What evidence would make you trust a pre-close billing-gap review?

Leakproof starts with two CSVs: contracts and invoices. It runs locally in the browser and surfaces potential missing-invoice or underbilling candidates with source-row evidence.

For finance teams: before you would use something like this during month-end close, what would you need to see? Examples: contract-line provenance, invoice-status handling, currency controls, reviewer sign-off, export format, or an audit log.

The demo is synthetic, and findings are review candidates—not claimed recovered revenue. I’m using the answers to shape the first design-partner workflow.
