How it works
Confirmed attendance in, disputed invoices out.
The month-end argument disappears because the client already approved every duty, day by day.
01Guards check in from siteGeofenced check-in on the mobile app, with a printed site-QR fallback. Works offline and syncs when back online.
02Clients confirm on WhatsAppA daily digest goes to the client SPOC. One tap approves the day — or flags an exception. Silence auto-confirms after the agreed window.
03Reconcile & lock the cycleEvery day resolved, the billing cycle locks. No more editing history behind an invoice.
04Invoice, collect, postGST invoice (incl. RCM) generated from confirmed duties, delivered on WhatsApp, and auto-posted to receivables and the ledger.
