The verdict in three sentences
Redesigning a West African banking group's corporate website costs in 2026 between 12 and 45 M FCFA (roughly EUR 18,300 to 68,600), depending on investor portal depth and security level. The realistic timeline is 12 to 18 weeks, with compliance and security QA weighing heavily. Then budget 200,000 to 800,000 FCFA/month for redundant hosting and 400,000 to 1.2 M FCFA/month for maintenance: a bank website is a trust asset, not a brochure.
What drives a bank's budget
A banking group does not buy a brochure site. It buys measurable trust: availability, security, compliance and content governance. Here is a 2026 order of magnitude for an EN + FR redesign, investor portal included.
| Line item | Share of budget | Range (FCFA) |
|---|---|---|
| Scoping, UX, current-site audit | 12% | 1.4 - 5.4 M |
| Art direction & design system | 16% | 1.9 - 7.2 M |
| Front-end + headless CMS build | 28% | 3.4 - 12.6 M |
| Hardened security (CSP, WAF, pentest) | 14% | 1.7 - 6.3 M |
| Investor portal & documents | 12% | 1.4 - 5.4 M |
| Multilingual (2nd / 3rd language) | 10% | 1.2 - 4.5 M |
| QA, compliance, accessibility | 8% | 1 - 3.6 M |
Hardened security is the sector-specific line: CSP headers, application firewall (WAF), penetration testing, fine-grained permissions and logging. It is non-negotiable for a regulated financial institution.
Redundant hosting and maintenance
A bank website cannot go down. Hosting must be redundant (multi-zone, automatic failover, encrypted backups) and maintenance must include monitoring and priority security patches.
| Service tier | Hosting / month | Maintenance / month | Target uptime |
|---|---|---|---|
| Standard | 200,000 FCFA | 400,000 FCFA | 99.5% |
| Hardened | 450,000 FCFA | 750,000 FCFA | 99.9% |
| Banking high-availability | 800,000 FCFA | 1.2 M FCFA | 99.95% |
| 24/7 on-call | +150,000 FCFA | +300,000 FCFA | + recovery < 1 h |
Over 3 years, a hardened configuration represents (450,000 + 750,000) x 36 = 43.2 M FCFA of recurring cost, often equal to the build cost. The board must see this full TCO, not just the upfront ticket.

Mini case study
Mr. Kone, communications director of a banking group in Miami serving Latin American markets (subsidiaries in 3 countries), leads an EN + ES redesign with an investor portal and ESG section. Accepted quote: 34 M FCFA build, redundant hosting at 550,000 FCFA/month, maintenance at 900,000 FCFA/month. 3-year TCO = 34,000,000 + (1,450,000 x 36) = 86.2 M FCFA. Set against brand image with institutional investors and fewer availability incidents (from 3 outages/year to zero), the board approves in one session on a smoothed monthly cost of 2.39 M FCFA.
FAQ
How much does a bank website redesign cost in 2026? Between 12 and 45 M FCFA depending on scope. An EN + FR redesign with an investor portal and hardened security lands around 28 to 38 M FCFA.
What timeline should I expect? From 12 to 18 weeks. Security QA and compliance sign-off add 2 to 4 weeks versus a standard corporate site.
What is hardened security? CSP headers, WAF application firewall, penetration testing, granular permissions and logging. It is about 14% of budget and essential in a regulated sector.
What annual recurring budget? A hardened configuration costs roughly 1.2 M FCFA/month combined (hosting + maintenance), i.e. 14.4 M FCFA/year. Over 3 years, recurring costs often equal the build cost.
Is the investor portal mandatory? No, but strongly recommended for a listed or growing group. It centralizes annual reports, press releases and regulatory documents, and represents 10 to 12% of budget.
