"I have been using SKS Avalon from the first day I opened my business back in 2004, in fact they were the ones that guided us through the whole process to get us up and running! We have always been super impressed with the accessibility we have with any issue relating to my accounts/company registration and general enquiry relating to the running of our business, always getting a quick and efficient response, if they are unable to help they have always pointed us in the right direction for assistance.

We have recommended their services to friends of ours who are equally as happy, our children who are now going self employed are being guided through the process with Paul. A great service."
