Bookyzo – Booking & Appointments

Bookyzo turns your WordPress site into a real booking system, whatever you’re booking. Add a staff member for one-on-one appointments, a table for restaurant reservations, an event for ticketed occurrences, or a generic slot for anything else — set its availability, drop a booking form onto any page with a shortcode or block, and start taking bookings. No page builder plugin, no external booking service, no WooCommerce required.

Why Bookyzo?

• All four booking types — Appointment, Table, Event, Slot — in the free plugin, not locked behind an upsell

• Runs entirely on your own site — your booking data stays in your own database

• No WooCommerce dependency — works on any WordPress site

• A real Vue-powered admin panel, not a wall of settings screens

• No limits on bookable items, shifts or bookings — add as many staff members, tables, events and slots as you need

Four booking types, one plugin

• Appointment — one staff member, one customer per time slot (haircuts, consultations, tutoring)

• Table — a restaurant table or venue space with a party-size capacity

• Event — a specific date/time occurrence you create yourself (a class, a workshop, a ticketed show), sold by ticket quantity

• Slot — a generic recurring time slot with room for more than one booking at once (a rental, a group session, anything that doesn’t fit the other three)

g. lunch and dinner), or specific dates you add yourself for Event. Available time slots (or your entered event dates) are kept up to date automatically in the background.

For events, the booking form can optionally ask for each ticket holder’s name when someone books several tickets.

Booking calendar

A day/week/month calendar in the admin panel shows every booking, color-coded by status. Click a booking to see its details or change its status, or add a walk-in/phone booking yourself straight from the calendar.

Booking list & CSV export

Filter every booking by date, bookable item or status, change status inline, and export the filtered list to CSV whenever you need it outside WordPress.

Customer booking widget

Add [bookyzo_booking] anywhere with the shortcode, use the Booking Form block, or drop it in with the Elementor widget if you build pages that way. ics file — no account required.

Customer management

Every customer is saved automatically the first time they book — searchable by name, email or phone under Bookyzo → Customers, with notes and tags you can add yourself. Already have a customer list elsewhere? Import it from a CSV file.

Email notifications

Automatic emails when a booking is received, confirmed or cancelled, plus a reminder email the day before it’s due. Every email carries the booking’s own details — number, quantity, total and location — and a self-service link the customer can use themselves: from it they can move their booking to another open time or cancel it, right up to your cancellation cutoff.

Every email’s subject and body is a plain-text template you can edit yourself, with placeholders for the customer’s name, the bookable item, the booking time, the total and your business name.

Payments

Mark bookings as paid manually for cash or in-person payments, or connect a Stripe account to let customers pay online by card when they book. An optional flat tax rate is added to every paid booking’s total automatically.

Dashboard

See today’s, this week’s and this month’s booking counts at a glance when you log in.

Developer friendly

Actions and filters throughout (REST controllers, pricing, rate limiting, notifications) and a REST API under bookyzo/v1. See Other Notes for the hook list.

Customer accounts

Customers can optionally create an account (turn it on under Bookyzo → Settings ) and manage their own bookings from a [bookyzo_account] page — upcoming and past bookings, rescheduling and cancelling within your cutoff. Off by default: guests can book, and manage that booking from the link in their email, without one.

Growing out of the free plugin (Pro)

Everything in this plugin is complete on its own, with no limits and no locked-out UI. Bookyzo Pro is a separate paid add-on with more features: services with per-staff pricing and “any available staff” booking, deposits and PayPal, SMS/WhatsApp reminders on your own schedule, seasonal and dynamic pricing, add-ons and booking fees, custom form fields, a table floor plan, event ticket tiers with QR e-tickets and a check-in scanner, staff calendar sync, an analytics dashboard, and WooCommerce checkout.

External services

Bookyzo runs on your own site and stores bookings in your own database. It connects to these outside services only in the cases described.

Stripe (online card payments)

Used only if you turn on Stripe under Bookyzo → Payments and enter your own Stripe API keys.

• When a customer chooses to pay online, the booking widget loads Stripe.js from https://js.stripe.com/v3/ and the card details go straight from the customer’s browser to Stripe. They never pass through your site.

• Your site sends Stripe the amount, the currency, the booking’s ID and the customer’s email address (for Stripe’s receipt), to create the payment, and later asks Stripe whether that payment succeeded.

• When you refund a booking paid by card, your site sends Stripe the payment’s reference and the amount to refund.

• Stripe calls your site’s webhook address to report payments it has completed.

Google Calendar (add to calendar link)

The booking confirmation screen and emails include an “Add to Google Calendar” link. Nothing is sent to Google unless the customer clicks it; the link then opens Google Calendar with the bookable item’s name and the booking’s time filled in.
