1
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.

ApprovalMax AP automation solution results

Standout features

  • ApprovalMax Capture and ApprovalMax Pay: ApprovalMax Capture takes the hassle out of data entry by automatically extracting key details from invoices (Xero, QBO 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 QBO 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 QBO, 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.

Integrations: NetSuite, Sage, Microsoft Dynamics 365, Quickbooks, Acumatica, Xero, SAP

Best for:

  • Global enterprises with suppliers in multiple countries
  • High-growth companies processing 1,000+ invoices/month
  • Industries like e-commerce, SaaS, and media with complex payment needs

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.
