A booking wizard, a live price calculator and a before/after slider — and no plugins

A service business needs booking, quoting, a media comparison slider and lead capture.

The normal answer is four or five plugins, a page builder and a premium theme. Each one is a licence, an update cycle and a conflict waiting to happen. The stack grows every year and somebody has to keep it alive.

This build is the counter-argument, and it is made by opening the Plugins page on camera rather than by asserting it.

The booking wizard is the part that would normally take a plugin. Seven steps — what you need, how big the space is, how often, and when — with the price building on screen as you answer. It reaches an itemised $335 before anyone has to call you.

Alongside it: ten services under one standard, and a pricing page that gives you the number before rather than after. Flat rates quoted up front, the same team every visit, a twenty-four hour redo guarantee. A drag-handle before/after comparison, reviews, an FAQ and a contact form. A real person answers the phone, and the hours are printed next to it.

All of it survives the phone — the slider, the wizard, and the price that builds as you answer.

The before/after photograph is a placeholder, and the caption on the page says so. Not a footnote in a handover document — printed in the caption, where a visitor would see it, until real job photos arrive.

That is a small thing that matters. A before/after slider on a cleaning company site is exactly where stock imagery gets quietly passed off as the company’s own work.

• Scale: 27 published pages
• Verification: the slider, the wizard and the live price all confirmed working on mobile

Do I need booking, form and slider plugins to get these features?

Not here. The booking wizard, price calculator, before/after slider and contact form were all built as native WordPress widgets. The site runs on two plugins in total.

Does WPOS need a premium theme or a page builder?

No. This site runs on WordPress’s stock default theme with no page builder installed.

Does an interactive build like this work on a phone?

Yes — the slider, the seven-step wizard and the live price all work on mobile, and were checked there.
