The verdict in three sentences
WordPress wins when the need is standard, the budget tight and time-to-market short; a custom build wins when performance, security, integration with your systems or specific business logic become structural. The trap is comparing entry prices: over 3 years, maintenance and security reshuffle the deck. In Berlin in 2026, an initial gap of EUR 9,000 can halve on total cost of ownership.
Upfront price: what you see
The entry quote hides different assumptions. WordPress leverages a plugin ecosystem; a custom build pays for bespoke development but avoids third-party plugin debt.
| Line item | WordPress | Custom build |
|---|---|---|
| Initial build | EUR 6,000-14,000 | EUR 15,000-35,000 |
| Delivery timeline | 5-9 weeks | 10-18 weeks |
| Plugin dependency | high | none to low |
| UX customisation | medium | total |
| Systems integration (CRM, ERP) | via plugins/API | native, bespoke |
| Editorial autonomy | very good | good (headless CMS) |
Total cost of ownership over 3 years
TCO adds the build, annual maintenance, security and the cost of incidents. It is the only figure that allows an honest CFO decision.
| Line item over 3 years | WordPress | Custom build |
|---|---|---|
| Initial build | EUR 10,000 | EUR 24,000 |
| Maintenance / updates | EUR 1,500-4,000/yr | EUR 2,000-5,000/yr |
| Security (plugins, patches) | EUR 800-2,000/yr | EUR 500-1,200/yr |
| Incident cost (probability-weighted) | EUR 1,500-4,000 | EUR 500-1,500 |
| 3-year total (estimate) | EUR 21,000-33,000 | EUR 34,000-48,000 |
WordPress stays cheaper over 3 years in most standard B2B cases. A custom build pays off when the site is a strategic asset (strong lead generation, deep integration, high traffic).
Mini case study
Claire, CFO of a 60-person industrial SME in Berlin, is deciding between an EUR 11,000 WordPress quote and an EUR 26,000 custom build. Her site generates 40 qualified leads a month. She reasons in 3-year TCO: WordPress lands at EUR 28,000, custom at EUR 41,000, a EUR 13,000 gap. But the custom build natively integrates her CRM and a product configurator expected to lift conversion by 15%. Estimated gain: 6 more leads a month, worth EUR 400 each, i.e. EUR 28,800/year of additional pipeline. The EUR 13,000 gap is absorbed in under 6 months. She picks the custom build.

Is WordPress less secure than a custom build?
Not inherently, but its attack surface is larger due to third-party plugins. In 2026, a well-maintained WordPress (auto-updates, WAF, backups) is safe; the risk comes from un-updated plugins. Budget EUR 800-2,000/year for serious security.
Does a custom build lock me to the agency?
Only if the code is neither documented nor transferred. Require source code ownership, technical documentation and access to a Git repository. Clean custom code is maintainable by any competent developer.
Can I migrate from WordPress to custom later?
Yes, and it is a common path in 2026: start on WordPress to validate the market, then move to custom when the site becomes critical. Budget EUR 8,000-20,000 for the rebuild, with content reusable.
What actually costs a lot over 3 years?
Not the build but unplanned maintenance: premium plugins to renew, security patches, feature updates. An annual budget of EUR 1,500-5,000 is realistic; ignoring it skews any comparison.
Which is best for a short time-to-market?
WordPress, hands down: 5-9 weeks versus 10-18 for custom. If you must launch before a trade show or campaign, WordPress then iterate is often the most rational 2026 strategy.
