Short answer
For a small service business in Spain in 2026, a custom website typically costs between €490 and €1,690. A one-page launch site is around €490; a 5-page business site with SEO and lead capture around €990; a site plus one practical automation around €1,690. DIY builders are cheaper up front but cost more over three years once you add plugins, fixes and lost leads.
What changes the price
Number of pages, online booking or e-commerce, how much copy and photography is ready, languages (Spanish + English is common), and how fast you need it live. A fixed scope agreed up front keeps the price predictable.
Cheap vs custom over 3 years
A €25/month builder looks cheaper than a €990 custom site until you add paid themes, plugins, a developer to fix them, and the leads a slow generic site loses every month. Over three years the gap usually closes or reverses.
What to avoid
Agencies that won't give a number before a call, 'unlimited revisions' with no fixed scope, and anyone who can't show you work. Ask for a fixed price, a clear scope and a launch date in writing.
Is a cheap template website a bad idea?
Not always, for a brand-new business testing an idea it can be fine. Once the site must win trust and capture leads, a fast custom site usually pays for itself.
Why do prices vary so much?
Scope. Pages, booking/e-commerce, languages and ready content move price far more than the agency's logo.
