What our customers say about GS...
We tried other systems and, while each one was good at one or two tasks, none of them did everything we wanted.
If I can use this program anyone can as it’s very technician-friendly. While other programs can be confusing, GS Onestop is easy to use – from the initial job quotation and service booking through to creating the final invoice.
We have been using GS Onestop as our workshop computer program for over 3 years now. We couldn’t be without it, the program works extremely well and caters for all our workshop needs, from stock taking to invoicing – it covers it all.
The customer service is great, Cassie, in particular is super helpful and always goes out of her way to ensure we get any issue resolved quickly and efficiently. The training was great in the outset – super patient with us, and explained things clearly.
Really great workshop programme, would highly recommend.
We've been using GS Onestop for a couple of years: It's very user friendly and there's no financially driven tie-in. It's has been our best investment over the last 5 years.
“I’ve been using GS Onestop since its launch and have been impressed by its functionality and ease of use.
“The Autodata Service & Repair function has been invaluable in helping me plan my day efficiently as well as calculating service times and costs. And in-built online ordering through AlliCat ensures I always have the parts I need, when I need them. In addition, Autodata Online is available instantly, giving technical guidance for the car being worked on, speeding up the repair process.
I recently had my Motor Codes Garage Audit, the inspector from the RAC was very impressed with the SMS communication function within GS Onestop.
I received a 100% award from the inspector”
We have been using GS Onestop for over 12 months now and we are very satisfied with it. We found that it produced more professional looking invoices for us and we found the Accounts side of the system very useful. We have found GS Onestop has improved our image to our customers and made producing our year end accounts a lot less hassle
