"We have recently signed up to We have found the Diary to be extremely user friendly, we can now do so much more than our previous system, and the best part is, with a lot less time spent in front of a computer! All human error has now been taken away from the booking management process, which leaves us more time to focus on our customers. Thanks for making our lives so much easier."


Owner, Ballyliffin Townhouse, Ballyliffin, Ireland

"The Diary is an exceptionally good tool, it has excellent guest history and invoicing features which we really appreciate. We would gladly recommend GuestDiary to any small to medium sized Hotel or Guesthouse owner."


Owner, Caisleain Oir Hotel, Annagry, Ireland

"I am using at my B&B for the past 4 months and I love it. It made bookings transfer, invoicing, shift reconciliation, booking tracking and other operation so much easier. I save so much time that I can use doing other jobs in the business. My staff got more time to do other necessary duties and they love it as I do. It's very easy to operate, navigate through it. Diary has a live chat feature where the guys are always there to help if you experience any difficulty. The Diary is constantly improving through the feedbacks from users and getting updates. I highly recommend to anyone running hospitality business."

Best Loved Features

We often find it's the little things that count, when a feature is requested, if it make sense we will add it .. no extra charges. The features our customers are most happy to have include:



We have spent a long time making everything as easy as possible to use, regardless of your ability to use a computer. Most features are at hand with a click of a button rather than being hidden away in another page.



Customise the colours of pills, and how they are displayed, so at a glance the diary makes sense to you.

Customising the colours was one of the first requirements requested when hotels were moving to us from another system, using a familiar colour scheme means moving to is less disruptive to your daily operations. Some hotels like pills to fill the diary grid, others like smaller pills, the can do both!



You don't need to have servers or special hardware in your property to use, as long as you have internet access you can use the diary from any location. Our 'Cloud PMS' is simply running on the internet, if your computers crash, your don't lose your data, if you want to check something from home that's no problem.



When a booking is made on, your website or any other connected booking engine, the booking is automatically entered and assigned to a suitable room. This also means you don't have to manually update your availability .. our diary does that for you.
