Compare the top six invoice processing software providers in New Zealand 2025

Managing supplier payments is a critical part of running a smooth business operation. Yet, for many businesses, processing a high volume of invoices can be a headache.

If you’re looking to streamline your accounts payable process, improve visibility over your company’s spend, and save your finance team hours of time data entry – invoice processing software is the answer.

Let’s take a look into the top six invoice processing software providers available in New Zealand in 2025 to get a clear picture of the options for your business.

What is invoice processing software?

Invoice processing systems are software tools designed to handle invoices and streamline the accounts payable process for businesses. The top invoice processing software minimises manual data entry and reduces human errors, enhancing efficiency, speeding up payment cycles, and improving vendor relationships.

Other features of automated invoice processing systems include automated data extraction, invoice validation and approval workflows, and bill payment error flagging. Robust controls and approval processes can help ‌boost company spend compliance.

Many invoice processing solutions integrate with existing accounting software systems to provide real-time spend visibility and reporting capabilities. The best invoice processing software will include a full suite of spend management tools, allowing you to process invoices and track, manage, and control your global spend from a centralised location.

How does an invoice processing software system work?

Think about how your team currently handles invoice processing. Do they use one system for uploading and tracking invoices, then another for internal approvals? Once approved, are they then having to switch back to the banking system to pay the invoice, before finally manually reconciling everything in your business's accounting software?

Invoice processing software works by bringing these processes together. With the right invoice processing software, you’ll be less likely to miss payment deadlines and lose control of your cash flow, and more likely to find the reconciliation process much smoother.

Here’s how it generally works;

1. Bills are uploaded and invoice information entered into the invoice processing system. The best invoicing process software on offer will enable you to do this either via direct upload or simply emailing the bills to a certain address. All relevant invoice data will then be automatically captured and recorded in the system using Optical Character Recognition (OCR) technology.

2. Invoice details are verified against Purchase Orders, and then routed through to approval. The top invoice processing software will allow a multi-layer custom-designed approval workflow tailored to your business needs.

3. Once approved, the invoice is queued for payment. Many companies still do this on an external banking system, separate from their invoice processing software. However, unified platforms are now available, which combine software with financial infrastructure, allowing for direct bill payments within the same system. 

4. Paid bills are then reconciled in accounting software against invoices and purchase orders. In many cases, this is a manual and time-consuming process. However, top providers will have integrations that will automatically sync paid bills to your accounting software.

5. Finally, you’re able to draw unique and useful insights from your invoice processing software to be able to understand your company's spend and identify areas for improvement.
