IDC MarketScape for AP Automation

Global businesses face a rising volume of supplier invoices, but many accounting departments still rely on inefficient, costly, and error-prone manual processes. This creates a strong push to digitize operations through accounts payable (AP) automation.

The AP automation market reflects this momentum—it is expected to more than double from $5.4 billion in 2025 to $11.8 billion by 2029, growing at a 21.4% CAGR, according to The Business Research Company’s Accounts Payable Automation Global Market Report 2025.

This guide defines “what is AP automation,” describes how AP automation works, and identifies its benefits and potential ROI (return on investment) for scaling global businesses and nonprofit organizations.

What is AP Automation?

AP automation uses software to automate supplier invoice processing tasks from invoice capture, verification, and coding to PO matching, approval routing, payments, and reconciliation. It replaces manual accounts payable department tasks and provides paperless document management for payables.

AP automation replaces the accounts payable team’s time-consuming, bottlenecked, and error-prone manual data entry and traditional manual workflows. A scalable and automated accounts payable system reduces hiring needs and provides better financial data and spending visibility. Instant payment reconciliation significantly accelerates the financial close. 

Accounts payable software for automation is more straightforward and flexible, with greater affordability than accounts payable outsourcing.

Key Takeaways

  • AP automation software enables efficient, paperless processing of accounts payable invoices, replacing error-prone manual accounts payable processes. 
  • Accounts payable automation improves tax compliance, global regulatory compliance, risk management, and internal controls. 
  • With real-time spend visibility provided by AP automation with embedded AI tools, businesses can more effectively analyze and reduce their business costs. 

Key Challenges of Manual Accounts Payable 

The key challenges of manual accounts payable include:

  1. Inefficiencies: Time-consuming manual data keying, recalculation, verification, matching, GL coding, reconciliation, global payments, tax compliance, and filing of invoices and supporting documents 
  2. Process bottlenecks: Delays in invoice verification, matching, and approvals
  3. In-office presence: Remote work isn’t possible for many steps in a paper-based accounts payable system, including invoice data entry, verification, document matching, approvals, and check printing, signing, and mailing
  4. Human errors: Undetected human errors are more likely in manual AP systems
  5. Invoice processing delays: late fees, lost early payment discounts, and poor supplier relationships
  6. Paper documents: Missing or lost documents, and paper storage costs 
  7. Overpayments: Higher risk of paying fraudulent and duplicate invoices
  8. Less spend visibility: A lack of real-time visibility for business spending 
  9. Poor global regulatory compliance: A lack of international country knowledge may impair the company’s ability to comply with global regulations for payments

How Does Accounts Payable Automation Work?

Accounts payable (AP) automation works by onboarding suppliers, digitizing invoices, and streamlining routine AP tasks with AI and robotic process automation (RPA). The software automates invoice processing and recording—from verification and PO matching to approvals, payments, and reconciliation–while providing real-time visibility into business spend.

AP automation also enables fully paperless document management, reducing errors and costs while improving efficiency.

Supplier Onboarding 

In accounts payable automation, a supplier portal can be used for supplier onboarding and automated payment status notifications. Self-service supplier onboarding collects W-9 and W-8 tax forms, as well as the supplier’s contact and payment information details. 

Invoice Digitization and Data Capture with OCR and AI

For automation of accounts payable processes, accounts payable automation software converts paper invoices into a standard digital format, then pushes the invoices through a virtual workflow with minimal human intervention, culminating in supplier payments. Some AP automation systems accept electronic invoices from e-invoicing systems. 

At the beginning of the invoice management process, AP automation software uses optical character recognition (OCR) to extract information from invoices digitally. Some AP automation systems utilize machine learning (ML), a subset of artificial intelligence (AI), to enhance accuracy and recognize patterns over time.

Application of Business Rules

In most cases, AP teams eliminate the need for manual business processes through custom rules. The elimination includes everything from approval hierarchies to PO matching and acceptable data variances. Business rules for payments will flag exceptions that indicate potential errors requiring follow-up. 

Automated GL Coding and Invoice Routing

The accounting system manages all invoice coding and routing through a digital workflow. Artificial intelligence leverages experience to suggest specific ledger codes or approval routing. 

3-Way or 2-Way Matching

The AP automation system digitally matches Invoices with POs and receives reports in 3-way matching or only with POs in 2-way matching when a goods received note (GRN) isn’t required for that type of purchase. 

Approval Routing

An AP automation system includes automated rules for routing invoices for payment approval. 

Invoice Payment and Scheduling

As part of the AP automation process flow, the system schedules global invoices for batch payments using due dates, preferred EFT payment methods for payment processing, and best practices. It displays batch cash requirements. Invoice payment dates can be modified by authorized members of the finance team before the CFO or Controller approves a payment batch. 

Payment Reconciliation

The best AP automation systems provide instant payment reconciliation after syncing with the integrated ERP system or accounting software. 

Real-time Spend Visibility and Analytics

AP automation provides real-time, multi-entity spend visibility when the integrated ERP or accounting software provides those capabilities. AI can be used to provide business intelligence for reducing business spend. 

Why Automate Accounts Payable?

An AP automation solution streamlines payables processes and accounting operations, saves money and reduces costs, improves efficiency and internal controls, and grants your business a sharp competitive edge. 

AP automation technology replaces manual workflows with touchless automation, playing a crucial role in optimizing financial systems and controls, reducing fraud and errors, improving global compliance, and facilitating collaboration across teams. 

Accounts payable automation enables an organization to onboard suppliers through a vendor portal, process invoices digitally, gather business intelligence, and enhance vendor relationships. 

Top Accounts Payable Tasks to Automate

Automation helps teams increase accuracy or cut processing times, leading to cost savings. 

Compared to manual data entry, accounts payable automation software significantly improves payables-related tasks like:

Invoice matching

This method, known as three-way PO matching, allows you to match invoices and supporting documents, such as purchase orders and shipping receipts. 

Data entry 

Manual data entry is a primary time-consuming task in invoice payment processes performed by the AP department. Automating the data capture of all source documents is a key benefit for businesses. This paperless process is quicker and less prone to error.                

Coding invoices

AP automation increases the efficiency and functionality of approval workflows. It enables a business to establish rules and AI-generated GL coding that sets the correct general ledger code for each invoice. 

Approval routing

When a business automates accounts payable, it streamlines the approval process. AP automation enables electronic routing to all necessary approvers in the invoice processing cycle. 

Global payments and reconciliation

Global payments can be automated in large batches of hundreds or thousands of invoices using AP automation. Batch payments with multiple payment methods and currencies can be instantly and automatically reconciled with ERP syncing and accounts payable automation. 

How to Automate Accounts Payable

To automate accounts payable, start by integrating AP automation software with your ERP or accounting system. This replaces manual AP tasks with a streamlined, digital process, saving time, reducing errors, and strengthening financial controls.

Steps to implement AP automation:

  1. Form an implementation team. Assign roles and responsibilities to manage the rollout.
  2. Define workflows and business rules. Bring in consulting help if needed to align automation with your processes.
  3. Integrate and customize. Configure the system for your ERP/accounting setup.
  4. Train employees and suppliers. Provide access, training, and support so adoption runs smoothly.

With the right AP automation solution, you can eliminate manual busywork, accelerate payments, and gain real-time visibility into every dollar spent.

Modernize AP. Cut Costs. Gain Control.

Eliminate manual tasks, speed up approvals and payments, and gain real-time visibility into every dollar spent.

What are the Benefits of AP Automation?

AP automation provides efficiency and improves controls. It also enables businesses to gain real-time visibility into their spending, allowing them to reduce costs and improve profitability. 

Additionally, the trend toward increased globalization of suppliers across different countries necessitates timely payments in local currencies while adhering to global regulatory compliance, further contributing to the rationale for digital transformation.

10 benefits of AP automation are:

  1. Increasing accounts payable efficiency for lower invoice processing costs
  2. Eliminating paper-based, manual processes
  3. Implementing segregation of duties (SoD) for better internal control 
  4. Reducing fraud and errors 
  5. Providing more functionality to ERP or accounting systems 
  6. Increasing oversight and transparency
  7. Simplifying tax compliance and global regulatory compliance
  8. Reducing invoice processing delays 
  9. Making global payments more efficient and cost-effective
  10. Freeing finance team time for more value-added projects to improve business results

1) Increasing Accounts Payable Efficiency

End-to-end payables process streamlining and automation remove process bottlenecks and increase efficiency. 

2) Eliminating Paper-Based, Manual Processes

Paper-based systems for invoice processing are inefficient because they require manual data entry, verification, and matching steps, and introduce human errors. Paper systems for accounts payable also require filing time and storage costs for archived records. Documents may be missing, misfiled, or lost. 

3) Implementing Segregation of Duties for Better Internal Controls

AP automation software is designed to strengthen the segregation of duties and provide role-based access for stronger internal control. AP automation also provides an automated audit trail. 

4) Reducing Fraud and Errors

AP automation lowers the risk of invoice fraud and payment errors, such as duplicates, by enforcing stronger controls and preventing overpayments.

Built-in business rules flag exceptions before payments are made, while automation ensures critical checks, like invoice total verification, aren’t skipped under time pressure. For fraud prevention, suppliers can be validated through automated taxpayer ID matching (TIN matching) and detection tools that flag suspicious payee behavior.

5) Providing Additional ERP Functionality

AP automation software that works as an integrated add-on to your company’s ERP system or accounting software fills the gap in needed functionality that a traditional accounts payable system lacks. 

6) Increasing Oversight and Transparency

AP automation enhances visibility by entity and, combined with multi-entity ERP functionality, and provides stakeholders with greater transparency into invoices, payments, and business spending. Business intelligence, powered by AI queries, enables businesses to make informed decisions about achieving cost reductions. 

7) Simplifying Tax Compliance and Global Regulatory Compliance

AP automation collects W-9 and W-8 forms upfront and generates 1099/1042-S reports. Some solutions also integrate with tax software to e-file and distribute forms automatically, ensuring compliance with minimal effort.

8) Reducing Invoice Processing Delays

AP automation provides the necessary functionality for businesses to expedite their invoice processing, ensuring the timely recording of supplier invoices, taking advantage of early payment discounts, and avoiding late fees. 

9) Making Global Payments More Efficient and Cost-Effective

For businesses paying suppliers worldwide, using local payment methods is far more efficient and affordable than relying on costly international wire transfers. Strong AP automation platforms include built-in foreign exchange (FX) tools, and some also offer hedging options to protect against currency fluctuations between invoice and payment dates.

10) Freeing Finance Team Time for Value-Added Projects

By automating manual tasks like payment reconciliations, AP automation frees finance teams and controllers from repetitive work. This allows them to focus on strategic analysis and decision support that help reduce costs, drive revenue, and advance their careers.

Key AP Automation KPIs and ROI Metrics

Setting and revisiting key performance indicators (KPIs) is easier with AP automation. Tracking KPIs and cash flow through a manual system is nearly impossible. 

AP automation built into your ERP helps boost KPIs and ROI by taking manual work out of the accounts payable process. You’ll see fewer bottlenecks, faster invoice turnaround, and less time your team spends chasing down approvals, which can also cut down on overtime costs. 

Plus, as your company grows, AP automation scales with you, handling more invoices across multiple entities without needing to bring on extra headcount—helping you keep future costs down.”

Types of Accounts Payable KPIs

KPIs to track for accounts payable include:

  • Invoice cycle time
  • % touchless invoices
  • Cost per invoice
  • Error rates
  • Early payment discounts captured

KPI Performance Benchmarks Table

Accounts Payable KPIDefinition
Invoice Cycle TimeThe duration of invoice processing time is measured from invoice receipt through invoice payment. 
% Touchless InvoicesThe percentage of invoices for which processing is automated without requiring human involvement or manual processes is referred to as touchless.
Cost per invoiceThe cost per invoice is the sum of invoice processing and payment costs, calculated as AP-related costs divided by invoice volume for a specified period.
Error ratesThis KPI is measured as the percentage of invoices that require error correction before further processing. 
Early payment discounts capturedThis KPI measures the percentage of early payment discounts taken by the company versus those offered by suppliers. 

The cost per invoice is calculated by including total accounts payable-related salary and benefit costs for AP staff and accountants, as well as other expenses required in the end-to-end accounts payable process, and then dividing this total by the invoice volume. 

An accounts payable department and finance team can contribute to business results through timely invoice processing, utilizing AP automation to reduce the cost of purchases and enhance gross margins. The Controller or CFO will contribute to business results and cost control by adopting AP automation.
