RefineTrain AI

RefineTrain AI is an invoice validation service that uses AI agents to check invoices against the contracts and records behind them. It targets complex industries such as construction, where layered contracts, change orders, approvals and prior spend make manual checking slow and error prone. The workflow has three steps. First the system ingests contracts, emails and other documents, cross checks vendor obligations, and builds a knowledge graph of requirements. Then it validates invoice line items against that graph and pulls data such as approvals from connected internal systems. Finally it flags problems with clear reasoning and quoted evidence. The process is designed for human review rather than hands off automation, so only high risk invoices reach a person. The vendor says its agents handle checks that take around 20 steps across several documents, systems and linked contract clauses without pre programming. It is aimed at finance, legal and operations teams that lose time reconciling invoices, risk overpaying or paying twice, and want an alternative to outsourced processing that raises data leakage concerns. The company is accepting three companies into a pilot. Implementation fees are waived during the pilot, and pilot participants are promised grandfathered, discounted pricing afterward. An Enterprise tier with custom integrations, dedicated onboarding, SLA and security reviews is marked coming soon. No price figures are published.
