AP automation: What it is, how it works, and benefits for AP teams

Imagine your finance team scrambling to locate a missing vendor invoice that was submitted 2 weeks ago. Meanwhile, another invoice sits buried under a pile of paper, now past due and accruing late fees. Manual invoice processing creates a long list of such problems, from data entry mistakes and approval bottlenecks to misplaced documents and frustrated vendors.

Accounts payable automation eliminates much of this manual work by digitizing and automating the invoice-to-pay process. Businesses are rapidly shifting to automated AP processes to reduce errors, speed up processing, strengthen vendor relationships, and get better cash flow visibility.

What is AP automation?

Accounts payable automation is the process of using technology to streamline and digitize tasks in the AP workflow. AP automation tools can handle invoice processing, data entry, approval routing, payment execution, and more to reduce errors and improve efficiency.

You might automate every step in the process, from invoice receipt to payment, or just the highly repetitive parts of your workflow. For example, you might capture supplier invoices electronically, match them against purchase orders (POs), and route them for approval without needing human intervention.

Manual vs. automated accounts payable

Traditional AP workflows rely on paper-based systems and manual processing. Finance teams spend countless hours entering invoice data by hand, routing physical documents for approvals, and managing files full of vendor paperwork. This creates multiple opportunities for errors and eats up time that would be better spent on strategic work.

Manual AP workflows also create bottlenecks. Invoices stuck on desks wait for approvals, vendor inquiries require digging through physical files, and your month-end close becomes a scramble to locate and process outstanding invoices. The lack of visibility means finance teams often operate blindly, unsure of their current payment obligations or cash flow commitments.

AP automation solves these challenges. Digital workflows replace paper trails, intelligent software handles data extraction and validation, and electronic approval routing eliminates physical handoffs. The result is faster processing and better visibility into every invoice, from receipt to payment.

Key features of AP automation software

AP automation platforms typically include several core capabilities that work together to optimize your invoice processing workflow:

• Optical character recognition (OCR): Automatically extracts data from invoices, POs, and receipts, eliminating manual data entry and reducing transcription errors
• ERP and accounting system integrations: Connects seamlessly with your existing financial software to sync vendor data, charts of accounts, and payment information without duplicate data entry
• Automated approval routing: Routes invoices to the appropriate approvers based on predefined rules, amount thresholds, or department codes, speeding up the approval process
• Digital audit trails: Maintains comprehensive records of every action taken on an invoice, from initial receipt through final payment, supporting compliance and internal controls in AP
• Real-time reporting: Provides dashboards and reports on processing times, spending patterns, vendor performance, and outstanding obligations for better financial visibility

These features work in concert to create a seamless, efficient accounts payable operation that reduces manual effort while improving accuracy and control.

Challenges of manual accounts payable

Manual AP processes create inefficiencies that drain resources and cause frustration for both internal and external partners:

• Time-consuming data entry: Manual invoice processing requires staff to input vendor information, line items, and payment details by hand, taking up time that would be better spent on financial planning and analysis (FP&A)
• Risk of human error and payment delays: Typing mistakes, misplaced invoices, and approval bottlenecks lead to incorrect payments, duplicate charges, and late fees that damage vendor relationships and increase costs
• Limited visibility and control: Paper-based systems make it nearly impossible to track invoice status, monitor spending patterns, or generate real-time reports for financial decision-making
• Difficulty reconciling invoices and maintaining compliance: Matching purchase orders, receipts, and invoices is unnecessarily complex. Paper audit trails can be misfiled or lost, making compliance more challenging

Automation software addresses these pain points by reducing manual touchpoints and providing visibility into the entire accounts payable process. This allows finance teams to focus on value-added activities while improving accuracy.

Benefits of AP automation

Automating accounts payable delivers improvements across operations, turning finance teams into strategic partners rather than reactive processors:

• Faster processing times: Instead of spending hours manually copying invoice details and chasing approvals, automation processes invoices in minutes. A 2023 study by Ardent Partners found that organizations using automation accelerate invoice processing time by 81%. This frees up staff to focus on analyzing spending trends and negotiating better vendor terms.
• Reduced errors and late payments: Automation eliminates common mistakes such as duplicate payments or incorrect account codes that occur when manually entering hundreds of invoices, while automatic payment scheduling prevents late fees
• Improved cash flow visibility and control: Finance teams can instantly see which payments are due this week versus next month through comprehensive dashboards, rather than digging through spreadsheets and paper files to understand cash flow timing
• Enhanced compliance and audit readiness: When auditors request documentation for a specific vendor payment from 6 months ago, automated systems instantly provide the complete approval trail and supporting documents
• Cost savings: Businesses can redirect staff time from repetitive data entry tasks to strategic projects such as vendor negotiations and cash flow optimization, while reducing expenses for paper storage, printing, and overnight invoice delivery

How does AP automation work?

Accounts payable automation technology simplifies the entire payment process by using software to handle tasks that traditionally require manual work. For example, say you receive an invoice from a vendor. The typical steps would look like this:

Step 1: Invoice capture

The AP automation software captures invoices from multiple sources automatically. Whether vendors send invoices via email, upload them through a supplier portal, or deliver paper documents that get scanned, the system automatically receives and begins processing each invoice.

This eliminates the common problem of invoices getting lost in email inboxes or buried in paper stacks, while accommodating different vendor preferences for invoice delivery methods.

Step 2: Data extraction

OCR technology reads invoice documents and automatically pulls out key information such as vendor names, invoice numbers, line items, amounts, and due dates. The software learns to recognize different invoice formats and layouts, becoming more accurate over time.

This replaces the tedious manual process of typing invoice details into your accounting system, reducing data entry time from minutes per invoice to seconds, while eliminating typing errors.

Step 3: Purchase order matching

The system compares invoices against existing purchase orders and receipts to verify that you actually ordered and received goods or services. When discrepancies arise, such as quantity differences or pricing variations, the software flags these exceptions and routes them to the appropriate team members for review.

This 3-way matching process prevents unauthorized payments and catches billing errors before money leaves your account.

Step 4: Routing for approval

Based on your company's approval hierarchy and spending limits, the software automatically sends invoices to the right people for authorization. Approvers receive email notifications with invoice details and can review and approve payments directly from their computers or mobile devices.

The system tracks approval status in real time and sends reminders for pending approvals, eliminating delayed payments and strained vendor relationships.

Step 5: Payment scheduling and processing

The system schedules approved payments according to your cash flow preferences and vendor payment terms. You can optimize for early payment discounts, avoid late fees, or align payments with your cash flow cycles.

The software integrates with your bank or payment processor to execute electronic payments, issue checks, or process ACH transfers automatically on the scheduled dates.

Step 6: Tracking and auditing

Every action in the AP process includes timestamps, user information, and document attachments, creating a complete audit trail. Finance teams can access reports showing payment status, spending by department or vendor, and outstanding obligations.

This visibility helps with cash flow planning, budget monitoring, and regulatory compliance, while making year-end audits smoother since all documentation is digitally organized and searchable.

Which AP tasks can be automated?

You can automate several core functions of your accounts payable workflow to save time and improve accuracy. Automated workflows mean each vendor invoice moves through the correct steps, from receipt to payment, without manual intervention.

The key is knowing your AP workflow’s starting and stopping points and the triggers that move you from one step in the process to the next. Here are a few standard steps in an accounts payable workflow:

Invoice processing

Through AI and automation, employees don’t have to enter invoice data manually. Your technology captures invoices electronically and extracts critical information automatically.

For example, your AP process might start when a client emails an invoice as a PDF attachment. OCR technology scans, reads, and converts the PDF into text data. Then, the system automatically compares and matches the invoice to your PO to make sure the invoice is accurate.

Approvals

Instead of manually chasing approvals through email, you can set up custom rules to route invoices to the appropriate team members for review. Reviewers can approve invoices with a few clicks, often from a mobile device, to keep the work flowing.

Payments

Once a reviewer approves the invoice, the system schedules the payment, reducing the risk of late payments and penalties.

Reconciliation

Next, the system reconciles payments with the bank statements to verify that the payment amounts and payees align. This happens behind the scenes, with AP team members involved only if there’s an issue, such as an invoice that doesn’t match the PO or a cleared check on the bank statement that doesn’t match the transaction recorded in your accounting system.

Reporting

Automation makes it easy to generate real-time reports on your AP process. For example, the system can generate an AP aging report that summarizes all outstanding payables, broken down by vendor and date. Up-to-date information on invoice statuses, cash flow, and vendor payments gives you greater visibility and control over your finances.

How to implement AP automation

Implementing an accounts payable automation process can feel overwhelming, but starting small and focusing on the most impactful areas can help you achieve some quick wins to propel you forward.

Here’s each step of the process broken down—from planning and implementing to automation in action—with additional details for each stage:

Planning

Before diving into automation, start by assessing your current workflows to lay the groundwork for automation:

• Assess your current AP processes: Identify inefficiencies in workflows such as invoice receipt, coding, approval, and payment
• Document and standardize workflows: Create clear processes for invoices, approvals, and payments for seamless integration with automation tools
• Set goals and define priorities: Define measurable AP goals such as reducing invoice processing time or improving accuracy

Choosing the right AP automation tool

Once you’ve mapped out your processes and goals, the next step is selecting the right AP tool:

• Choose AP tools with flexible features: Evaluate tools based on features such as ERP integration, customizable workflows, and fraud prevention
• Ensure compatibility with existing systems: Verify that the tool integrates with your accounting software and other systems to prevent conflicts

Implementing AP automation

After selecting a tool, begin testing and training your team:

• Pilot the solution with a small team: Test the tool on a small scale, resolve issues, and gather feedback for refinement
• Train your team and manage change: Provide training and emphasize how automation reduces workload and improves efficiency

Automation in action

Now, you can begin automating specific AP processes to unlock efficiency, accuracy, and consistency in your workflows:

• Capturing invoices: Use tools to digitize invoices from email or paper formats, pulling key data into a centralized system to eliminate manual entry
• Coding invoices: Automate classification by department or project, ensuring accurate application of general ledger codes
• Matching invoices: Match invoices to POs and receipts to speed up approvals and prevent duplicate or overpayments
• Routing approvals: Automate invoice routing with predefined rules so approvers can quickly review and approve from any device
• Scheduling and sending payments: Automate payments via ACH, wire transfer, or credit card to pay vendors on time

And lastly, make sure to measure and optimize performance by tracking metrics such as processing time and cost savings to refine workflows and maximize automation benefits.

Common challenges and best practices for implementation

While AP automation delivers clear benefits, successful implementation requires careful planning. Look out for common obstacles that can derail your timeline:

• Change management and team buy-in: Staff may resist new technology due to fear of job displacement or additional work during transition periods. Address concerns early by communicating how automation eliminates tedious tasks and allows staff to focus on higher-value analytical work.
• Data migration and integration issues: Moving vendor data and connecting with existing accounting systems can create technical issues and data inconsistencies. Work with your software provider to map data fields, test integrations in a sandbox environment, and plan for downtime during the switchover period.
• Training and onboarding: Teams need to learn new workflows and software interfaces, which can temporarily slow productivity during the adjustment period. Develop a phased training approach that starts with key users, provides hands-on practice sessions, and offers ongoing support resources such as video tutorials and help documentation.
• Vendor communication and setup: Educating suppliers about new invoice submission processes and portal access can create confusion and resistance to workflow changes. Communicate changes well in advance, provide clear instructions and training materials, and designate points of contact to help vendors navigate the new system smoothly.

Successful AP automation implementation hinges on thorough preparation, clear communication, and patience as your team and vendors adapt to more efficient processes.

AP automation success stories from Ramp customers

To help you visualize how AP automation might work in your company, here are a few examples of AP automation case studies and how businesses implementing Ramp have benefited from the experience.

How REVA Air Ambulance simplified invoice data entry

Instead of manually entering invoice details into your system, accounts payable automation software can capture data from digital invoices and automatically populate fields in your accounting software, eliminating human error.

When REVA Air Ambulance, a medical transportation company, streamlined its AP processes with Ramp, the AP team could simply drag and drop invoices directly into the program and code them automatically rather than manually entering and coding each invoice. For a company processing roughly 2,500 invoices per month, cutting invoice processing from 15 or 20 minutes per invoice to 3 minutes per invoice meant significant time savings.

How Skin Pharm automated payment scheduling

You can automatically schedule and send payments after reviewers approve an invoice to ensure you never miss a deadline or incur late fees because someone on the AP team is on vacation. That’s one of the benefits enjoyed by Skin Pharm, a beauty brand with a line of at-home skin care products and 11 clinics across the southern US.

Skin Pharm implemented Ramp Bill Pay to automate its accounts payable and pay its bills automatically, regardless of whether a team member is in the office. This automation gives the company’s finance leader peace of mind knowing they’re not falling behind on vendor payments.

How Quora took advantage of real-time reporting with Ramp integrations

Instead of manually compiling reports at the end of every month, automated systems can generate real-time reports on your AP operations, giving you visibility into outstanding payments, processing times, and the company’s overall financial operations.

Quora, the social question-and-answer website and online knowledge marketplace, had clunky AP processes holding it back. Vendors would email bills to an AP email address, then the Quora team would download those invoices, save them to Google Drive, and link them to the bill in the company’s ERP.

But since employees couldn’t access the ERP, they had to handle approvals \via email, and emails were often lost. Making matters worse, tools in the company’s fintech stack didn’t integrate easily with the ERP, so closing the books meant a lot of manual data entry.

Once the company implemented Ramp, it streamlined and automated its AP processes by integrating directly with its ERP, NetSuite. Finance Manager Richard Gobea noted that the bidirectional sync between Ramp and NetSuite allows the company to see changes in real time because there are just three steps from invoice processing to payment and reporting.
