Our Story

“It can’t be this difficult!” When Stephanie was handed the Office Management of her husband’s business, she did not know she was going to need an accounting degree. Very quickly, she realized she did not have accurate financials & their rapidly growing business needed better reporting. She elicited the help of a QB ProAdvisor & soon began to see the results of good data reporting through QBDesktop. She was able to take a 10 hour per day job down to 3-4 hours per day through QBD & QBOnline automation. With the extra time available, she was able to take on other clients’ bookkeeping jobs, became certified in all QB products & went back to school for accounting.

In 2015, her husband decided to sell his business, & Stephanie decided to turn her hobby helping small business owners get their books correct into a full time endeavor. She wanted to make sure other small business owners were not struggling as she had & wanted them to know they could be set up for success from the start.

Now with 5 employees & a rapidly growing business, she has taught her staff to train the business owners so their clients’ data, from the first point of entry, is correct all the way through their books. More recently, she has grown the business by reaching out to mid-market clients & helping with conversions from QB Enterprise to QBOAdvanced with integrated apps and with Google Based to Microsoft based platforms. They are excited to see where the next few years will take them!


Account Mobility’s team dream is to be a million dollar company in 20 years & retire happy & healthy. If we can do it, we can certainly show our clients how to reach their financial goals, too! Actually, let’s try to make 1M in 10 years, why not shoot for the moon?


As an upsurging, nationwide bookkeeping, tax and strategizing practice our zooming success stems from encouraging our staff to meet their life dreams while having fun supporting our client’s financial knowledge, acting as a sounding board for growth & as their tax interpreter.


Our purpose is to inspire all business owners to love their business accounting team, since loving their business accounting is a hard sell!

Stephanie Mack

Consultant & Strategic Business Advisor

I love what I do! From the time I was a kid, I played banking for hours. I used to love the systems & processes of my banking setup. I would approve certain bills, stamp others & made sure everything in my kiddie bank setup was systematized & flawless. Much to the chagrin of my playmates, I loved my banking days. Now I have taken that love of process & systems to an adult level, helping clients with their accounting processes. And I still love it! Luckily I have found my calling & hope to ease the pain my clients are experiencing, so they too can enjoy their business.

Stephanie went back to school in 2014 to get her accounting degree from CCV. She is certified in every QB product & maintains an advanced certification in QBO. She is actively participating in the Woodard Institute’s Certified Transformative Advisor (CTA) program & was recently nominated one of Insightful Accountants’ Top 100.
