Axentis - Attendance & Finance Platform

A comprehensive multi-tenant attendance and finance management platform designed specifically for extracurricular activities in Indonesian schools with role-based security, AI chatbot assistant, and real-time QR code scanning.

The Challenge

Indonesian schools struggle with fragmented extracurricular management—manual attendance tracking leads to inaccurate participation records, cash collection becomes chaotic with no transparent ledger, and communication between coaches and students relies on scattered WhatsApp groups. These inefficiencies create administrative burdens for teachers, distrust among parents regarding fund usage, and missed opportunities for student engagement tracking.
