Overview

In the realm of finance, the efficiency and effectiveness of an accounts payable (AP) department are critical for maintaining a company’s liquidity, optimizing cash flow, and building strong supplier relationships. But how do you measure the success of your AP operations? Key Performance Indicators (KPIs) offer a clear, quantitative method to assess performance, spot areas for improvement, and ensure that the department runs smoothly.


Here are the top 7 Accounts Payable KPIs every organization should monitor to measure success:

1. Days Payable Outstanding (DPO)

DPO measures how long, on average, it takes a company to pay its suppliers after receiving an invoice. It’s a critical KPI because it directly impacts your company’s cash flow. A higher DPO indicates that you’re holding onto cash longer, which might be beneficial for liquidity, but it could strain relationships with suppliers. Conversely, a low DPO might indicate strong relationships with suppliers but could strain cash reserves.

To calculate DPO:

DPO= (Accounts Payable/COGS)×Number of Days
Where:
  • Accounts Payable is the amount a company owes its suppliers.
  • COGS (Cost of Goods Sold) represent the direct costs of producing goods sold by the company.
  • Number of Days is typically 365 for annual calculations.

2. Invoice Processing Time

This KPI measures how long it takes to process an invoice from the moment it’s received to when it’s approved for payment. Streamlining this process can significantly impact efficiency and cost-saving efforts. Delays in processing can lead to missed payment deadlines, strained supplier relationships, and late fees.

3. Cost per Invoice Processed

This KPI measures the total cost incurred in processing a single invoice, including labor, technology, and other overheads. Organizations that rely heavily on manual processes tend to have higher costs per invoice, while those that have embraced automation usually see this KPI drop significantly.

To calculate:

Cost per Invoice Processed= (Total Number of Invoices Processed/Total Cost of Invoice Processing)
Where:
  • Total Cost of Invoice Processing includes all associated costs, such as labor, technology, overhead, and any other relevant expenses for processing invoices.
  • Total Number of Invoices Processed is the total number of invoices that have been processed in each period.
Lowering the cost per invoice processed is directly related to improving the overall profitability of the AP function. Automating AP processes can reduce manual labor costs, improve accuracy, and accelerate turnaround times.

4. Invoice Exception Rate

Invoice exceptions occur when discrepancies arise between an invoice and a purchase order (PO) or delivery receipt. The invoice exception rate is the percentage of invoices that cannot be processed without manual intervention. These issues could be due to incorrect data, missing information, or mismatches between the invoice and corresponding documents.


A high invoice exception rate indicates inefficiencies in your AP process, leading to delayed payments, additional manual work, and potential supplier dissatisfaction. Reducing this rate leads to smoother operations and faster payment cycles.

5. Percentage of Invoices Paid on Time

This KPI measures the percentage of total invoices that are paid on or before the due date. Timely payments help maintain good supplier relationships and avoid late fees, ensuring the company’s reputation as a reliable business partner.


Paying invoices on time builds trust with suppliers and can lead to better terms, such as discounts for early payment. Monitoring this KPI helps ensure the AP department is not contributing to unnecessary costs like late fees or strained relationships.

6. Discount Capture Rate

Many suppliers offer early payment discounts as an incentive for timely payment. The discount capture rate measures the percentage of these available discounts that your AP team successfully captures. By taking advantage of these opportunities, companies can directly improve their bottom line.
To calculate:
Discount Capture Rate= (Total Discounts Available/Discounts Captured)*100
Where
  • Discounts Captured = The dollar amount of early payment discounts the company took advantage of.
  • Total Discounts Available = The total dollar amount of early payment discounts that were available to the company.
Capturing early payment discounts reduces overall expenses. If your organization misses out on available discounts, it might indicate inefficiencies in your invoice approval or payment processes.

7. Supplier Satisfaction Score

While many Accounts Payable KPI’s are centered on internal performance, supplier satisfaction is a critical external indicator of success. This score measures how satisfied your suppliers are with your AP process, based on factors like payment timeliness, communication, and issue resolution.


Supplier satisfaction impacts your company’s supply chain. Happy suppliers may offer more favorable terms or discounts, while dissatisfied suppliers might impose stricter terms or prioritize other customers over you.

Optimizing Accounts Payable with Technology

Achieving success in accounts payable is increasingly tied to leveraging technology. Automating AP processes—such as invoice capture, validation, and approvals—can have a profound impact on most of the KPIs mentioned. Not only does automation reduce invoice processing time and costs, but it also decreases errors, lowers the invoice exception rate, and enhances overall efficiency.


With automation, businesses can ensure real-time data accuracy, improve cash flow management, and take advantage of early payment discounts.
