How to Choose the Right Accounts Payable Automation Software
The best AP automation software for an organization is one that covers its accounts payable automation needs end to end. Here are some factors to consider before you decide on a solution:
Use of AI Technologies
Selecting, purchasing, and implementing an AP automation software can take weeks, if not months. With providers steadily incorporating AI into their solutions, it's important to choose a vendor that prioritizes AI to futureproof your AP function. Technologies like NLP, RAG, and AI-powered OCR are transforming how invoice data is extracted and leveraged for operational efficiency and better decision-making.
Test It on Your Worst Invoices
Rule-based and RPA-based tools struggle when invoice layouts change, which is why they often stall at partial automation. Ask each vendor to process 20 of your messiest invoices (multi-page, handwritten notes, new vendors) during the trial, and compare accuracy field by field.
Compatibility & Integration
Integration of your AP automation solution with existing ERP systems and financial software is crucial to ensure seamless AP operations. This requires checking the availability of relevant integrations and APIs for data exchange with third-party tools.
Learning Curve & Ease of Use
Some AP automation solutions have a steeper learning curve and may even require coding knowledge. When selecting automation software for your AP team, prioritize the expertise level of the end users: a solution that's challenging to use can create more problems than it solves.
Customer Support & User Reviews
Robust customer support is crucial for a long-term partnership with your AP automation vendor. It's important to check user reviews to understand a solution's upsides and drawbacks instead of relying solely on the product demo.
Customizability & Scalability
The solution should accommodate an increasing volume of invoices as your business grows. Discuss pricing plans and tiers for future needs to avoid vendor lock-in, and look for the ability to customize workflows, approval hierarchies, and reporting.
How AP automation software is priced
Most vendors use one of three models. Per invoice pricing suits teams with variable volume. Per user or seat pricing suits small AP teams that handle high volume. Platform subscription tiers are set by volume and features. Before you compare quotes, ask each vendor what counts as an invoice (pages or documents), whether ERP connectors cost extra, and what implementation support includes.
Closing
With AI transforming the accounts payable function, selecting the right automation software is about more than improving efficiency. It’s about setting up your organization for scalable growth and strengthened supplier relationships. Astera delivers end-to-end AP automation for a tenfold increase in efficiency and accuracy, while empowering users to extract relevant insights from their invoice data within seconds.
