FAQ
Questions about website creation
A showcase site presents your business as a whole: who you are, your services, your references, your contacts. It has multiple pages and serves as a lasting digital anchor. A landing page has a single objective: to trigger a specific action (contact, sign-up, purchase). It is usually shorter, with no navigation menu, and entirely conversion-focused. Both are complementary — a showcase site builds trust, a landing page captures the lead at the right moment.
A custom showcase site starts from €2,000 excl. VAT. A conversion landing page between €800 and €1,500 excl. VAT depending on complexity. An e-commerce site or custom web application depends on the functional scope — budget between €4,000 and €15,000 excl. VAT for a complete project. We refuse generic templates: every project is developed custom, which explains our pricing. Send us your brief and we will reply with a detailed estimate within 48 hours.
For a showcase site, allow 3 to 5 weeks between validated brief and launch (design + development + testing). A landing page can be delivered in 1 to 2 weeks. For an e-commerce site or web application, timelines are 6 to 12 weeks depending on complexity. We work with a shared schedule and clear milestones — no dragging projects, no surprises.
