Three tiers, three finished sites. Not pictures: you can click through them, try the form and the booking flow. The company in them is not real, and they double as the templates the delivery starts from.
The sample sites are in Slovak: they were built for a Slovak car service. Your site gets your language, your copy and your colour.
One page: services, opening hours, phone. People find you and call.
Six pages and online booking. The customer books a slot without calling.
Nine pages and a customer portal. The site works at night and brings people back.
The difference between the tiers should be visible at a glance: 4 / 7 / 11 sections, from a plain one-pager to a site with booking and a customer portal.
