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
