Every screenshot on this site comes from one of these five businesses. They are published on Vashana the same way your site would be, so instead of looking at pictures you can open them, book something, fill a cart and see how they behave on a phone.
None of these are customers. We built and published all five ourselves to show what the product makes — the names, addresses and phone numbers are invented, and any booking you make is a real booking against a business that does not exist.

A trailer rental yard. Whole-day hire, paid up front, with a rental agreement to accept and a pickup PIN at the end.
Pick two dates on a trailer and take it all the way to payment.
Note: Checkout runs in Stripe’s test mode, so no card is ever charged.

A barbershop with three chairs, each with its own services and opening hours. Booked online, paid in the chair.
Choose a barber, a service and a time — the booking completes for real.

Guided kayak trips sold by the seat, with departures that fill up and one tour you can buy out entirely.
Watch the seat count fall as you add people to a departure.

An outdoor goods shop with a product grid and a working cart.
Add a couple of things to the cart and open the checkout.

An electrician’s site: what they do, what it costs, and an enquiry form. No booking, no cart — some businesses need neither.
See what the plain version looks like when nothing is being sold online.
Describe your business once. You get a site like these — copy, photography, booking and payment already wired together — and you edit whatever you disagree with.
