Define your requirements before comparing scores.
A team looking to reduce invoice entry has a different requirement from a team trying to resolve non-PO coding, manage procurement or improve collections. Start with a short description of the work, its volume, the systems involved and the exceptions that consume time.
The questions below are an evaluation framework. They are not claims that every product in a category behaves the same way.
1. Which steps does the platform complete?
Ask the vendor to follow one transaction from arrival through to the final ERP record. Separate document capture, validation, coding, matching, approval and payment. For each step, identify who or what takes the action.
Include an exception in the walkthrough: a missing purchase order, a price variance or an unfamiliar supplier. A demonstration of a clean invoice does not establish how the product handles your difficult cases.
2. How does the record get into your ERP?
Request the integration architecture for your exact ERP and release. Identify the system that holds the final record, the supported interface used to create it and how errors are reported.
Ask about timing, duplicate prevention and recovery after a failed transfer. A file-based process and a real-time API may have different operational requirements; evaluate those requirements against your own controls and workload.
3. Who owns the business rules?
Use a real example, such as a freight charge that needs a different account or a supplier-specific approval rule. Ask who changes that rule, who approves the change and when it takes effect.
If the provider says the system learns from corrections, request a demonstration of how a correction is reviewed, recorded and applied. Establish how an incorrect change can be reversed.
4. What remains under your control?
Ask for the roles and permissions required by the integration, the approval boundaries and the records retained for review. Establish how access is revoked and how a completed action can be traced to its source document.
Request the security and data-handling documentation that your organisation needs. Treat a badge or a brief feature description as the start of that conversation.
5. What do the performance numbers actually measure?
For a quoted automation or accuracy rate, request the definition, measurement period, sample size, workflow scope and excluded cases. Ask whether the result describes capture, coding, approval or the entire transaction.
A named reference is more useful when its environment resembles yours. Compare ERP version, document mix, volume and implementation scope before treating a result as a forecast.
6. Who owns implementation and ongoing maintenance?
Ask for a plan that separates vendor work, your IT work and finance-team involvement. Include access setup, mappings, rule configuration, acceptance criteria, training and support after launch.
Confirm what happens when your ERP changes, a supplier introduces a new document format or an integration fails. Compare ongoing ownership and total cost alongside the software subscription.
