KPIs for Accounts Payable: How to Improve AP Performance

Tracking the right KPIs for Accounts Payable is essential for finance teams looking to optimize efficiency, minimize errors, and ensure smooth operations. Without these key metrics, AP teams may face delays, increased costs, and compliance risks.

In this guide, we’ll break down the most critical KPIs for Accounts Payable, why they matter, and how automation can improve AP performance.

Why these KPIs for Accounts Payable matter

Accounts Payable (AP) is a critical function in any organization. Among other tasks, AP departments are responsible for processing invoices, managing supplier relationships, and executing payments. They must perform these tasks while ensuring accurate, timely, and compliant operations with all relevant regulations. However, managing AP teams and processes effectively can be challenging, particularly for organizations with a high volume of invoices.

Effective AP management requires visibility into key performance indicators (KPIs). These KPIs help organizations track and measure the efficiency of invoice processing, payment accuracy, and cost control.

Monitoring KPIs for Accounts Payable helps businesses:

• Reduce invoice processing times and avoid late payments.
• Improve cash flow management and financial planning.
• Minimize manual errors and compliance risks.
• Optimize supplier relationships through timely payments.

Now, let’s explore the top KPIs for Accounts Payable and how they drive AP efficiency.

Essential KPIs for Accounts Payable organizations need to track

⏳Invoice processing time

One of the most crucial KPIs for Accounts Payable is invoice processing time, which measures how long it takes to process an invoice from receipt to payment.

A slow invoice cycle can lead to delays, late fees, and missed discounts. Invoice processing time can be an indicator of low productivity among the team. It may also signal inefficiencies in the process. Automation helps AP teams accelerate invoice processing by eliminating manual data entry and approval bottlenecks.

Industry Benchmark:

Best-in-class AP teams process invoices in under 5-7 days in industries such as manufacturing, retail, and consumer goods, or in large enterprises. Market differences also exist, as regulations and tech maturity impact performance.. For example, APQC reports a 10.1-day average across industries, while best-in-class achieve ~2.8 days.

How to improve this KPI?

• Implement AI-powered invoice capture and approval workflows.
• Reduce manual data entry through automation.
• Regularly monitor your Analytics Suite to identify areas for improvement.

🔢Daily invoice processing volume by agent

Daily invoice processing volume by agent measures how many invoices an AP agent processes each day. This KPI is important for tracking the productivity and efficiency of AP team members.

A low processing volume per agent could indicate workflow inefficiencies, system issues, or training gaps. Conversely, a high daily processing volume suggests strong AP automation adoption and well-optimized processes.

By monitoring this KPI, businesses can:

• Establish performance benchmarks for AP teams.
• Measure progress toward targets.
• Identify bottlenecks in invoice processing.
• Optimize workload distribution for maximum efficiency.

How to improve this KPI?

• Automate manual tasks like data entry and invoice routing.
• Provide AP analytics dashboards to track team performance in real time.
• Implement AI-powered AP automation to reduce workload per agent.

💰Cost per Invoice processed

Cost per invoice is the average cost of processing a single invoice. Measuring this KPI helps AP teams understand processing expenses. High processing costs can impact an organization’s profitability, especially when invoice volumes are high.

The cost per invoice includes both direct costs (such as labor) and indirect costs (such as overhead).

Industry Benchmark:

Best-in-class AP teams process invoices for $1.42 to $4.00, depending on industry complexity and labor costs. In contrast, manual processes cost between $10 and $15 per invoice.

How to lower this KPI?

• Reduce manual intervention with touchless invoice processing.
• Use AP automation to cut operational costs.

🤖Invoice Accuracy

Invoice accuracy measures the percentage of invoices processed without errors. This KPI is crucial because invoice errors can lead to payment delays, increased administrative costs, and compliance risks.

Common causes of invoice errors include incorrect data, missing PO details, and supplier discrepancies. Poor accuracy can strain supplier relationships, delay approvals, and even result in financial penalties.

Achieving a high invoice accuracy rate requires strong collaboration between the company and its suppliers. Master data management plays a key role in ensuring invoices contain accurate information, such as purchase order (PO) details and tax codes.

How to improve this KPI?

• Ensure high-quality master data for supplier and invoice details.
• Automate data validation to detect discrepancies before processing.
• Implement AP automation solutions that flag potential errors before invoices enter the approval workflow.

📆Days Payable Outstanding (DPO)

DPO measures how long a company takes to pay suppliers after receiving an invoice. Balancing DPO is key to optimizing cash flow without harming supplier trust.

Industry Benchmark:

There is no one-size-fits-all “ideal” DPO. Generally, companies aim to maximize agreed payment terms while maintaining supplier relationships. Benchmarks typically range from 30-50 days, depending on industry, market, and financial strategy.

How to optimize this KPI?

• Leverage AP analytics to optimize payment cycles.
• Improve invoice processing to take advantage of early payment discounts.

📊Invoice exception rate (percentage of invoices with deviations)

The invoice exception rate measures the percentage of invoices that deviate from the standard process due to discrepancies or errors. A high invoice exception rate signals inefficiencies in AP workflows, often caused by missing data, errors, or compliance issues.

Industry Benchmark:

Top AP teams maintain an exception rate below 10%, while the industry average is 20-22%. For example, Ardent Partners reports an average invoice exception rate around 20-22.5% in recent years

How to reduce this KPI?

• Implement AI-powered invoice validation.
• Ensure accurate supplier data and automated compliance checks.
• Identify trends and patterns in invoice errors.
• Implement automatic invoice rejections reason.
• High e-invoicing adoption.

⏰On-time payments percentage

Payment timeliness tracks the percentage of invoices that are paid within the agreed-upon payment terms. Paying invoices on time is essential for avoiding penalties, maintaining supplier trust, and improving financial stability.

In some industries, timely invoice payments are critical to ensuring that suppliers continue providing the necessary services and goods, preventing supply chain disruptions. While avoiding account blocks is important, maintaining good payment behavior strengthens supplier relationships and enhances negotiation opportunities.

Industry Benchmark:

World-class operations often achieve 90-95% on-time payment rates. Across industries, approximately 70-75% of supplier invoices are paid on time..

How to improve this KPI?

• Set up automated approval reminders, escalations, and delegations.
• Use tracking dashboards to monitor invoice due dates.
