Booknetic

Booknetic is a WordPress appointment booking plugin with over 120,000 active installations, sold through Envato where it holds a 4.9 rating. It targets service businesses that have outgrown a simple booking form, covering staff, locations, and services alongside a customer panel that lets clients reschedule and manage appointments themselves, all inside a drag-and-drop booking widget styled to match the site.

Automation is where it pushes hardest. A workflow builder fires confirmations, reminders, staff notifications, and follow-ups on configurable triggers, with Twilio SMS verification available to confirm customers before a slot is held. Payments run through Stripe, PayPal, 2Checkout, and Mercado Pago among others, Google Calendar two-way sync and Outlook are supported, and the plugin claims 50+ integrations including HubSpot, Zoom, Zapier, and Google Analytics. A separate Booknetic SaaS product turns the same engine into a multi-vendor booking platform you can resell.

There is no free version — a sandbox demo and a 14-day money-back guarantee stand in for one. Annual licences run Basic at $45, Standard at $99, Premium at $199, and Elite at $299, tiered by domains, payment gateways, and how many of the 50+ add-ons are included, while a one-time lifetime purchase covers everything in Elite with 12 months of renewable support. That lifetime option is the main draw against subscription schedulers. It fits WordPress agencies and service businesses that want deep booking automation on infrastructure they own.
