FAQs about Invoice Verification Software

Invoice verification software is a tool that checks invoices against contract requirements and required documents before approval. It helps teams catch missing, expired, or non-compliant items faster.
Invoice validation software is useful for project managers, contract administrators, commercial teams, cost managers, and project controls teams who review contractor or consultant invoices.
Mastt uses AI Compliance to extract payment-related requirements from a contract PDF, then checks an uploaded invoice PDF against those requirements. Reviewers can then open the AI Review tab, view the result for each compliance item, and manually update any status if needed.
Mastt can show statuses including Pending, Accepted, Needs Review, Not Applicable, Missing, Rejected, and Expired. These statuses help reviewers understand which documents are complete, which items are unclear, and which requirements still need action before approval.
Contracts and invoices must be uploaded as PDFs for AI Compliance and AI Review. If your source file is in another format, it needs to be converted to PDF before upload.
Yes. Mastt allows reviewers to check the AI recommendation, read the supporting reasoning, and manually override the status during review.
AI Review usually takes about 1 to 3 minutes, depending on document complexity and the number of checklist items. That gives teams a faster first-pass review without removing human oversight from the payment process.
