The verdict in three sentences
For 14,000 applications a year, a custom online registration platform removes queues, secures exam fee collection and cuts application processing time by two thirds. Kolonell's budget sits in the medium range, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), moving to the complex range if you add marking, deliberation or links to other systems. Timeline is 3 to 5 months, and it must be locked in before the application window opens.
The hidden cost of paper applications
A paper exam campaign ties up staff for 6 to 8 weeks: receiving files, checking documents, data entry, collecting fees in cash or via bank slips, printing admission slips, then posting results on boards that draw crowds. Applicants from remote regions sometimes travel 600 km just to submit a file.
| Step | Paper campaign | Online platform | Measurable effect |
|---|---|---|---|
| Submission | Counter, 2 to 4 h wait | 15-minute form from a phone | No travel |
| Supporting documents | Certified photocopies | PDF scans or photos, format checks | Incomplete files flagged instantly |
| Exam fees | Cash or bank slip | Wave, Orange Money, card | Automatic reconciliation |
| Review | 3 staff for 6 weeks | Validation screen, rejection reasons | Processing cut by two thirds |
| Admission slips | Printing and posting | PDF with QR code, by email and SMS | ID check on exam day |
| Results | Notice boards, crowds, copying errors | Secure lookup by candidate number and birth date | Zero copying errors |
Architecture and sizing for peaks
The real technical challenge is load: registrations pile up in the final days, and results day can generate 3,000 logins per hour, more in the minutes after the announcement. The platform must be sized for that peak, with lightweight pages that work on 3G and caching on public pages.
| Component | Role | Complexity | Critical point |
|---|---|---|---|
| Applicant area | Account, form, application tracking | Medium | Mobile usability, autosave |
| Document upload | PDF or image upload, compression | Medium | 5 MB per file cap, encrypted storage |
| Payment | Fees of 10,000 to 25,000 FCFA | Medium | Wave and Orange Money webhooks, automatic receipts |
| Panel back office | Approve, reject with reason, statistics | Medium | Roles and audit trail |
| Admission slips | Batch PDF generation with QR code | Low to medium | 14,000 PDFs in under an hour |
| Results | Scheduled publication, individual access | Medium | Load handling, anti-scraping protection |
| Hosting | Servers and backups | Quoted separately | Elastic capacity during peaks |
Data protection compliance is built into scoping: explicit consent, retention periods for documents, and registration with the national data protection authority (in Senegal, the CDP under law 2008-12). Applicant data is used only for the exam.
Recommended calendar
For applications opening in March, the project should start in October or November: 3 weeks of scoping with the academic office and finance, 8 to 10 weeks of development, 3 weeks of acceptance testing with a mock exam, then a pilot on a single programme if the calendar allows. A late start forces last-minute feature cuts that cost more the following year.
Mini case study
Mrs. Sarr, director of studies at a public school in Dakar, receives 14,000 applications at an average 15,000 FCFA fee, i.e. 210,000,000 FCFA collected per campaign. On paper, the campaign uses 3 staff for 6 weeks plus 2 cashiers for 4 weeks, about 26 staff-weeks. With the platform, one reviewer for 6 weeks remains: 20 staff-weeks freed.
Add avoided cash discrepancies, printing of admission slips (14,000 sheets plus posting), and above all wider access: if going online brings 10% more applicants from the regions, i.e. 1,400 files, fee income rises by 21,000,000 FCFA. With a 6,000,000 FCFA platform budget, the extra applications alone cover the investment in the first campaign, before payment operator fees.

Experience from comparable schools shows the second campaign is where the platform really pays off: templates, rejection reasons and the fee grid are reused, and staff training drops to a single half-day session.
FAQ
Will the platform survive results day?
Yes, if it is sized for that peak: light results pages, caching, a queue if needed. We load-test at least 3,000 logins per hour, or double your observed peak if you prefer.
How are exam fees collected?
Via Wave, Orange Money or bank card, with an automatic receipt. The application switches to paid as soon as the operator confirms, removing manual reconciliation across 14,000 payments.
What about applicants without internet or a smartphone?
A help desk can be set up at the school or partner locations. In comparable campaigns, over 90% of applicants register on their own from a phone.
Could results leak before official publication?
No, publication is scheduled and approved by two officials, and access requires a candidate number and birth date. Every lookup is logged.
What does it cost after launch?
Kolonell maintenance is 35,000, 75,000 or 120,000 FCFA per month. The 75,000 FCFA level is usually enough outside campaigns; reinforced hosting during peaks is quoted separately.
