What Does a Professional Business Website Cost in 2026?

Three agencies, three quotes: EUR 3.500, EUR 18.000, EUR 65.000. All three describe "a professional website for a business." That gap is not a sign of market opacity. It reflects fundamentally different scopes of work that sound identical on paper.

This guide follows the Diátaxis framework: first, the explanatory section on cost structures and price drivers, then concrete price ranges with traceable parameters, and finally a before-and-after example from mid-market practice that translates directly into your own planning. A guide without working examples is not a guide.

Why Quotes Vary So Widely

A website is not a standardized product. The price depends on the interplay of design, technology stack, content architecture, integration complexity, and what keeps running after launch. Three typical starting points illustrate the range:

Scenario A. A service provider needs an online presence. An off-the-shelf WordPress template is customized, the logo and brand colors applied, five pages filled in. Cost: EUR 1.500 to 4.000. Functional, but visually indistinguishable from the hundred competitors using the same template.

Scenario B. A manufacturing company with 80 employees needs a structured website with a product catalog, multilingual navigation, GDPR-compliant contact forms, and a CMS the marketing team can operate without developers. Cost: EUR 12.000 to 35.000.

Scenario C. A B2B systems supplier integrates its ERP, runs a configurable product finder, and publishes content in four languages. Cost: EUR 50.000 and up.

Comparing quotes from different scenarios is not a pricing decision. It is a confusion of scopes.

Five Factors That Drive the Price

1. Design: Template or Custom

Templates spread design effort across many projects, which is why they cost less. Custom designs start at EUR 3.000 to 8.000 for concept and mockups alone. The difference becomes relevant once visual differentiation matters competitively or a corporate identity needs to be implemented with precision.

2. CMS and Technology Stack

WordPress is the lowest-cost option for content management. Headless CMS platforms such as Contentful, Storyblok, or Sanity cost significantly more in setup and licensing, but offer genuine content independence and simplify multichannel publishing. Enterprise systems like TYPO3 or Sitecore can reach EUR 40.000 for CMS integration alone.

3. Technical SEO and Performance

Core Web Vitals are not an optional add-on: an LCP (Largest Contentful Paint) below 2.5 seconds and a Cumulative Layout Shift below 0.1 directly affect Google rankings. Each additional second of load time measurably reduces conversion rates.^[4] Retrofitting SEO onto a poorly structured website means paying for the development work a second time.

4. Accessibility and GDPR

The European Accessibility Act requires commercial websites to meet extended WCAG 2.2 conformance starting June 2025.^[6] Companies that ignore this during development are buying expensive rework. GDPR-compliant cookie management, form architecture, and data storage belong in the scope document from day one, not as an afterthought.

5. Integrations and APIs

CRM connections (HubSpot, Salesforce), ERP exports, calendar booking, live chat: every integration costs development time. A simple interface starts at EUR 1.500. Bidirectional synchronizations with error handling and logging run from EUR 8.000 to 15.000 per interface depending on complexity.

Price Ranges by Project Type

The following overview shows realistic ranges for projects in the DACH mid-market segment (net prices, excluding ongoing costs):

These ranges align with market observations published by the Federal Association for the Digital Economy on agency projects in the mid-market segment.^[2]

Hidden Costs: What Keeps Running After Handover

A common planning mistake: the budget covers concept, design, and development. What comes next is missing from the quote.

Hosting and infrastructure. Managed hosting for a professional website starts at EUR 50 per month. With SSL management, multiple domains, and active security monitoring, costs quickly reach EUR 150 to 300 per month.

Maintenance and security updates. CMS systems require regular updates. WordPress installations without an active maintenance contract frequently show unpatched vulnerabilities after 18 months. A professional base contract costs EUR 200 to 500 per month.

Content management. Teams managing content in-house need initial CMS training and a clearly structured backend. Outsourcing content means paying by the hour. Either way, it costs more than nothing.

Post-launch additions. On average, supplemental work in the first two years after go-live amounts to 20 to 30 percent of the original investment.

Rule of thumb. Budget at least 15 percent of the project price as a reserve for follow-on costs in the first year of operation. On a EUR 20.000 project, that is EUR 3.000 that experience shows will be needed.

Before and After: A Real Mid-Market Example

Starting point. A mid-market company in the capital goods industry, 70 employees, pure B2B sales. The website dates from 2017: outdated WordPress version, no mobile layout, 8-second load time. For the most important product categories, the company has dropped to pages 3 and 4 in Google. Existing customers still find the site. New leads rarely arrive through it.

Scope definition. In two structured workshops, the team and the agency define the scope in writing:

• 38 pages, including 14 product categories with filter navigation
• New design based on a revised corporate identity
• CMS backend for the in-house marketing team without developer dependency
• Technical SEO foundation: Core Web Vitals, Schema Markup, XML sitemap, structured URLs
• GDPR-compliant contact form with double opt-in logic
• German and English language versions

Outcome after implementation. Investment: EUR 24.000 net, project duration 16 weeks. Load time after launch: 1.9 seconds. Visibility for the three most important keyword clusters: from page 4 to page 1 within four months. The marketing team manages content entirely in-house; external editorial costs for standard copy are eliminated.

What this example shows. Scope clarity before the first quote prevents change orders. Anyone who does not fix the scope in writing is buying a black box. That applies equally to the client and the agency.

What a Credible Quote Must Include

Every professional agency quote contains at minimum these six elements:

• Scope of work with specific page counts and a feature list. Not: "Development of a business website."
• Technology stack with justification. Not: "We use WordPress because we know it."
• Milestone plan with defined acceptance points and a payment schedule. Typical model: 30 percent upfront, 40 percent after design sign-off, 30 percent after go-live.
• Ongoing cost breakdown covering hosting, maintenance contract, and CMS or plugin licensing.
• SEO baseline. At minimum: technical SEO, meta structure, and a load time target in concrete figures.
• Definition of Done. Written agreement on what "finished" means before the project starts.

If any of these elements is missing, that is not automatically a disqualifying signal, but it is a clear reason to ask before signing.

Conclusion

Business website costs cannot be reduced to a single number. The realistic price range for a professional business website in the DACH mid-market sits between EUR 8.000 and 35.000 for a clearly defined B2B scope. Complexity, integrations, and multilingual requirements push the ceiling higher.

What separates a well-executed project from one that turns expensive in hindsight: scope clarity before the first quote, a maintenance plan from day one, and a development partner who can justify their technology stack without defaulting to stock answers.

Anyone collecting three quotes should make sure all three describe the same scope.
