Let our clients share their experience with the PHP Availability Booking Calendar script and how it has improved their online business.

  • The whole process of buying, installing and using the Availability Booking Calendar is effortless. Getting the reservation calendar script customized for my requirements was both easy and cost effective. Any issues I have had (mainly due to my error) have been very quickly supported and fixed even at weekends! I highly recommend PHPJabbers service and support. Don't hesitate just buy :o)

    Mark Watts

  • I was looking for a PHP booking script and came across phpjabbers.com, but I wanted quite a few mods done. These guy sorted them out quickly and efficiently. The after sales support is fantastic as well. Thanks Alexander 'Sasho' Valkanov and Veselin Stoilov.

    Mark Thompson

  • This booking calendar script and these people are fantastic! I am a complete novice trying to build a website, the help I received from Veselin Stoilov guiding me through setting up my booking calendar online, was absolutely brilliant. I can unreservedly recommend StivaSoft company and your site PHPJabbers.com.

    John Gibson

  • I would like to thank all the Stivasoft team for their dedication.
    I bought Availability Booking Calendar script, I had no idea how to get it up and running so I requested help. This team really work together to get you up and running. I would recommend them to anyone who is building a web site and who needs software to enhance the site.
    Thanks again.

    William Kent

  • Great product from a great Team!
    The booking calendar script is easy to install and even easier to use. The code is well structured and organized, it is rather easy to modify just with some basic coding knowledge or fully customizable for advanced programmers. Additionally, the team quickly and competently answers to any customer question.
    Five stars more than deserved!

    Luca Criscuolo

  • Just perfect, simple to install, simple to use. Just what I needed. So happy with this PHP reservation calendar.

    Stephen Downs

  • Availability Booking Calendar works great and is very easy to use. Setting up might even be easier. Some questions about implementing the script on a Joomla content page were answered almost immediately and a styling issue resolved. Great tool, great team, great support!

    Wout Natter

  • I purchased the PHP availability booking calendar script along with several specific modifications. PHP Jabbers provided the new code on time and to a high standard. Their prices are competitive, their support has been brilliant, and their coding is genius. Thank you PHP Jabbers!

    Jon Ireland

  • After looking at the availability booking calendar script and studied it I bought it. While Swedish is not the most used language it started out with problems to use the special characters. It took less than one hour for PHPJabbers support team to solve this for me. Now the booking form works perfectly - well invested money!

    Anders Sjoberg

  • Availability Booking Calendar from PHPJabbers and the guys who develop it are second to none! The booking calendar script is easy to install, and has lots of customizable features. These guys were very supportive, patient and above all very professional. I am a novice when it comes to installing and configuring software but nothing was too much trouble for them! I am very pleased with the results. Thank you again. I look forward to coming back for more great products and scripts!

    Jason Lihou

  • Your Availability Booking Calendar is a superb script. You have included an excellent admin panel that covers every function you need to implement a first class calendar booking system. It worked 'straight-out-of-the-box' with no problems. My client is delighted, and so am I, (this has saved me an awful lot of programming, testing and subsequent hair-loss!).
    I would also like to comment on the fantastic support I received (concerning a minor bug - which was diagnosed and rectified within 6 hours of reporting - very impressive).
    I will definitely incorporate some of your other scripts in future projects and have already recommended you to a number of colleagues.

    John Armstrong

  • We have been using the PHP Availability Booking Calendar script since October 2007 and have to say it is absolutely excellent. Simplicity of setup and use was a major factor in our final decision to use it on the Sol Villas Spain website.

    John Brown

  • I highly recommend the Availability Booking Calendar script. It is easy to install and administrate, yet it offers powerful features. This calendar booking system is also simple to use by customers. The PHPJabbers support is very quick and prices are very reasonable.

    Axel Schmidt

  • Stivasoft's Availability Booking Calendar is an excellent model for a variety of business booking needs. Even better, they quickly agreed to adopt their quality work for my unusual individual application requirements for a very reasonable price. Throughout the adaptation discussion, their support questions and answers were available within minutes. The final product met - and exceeded - my requests. I am very happy with Stivasoft and highly recommend their products and services. They are second to none.

    Robin Cunningham

  • My client has been using PHPJabbers' Availability Booking Calendar for some months now. I am pleased to say that both my client and I are very pleased with the product. The support required (mainly for self-modification) was concise and fast and this helped me to satisfy my client in a very short time.
    I am happy to highly recommend your reservation calendar script.
