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.

Before working with Williamson Accounting, I was having a hard time finding an accounting professional that I could trust and get along with, but at Williamson Accounting, they are great.

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.
