“I contacted Williamson Accounting because they were recommended for their expertise in bookkeeping and accounting services. They resolved issues that I had with past GST/HST filing and as a result we obtained a sizeable refund! The things I appreciated were their knowledge and experience; professionalism and their ability to keep us posted throughout the process. I would highly recommend Williamson Accounting to anyone in the market ranging from small business bookkeeping to complex tax audit issues with the Canada Revenue Agency.”
