MEC Ticket and Invoice: worth it for MEC-based event ticketing

MEC Ticket and Invoice is a useful extension, but only inside the Modern Events Calendar ecosystem. It adds the practical pieces that turn MEC bookings into usable event tickets: emailed tickets and invoices, QR codes, attendee records, staff check-in, invoice management, and exports. Webnus also documents Apple Wallet passes, role-based check-in access, individual tickets for attendees in a group booking, and importing bookings created before the add-on was installed.

The strongest part is the check-in workflow. Staff can scan a QR code with a smartphone or the MEC utility app, see whether a ticket is valid or already checked in, and update the attendee status in the dashboard. You can also restrict check-in to selected WordPress roles, limit scanning to event days, and allow scanning a set number of minutes before the start time. Those controls make it considerably more useful than a simple PDF-ticket generator for workshops, classes, conferences, and local events.

Invoice customization is another genuine strength. The add-on supports company details, VAT information, logos, invoice numbering patterns, buyer fields, attendee fields, ticket types, and custom CSS. It can also create invoices manually for offline sales or guests, and older MEC bookings can be imported into the invoice system. For a business that wants to keep ticket sales, customer data, and entry control inside WordPress, that is a coherent workflow rather than a collection of disconnected tools.

The catch is the dependency chain. Ticket and Invoice requires MEC Pro; it does not turn the free calendar into a complete ticketing system. PDF generation also requires an API key from a service such as html2pdf or SelectPdf, so “downloadable PDF tickets” are not entirely self-contained. That adds another account, another possible failure point, and another integration to troubleshoot.

Cost is hard to ignore. Webnus lists the add-on at $119 for one site, $299 for five sites, and $499 for ten sites, with one year of updates and premium support. Because MEC Pro is required, the real cost is higher than the add-on price suggests. The Events Calendar with its ticketing extensions is a more established alternative for organizations prioritizing ecosystem depth, while EventPrime is worth considering when lower-cost bundled booking and ticketing matter more than MEC’s visual flexibility.

There is also evidence of ongoing edge-case maintenance. Recent changelog entries document fixes for invoices not being emailed after WooCommerce payment, multi-attendee PDFs showing only one attendee, expired tickets still allowing check-in, incorrect tax calculations, duplicate invoice numbers, and broken email layouts. Those fixes are positive, but they also show that payment, PDF, and attendee workflows deserve staging tests before a busy event goes live.

Verdict: buy it when MEC Pro is already your event system and you specifically need QR check-in plus branded invoices. If you are choosing an event platform from scratch, compare the complete cost and workflow against The Events Calendar, EventPrime, or a dedicated ticketing service before committing.
