HAQ Booking

HAQ Booking turns your WordPress site into an appointment booking system. Everything runs inside this plugin — no theme dependency and no required companion plugins.

Features

• Create services with duration, price and status

• Manage staff, working hours, breaks and assigned services

• Customer records with booking history

• Appointment list and admin calendar

• Availability engine with open time slots

• Mobile-friendly booking form via shortcode [haq_booking] or Gutenberg block

• Email confirmation, cancellation and reschedule notices

• Customer cancel and reschedule via secure token links

• GDPR export / erase personal data support

Admin screens

All screens live under the HAQ Booking menu and require the manage_haq_booking capability (granted to administrators on activation).

• Dashboard – today’s totals (confirmed, pending, cancelled), the next upcoming appointments, a setup checklist with progress bar and quick links.

• Appointments – book on behalf of a customer (existing customers are matched by email), edit staff, time, status and notes, delete, and filter by status.

• Calendar – month view with previous / next / today navigation, colour-coded by status; click any appointment to edit it.

• Services – name, description, duration in minutes, price and active / inactive status.

• Staff – name, email, phone, active switch, services offered and weekly working hours with work and break rows. New staff start with Monday–Friday, 9:00–17:00.

• Customers – searchable list with booking counters (total, completed, cancelled, no-show), WhatsApp number, messaging opt-in and private notes.

• Settings – business details, booking rules, email sender, currency and date/time formats with live preview, and the booking page.

• WordPress dashboard widget – today’s appointment counts at a glance.

Booking form

• Four steps: service → staff → date and time → your details, followed by a confirmation screen with the booking code.

• Optional “Any available staff” choice that picks a free staff member automatically.

• Name and email are required; phone and notes are optional.

• Works with any theme, uses no jQuery, and loads its assets only on pages that contain the form.

• Falls back to?rest_route= automatically if pretty REST URLs are unavailable.

How available times are calculated

For the chosen service, date and staff member, the plugin:

• Takes the staff member’s working blocks for that weekday.

• Removes the staff member’s break rows.

• Steps through the day using the Slot interval setting and keeps start times where the whole service duration fits.

• Removes times that overlap existing appointments (cancelled appointments free the slot).

• Removes times sooner than the Minimum notice and dates beyond the Booking window.

Appointment statuses

pending, `confirmed`, `completed`, `cancelled` and `no_show`. Choose **Pending** as the default status in Settings if you want to approve each booking manually.

Email notifications

Plain-text emails are sent with wp_mail() from the sender name and address set in Settings.

• New booking – to the customer (with a manage link), the admin notification email and the assigned staff member.

• Cancellation – to the customer and the admin.

• Reschedule – to the customer and the admin.

Customer self-service

Each booking gets a unique booking code and a secret manage token. haqb_manage=TOKEN, where the customer can cancel or pick a new time. Select your booking page in Settings so these links point to the right page.

Settings reference

• Business name and Admin notification email

• Slot interval (default 15 minutes), Minimum notice (default 1 hour), Booking window (default 60 days)

Optional extensions

An optional commercial add-on can extend HAQ Booking with messaging, payments and calendar sync. The free plugin works fully on its own.

Privacy

The plugin stores customer name, email, phone, optional messaging number, appointment details and related notes in your WordPress database. The free plugin does not send data to third-party APIs.

Data is kept in these custom tables: haqb_services, haqb_staff, haqb_staff_services, haqb_staff_availability, haqb_holidays, haqb_customers and haqb_appointments. Settings are stored in the haqb_settings option.

The plugin registers with the WordPress Export Personal Data and Erase Personal Data tools. Erasing anonymises the customer record and clears appointment notes while keeping the appointment history for your records. Suggested text is added to the privacy policy guide.

Deactivating the plugin keeps all data. Deleting the plugin from the Plugins screen removes its tables, settings and capability.
