Booking & Ticketing Systems

Appointment scheduling, event tickets, and resource allocation with real-time availability, built on WordPress and paired with the right calendar and payment layer for the job.

The back-and-forth of manual booking turned into a single confirmed slot, with capacity rules and automated confirmations sitting behind the scenes.

Why bookings go wrong

The failure mode is almost always the same: two customers holding the same slot, because availability was cached, or the booking form and the calendar were not sharing a single source of truth, or a race condition at checkout let the second booking through before the first was committed. It looks like a rare edge case. It happens every month in practice.

A bookings system that does not treat availability as a transactional resource will eventually oversell. The fix is not a bigger plugin, it is a booking layer that writes to the calendar inside the same transaction that captures payment, with capacity rules enforced at the database level rather than in a front-end widget that hopes for the best.

What gets built

Each layer below is scoped up front, not stitched together after the first double-booking.

Availability and calendar integration

Real-time availability pulled from the authoritative calendar, whether that is Google Calendar, Outlook, a resource-management back end, or a custom schema. Two-way sync where it is needed, and read-only sync where it is not. Timezone handling tested against customers and staff in different regions, because that is where ninety percent of “booked at the wrong time” incidents originate.

Capacity rules

Per-slot limits, buffer time between bookings, blackout periods, and resource constraints (a room, a staff member, a piece of equipment) modelled explicitly. The same booking layer serves one-to-one appointments, class or group bookings, and ticketed events, without needing three separate plugins fighting over the same post type.

Payment and confirmation

Payment capture integrated directly into the booking flow: deposits, full payment, or pay-on-arrival with card authorisation, depending on the business model. Confirmation emails and calendar invites sent from the same event that wrote the booking, so there is no window in which a customer has paid but not been confirmed.

Ticketing for events

For event ticketing, the work extends to unique QR codes per ticket, a scanning or check-in flow that survives patchy venue wifi, seat or zone allocation where relevant, and resale or transfer rules that match the organiser’s policy rather than a plugin default.

Keeping it running

Booking systems are one of the most failure-sensitive parts of a site. A half-hour of downtime on a ticketing platform during a release window costs real money. Ongoing coverage sits under the 24/7 retainer framework with priority support, because outages during a sale event are not the moment to file a ticket.

A short call is enough to map the availability model, capacity rules, and payment flow before any code is written.
