About

ClientGuard is a customer concentration check for agencies, consultancies and other service businesses. Upload revenue by client exported from QuickBooks, Xero, FreshBooks or a spreadsheet, and within seconds you see a risk score from 0 to 100 and your three largest clients, with no email needed. Any single client above 25 percent of revenue is flagged red. Files are processed in memory and not stored, and a calculator in the browser works with typed figures too.The full audit costs 39 USD once and arrives by email within a minute: the top 10 clients ranked and flagged, the Herfindahl-Hirschman Index, a benchmark and a 12-step plan based on your numbers, covering retainer terms, pipeline targets and more.
