What do Augustedge Client's Say?

This year was my first with Augustedge and I am happy to say it won’t be my last. I enjoyed waking into a beautiful and clean office space. Lyndsey at front desk has always been cheerful with a nice smile and positive attitude ready to assist me. Tricia was fabulous not only did she finish our taxes quickly she gave me some great advise on how to structure my llc to benefit me for next year. Tricia is very easy to talk to and she was also able to refer another great professional to assist us with some future plans we have. I love supporting a wonderful entrepreneur! Thank you Tricia and staff.

I have a young business of four years. Tricia has been doing our accounting for the past three years and it has been great.

She is very progressive in thinking and processing all forms and reports needed. She is great to work with!

Roger Gardner - Safebathtub

A small business like ours has to be agile while keeping a lot of balls in the air. Tricia is fast to respond to questions, gets the work we ask her to do done in a timely manner, and has suggested ideas to make our business more profitable. In other words, instead of being a cost, she is an asset for our business.
