Accounts payable (AP) is a critical function within any business. It’s responsible for managing payments to suppliers and streamlining finance operations. However, traditional AP processes can be manual, time-consuming, and prone to errors, stifling productivity. 

Let’s say an employee manually enters an incorrect invoice amount. It could lead to a scenario where you end up overpaying a vendor. This, in turn, results in additional reconciliation efforts, delays in correcting the mistake, and even financial losses. 

That’s where accounts payable automation can help. It’s a system that can identify potential discrepancies, flagging them for review before processing the payment.

Easily Manage Accounts Payable With Hiver

What is Accounts Payable Automation?

Accounts Payable (AP) Automation refers to the systematic use of technologies to replace and enhance the traditional, manual methods involved in the accounts payable process. This process traditionally encompasses the processing, approval, and payment of supplier invoices. 

If you’re managing accounts payable manually, it can get super time-consuming. For instance, in a large organization (over 250 employees),handling a single invoice can take days or even weeks. That’s because it might require multiple levels of approval.

That’s where AP automation comes in. It replaces manual and paper-based processes with automated systems to save time and costs. 

Did You Know: 60% of AP leaders consider lengthy approval times for invoices a major challenge in accounts payable management.

Top Accounts Payable Tasks to Automate

Automating accounts payable processes can significantly improve efficiency and accuracy in financial operations. Here are the top tasks within accounts payable that are often automated:

  • Invoice Processing: Automation helps capture, process, and manage invoices electronically, reducing manual data entry and processing time.
  • Three-Way Matching: Automatically cross-verifying purchase orders, receipt of goods, and invoices to ensure accuracy and prevent fraud.
  • Payment Processing: Scheduling and making payments electronically, managing payment methods, and ensuring timely transactions.
  • Vendor Management: Maintaining vendor information, tracking performance, and managing contracts electronically.
  • Tax Compliance: Automating tax calculations and ensuring compliance with various regulations.
  • Exception Handling: Identifying discrepancies or anomalies in invoices and routing them for resolution without manual intervention.
  • Record Keeping and Archiving: Securely storing and managing documents and transaction records in compliance with retention policies.

How Does Accounts Payable Automation Work

Accounts payable automation streamlines and optimizes the process of managing a company’s outgoing payments. Here’s how it generally works:

  • Invoice Receipt: Automation begins as soon as an invoice is received. Traditional paper invoices are scanned, while electronic invoices can be automatically fetched or received via email. Optical Character Recognition (OCR) technology converts different formats of invoices into a standard digital format.
  • Data Capture and Validation: The system captures relevant data from the invoice such as vendor details, purchase order number, invoice date, total amount, etc. It then validates this information against predefined rules within the system (like matching purchase orders or contracts).
  • Three-Way Matching: In many systems, a three-way match is automated, cross-checking the invoice with the purchase order and the goods receipt note. This ensures that the company pays only for the goods or services correctly ordered and received.
  • Approval Workflow: Based on predefined rules, the invoice is routed to the appropriate person or department for approval. Automation ensures that this process is done quickly, with reminders and escalations in place for any delays.
  • Payment Processing: Once approved, the payment is scheduled and executed according to the company’s payment policies and the payment terms negotiated with the vendor. 
  • Exception Handling: Any invoices that do not match or are flagged for any reason are routed to exception handling queues where staff can review and resolve discrepancies.
  • Reporting and Analytics: The system provides detailed reports and analytics on the accounts payable process, helping identify bottlenecks, track performance, and find opportunities for further optimization.

Benefits of Accounts Payable Automation

Here are some major advantages of automating accounts payable workflows.

How to Implement Accounts Payable Automation

The implementation steps may vary slightly based on the specific needs of different businesses or industries. However, here is a general outline of the implementation steps involved in automating an accounts payable process.

Step 1: Assessment and Planning

  • Analyze existing manual or semi-automated accounts payable processes and identify pain points. 
  • ​​Determine what you want to achieve with automation. Is it improved efficiency, better routing of queries, or hiigher visibility?
  • Establish measurable KPIs to assess the success of the automation project. This may include metrics like invoice processing time, cost per invoice, early payment discounts, etc.
  • Develop a comprehensive project plan outlining the implementation timeline, resource allocation, budget, and milestones.

Step 2: Vendor Selection

  • Explore various accounts payable automation software providers (or select a tool from the list we’ve shared above). Consider factors such as functionality, scalability, integration capabilities, user-friendliness, vendor reputation, and customer reviews.
  • Prepare and issue RFPs to shortlisted vendors, outlining your specific requirements, budget constraints, and implementation timeline.
  • Review and evaluate the received proposals, considering factors such as pricing, implementation support, customization, and ongoing customer support.
  • Based on the evaluation, select the vendor that best aligns with your requirements and negotiate contract terms.

Step 3: Data Preparation and Integration

  • Clean and organize existing accounts payable data to ensure accuracy and consistency. Migrate relevant data to the new automation system.
  • Integrate the accounts payable automation software with other existing systems such as enterprise resource planning (ERP),document management, and financial systems. This allows for seamless data exchange.

If you’re using Gmail to handle vendor communication and invoices, Hiver makes your life incredibly easy. You don’t have to migrate data because it works on top of Gmail.

Step 4: Configuration and Customization

  • Configure the accounts payable automation system to reflect your desired invoice routing and approval hierarchies.
  • Define user roles and permissions within the system to ensure appropriate access levels and segregation of duties.
  • Tailor the system to match your specific business needs by configuring fields, notifications, reminders, and reports.

For instance, a company can establish a hierarchical approval process for invoices based on the invoice amount. Like, invoices under $1,000 can be automatically approved and processed by the accounts payable team.

They can also define specific user roles and permissions within the AP system to ensure appropriate access levels and segregation of duties. 

– Accounts Payable Clerk: Create and process invoices, but cannot approve them.
– Department Manager: Approve invoices within their department’s budget limit.
– Finance Director: Approve invoices without any budget limit.

Step 5: Testing and Training

  • Conduct extensive User Acceptance Testing (UAT) to ensure that the automation system functions as expected. Test various scenarios, including invoice entry, approval workflows, payment processing, and reporting.
  • Train the accounts payable team and other relevant stakeholders on how to effectively use the new system. Address any concerns, provide documentation, and communicate the benefits of the automation to gain user acceptance.

Step 6: Go-Live and Optimzation

  • Roll out the accounts payable automation system to production. Monitor closely during the initial period to address any issues that may arise.
  • Regularly evaluate and optimize the accounts payable process by analyzing key performance metrics, obtaining feedback from users, and implementing necessary enhancements or adjustments.
  • Maintain a strong relationship with the automation vendor for ongoing support, system updates, and addressing any technical issues.
