In ten seconds.

Pick your trade. We'll show you a real, working website built for businesses like yours, no signup, no email, no callback. Just click and look.

Every trade gets its own bespoke design, plumbers shouldn't look like hairdressers, and tilers shouldn't look like locksmiths. 25 trade-specific designs and counting.

We'll build a free demo with your business name on it. No card, no callback.

Don't see your trade? Tell us and we'll build it.

What's different

Your own customer portal.
No other agency gives you this.

Pay once and you get a private dashboard at mantixx.co.uk/portal, the same way you'd manage your bank or your Netflix.

  • Request changes in-app
    Update copy, swap photos, change opening times, upload new images, done inside 24 hours. No more chasing your web guy on WhatsApp.
  • One-tap add-ons
    Online bookings, Google reviews widget, WhatsApp button, lead-alert SMS, tick the boxes, pay through Stripe, we build it.
  • Live preview of your site
    See exactly what your customers see, right from the dashboard. Spot a typo? Two taps and it's fixed.
  • Billing on your terms
    Update your card, download invoices, cancel any time, all self-service through Stripe. No awkward emails.
