"I am so happy that we finally found the perfect partner to help us with our accounting and bookkeeping needs. We had been struggling for some time, and couldn't get anything done on time or get an accurate reading of our financial situation. Addison’s attention to detail and timeliness is what's really made the difference for us. He saved us a lot of time on our books and is always there when I need him!"

“Fortis Accounting Solutions has been an amazing partner. Our previous accounting firm made sure expenses were captured but by no means did they have the systems in place to drive our business forward. Once we began working with Fortis they helped clean up the bad habits from our previous accountants and worked closely with us to ensure the transition was seamless. Most importantly, Fortis took it upon themselves to really understand our business and how things flow on a monthly basis. It’s allowed us to treat them more as our internal accounting arm than an outside third party provider. I’ve never felt more confident about our accounting systems.”

“From the start of working together, Addison (who I work directly with) has been stellar! He responds to all emails and texts very quickly, especially when I need financials by a certain time. My old accountant was not as timely with documents and did not respond as quickly… so I was hesitant to work with anyone else. BUT, I was recommended to Fortis by a close friend and I’m really glad I reached out because its exceeded my expectations of what working with an outsourced accounting team should be.”
