Compare invoices with orders, hold duplicates, chase approvals. Every one is ready to run, and you can adjust it in plain language.
Your bill reviewers get the supplier invoice and any mismatches together before they decide what to approve.
Your policy owner gets a private alert when a purchase request breaks your spend rules, so they can choose the next reviewer.
Your reviewers see what changed since the last approval and get the revised order for a fresh decision.
Your AP reviewer sees a possible duplicate and its earlier invoice before approval or payment.
