The verdict in three sentences
For a 1,300-pupil independent school in London, custom fee and school management software costs £45,000 to £90,000, delivered in 3 to 4 months. The main financial lever is the drop in overdue fees from 22% to 8% through online payment of instalments and automated SMS and email reminders. One-click PDF reports and grade tracking are a productivity bonus, but cash flow is what funds the project.
What the software must cover, from nursery to sixth form
A school running from nursery to sixth form handles very different realities: registration deposits, termly or monthly fees, lunches, transport, uniforms and exam entries. The software must therefore connect four blocks: the pupil record (family, class, history), teaching (grades, weightings, averages, reports), billing (schedule per family, sibling discounts) and collection (card, Direct Debit, Open Banking, bank transfer).
| Module | Concrete scope | Share of budget (2026 estimate) |
|---|---|---|
| Admissions and pupil records | Online application, documents, class allocation, siblings | £8,000 to £14,000 |
| Grades and PDF reports | Teacher entry, weightings, averages, signed reports | £11,000 to £22,000 |
| Fee schedule and billing | Instalments, lunches, transport, sibling discounts, receipts | £8,000 to £16,000 |
| Online payments | Card, Direct Debit and Open Banking links, automatic reconciliation | £7,000 to £15,000 |
| SMS and email reminders | D-3, D+5, D+15, escalation to the bursar | £4,000 to £8,000 |
| Parent portal | Balance, receipts, reports, absences on mobile | £7,000 to £15,000 |
| Total project | 3 to 4 months of delivery | £45,000 to £90,000 |
The low end covers a tight scope (one grading scheme, read-only parent portal). The high end includes several key stages with different grading schemes, an installable parent app and a financial dashboard for the head and bursar.
Running costs and market options
Cost does not stop at delivery. Budget for hosting, SMS, payment provider fees and maintenance. Card processing in the UK sits around 1.5% per transaction in 2026, Direct Debit providers charge roughly 1% capped per collection.
| Recurring item | Monthly amount 2026 | Note |
|---|---|---|
| Hosting and backups | £150 to £350 | Dedicated environment, daily backup |
| SMS reminders | £60 to £150 | About 1,300 families, 2 to 3 messages a month in reminder periods |
| Payment fees | About 1% to 1.5% of collections | Absorbed or passed on depending on school policy |
| Ongoing maintenance | £600 to £1,000 | Fixes, new fee scales, start-of-year changes |
| Off-the-shelf MIS licence (comparison) | £3 to £8 per pupil per year | Often modular, extra fees for parent apps |
Off-the-shelf school MIS products are cheaper upfront, but they impose their own report templates and often charge per pupil. A custom tool belongs to the school, with no per-pupil licence.
| Criterion | Off-the-shelf MIS | Custom build by Kolonell |
|---|---|---|
| Initial cost | £4,000 to £15,000 setup | £45,000 to £90,000 |
| Per-pupil licence | Common | None |
| Integrated online payments | Via add-ons | Yes, automatic reconciliation |
| Reports in the school's own format | Imposed templates | Exact school template |
| Time to go live | 2 to 4 weeks | 3 to 4 months |
| Changing fee scales | Depends on vendor | Unrestricted |
Mini case study
Mr Ndiaye, founder and head of an independent school in London, bills an average of £1,500 per pupil per term, so about £1,950,000 expected each term for 1,300 pupils. With 22% overdue, £429,000 per term is missing at the deadline. Bringing that rate down to 8% reduces the gap to £156,000, which means £273,000 collected on time each term. Over three terms, that is about £819,000 of improved cash flow. Even with an £80,000 project and £1,200 of monthly costs, the investment is covered within the first term of use. On top of that, about 60 hours of office time are saved each term on report production.

FAQ
How much does custom school management software cost in London in 2026?
Expect £45,000 to £90,000 depending on the number of key stages, modules and whether a parent app is included. Hosting adds £150 to £350 a month.
Can parents pay fees by card and Direct Debit?
Yes, each instalment generates a payment link and the receipt is issued automatically. Reconciliation happens without manual entry, which removes most bursary errors.
How do automated reminders reduce overdue fees?
A reminder 3 days before the due date, then at D+5 and D+15, settles most late payments. In equipped schools, overdue fees typically fall from 22% to 8%, a 2026 estimate.
How long until the system is live?
The project takes 3 to 4 months. Starting in April or May allows go-live for the September intake, with migration of existing pupil lists.
Is pupil data protected?
Access is role-based (head, bursar, teacher, parent) and data is processed in line with UK GDPR. Daily backups are included in hosting.
