About Us

Since 1983 SUM-IT Computer Systems has been providing practical and straightforward agricultural software to farmers throughout the UK and overseas.

We are proud of our reputation as a leading producer of high quality and affordable software for farms and other rural businesses.

Our complete range of highly functional and integrated programs are continuously developed by keeping abreast of what is happening in the industry, monitoring legislative changes and most of all by listening to what farmers tell us they really need.

We have always strived to develop software that is simple to use and cost effective, requiring the minimum of input to generate the necessary information in a flexible format. Without gimmicks or frilly add-ons, SUM-IT provide reliable management tools, which can be used at any level, catering for beginners, intermediate and advanced users wishing to extract the most from the system.

All the programs are supplied with comprehensive help files in plain English and simple data back-up routines are built into the software in order to provide maximum data security.

Users have access to our renown Software Support Hotline 12 hours a day, Monday to Friday, and 6 hours on Saturdays. Our friendly and knowledgeable staff are happy to answer any questions and guide Users through getting the most out of their SUM-IT programs. 

Based close to the M40 in Thame, Oxfordshire, SUM-IT is easily accessible to our clients for product demonstrations and in-house training.
