What is AP Automation?

Accounts Payable Automation, often referred to as AP Automation, employs technology and software to manage and streamline the accounts payable function within an organization. It automates tasks such as invoice processing, vendor communication, approval workflows, and payment management. The purpose of AP automation is to create a streamlined, more efficient process, transforming this vital part of an organization’s operations from a time-consuming manual exercise to a seamless, hassle-free proceeding.   

By eliminating manual, paper-based processes, AP automation brings increased efficiency, accuracy, and cost savings to the accounts payable department.


How does AP Automation work?

Accounts Payable automation solutions replace the manual, time-consuming tasks performed by AP teams with efficient, automated processes. Let’s take a look at a few of the key aspects of how AP automation works.

Electronic Invoice capture

Electronic invoice capture is the first step in AP automation. E-invoicing involves the digital processing of invoices, extracting relevant data such as vendor details, invoice numbers, amounts and dates. AP automation systems can capture invoices in various formats, such as PDF, XML, EDI or scanned paper invoices and may be delivered by email, through supplier portals, or using FTP or web services. This digitization eliminates the need for manual data entry, reducing errors and speeding up the processing of invoices.

Automated Invoice Verification 

In AP automation, digital invoice data undergoes verification through data-matching algorithms. These algorithms cross-reference invoice details with purchase orders (PO) and goods receipts (GR) to validate the information, preventing fraud and ensuring accurate receipt of goods or services without price or quantity discrepancies. Advanced systems can automate payment posting upon achieving a 3-way match (PO, invoice, and GR) or a 2-way match (invoice and GR), streamlining the verification process.

Automated approval and Exception handling workflows

After verification, invoices that cannot be automatically posted will be processed using automated workflows. Approval workflows route invoices to buyers for review and approval. Exception handling workflows route invoices with a vendor, price, quantity, or tax discrepancy to the appropriate business user for resolution. The workflows can be tailored to your organization's specific requirements, with designated individuals or departments reviewing and approving invoices electronically based on the vendor, cost center or other criteria. The system sends automated reminders and escalations to business users to ensure invoices are processed as quickly as possible.

Payment Facilitation

Once an invoice is processed, it is posted for payment. At this point, the accounts payable department can facilitate payments based on the vendor’s predefined payment terms. It can automatically schedule payments, taking into account discounts for early payments, to ensure vendors are paid accurately and on time.

Reconciliation reporting

The flow of funds to vendors can be tracked by the AP automation software in real-time. The software can instantly generate reconciliation reports that provide the accounting team with insights into actual and planned cash flows. Having detailed information on outstanding payments, allows organizations to manage cash flow more effectively and make informed financial decisions.

Archiving and auditing

Finally, AP automation systems archive all relevant documents, ensuring easy access for future reference and audits. This not only keeps your records organized but also aids in compliance with regulatory requirements. The system can generate audit reports that facilitate responses to periodic internal and external audits, further enhancing transparency and accountability across the entire automated accounts payable process.

Why is AP Automation important for businesses?

Organizations continually strive to improve efficiency, reduce costs, and enhance their overall operational performance, and automating accounts payable through the utilization of software solutions has emerged as a game-changer in this regard. It offers a host of benefits that make it a critical tool for businesses of all sizes. Let’s take a look at a few key reasons why AP automation is important for businesses:

Streamlining Processes

Traditional, manual accounts payable processes are inherently time-consuming and prone to errors. With AP automation, routine tasks like data entry, invoice matching, and approval workflows are automated, reducing the time required for invoice processing. This streamlined process not only accelerates operations but also ensures greater accuracy in financial transactions. As a result, employees can redirect their focus towards more strategic tasks, adding value to the business.

Saving Time and Money

One of the most significant advantages of AP automation is the significant time and cost savings it brings. Reduced reliance on manual labor for data entry and processing translates into lower operational costs. Moreover, automating payment processes can lead to early payment discounts, saving businesses even more money. This newfound efficiency results in faster vendor payments, improving relationships and potentially opening doors to more favorable terms.

Processing More Invoices without Increasing Staffing Levels

As businesses grow, so does the volume of financial transactions. This growth often necessitates hiring additional accounting staff to manage the increased workload. AP automation solutions alleviate this need by enabling staff to handle higher transaction volumes with ease. The solutions can auto-post simple invoices based on defined business rules and help staff complete complex processing tasks with less effort. This way, organizations can rapidly expand the business and keep administrative overhead under control.

Businesses That Benefit the Most from an Automated AP workflow

AP automation can benefit a wide range of businesses, but there are a few types of enterprises that will really make the most of a streamlined process.
For example, large enterprises that handle a high volume of invoices can really benefit, as the optimization of routine tasks on a large scale can have a massive impact in terms of saving time and money.
Retail and ecommerce companies can also benefit, as processing high volumes of supplier invoices and payments can be made more efficient.
There are clear benefits for manufacturing, hospitality, finance and service-based companies too. On the whole, any business that deal with suppliers and invoicing on a significant scale will benefit from AP automation. 

What are the benefits of AP Automation?

Embracing AP automation is not just a strategic move; it's a vital step toward staying competitive and resilient in the evolving business landscape. The benefits of AP automation include reduced costs, improved efficiency, enhanced financial control, and more. 

Reduced Costs and Overheads

AP automation reduces costs and overheads by eliminating the need for manual data entry, physical storage of documents, and paper-based processes. Automation streamlines the AP workflow, reducing the time and labor required for tasks like invoice processing, approval, and payment processing. 

Improved efficiency and Accuracy from errors

AP automation improves efficiency by automating routine tasks and reducing the potential for human errors. It aids the processing of invoices, minimizes the risk of data entry mistakes, and ensures that invoices are matched accurately with purchase orders and receipts. With AP automation, invoices are processed accurately and efficiently, saving time and resources.

Improved Time efficiency

AP automation expedites the entire accounts payable process, enabling faster invoice approvals and payment processing. Invoices move through the system at a much faster pace thanks to automated workflows. These workflows not only accelerate the time to payment but also streamline operations, allowing staff to concentrate on more strategic activities that drive the business forward. Improved time efficiency also benefits suppliers who receive payments sooner, potentially leading to better relationships and negotiated discounts.

Financial visibility & control

Automated accounts payable processes increase visibility and control over vendor payments. Organizations gain real-time insights into financial data so they can monitor cash flow, track spending, and analyze vendor performance, which enhances their decision-making capabilities.

Compliance & fraud prevention 

AP automation includes built-in controls and audit trails that help organizations meet compliance requirements. The system enforces approval hierarchies and processes, ensuring adherence to internal policies and external regulations. Moreover, automation systems can detect and prevent fraud by flagging irregularities or unauthorized changes in the AP process, contributing to a more secure financial environment.

Real-time reporting 

Automated accounts payable solutions often offer real-time reporting and analytics capabilities. These reports provide instant insights into spending patterns, payment history, and other financial data. This transparency empowers organizations to pivot and adapt quickly in a dynamic business landscape.

ESG Sustainability

Environmental, Social, and Governance (ESG) sustainability is a growing concern for businesses. AP automation reduces the environmental impact by significantly reducing paper usage, contributing to sustainability initiatives, and demonstrating a commitment to responsible business practices.

Problems of manual accounts payable processes

Manual AP processes have long been the standard in the world of finance and accounting. However, these traditional methods can cause a number of issues to arise, which can be mitigated by implementing an automated process. Let’s consider a few problems caused by using a manual accounts payable process. 

Manual data entry

One of the most significant challenges of manual AP processes is the need for extensive data entry. Data entry is a labor-intensive, time-consuming task that often involves transcribing data from invoices, purchase orders, and other documents into accounting systems. Not only is this process tedious, but it's also highly susceptible to human error.

Time consuming 

Entering invoice data manually into an ERP of financial accounting system is incredibly time-consuming. It takes time for AP users to handle, sort, and route paper invoices for review and approval.  This can quickly lead to a backlog which could ultimately slow down operations and damage relationships with suppliers.

Human error

Manual data entry can be a monotonous task, which increases the likelihood of mistakes being made. Even the most diligent employees can make mistakes, which can lead to inaccuracies, potentially resulting in overpayments, underpayments, and reconciliation issues. 

Invoice tracking and management

Manual invoice tracking and management is time-consuming and prone to errors, especially when dealing with a high volume of invoices. The risk of lost invoices is a significant concern in manual processes. Managing a large number of invoices manually slows down the overall process, requiring careful attention to ensure accurate payments and proper data logging. Switching to an automated accounts payable system eliminates these issues, creating a more efficient and error-resistant invoice management process. 

Delays and inefficient processes

A manual accounts payable process can ultimately lead to delays and inefficiency. Whether it’s the slow process of tracking invoices, routing approvals or the hassle of having to deal with paper documents, there are many in the process that can lead to delays and ultimately impact a company’s ability to operate steps efficiently.
