Been with Onyx for quite a few years, I've looked at other software but Onyx is so easy to use and covers everything we need from the diary to stock control. Plus you always get quick response from the admin if you have a problem. Keep up the good work and here's to many more years

I looked at many garage specific software programes and came across this one by pure accident. It is the easiest, program I have ever used. We started on version 2 and are now on version 4. It has a great function that uses DVLA to identify vehicles which is great when ordering parts. I would highly recommend this program and the cost against other similar programs just doesn't compare, this program is such excellent value for money and yearly costs are very low for what you get for your money. We would not be able to run our business efficiently without this program.

I have been very impressed with the offering from Onyx. Although I was initially attracted to the software due to the low cost, I have found that it is just as good as the more expensive offerings. I am particularly impressed with the willingness of Onyx to customise the product to our requirements for little or no cost.
