What is accounts payable software?

Companies use accounts payable software to automate manual AP tasks like invoice entry, approval routing, and payment processing. This software cuts down on manual work, which improves accuracy and frees up your finance team for more important tasks. It connects smoothly with your ERP and accounting systems, ensuring information flows throughout your organization and making your entire business more efficient.

Reviews of the best accounts payable automation software tools

Each of our selected accounts payable automation tools brings unique strengths to the table. We've analyzed their key features, integration capabilities, pricing models, and ideal use cases to help you find the perfect match for your business requirements.

ApprovalMax

ApprovalMax is a cloud-based system that automates your bill-to-pay approval process from start to finish. ApprovalMax handles all the key steps in a single platform – from capturing bill data to making payments. It’s your one-stop-shop for stronger financial controls, improved cash flow and reduced manual effort.

Standout features

ApprovalMax Capture and ApprovalMax Pay: ApprovalMax Capture takes the hassle out of data entry by automatically extracting key details from invoices (Xero, QuickBooks and NetSuite) and purchase orders (Xero), before they have even reached your accounting system. This smart tool has bulk uploads and an email inbox for suppliers. And if you’re based in the UK (Xero), when you pair it with ApprovalMax Pay, you have a complete, secure payment system that can manage everything from inbox to payment in a single workflow.
Advanced, customisable multi-step approvals: ApprovalMax’s flexible approval matrix allows you to design approval workflows that reflect your organisation’s unique needs.
Editing on approval feature: If an approver spots a minor mistake, instead of sending the invoice back to the beginning of the process and starting the approval chain all over, you can edit the mistake right there and then.
Batch payment approvals: If you’re approving multiple invoices a day, you know how time-consuming the approval process can be. That’s why batch payment approval is so useful. Instead of approving one payment at a time, you can approve entire batches.
Budget Checking: Take the guesswork out of approvals with real-time budget information. Define budgets in Xero or QuickBooks and import them into ApprovalMax, where each bill and purchase order is checked against the available budget. If an approval exceeds the budget, approvers are alerted and can make informed decisions quickly.

Integrations: Xero, QuickBooks Online, NetSuite, Airwallex, Dext Prepare

Best for:

Mid-to-large businesses or growing enterprises
Organisations looking for an end-to-end AP automation solution with built-in OCR and Payments
Industries such as construction, healthcare, hospitality, and property development

Cons:

Limited integrations: ApprovalMax is not as feature rich as Xero and QuickBooks, something to keep in mind if your business relies heavily on ERP systems for enterprise resource planning solutions.
ApprovalMax Pay is only available for Xero UK businesses

Pricing:
ApprovalMax presents its pricing transparently on its website with a subscription-based model structured by user and feature tier. All the specifics, including per-user fees, volume discounts, and any add-on costs, are openly available on the pricing page, making it easy for organisations to choose the plan that best fits their needs. Plus, a 14-day free trial with no credit card required allows users to explore the platform before committing.

Supplier self-service portal: Suppliers onboard themselves, upload invoices, and update payment details, reducing AP team workload by up to 80%.

Cons:

Steep learning curve and complex interface: With so many features and options available through a single interface, new users can find themselves lost in a sea of settings and options.
Limited flexibility for non-enterprise workflows: Tipalti is enterprise-first software, which means that it’s great for large businesses, but not as flexible for smaller organisations.

Pricing:
Even though Tipalti mentions the rate for the starter pack ($99/month) on their website, Tipalti does not publicly disclose detailed pricing on its website, as costs are customised based on business size, transaction volume, and required features.

Occasional glitches: A few people have reported the odd sync problem or OCR goof-up, although these are usually quickly resolved with a little help from support. These minor glitches can still cause a short-term stop in your workflow.

Pricing:

Pricing:
The pricing of AvidXchange depends on what you need – how many invoices you process, how many steps you need in your workflow, what systems you need to integrate with, and the size of your organisation. Many of their customers report that the efficiency gains and improved cash flow more than make up for the cost, but you’ll need to get in touch to get a quote.
