Time Slot – Booking and Appointment System

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 82% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.

   This plug-in simplified booking appointments and I couldn’t imagine a better one out there. It was easy to set up and for a great price too. Setting up payments was easy and there was documentation that explained anything I wanted to know more about!

   Among half a dozen of booking plugins, times-lot has been evaluated as the best choice for our small online+face-to-face company activity, and we enjoy using it: + Doing well the job with all essential features, as advertised, easy to configure. + An excellent clear and sound documentation for non expert installation. + A rather cheap and clear price (no complex price “scarfolding”). + The plugin internal php code is really well written up to our best expertise. +++ The development team is really kind and super reactive and effectively helping.Merci beaucoup 🙂 This topic was modified 11 months, 3 weeks ago by vthierry.
