The verdict in three sentences
A serious B2B corporate rebuild in Miami costs in 2026 between 18,000 and 45,000 EUR for custom Next.js, or 6,000 to 12,000 EUR on a premium WordPress theme if you accept customization limits. The true cost of ownership lives in the maintenance retainer (400 to 1,200 EUR/month) and hosting, not just the initial build. Plan a timeline of 8 to 14 weeks and an agency day rate of 550 to 750 EUR to frame your budget from the specification stage.
What a B2B rebuild costs in Miami in 2026
The budget depends first on technology and the level of customization. A 15 to 30 page corporate site with CMS, qualified forms and CRM integration is not priced like a dressed-up theme.
| Line item | Premium WordPress theme | Custom Next.js |
|---|---|---|
| UX/UI design | 1,500 - 3,500 EUR | 4,000 - 9,000 EUR |
| Front-end + CMS build | 3,000 - 6,000 EUR | 10,000 - 26,000 EUR |
| CRM/marketing integration | 800 - 1,500 EUR | 2,000 - 5,000 EUR |
| Initial technical SEO | 700 - 1,200 EUR | 1,500 - 3,000 EUR |
| QA + training | 500 - 1,000 EUR | 1,500 - 2,500 EUR |
| Total build | 6,000 - 12,000 EUR | 18,000 - 45,000 EUR |
Custom is justified when the site is a commercial asset: controlled load times, reusable components, editorial autonomy and a 4 to 5 year lifespan.
Cost of ownership: maintenance, hosting and recurring fees
The classic trap is budgeting only the build. Over three years, recurring fees often weigh as much as the rebuild itself.
| Recurring item | 2026 range | Frequency |
|---|---|---|
| Application maintenance | 400 - 1,200 EUR/month | Monthly |
| EU hosting (OVH/Scaleway) | 40 - 180 EUR/month | Monthly |
| Domain + certificates | 20 - 60 EUR/year | Annual |
| SEO support | 700 - 2,500 EUR/month | Optional |
| Ad hoc changes (day rate) | 550 - 750 EUR/day | On demand |
EU hosting with OVH or Scaleway makes GDPR compliance simple: data stored in Europe, framed subprocessing, easier records. It reassures your enterprise clients.
Agency, freelancer or studio: which to pick
| Criterion | Freelancer | Agency | Specialist studio |
|---|---|---|---|
| 2026 day rate | 350 - 550 EUR | 550 - 750 EUR | 700 - 1,000 EUR |
| Timeline 15-30 pages | 10 - 16 weeks | 8 - 14 weeks | 6 - 10 weeks |
| Service continuity | Low | Good | High |
| Design system delivered | Rare | Sometimes | Always |
| Fit for large accounts | No | Yes | Yes |
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sarah, communications director of a 180-person industrial mid-cap in Miami, weighs a 9,000 EUR theme against a 32,000 EUR custom Next.js rebuild. Custom adds 23,000 EUR to the build, but her site generates 40 qualified leads per month. By lifting conversion from 1.8% to 2.6% through fast product pages, she gains about 18 extra leads per month. At a 12% sales close rate and a 14,000 EUR average deal, that is nearly 30,000 EUR of additional monthly revenue: the build gap pays back in under two months.
FAQ
How long does a B2B corporate rebuild take?
Plan 8 to 14 weeks for a 15 to 30 page agency build: 2 to 3 weeks of scoping, 4 to 7 of production, 2 to 3 of QA and content. A simple theme can drop to 6 weeks.
WordPress or Next.js for a corporate site?
WordPress fits when editorial autonomy dominates and budget is tight (6,000 to 12,000 EUR). Next.js wins when performance, technical SEO and scalability are strategic, at 18,000 to 45,000 EUR.
Do I need a detailed specification?
Yes: it moves the quote by 30 to 40%. A precise spec (site map, templates, integrations, volume) avoids change orders and secures the 8 to 14 week timeline.
What maintenance budget should I plan?
Between 400 and 1,200 EUR/month depending on service level (fixes, updates, small changes), plus 40 to 180 EUR/month of EU hosting.
Does custom really improve SEO?
Yes, indirectly: an optimized Next.js foundation improves Core Web Vitals and speed, two ranking factors. Gains show over 4 to 6 months combined with a content strategy.
