WP Booking System – Booking Calendar

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

Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

184 searches this plugin appeared in over the last 90 days, 20 listed. 131 left out as unrelated or noise (years, numbers, stray words).

   We have been using WP-Booking-System for more than 2 years now, and it’s very stable, suits our needs, and if not Roland and his team helps us get it customized to fit our needs. I can only recommend this plugin. /Jan

Happend already 2 times when you change make a change to the invoice number settings, all your currently created invoices are changed cant set an manual booking to paid when its paid online (to correct the missing booking die to the previous bug) not working correctly on a android tablet, sometimes can’t select a value I can go on and on and on…..time to start looking for a better solution as in can’t trust on this plugin. Costing me more time/money while it should safe me time

   Really happy with WP Booking System. It is my go-to for clients who need to add booking function to their website. I’ve used for a few projects so far and it ticks all the boxes. On top of that super responsives support which is invaluable. Had a feature request that was addressed and added to the plugin with days, very happy and highly recommend!

   A fantastic plugin, very easy to set up and with multiple options for creating a booking system at a great price.We had tried other plugins before and found them very cumbersome and complicated. Finding this solution has been a very pleasant surprise.We also want to highlight the technical support: they are very polite, respond quickly, and provide solutions. Wonderful!

   I use this plugin on a client’s website for a motorhome rental business and it works very well. The functionality covers everything we need for availability management. What really stands out is the support – they helped us solve a very specific iCal synchronization issue quickly and professionally. Highly recommended!

   An high end property needs a high end booking system – WPBS is the perfect fit We own and operate a globally unique, ultra-sustainable holiday rental property, Warksburn Old Church. We only offer two booking channels, direct (via WPBS) and Airbnb, where we are listed in the exceptionally rare ‘Luxe’ category. So we need our booking engine to do two things: 1) offer direct bookers a totally reliable and seamless experience; and2) sync perfectly with our Airbnb calendar.WPBS does both of those things perfectly: normally it just sits there and does its job, enabling customers to arrive, find a date, book and pay with the lowest possible level of ‘friction’ on their booking journey, and with zero intervention from us on a day to day basis. But the core Calendar, Discounts and Coupons modules do allow us to do some reasonably sophisticated things when we choose to do so: for example, setting ‘deep links’ from our marketing socials to land on particular days in the calendar with a pre-set discount applied only to those days. But the real value in any software is how good the tech support is when things are not normal. This is where we’ve have been most impressed with the service WPBS offers its customers. As an example, when Airbnb unilaterally changed their calendar sync methodology, Roland and the team at WBPS issued a patch within hours to keep everything linked up seamlessly. The tech support, from real human beings who are clearly both passionate and deeply knowledgeable about their product, is simply world class. Great service isn’t just about ‘when things go wrong’. We have also found WPBS to be highly responsive to requests we have made for optimisations. For example, ensuring post codes captured within the booking engine carry over into the payment modal (Stripe in our case). This ensures that this critical field for Card Holder ID Validation is pre-filled with correct data. In short: could not be happier with WordPress Booking System. 10/10 on all counts. Highly recommended
