10 AP Automation Best Practices to Improve Your Accounts Payable Process

For a CFO, accounts payable automation shouldn’t only be about making cash disbursements faster, even though an efficient AP department is a terrific outcome. Automating AP should be seized by CFOs as an opportunity to convert AP processes into a system that gives them visibility and control over where cash is going, who’s accountable for it, and whether the business is being exposed to risk it doesn’t need to take.

Let’s explore the 10 AP automation best practices below not so much for their genuine benefits of efficiency, faster cycle times, and fewer errors, but in terms of what a CFO loses sleep over—controls, cash visibility, fraud exposure, and accountability.

What Is AP Automation? 

AP automation refers to using software and AI to move a vendor invoice from receipt to payment. The software captures invoice data, matches it against purchase orders and receiving records, routes it for approval, and schedules the payment. It replaces human manual entry, error correction, and paper trail creation.

For CFOs, each of those steps is really a control point meant to determine if the order is legitimate, if the goods are in hand, who signed off, and when the cash leaves the company. 

10 AP Automation Best Practices to Improve Your Accounts Payable Process

Every one of the 10 practices below shows up in a typical AP implementation checklist. But a checklist tells you what to do, not why a CFO should care. Each section below highlights the question a CFO needs answered at that step.

1. Assess Your Current AP Workflow

Assessing your current workflow means finding out how much of your AP volume moves cleanly from receipt to payment and how much contains errors that make work loop backward for rework. Or, worse, how much is pushed through anyway despite a real problem. That analysis reveals what needs to be fixed. And the value to be gained by fixing those problems becomes the basis of the business case for AP automation.

 2. Standardize Invoice Intake and Data Capture

Any organization’s invoice intake can be inconsistent. One division receives PDFs in email. Another gets paper in the mail. A supplier might push invoices through a vendor portal nobody in finance checks daily. Each channel may require differently structured data, especially at a company with multiple product lines or business units. To standardize intake, pick one way in and define, upfront, exactly which data fields matter. It’s not a glamorous step; it’s the step that makes every later automation—matching, approval routing, GL coding—possible.

3. Automate Invoice Data Extraction

AI-powered software reads and extracts invoice data automatically, and fast. PwC has found that AI invoice extraction and purchase order matching can cut cycle times by up to 80%. But speed isn’t the CFO’s only concern. The CFO’s issues are validating that the extracted numbers are right and knowing that the company isn’t paying for something it never received. For the CFO, extraction is only valuable with a strong verification layer behind it. Therefore, this step must be viewed as a controls upgrade as much as it is a data-entry upgrade. Otherwise, the organization is automating its risk as well as its process—and making it faster.

4. Use Purchase Order Matching to Prevent Errors

Three-way matching looks like a data-accuracy step. For a CFO, it’s a fraud-and-waste step. It answers the key questions that matter when cash is about to leave the business: Did we order this, did it show up, and was it what we ordered, in the condition and quantity we agreed to? One battery distributor’s finance team found that automated three-way matching cleared 85% of its roughly $600 million in annual vendor bills without anyone touching them. The other 15%, the ones that didn’t match, are exactly the invoices a CFO wants their human AP managers to scrutinize to make sure that fraud and billing errors are intercepted before cash leaves. 

5. Set Up Clear Invoice Approval Workflows

This is where segregation of duties, delegated authority thresholds, and GL coding accuracy converge. Setting up automated approval workflows is the CFO’s opportunity to build controls into the AP process that provide for a sound night’s sleep. This is where multiple sign-offs for large disbursements are decided, including the threshold above which no single approver can act alone; it’s also where routing rules should be written to catch any invoices coded outside an approver’s spending authority. The GL coding piece may be less obvious, but coding accuracy is part of the control that makes sure invoices hit the right budget lines—so the CFO can hold the right managers accountable for them.

6. Integrate AP Automation With Your ERP or Accounting Software

Connecting AP to the general ledger and accounting system is usually seen as an efficiency gain: No more duplicate entry, no more logging in and out of five systems. That’s true, but undersells the point. Without this integration, organizations may still automate payment mechanics but the CFO is flying blind on the company’s current cash position—and payment automation is running on faith, because the system doesn’t really know what’s in the bank or what other commitments are out there.

7. Automate Payment Scheduling and Execution

CFOs aren’t always looking for AP to pay everything the moment it’s due. Their question relates more to cash flow management: “What’s the smartest use of this dollar today?” They’re weighing an early-payment discount against the cost of drawing on a line of credit to fund it, or deciding that a strategic vendor must be paid on time even if a smaller one has to wait. The AP system should schedule payments against the company’s real-time cash position, call out when an early-payment discount is worth capturing, and always leave room for a human to override the schedule when the bigger picture calls for it. Done well, payment automation becomes a treasury tool. Done poorly, it’s autopay—but with a CFO nervously watching the bank balance.

8. Build Strong AP Controls and Fraud Prevention Measures

Controls here split into two categories. One is the classic accounting controls already built into approval workflows: segregation of duties, delegated authority, dual sign-off above a set dollar threshold. The other is newer and less familiar to most finance leaders: technology and security controls. When payments move automatically out of a company’s bank account at the direction of AP software, the security of the connection between the software and the bank becomes a key issue. Can a bad actor exploit that API to get into the AP system and release cash? Or pull sensitive vendor payment data out of it? Payments fraud is a serious threat—76% of US organizations experienced attempted or actual payments fraud in 2025, according to the Association for Financial Professionals’ 2026 survey. Only 17% of organizations use AI to help fight it, which creates a meaningful value proposition for AP automation built with fraud detection in mind from the start.

9. Track AP Performance With the Right Metrics

CFOs will want to track three different kinds of metrics, the last one of which is not so obvious:

Payables health: Days payable outstanding, percentage of early-payment discounts captured, payables turnover. 

AP department efficiency: cost per invoice and cost per payment, broken out by disbursement method. For comparison, the industry benchmark for average cost of processing a single invoice was $9.84 in 2025, with top-performing AP teams averaging $2.65 and all others $12.42, according to Ardent Partners’ “The State of ePayables 2025: AP’s Unfinished Journey.”

Supplier relationships: Are the largest vendors satisfied? What’s the state of their contracts? Your organization should be the best payer to the suppliers that matter most—a KPI that doesn’t show up on a standard AP dashboard.

10. Continuously Optimize Your AP Automation Process

CFOs don’t have the time to personally study their company’s AP automation processes and watch the horizon for emerging technologies that might improve those processes. They should pay AP and IT managers to do that. That means fostering a culture of continuous improvement and backing it up with money—incentive compensation that ties those managers’ bonuses to metrics that measure when the department gets better, such as cost per invoice or exception rate. That way, optimizing the benefits of automated accounting isn’t a nice-to-have—it’s the job.

Proper AP automation software will run whatever rules it’s given, faithfully and at scale. The CFO’s job is to align those rules with the company’s goals.
