The verdict in three sentences
For a London private school, management software is first an administrative-load reducer, not a cost centre. A school SaaS bills 3 to 8 EUR per pupil per year, while a custom build costs 40,000 to 100,000 EUR. The choice depends on pupil count, curriculum complexity and the need for a parent portal and integrated payment.
School SaaS or custom platform
A school of 400 to 1,200 pupils has different constraints from a single 150-pupil site. Here are 2026 orders of magnitude.
| Item | School SaaS | Custom platform |
|---|---|---|
| Entry cost | 0 to 3,000 EUR setup | 40,000 to 100,000 EUR |
| Recurring cost | 3 to 8 EUR/pupil/year | 500 to 1,500 EUR/month (hosting + maintenance) |
| For 800 pupils | 2,400 to 6,400 EUR/year | maintenance in recurring |
| Curriculum customisation | limited | full |
| Data ownership | vendor | school |
| Timeline | 3 to 6 weeks | 4 to 7 months |
| Parent portal included | often optional | integrated |
At 800 pupils, SaaS costs 2,400 to 6,400 EUR per year, with no heavy investment. Custom is justified for a multi-site network or atypical curricula (bilingual, work-study) poorly covered by vendors.
Modules and compliance
The core (admissions, grades, attendance) is standard; parent and payment modules create the comfort and the savings.
| Module | 2026 range (custom) | Main benefit |
|---|---|---|
| Parent portal (grades, attendance, messaging) | +8,000 to 20,000 EUR | -60 % calls to the office |
| Online tuition payment | +5,000 to 12,000 EUR | cash flow, fewer arrears |
| Online admissions / re-enrolment | +6,000 to 14,000 EUR | -60 % file admin |
| Timetable & rooms | +5,000 to 11,000 EUR | automated scheduling |
| Billing & automatic reminders | +4,000 to 9,000 EUR | reliable collection |
| GDPR compliance for minors' data | +3,000 to 7,000 EUR | legal safety |

Mini case study
Mr Berger runs a London private school of 780 pupils. Each admission campaign mobilises 2 administrators for ~6 weeks, entry and reminders included, i.e. about 480 hours of processing at ~28 EUR loaded cost, or ~13,400 EUR per year. By deploying an online admissions module with parent portal and integrated payment for 58,000 EUR, he removes ~60 % of that load, i.e. ~8,000 EUR saved per year in admin time, and reclaims 2 to 3 weeks of lead time. Adding reduced arrears (online payment cutting delays by 20 %), the return becomes tangible by the second intake.
FAQ
How much is a school SaaS for 800 pupils? Expect 3 to 8 EUR per pupil per year, i.e. 2,400 to 6,400 EUR annually, with parent portal and payment often billed as options.
When to move to custom? As soon as you run several sites, specific curricula or want full data ownership: custom at 40,000-100,000 EUR pays back over 3 to 5 years.
Does the parent portal really cut office workload? Yes, by giving direct access to grades, attendance and payments: a 50 to 60 % drop in inbound calls is common after rollout.
Is online tuition payment secure and compliant? Yes, via PCI-DSS certified providers and GDPR handling of minors' data; count +5,000 to 12,000 EUR for the module.
How long for a full custom platform? Between 4 and 7 months, aiming for go-live before an admission campaign to maximise the gain from the first intake.
