About us


We designed Calendar Manager around an inventory business

We designed the Calendar Manager System to help us with our existing Inventory businesses. We were looking for a way to organise our bookings, including catering for the numerous amendments to bookings and also have an easy way to invoice our Clients and process their payments. So, Calendar Manager was born. We now couldn't work without the Calendar system and wonder how we managed without it! We hope you love it as much as we do!


Who's using Calendar Manager?

  • ‘Since starting QWERTY Inventories, I have found this booking calendar software invaluable! My clients, clerks and I find it very easy to use and the system allows us all to save time on phone calls and emails. There are so many features available which have been clearly designed by someone who knows the industry and the level of hard work involved. I would highly recommend this system as an affordable and efficient way of helping to manage a large workload and making the day to day running of the business much easier.’

    Qwerty Inventories

  • We love that Calendar Manager is a dedicated management system for our inventory business, the system is fast and reliable with many benefits to our clients and clerks, the integrated invoicing and payment system saves us so much time and effort. Our clients positively love the system and makes their busy offices more efficient and its available to them 24/7'

    Pinpoint Inventories

  • From the start the Calendar Manager team guided us though the system with its vast amount of features, its taken our inventory business from strength to strength, gaining a large customer base purely based on what the system can offer my clients and its ease of use


  • Starting as a new inventory company many years ago the Calendar Manager system was an invaluable selling tool and helped us put our company on the map ahead of our competition, now having used the Calendar Manager system for many years both ourselves and clients couldn't work wthout it, our Clerks use it daily to check the status of their bookings and our Clients never need to worry about missing paper copies as every uploaded document is stored in The Cloud
