The verdict in three sentences
For a private school under 400 students, a SaaS at 3-8 EUR/student/year stays the rational choice: nothing to host, updates included, a standard parent portal. Above 600 students, or when tuition billing, sibling discounts and agreements get complex, a custom-built system at 30,000-90,000 EUR excl. tax pays off within 3 to 5 years. The real trade-off is not the entry price but the 5-year total cost and control over your student data.
Education SaaS vs custom development: the 2026 comparison
SaaS vendors charge per student or per tier; custom is a one-off investment amortised over time. 2026 order of magnitude for a 600-student school.
| Criterion | Education SaaS | Custom-built |
|---|---|---|
| Upfront cost | 0-3,000 EUR (setup) | 30,000-90,000 EUR excl. tax |
| Annual cost | 3-8 EUR/student (1,800-4,800 EUR) | Maintenance 15-20% (5,000-14,000 EUR) |
| Time to launch | 2-6 weeks | 4-7 months |
| Parent portal | Standard, fixed | Custom, school-branded |
| Tuition billing | Fixed templates | Free sibling/scholarship rules |
| Data ownership | With the vendor | With you (GDPR control) |
| Export / reversibility | Often limited | Total |
What each module actually costs
A custom project is priced in lots. Here is an indicative breakdown for a primary + middle school.

|---|---|---|
| Online admissions | Application, documents, approval | 6,000-12,000 |
| Grades & reports | Entry, averages, PDF | 5,000-11,000 |

| Parent portal | Web + notifications | 6,000-14,000 |
| Online payment (card/SEPA) | Direct debits, receipts | 4,000-8,000 |

Marc, head of a 620-student private school in Toulouse, currently pays a SaaS at 6 EUR/student/year, i.e. 3,720 EUR/year, but juggles 3 spreadsheets for billing and loses 4 hours/week of admin time. A custom system at 48,000 EUR excl. tax, plus 8,000 EUR/year maintenance, replaces the SaaS and automates payment schedules. Admin savings: 4 h x 45 weeks x 28 EUR = 5,040 EUR/year. Net annual cost of custom: 8,000 - 3,720 (SaaS avoided) - 5,040 (time saved) = negative from year 2. The upfront investment is absorbed around year 3-4, plus an estimated 1-2 point cut in unpaid tuition.
FAQ
Is a SaaS enough for a small school? Yes, below 300-400 students the cost/benefit clearly favours SaaS: 3-8 EUR/student/year cover admissions, grades and the parent portal with no technical team.
How long to deploy a custom system? Plan 4 to 7 months depending on modules, ideally going live at the start of the school year to avoid a mid-year switch.
Who owns the student data? In custom builds it stays with you on your hosting (GDPR control); in SaaS it sits with the vendor, so check the reversibility clause and hosting location.
Can it connect to Pronote or ONDE? Yes, an import/export bridge is priced separately (2,000-6,000 EUR) depending on formats and sync frequency.
Is tuition billing really a differentiator? It is where custom wins most: sibling discounts, scholarships, tailored schedules and automatic reminders that generic SaaS handle poorly.
