Event Tickets Plus adds features and functionality onto the core Event Tickets plugin, so you can sell tickets with WooCommerce or Easy Digital Downloads. You can sell tickets on any existing post type or use The Events Calendar for a full events and ticketing solution. Event Tickets Plus gives you the power to keep ticket sales contained entirely within your site. This means no more sending buyers to a third-party portal or requiring an outside solution. Tickets have unique QR codes that make checking in your guests a breeze. Plus, the plugin allows you to take advantage of many of the powerful features already built into your commerce provider (reports, SKU tracking, etc) and apply those specifically to tickets. Whether soliciting free RSVPs to a community gathering or hosting a huge party with multiple price tiers, Event Tickets has got you covered.Sell tickets directly within your event listingsNo ticket fees (as required by most third-party ticket services) for site admins or buyersCreate all tickets from directly within the WordPress admin…no need to visit a third-party websiteAdd multiple tickets (free and/or paid) to any event, page, or postDrive sales with colorful Buy Now buttons in multiple viewsTicket stock countdown lets customers know how many tickets are left, with a clear Sold Out message once they’re goneStyle the ticket box using custom templatesInternationalized and ready for translationSet windows of time for when you want given ticket types to be on saleCustom attendee registration allows you to collect information from your attendees
