KOSTIO
Manage. Bill. Retain.
Stop chasing rent payments by hand.
KOSTIO is a two-sided property management platform for kost owners. The owner dashboard handles billing cycles, tenant management, facility bookings, and support tickets. Tenants get a PWA they can install on their phone — self-service payments, complaints, and booking without calling anyone.
What it does
Automated Billing
Generate invoices for all tenants in one click. 3-stage reminder system (before-due, due, overdue) sent via Telegram or email automatically.
Tenant PWA
Tenants install KOSTIO on their phone like a native app. View bills, upload payment proof, submit tickets, and book facilities — all without a phone call.
Facility Booking
Owners define shared facilities (laundry, parking, meeting room). Tenants book time slots directly from the portal. Double-booking prevented automatically.
Contract Expiry Warnings
Dashboard alerts at 60, 30, and 0 days before contract ends — per tenant, with exact days remaining. No more surprise move-outs.
