The verdict in three sentences
An off-the-shelf school solution (3-8 EUR/pupil/year) covers the essentials for a standard establishment, but a specific educational project benefits from owning its custom tool with a parent portal and online payment. Budget 40,000 to 100,000 EUR to manage enrolment, grades, family invoicing and communication in an integrated way. The ROI reads in two figures: -40 % administrative time and -25 % unpaid fees through automated reminders.
Off-the-shelf solution or custom software
A SaaS school-life tool is often enough for a classic secondary school. A school group, a bilingual school or an establishment with complex invoicing (instalment plans, scholarships, paid options) will quickly hit the limits of the standard.
| Criterion | Off-the-shelf solution | Custom software |
|---|---|---|
| Upfront cost | 500 to 3,000 EUR | 40,000 to 100,000 EUR |
| Recurring cost | 3-8 EUR/pupil/year | Hosting 100-400 EUR/month |
| Parent portal | Standard | Tailored to your pedagogy |
| Online payment | Often optional | Integrated (card, direct debit) |
| Family invoicing | Fixed model | Instalments, scholarships, options |
| Timetable | External import | Integrated generation |
| Data ownership | No | Yes |
For an 800-pupil establishment, a solution at 6 EUR/pupil/year represents 4,800 EUR/year — moderate, but without owning the tool or being able to adapt it to an atypical operation.
The real gain: administrative time and unpaid fees
In private education, two items weigh heavily: office staff time and the family default rate. Here is the 2026 order of magnitude for an 800-pupil establishment, tuition 3,500 EUR/year.
| Lever | 2026 situation | Estimated annual gain |
|---|---|---|
| Administrative time | -40 % on enrolment/invoicing | 0.8 to 1.2 FTE, i.e. 25,000 to 40,000 EUR |
| Family unpaid fees | -25 % via auto reminders | 30,000 to 50,000 EUR of cash recovered |
| Online payment | +30 % collected within 15 days | More regular cash flow |
| Centralised communication | -60 % manual emails | 0.3 FTE relieved |
Mini case study
Mr Bernard, director of a private school group in Lille (800 pupils, two sites), manages enrolment in a spreadsheet and suffers 9 % unpaid fees. He invests 68,000 EUR in custom software: parent portal, online payment, invoicing with instalment plans, automated reminders. Within a year, office time drops 40 % (1 FTE relieved, ~32,000 EUR) and unpaid fees fall to 6.5 % (28,000 EUR recovered). Annual gain: 60,000 EUR, payback in 14 months.
FAQ

Isn't an off-the-shelf solution enough for a standard school?
If your operation is classic, yes. But as soon as invoicing gets complex (scholarships, options, instalments, two sites) or you want a branded parent portal, custom avoids costly workarounds.
Is online family payment included?
In a custom project, yes: card and SEPA direct debit integrated, with automatic instalment plans. This module represents 8,000 to 15,000 EUR but sharply reduces unpaid fees.
Do parents really adopt the portal?
When the portal centralises grades, absences, invoices and payment in one place, the usage rate often exceeds 80 % from the first term. The key is a simple mobile interface.
How long to be operational before the new school year?
Budget 4 to 6 months. Starting in spring, invoicing and enrolment are ready for September; pedagogical modules follow during the year.
What annual maintenance cost?
Between 12 and 18 % of development, i.e. 8,000 to 15,000 EUR for a 70,000 EUR project, including regulatory updates and GDPR-compliant hosting.
