrease costs associated with invoice processing, manual work, and errors.

- Negotiate better deals: Understanding per-vendor spending patterns helps you identify key suppliers and potential cost savings through negotiations.

- Improve credit standing: Maintaining prompt payments and positive relationships with vendors ensures good credit standing, potentially leading to better borrowing terms and conditions.

- Stronger supplier relationships: Positive relationships with vendors can lead to preferential treatment, better pricing, and early access to new products or services.

10 AP KPIs with Formula, Definition, Example, and Impact

1. Days Payable Outstanding (DPO)

DPO is the average number of days it takes a company to pay its suppliers after invoices are due. You can calculate DPO using the formula below —

DPO = (Average accounts payable * 365) / Total purchases on credit

Example

If your average accounts payable is $10,000 and your total purchases on credit in a year are $100,000, your DPO is (10,000 * 365) / 100,000 = 36.5 days.

Impact

💡 Low DPO: Indicates faster payments, potentially leading to better supplier relationships, early payment discounts, and improved cash flow.
💡 High DPO: Can signal slow processing, delayed payments, potential compliance issues, and damage to supplier relationships.

2. Cost per Invoice Processed

Cost per invoice processed is the average cost associated with processing a single invoice, including labor, technology, and other expenses.  You can calculate it using the formula below —

Cost per invoice processed = Total AP processing costs / Number of invoices processed

Example

If your total AP processing costs are $5,000 per month and you process 500 invoices, your cost per invoice is $5,000 / 500 = $10.

Impact

💡 Low cost: Suggests efficient automation, streamlined workflows, and reduced manual work, leading to cost savings.
💡 High cost: Indicates potential inefficiencies, excessive manual work, or outdated technology, requiring process improvement and automation.

3. Invoices Processed per Employee

This AP metric can be defined as the average number of invoices processed by each employee in a specific period. You can calculate it using the below formula —

Invoices processed per employee = Number of invoices processed / Number of AP employees

Example

If your team processes 2,000 invoices per month with 5 employees, your invoices per employee are 2,000 / 5 = 400 per month.

Impact

💡 High number: Indicates high individual and team productivity, suggesting efficient training, clear workflows, and potential automation.
💡 Low number: May point to inefficiencies, lack of training, or insufficient resources, requiring process improvement or additional staff.

4. Percentage of Invoices Processed Straight Through

This AP metric is defined as the percentage of invoices processed electronically without requiring manual intervention. You can calculate it using the below formula —

% of invoices processed straight through = (Number of invoices processed without exceptions / Total number of invoices) * 100%

Example

If your team processes 200 invoices with 20 requiring manual intervention, your straight-through processing rate is (180 / 200) * 100% = 90%.

Impact

💡 High percentage: Indicates efficient automation, clear data, and minimal errors, suggesting process optimization and data quality.
💡 Low percentage: Points to data inconsistencies, manual intervention needs, or potential automation issues, requiring data cleaning and workflow adjustments.

5. Early Discount Capture Rate

The early discount capture rate is the percentage of discounts captured by paying supplier invoices early. You can calculate it using the below formula —

Early discount capture rate = (Amount of early discounts captured / Total potential early discounts) * 100%

Example

If you captured $1,000 in early payment discounts with a total potential of $2,000, your capture rate is ($1,000 / $2,000) * 100% = 50%.

Impact

💡 High rate: Indicates effective cash flow management and proactive payment practices, leading to cost savings and improved financial health.
💡 Low rate: Suggests missed opportunities for cost savings, potentially due to inefficient workflows, late payments, or lack of awareness of discounts.

6. Percentage of Late Payments

This metric can be defined as the percentage of invoices paid after the due date.

% of late payments = (Number of late payments / Total number of invoices) * 100%

Example

If you have 10 late payments out of 200 invoices, your late payment rate is (10 / 200) * 100% = 5%.

Impact

💡 Low rate: Indicates timely payments, good supplier relationships, and compliance with terms, minimizing potential penalties and risks.
💡 High rate: This can signify cash flow issues, inefficient processes, or poor supplier communication, leading to compliance risks, damaged relationships, and potential late fees.

7. Accounts Payable Turnover Ratio

The accounts payable turnover ratio measures how efficiently a company pays its suppliers by calculating how often accounts payable are turned over within a period.

AP Turnover Ratio = Total purchases on credit / Average accounts payable

Example

With $100,000 in purchases and $20,000 in average accounts payable, the turnover ratio is $100,000 / $20,000 = 5 times per year.

Impact

💡 High ratio: Indicates faster payments, efficient use of credit, and potentially improved supplier relationships.
💡 Low ratio: Suggests slow payments, potential cash flow issues, or inefficient use of credit lines.

8. Average Approval Time for Invoices

This metric tracks the average time it takes for invoices to be approved before payment. You can calculate it using the below formula —

Average approval time for invoices = (Total approval time for all invoices / Number of invoices) / Number of approval steps

Example

If 200 invoices take 3 days each for approval with 2 steps, the average approval time is (200 invoices * 3 days) / (200 invoices * 2 steps) = 1.5 days per step.

Impact

💡 Short time: Indicates efficient approval processes, potentially leading to faster payments and improved supplier satisfaction.
💡 Long time: Suggests bottlenecks or inefficiencies in the approval process, delaying payments and potentially harming relationships.

9. Vendor Satisfaction Score

Vendor satisfaction score measures the satisfaction level of your suppliers through surveys or feedback mechanisms. The formula varies based on the chosen metric (e.g., the average score on a feedback survey)

Example

If your vendor satisfaction score is 80% on a 100-point scale, it indicates good relationships and overall satisfaction.

Impact

💡 High score: This signifies positive supplier relationships, potentially leading to better prices, terms, and early payment discounts.
💡 Low score: Suggests issues with payment timelines, communication, or dispute resolution, requiring improvement.

10. Percentage of Invoices with Disputes

This metric tracks the percentage of invoices requiring clarification or dispute resolution before payment.

% of invoices with disputes = (Number of disputed invoices / Total number of invoices) * 100%

Example

If you have 5 disputes out of 200 invoices, your dispute rate is (5 / 200) * 100% = 2.5%.

Impact

💡 Low rate: Indicates accurate data, clear communication with suppliers, and efficient dispute resolution processes.
💡 High rate: Suggests potential data inconsistencies, communication issues, or inefficient dispute resolution processes, leading to delays and supplier dissatisfaction.
