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

  • 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

  • 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

  • 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.

    David Goadby

  • 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

  • I needed a reservation calendar for a holiday cottage, which the people who own it could use without any knowledge of HTML and other coding what so ever. I found PHPjabbers.com, and a booking calendar script that suited me. Since I am not that of a sophisticated website builder, the people at Stivasoft supported me all the way, I could ask them anything on any moment of the day. I am extremely grateful for the way they guided me through the process, and I will do business with them again for sure! They rock!!!!

    Catherine Lucas

  • 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

  • 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

  • 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 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

  • I came across PHPJabbers when looking for an online booking calendar to help reduce my booking inquiry administration. Straight away they seemed to be perfect for what I needed as the already extensive Pro package could be further tailored to suit my specific needs and branded to appear as an integral part of my site. From placing the order my booking calendar script was ready in just 5 days and the support received during the inevitable minor teething problems was excellent. I'm pleased to report that with the availability booking calendar having been on the site for just 8 hrs it has already paid for itself with the arrival of my first fully automated booking. Great stuff - no more inquiry emails to reply to, just confirmed bookings.
    Based on my experience I wouldn't hesitate to recommend PHPJabbers and Stivasoft to anybody and in fact already have done so.

    Sam Roberts

  • 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

  • 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

  • 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

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

    Stephen Downs

  • 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.

  • Reservation manager

    The integrated reservation management module provides facilities for administrators to manage client details and reservations. Quick controls, filters, and an export feature are available.

  • Collect offline and online payments

    The built-in payment integration module lets you accept online payments via PayPal and Authorize.net.
