Website & Payment Integrations

WordPress, Square & STORES integration
booking that fits your stack.

Drop a booking widget into your existing WordPress site, or connect Square and STORES so bookings collect payment automatically — no need to rebuild what you already have.

Free to get started No site rebuild required Works with Square & STORES payments

Built to fit your existing website & tools

Booking that plugs into what you already run

Keep your website and your payment provider — just add booking on top.

WordPress embed

Add a booking button or a full inline widget to any WordPress page with a short embed code — no plugin conflicts, no theme rebuild.

Square payment integration

Accept card payment at the time of booking through Square, so deposits and full payments are collected automatically.

STORES integration

Connect your STORES shop so booking and payment work together for businesses already selling through STORES.

Works anywhere, not just WordPress

The same embed code works on any website builder — Wix, Shopify, a custom site — not only WordPress.

Why businesses embed instead of switching sites

  • Keep your existing WordPress site, theme, and SEO history — booking is added on top, not a replacement.
  • Three embed options: a direct link, a popup "Book Now" button, or a fully inline widget — pick what fits your page.
  • Square and STORES integration means payment and booking happen in a single step for the client.
  • No developer required for the WordPress embed — copy one snippet into a page or widget area.

Frequently asked questions

Do I need a developer to add this to my WordPress site?

No — it's a short embed code you paste into any page, post, or widget area, the same way you'd add a YouTube video.

Can clients pay when they book, not just reserve a spot?

Yes, through the Square or STORES payment integration, payment can be collected automatically at the time of booking.

Does this work on website builders other than WordPress?

Yes — the embed code is plain HTML/JavaScript and works on most website builders, not only WordPress.
