The verdict in three sentences
For a single school under 400 pupils, a market education tool (EcoleDirecte, Skolengo, Charlemagne) is unbeatable on price and covers 80% of needs. For a school group or a school with specific processes (multi-currency billing, custom parent portal, multiple campuses), a build at 35,000-100,000 EUR excl. VAT removes re-keying and smooths enrolment and payments. The real gain isn't functional but administrative: dozens of hours per month handed back to the office.
Education tools or custom: the comparison
A school stacks schooling software, billing, parent portal, academic tracking and sometimes an enrolment CRM. Market tools are solid on the school core but rigid on billing and the portal. Custom targets the parent experience and admin automation.
| Criterion | Market education tool | Custom Kolonell |
|---|---|---|
| Upfront cost | 1,500-6,000 EUR excl. VAT (setup) | 35,000-100,000 EUR excl. VAT |
| Recurring cost | 3-8 EUR/pupil/year | Hosting 250-700 EUR/month |
| Parent portal | Standard, little customization | Custom, school-branded |
| Fee billing | Basic | Schedules, reminders, multi-currency |
| Online payment | Limited add-on | Card, direct debit, Wave/OM (Africa) |
| Academic tracking | Complete | Custom or integrated |
| Time to deploy | 2-8 weeks | 3-5 months |
For an 800-pupil school at 6 EUR/pupil/year, the licence is modest (4,800 EUR excl. VAT/year). So custom isn't justified by licence savings but by recovered admin time and the enrolment experience.
Where custom really pays
The parent portal and fee billing are the two points where generic tools frustrate. Manual reminders, rigid schedules, offline payments reconciled by hand: hours lost every month.
| Admin task | Without custom | With custom |
|---|---|---|
| Chasing unpaid fees | Manual, mail | Automatic, email/SMS |
| Fee schedule | Fixed | Personalized per family |
| Payment reconciliation | Manual entry | Automatic |
| Enrolment file | Paper + re-keying | Online, zero re-keying |
| Certificates and receipts | Manual editing | Generated in 1 click |
An assistant spending 12 hours/week on reminders and reconciliation, at a loaded cost of about 28 EUR excl. VAT/hour, is nearly 17,000 EUR excl. VAT/year of time. Cutting that load 70% frees 12,000 EUR excl. VAT/year, reassigned to welcoming families.

Mini case study
Sister Marie-Claire, head of a private school group of 1,200 pupils across 2 campuses, runs billing on a spreadsheet and a generic schooling tool. Two people dedicate the equivalent of 1.5 FTE to billing, reminders and payment reconciliation, about 58,000 EUR excl. VAT/year. A custom parent portal and billing engine priced at 72,000 EUR excl. VAT automate reminders, schedules and online payments, cutting the load 40%, saving 23,000 EUR excl. VAT/year. Payback: about 3 years, with a jump in family satisfaction.
FAQ
Must we drop our current schooling software? Not necessarily. We often keep the academic core (grades, attendance) and build only the parent portal and billing custom, connected via API: cost drops to 35,000-55,000 EUR excl. VAT.
Does custom handle online payments? Yes: card and SEPA direct debit in France, and Wave/Orange Money for schools in West Africa. Reconciliation becomes automatic, removing manual matching.
How long to digitize enrolment? An online enrolment module with paperless files ships in 6-10 weeks. It removes re-keying and shortens enrolment by several days.
What recurring budget? Budget 250 to 700 EUR excl. VAT/month hosting and a maintenance retainer of 500-1,500 EUR excl. VAT/month. Well below the admin time saved.
Is it worth it for a single school? Rarely below 400-500 pupils. Custom becomes relevant for multi-campus groups or schools with complex billing (scholarships, schedules, multiple currencies).
