The verdict in three sentences
For a 900-student private school, a vertical solution at 8-15 EUR/student/year covers the essentials cheaply and without an IT team. Custom student-management software (40,000-65,000 EUR one-off + 15% annual maintenance) only pays off when tuition billing, a parent portal and specific workflows save 10 hours/week of admin. Under 1,000 students with standard needs, vertical wins; custom targets multi-campus groups with atypical rules, breaking even near 30 months.
Vertical vs custom: 2026 comparison
| Criterion | Vertical solution | Custom |
|---|---|---|
| Entry price | 8-15 EUR/student/year | 40,000-65,000 EUR one-off |
| Cost 900 students/year | 7,200-13,500 EUR | 15%/year maintenance |
| Parent portal | Standard | Custom |
| Tuition billing | Basic | Advanced (schedules, reminders) |
| Specific workflows | No | Yes |
| Rollout | 2-6 weeks | 14-20 weeks |
| Minors' data compliance | Vendor-compliant | Full control |
| Data ownership | Vendor | You |
5-year TCO
| Item | Vertical 900 students | Custom |
|---|---|---|
| License / build | 50,000 EUR (5 yrs, ~10k/yr) | 52,000 EUR |
| Accounting + payment integration | 3,000 EUR | included |
| Maintenance | included | 39,000 EUR (5 x 7,800) |
| GDPR hosting (Scaleway) | n/a | 4,200 EUR (5 yrs) |
| Admin team training | 2,000 EUR | 3,000 EUR |
| 5-year total | ~55,000 EUR | ~98,200 EUR |
At 900 students, vertical stays nearly half the price. Custom only repays through recovered admin time and needs the vendor cannot cover (multi-campus, complex billing, specific portal).
Priority student / billing modules
| Module | Estimated gain | Priority |
|---|---|---|
| Automated tuition billing | 10 hours/week | High |
| Parent portal (grades, absences, payment) | -calls/emails | High |
| Automatic overdue reminders | -25% late payments | High |
| Enrollment management | -double entry | Medium |
| Timetables / rooms | Optimization | Medium |
| Minors' data vault | Compliance | High |

Mini case study
Mr. Ferrand, director of a Montreal private school group (900 students, 2 campuses), sees his admin team spend 10 hours/week on tuition billing and manual reminders. At 28 EUR/hour loaded over 40 weeks, that is ~11,200 EUR/year. A custom build at 52,000 EUR + 7,800 EUR/year maintenance automates 8 hours/week (~9,000 EUR/year) and cuts overdue payments by 25% (on ~180,000 EUR of arrears, that accelerates ~45,000 EUR of cash). Crediting time savings plus a 6% cost of cash, payback lands near 30 months.
