DALLAS - s4story -- Lanawrai Holdings LLC today released the Margin Sentinel free leak scan, a browser-based tool that helps small businesses find money leaking from their bank and card accounts. A business drops in the CSV file its bank already provides, and the scan checks every line for four kinds of leaks: duplicate charges, quiet subscription price increases, bank and card fees, and impostor payees that mimic real vendors. Each finding comes with the amount at stake and what to do about it. The scan runs entirely in the visitor's own browser — financial statements are never uploaded to Lanawrai's servers. In testing, the scan passed 206 of 206 functional verification tests and 206 of 206 data-variety scenarios, run against the exact file served on the site; on the tool's built-in sample statement it found $3,967 per year in leaks. The scan is free. Ongoing monitoring through Margin Sentinel starts at $79 per month for a single business, with a guarantee: if it doesn't find at least three times the yearly fee in savings, the fee is refunded. Bookkeepers and accountants can run it across their client book for $25 per client per month. 'Small businesses lose money in ways that never show up as a line item,' said Benny Daniel, founder of Lanawrai Holdings LLC. 'A duplicate charge here, a quiet price increase there — Margin Sentinel reads every line so owners can see it and stop it.' The free scan and a 30-second explainer video are at https://lanawraiholdings.com/margin-sentinel.
