The Journey
From challenge to solution
The Challenge
GLS Sprachenzentrum ran its centers with scattered tools: paper attendance sheets, manual payroll, unpaid fees tracked in spreadsheets and a website unable to qualify enrollment requests. It needed both a conversion-focused bilingual public website and a full back office to manage groups, teachers, CRM, payroll and physical access, center by center.
- Attendance, schedules and payroll handled manually, with no consolidated view
- Website unable to qualify or convert enrollment requests
- No data segmented by center, and no reliable tracking of unpaid fees
Our Solution
We delivered a single platform with two areas: a bilingual FR/EN front office showcasing levels, courses and centers with optimized lead capture (enrollment, level quiz, certificate verification), and a permission-based back office covering student CRM, automated payroll, payment collection and Hikvision access control. Explore our solution for language schools.
- Bilingual website with a level quiz, online enrollment and QR code certificate verification
- Full student CRM: attendance, payments, collections and churn score
- Automated payroll from attendance imports, with bonuses and an audit trail
- Native Hikvision physical access control and weekly teaching reports
