The verdict in three sentences
A banking corporate redesign is not a showcase site: it is a project of content governance, compliance and security whose realistic 2026 budget runs from 25M to 60M FCFA (38,000-91,000 EUR). The multi-level validation workflow, the security audit and WCAG 2.1 AA accessibility alone account for roughly 25% of the envelope. Expect a dedicated project manager, agile sprints and 16-24 weeks with weekly reviews.
Budget breakdown
In a banking project, more than half the cost is not design but compliance, security and integration.
| Item | Budget share | Range (60M FCFA) |
|---|---|---|
| Design and UX | 20% | 12M FCFA |
| Front/back development | 30% | 18M FCFA |
| Security (CSP, audit, pentest) | 15% | 9M FCFA |
| Governance and editorial workflow | 10% | 6M FCFA |
| WCAG 2.1 AA accessibility | 8% | 4.8M FCFA |
| Investor relations space | 10% | 6M FCFA |
| Project management and acceptance | 7% | 4.2M FCFA |
A seasoned CIO's reflex: never cut the security audit or the validation workflow. They are what prevent an unauthorized publication or a regulatory breach.
Non-negotiable requirements 2026
A banking site faces obligations an SME does not. Each line below is an acceptance criterion.
| Requirement | Level required | Timeline impact |
|---|---|---|
| CSP and security headers | Strict, no inline | +1-2 weeks |
| WCAG 2.1 AA | External audit included | +2-3 weeks |
| Validation workflow | 3 levels minimum | +2 weeks |
| Multilingual | EN + FR (sometimes Arabic RTL) | +2-4 weeks |
| Data compliance | GDPR + local law | +1-2 weeks |
| SLA and uptime | 99.9%, 24/7 monitoring | ongoing |
| Investor space | Documents, share price, results | +3-4 weeks |
The sum of these requirements explains the timeline gap with a standard site: 16-24 weeks, not 6.
Mini case study
Mr. Kone, communications director of a banking group in Dubai, leads the redesign of the corporate site and investor space. Scope: 45 pages, EN + FR, a 3-level workflow, WCAG audit and pentest. Approved budget: 48M FCFA (73,000 EUR), 20 weeks. Security and governance account for 12M FCFA. Result: AA compliance validated by external audit, press-release publishing time cut from 3 days to 4 hours thanks to the workflow, and an investor space available in 2 languages. The editorial responsiveness gain frees the equivalent of a half-time role in the comms team.

FAQ
Why does a banking site cost so much?
Design is only 20%. The rest goes to security, compliance, accessibility and governance: about 25% of the budget just for the workflow and security audit. These are obligations, not options.
Is WCAG 2.1 AA really mandatory?
For an institutional actor, yes. It governs legal accessibility and brand image. The external audit adds 2-3 weeks but secures acceptance.
How long does the project take?
Expect 16-24 weeks in sprints with weekly reviews and a dedicated project manager. Security and validation requirements explain the duration.
Can you handle 3 languages including Arabic?
Yes, with RTL support. Each extra language adds 2-4 weeks plus translation and linguistic acceptance costs.
What minimum budget should we target?
Below 25M FCFA (38,000 EUR) you cannot properly cover security, compliance and governance. The realistic threshold for a banking group starts there.
