The verdict in three sentences
A packaged CMS (WordPress, Drupal) offers the best time-to-market and an entry cost of EUR 15,000-35,000, ideal for a standard editorial site. A custom build (EUR 40,000-80,000) is justified when security, business integrations and full control outweigh speed. In 2026, a CIO decides on total cost over 3 years, not the headline entry price.
Acquisition cost and licences 2026
| Item | Packaged CMS | Custom build |
|---|---|---|
| Initial build | EUR 15,000-35,000 | EUR 40,000-80,000 |
| Licences/plugins per year | EUR 500-2,500 | EUR 0-500 |
| Time-to-market | 6-10 weeks | 14-24 weeks |
| Skills required | Broad, available | Rare, senior |
| Deep customisation | Limited | Total |
| Vendor dependency | Moderate | Low |
The CMS costs less upfront but accumulates annual licences and plugins. The custom build reverses the curve: expensive at first, light thereafter.
Security, scalability and vendor lock-in
| Criterion | Packaged CMS | Custom build |
|---|---|---|
| Attack surface | High (third-party plugins) | Reduced |
| Patch frequency | Weekly | On demand |
| Functional scalability | Good if standard | Unlimited |
| Vendor lock-in | Moderate | Low but proprietary code |
| GDPR/accessibility compliance | To configure | Native if specified |
| Maintenance load | Medium | Heavier at first |
A CMS multiplies third-party plugins, hence the attack surface. A custom build cuts that risk but concentrates knowledge with the provider.
Total cost over 3 years (2026 order of magnitude)
| Scenario | Packaged CMS | Custom build |
|---|---|---|
| Initial build | EUR 25,000 | EUR 55,000 |
| Licences/plugins 3 years | EUR 4,500 | EUR 900 |
| Maintenance + hosting 3 years | EUR 21,600 | EUR 28,800 |
| 3-year total | EUR 51,100 | EUR 84,700 |
Over 3 years, the CMS stays cheaper for a standard need. The custom build never closes the gap if functions remain classic: it is only justified by strong specific requirements.
Mini case study
Mr Faye, CIO of an institutional group in Dakar with a European subsidiary, evaluates both options for a multilingual corporate site. Need: editorial governance, validation workflow, integration with the internal directory. He costs the CMS at EUR 51,000 over 3 years, the custom build at EUR 85,000. As the business integrations are demanding but not exotic, he opts for a headless CMS compromise, gets the governance he wants and saves EUR 34,000 over 3 years versus a full custom build.

FAQ
Is a CMS less secure than a custom build?
Not intrinsically, but its attack surface is wider due to third-party plugins. A weekly patch policy sharply reduces the risk.
When does a custom build become unavoidable?
When you have heavy business integrations, specific security requirements or a need for total control that plugins cannot cover.
Is vendor lock-in worse with a custom build?
Differently. A CMS locks you into an ecosystem; a custom build locks you into a provider's knowledge. Require documentation and code to limit both.
What do licences really cost in 2026?
Between EUR 500 and 2,500 per year depending on premium plugins, managed security and multilingual or workflow modules.
Is a headless CMS a good compromise?
Often yes: it combines a CMS's editorial governance with a custom front's performance and security, at an intermediate cost.
