Corithm School
K-12 School Management, Redefined
The most comprehensive K-12 operating system built for Indian schools — 552 database tables, 272 desktop screens, 273 mobile screens, a public REST API, a marketplace + parent wallet, a custom report builder with scheduled cron runs, and a white-labelled mobile app for every parent and student. Admissions to alumni. Geo-fenced attendance to GST-billed canteen. All on your hardware.
Powerful Features
Every feature is designed for Indian businesses — offline-first, privacy-hardened, and built for real-world use.
Geo-Fenced Attendance
Polygon-based geofencing + WiFi SSID validation ensures attendance is marked only from within school premises. GPS coordinates logged for audit, with full offline queue + sync.
Marketplace + Parent Wallet
Unified marketplace catalogue (uniforms, books, canteen, transport, events), cart + checkout via Razorpay, parent-funded wallet, refunds, and nightly payment reconciliation dashboard.
Dynamic Fee Management
Flexible fee structures (term / monthly / annual), discounts, scholarships, late-fee automation, Razorpay + PayU gateways, and full reconciliation against bank statements.
Custom Report Builder
Drag-and-drop canvas, multi-table joins, OR-grouped filters, pinned presets, run history with replay, and exports to CSV, PDF (Unicode/Hindi-safe) and Excel (.xlsx). Schedule any report to run via cron.
Public REST API + Webhooks
OpenAPI v1.8 with 11 scopes, 49+ endpoints (read + write + bulk import), API-key auth, rate limits, per-key audit logs, and 12 webhook event types with HMAC-SHA256 signing + retry circuit breaker.
DigiLocker + Admission Embed
Public web admission portal with DigiLocker document fetch, parent OTP verification, embeddable widgets for the school's own website, and full counselling workflow.
Live Classes
Bring-your-own-link Zoom / Teams sessions with attendance capture, plus Bunny Stream CDN relay for recordings and student-side replay — no separate streaming subscription required.
SMS, WhatsApp & FCM
Native integrations with MSG91, Twilio, Gupshup and Meta Cloud API + FCM push. Fee reminders, attendance alerts, exam notifications, circulars and marketplace order updates — all in 7 Indian languages.
Cron Daemon (Production)
Multi-tenant orchestrator (systemd + Docker) running scheduled report deliveries, nightly payment reconciliation, and tenant-isolated background jobs — POSIX cron syntax with smart next-fire computation.
White-Label Mobile App
Each school gets its own branded APK / AAB (iOS planned) with their logo, colours and identity — parents and students see the school's brand, never ours. Auto-update channel built in.
Driver Companion App
Dedicated mobile app for bus drivers — turn-by-turn route, stop-by-stop pickup confirmations, parent live-tracking, vehicle health logs and end-of-trip handover.
Payroll, HR & Audit Log UI
Full staff payroll with EPF, ESI, Professional Tax (18 states) and TDS. Leave, performance, recruitment — and a tamper-evident audit log UI for every sensitive action.

What Makes Us Different
552 database tables, 272 desktop screens and 273 mobile screens — covering every realistic school scenario, from meal nutrition tracking to exam hall seating to driver vehicle health logs. 17,256 automated tests keep it honest.
Geo-fenced attendance with polygon boundaries + WiFi SSID validation — the only K-12 system that physically verifies the attendance-taker's location, with full offline queue and conflict-safe sync.
A real public REST API (OpenAPI v1.8, 11 scopes, 49+ endpoints, HMAC-signed webhooks, per-key audit logs) — not an afterthought. Other school products give you exports; we give you an integration platform.
A full payments stack — Razorpay + PayU fee collection, a marketplace catalogue, parent-funded wallet, refunds, and an operator reconciliation dashboard backed by a nightly cron daemon. Most competitors only collect fees.
A custom report builder with drag-and-drop canvas, multi-table joins, OR-grouped filters, pinned presets, run history, scheduled cron delivery and Unicode-safe PDF/Excel exports — built in, not bolted on.
White-labelled branded mobile app for every school — your APK / AAB, your colours, your name on the parents' phone. Plus a dedicated driver companion app for the transport fleet.
