The Top 13 Best Accounts Payable Software in 2023

Accounts payable software is increasingly being used by businesses worldwide. Automated accounts payable software can efficiently manage large volumes of financial transactions between a company and its suppliers, while also automating ancillary activities such as approvals and reconciliations.

AP automation software that is available off the shelf today is either a standalone product or part of a full stack accounting ERP. There are a variety of such tools available today, with varying levels of functionalities and features.

Given the choice of accounts payable software available in the market, it may be difficult for companies to select the right one for themselves. A company’s choice of AP automation software would depend upon its features and the specific needs of the company.

In this article, we look at some of most popular accounts payable software, their core offering, top features, user/customer profiles, and a guesstimate of their price range.

What is accounts payable software?

Accounts Payable (AP), commonly referred to by accountants as “payables,” are the company’s pending short-term debt and liabilities owed to vendors, suppliers, or creditors.

Originally considered a transactional back-office function, the AP process is now considered a hub for critical financial data processing.

The AP process begins with the receipt of the invoice, passes through various levels of categorization, coding, data matching, and AP approvals, and ends with the payment of the invoice.

According to Insider, manual accounts payable processes can take 30 to 90 days. This long timescale arises from interoperability between the steps and the time delays in to-and-fro transitions.

The use of accounts payable software results in a 73% faster processing time. According to a Goldman Sachs, the use of accounts payable automation software also results in 33% reduction in processing costs.

Another compelling driver of AP automation is the elimination of errors. Each AP person in the world, on average, is responsible for 139 faulty invoices every year, which can be avoided with the use of AP software.

Not surprisingly, companies are increasingly adopting software tools for their AP processes. Brainy Insights reports that the global accounts payable automation market will grow to $7.5 billion by 2030.

As with any business workflow optimization tool, there isn’t a one-size-fits-all solution to accounts payable automation. A mandatory feature for your business might be totally unnecessary for someone else’s. This is why customization, extensive documentation, and world-class customer support are usually primary requirements when businesses source accounts payable tools.

The best platforms offer as much customization as your business needs, so you can use or discard specific features based on your operational needs, size, order and vendor volume, and unique documentation requirements.

Since you expect significant customization from your accounts payable software, you’ll also need to look for a platform with sufficient documentation as you adapt to the software. Even the most well-designed user interfaces still have a learning curve, and you should be able to use existing manuals and resources to navigate the platform and adapt it to your needs easily.

Of course, you’ll inevitably need live customer support when integrating accounts payable automation platforms into your business ecosystem. Even if you can create a build that meets all your needs, you should still ensure that your service provider has live customer assistance standing by if you encounter any issues during initial phases or as you deploy the platform and operationalize your accounts payable workflows. 

These are the bare minimum requirements you should look for when sourcing an accounts payable automation solution. Beyond that, again, depends on your unique requirements – but these are some of the most important and common key features of AP automation software:

Document management

Your platform should easily sort, filter, and store invoicing, order documentation, and everything else you need to reference or pull in the future. This helps maintain compliance with industry-specific regulations and shields your business against potential audits. Comprehensive documentation management is also a best practice for firms in general. 

Invoice and vendor management

The software should integrate with your vendors and suppliers easily as part of your onboarding process. Afterward, the tools should help streamline invoicing and payments, manage contract terms, and keep tabs on how well your vendors meet those terms. If you use physical invoice processing, your tools should easily integrate scanned documentation while offering optical character recognition to prevent your staff from migrating information manually. 

Analytics – Offer strategic insight 

You should be able to pull depths of data and analytics into an easily digestible dashboard report complex enough to derive fresh insights while remaining simple enough to be actionable. 

Effective payment processing

The meat and potatoes of accounts payable software, the system should be a comprehensive, one-stop-shop for vendor payment. The tools should support the full spectrum of common payment methods like check, wire, and ACH, be easily integrated with your existing financial accounts, offer reliable scheduling and accurate reminders, and have manual approval options before funds disburse. If your business is global or has overseas vendors, you’ll also want to ensure the system facilitates cross-border payments. 

Workflow automation

Accounts payable automation tools aren’t much use if they don’t automate time-consuming tasks, right? Make sure the platform offers as many automation tools as possible to save your enterprise time and money, but with a specific eye towards:

  • Customizable workflows modifiable by purchase type, sourcing vendor, recurrence, amount, and more. 
  • Mobile options for remote approval and monitoring. 
  • Integrable collaboration for accounts payable staff and approving officials to modify and validate invoices quickly. 

Purchase order matching

A no-brainer: your accounts payable automation tool should automatically match purchase orders and receipts upon intake and execution while storing the same in an easily accessible format.

Let’s look at some of the best accounts payable software available in the market. We cover each software’s core offering, its top features, prominent user/customer profiles, and a guesstimate of its pricing.

Niche accounts payable software

Spend management software

Again, the “best” accounts payable tool is the one that fits within your business size and operational model most effectively. Still, if you’re beginning initial sourcing and platform due diligence, you’ll need to make sure a handful of basic, standard, and necessary features are part of the package.

Accounts payable process and accounting integration

Effective AP automation tools help optimize and streamline existing workflows. But you don’t want to be forced to adapt to a new accounts payable process if what you have works well. Remember, effective AP automation aims to save time and money by automating existing best practices – not forcing your firm to relearn an entirely new way of doing business. Likewise, the platform should adapt to your company’s accounting practices and standard operating procedures (SOPs) – not the other way around.  

On the other hand, you might be frustrated with an ineffective system and want to pivot to new processes. If you know that to be the case, you might want to use AP automation platform adoption as a springboard to begin a new workflow framework. If so, ensure the platform has plenty of digestible documentation and live support to help onboard your team, flatten the learning curve, and prevent frustration

Accurate (and useful) data capture and storage

You can’t manage what you don’t measure, and accurate data capture is the first step towards KPI management. If, for whatever reason, your invoicing formats aren’t standard across vendors (i.e., some are on paper, others via PDF, another in XML format, etc), you’ll need to make sure the AP automation platform easily integrates diverse sources while migrating data accurately. 

Depending on your security needs and scale, your platform should support the best document, data, and information storage. Whether cloud-based, via local hardware, or a combination, your AP automation tool should adapt to your needs and have the service personnel available to ensure security and document storage stability. 

Effective invoice management and payment processes

The top of the food chain – your managers and executives – are typically those tasked with final invoice approval authority. While this effectively controls spending, an ineffective approval workflow can waste their most precious commodity – time. An efficient AP automation tool should display all pertinent info in a simple dashboard for quick (and accurate) review and let approval authorities authorize invoices with a single click.

At the same time, though approval should be straightforward, those charged with maintaining accurate accounting need maximal visibility on the workflow. Your accounts payable and accounting team should have a granular look into an invoice’s progress and where holdups are. This helps ensure speedy delivery, of course but also serves to keep vendor and supplier invoicing relations on the right foot. 

Once routing is complete and approved, your platform of choice should disburse payments automatically and diligently log the transaction according to your SOP. 

Tax management integration

Tax integration, though it fits into the “accounting integration” category, deserves it’s own section. Effective accounting = proactive tax management and your AP automation tools ultimately feed your taxation cycle. Beyond other regulatory requirements, mismanaged taxes are one of the top pain points businesses face – and if your AP automation platform isn’t helping ease that burden, you’re better off finding an alternative.  


The use of Accounts Payable software or advanced invoice processing software comes with compelling benefits such as time and cost savings, streamlined accounts payable process, and ultimately better bottom lines.

Automated accounts payable solutions will enable human employees to concentrate on higher-value tasks such as business development that contribute to enterprise value.

The choice of an invoice to payment automation tool depends on the level of automation that the business requires, and the ability of the software to blend with the company’s practices and policies.
