Client’s Feedback

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.

We started off as a small company and needed assistance with bookkeeping and year-end tax preparation. I am happy to say that within three years, we have enjoyed substantial growth and are well on our way into being a success story. Throughout this growth period, Williamson Accounting has been with us side by side- each month, providing updated financial reports and guidance needed to direct our business and keeping us on track. At the company’s year-end, they have been dependable in providing tax planning we need including issuing and filing T4’s for our employees and corporate and personal tax returns. They are a great resource for any start-up or growing business and we highly recommend their service.

Williamson Accounting has been a solid partner in keeping us on track with our day to day operations as well as future business.

I am real estate Investor. A few years ago I needed an accountant to provide some personal tax planning and year end service for the properties held in my corporation. I reached out to Williamson Accounting and they provided the professional services I desired.
Over the years they have supported me through other startup business ventures and other personal changes that have took place. They are always a phone call away. I highly recommend their service.

In the startup phase of my business I needed some challenging questions answered relating to payroll and accounting systems. Rather than spending hours researching it, I let Williamson Accounting handle it – providing clear-cut answers to my issues instantly.

But no business is too small for Williamson Accounting and they gave me the one-on-one consultation I needed and great professional guidance. With their help I know I am making smart decisions in handling my business finances.

They took time out to understand my business and needs, listened to all my ideas and provide me with great service overall.

I started investing in real estate a few years ago when I started educating myself. One of the key ingredients of success in this business is to have a strong team. I was looking for an accountant on my team with industry knowledge that can help me to stay organized and profitable.
