Hear What Our Clients Have To Say

“An accurate person. Payroll matters were clear and organized. Written company communication was detailed and precise. Financial issues were delivered on a timely basis.”


Estate Electric, Burlington, Ontario

“We have been using PatNCat Co. (Cathy) for 5 years now. Very pleased. We have gave them many challenges over the years, and they have delivered to us well. They have gotten us out of many issues and resolved things quickly. Also any small things we did not understand with running a small business they were able to provide us with answers. Very happy with our bookkeeping services.”

Tara M.

Low Price Auto Glass, Ottawa Ontario

“Having had unsatisfactory experiences with the last two bookkeeping companies I was apprehensive about having to look for a new bookkeeper.

Fortunately, we found PatNCat Co. and they have been managing all our bookkeeping since June 2014. PatNCat Co. (Cathy) is amazing. She has won my confidence and has taken away all my concern related to my bookkeeping needs and is working seamlessly with my accountant. She responds quickly to our requests, invoices, and other accounting needs. She is very detail oriented and takes the time to explain if you have any questions. I highly recommend PatnCat Co. and can not even begin to calculate the hours and money she has saved us in the past year.

I especially like the personalized attention that I receive from PatNCat Co. which I have not found with other accounting or bookkeeping agencies. PatNCat Co. (Cathy) actually seems to enjoy bringing order to my chaos!”

If you want the straight goods and prepared for the honesty that is hard to find these days? Then you have found the best!”
