Your team is competent, professional, and pleasant to work with. My case was a bit harder because I am so disconnected from paper work, but you guided me through the process and quickly answered all questions.

Billah & Associates proves that there are still Great Accountants available

Billah & Associates was recommended to me to help get my small business back on track financially after having several bad experiences with previous accountants. They went through the past 3 years of tax returns with me and found all the mistakes made by other companies. He corrected them and then worked with CRA to make sure everything was perfect again. I can’t give enough positive feedback regarding his assistance with my account and how confident I feel now that I have found such great financial assistance.
