Passion. Experience. Diligence.


Blue Rock Bookkeeping & Tax Co. was created with the focus of allowing start-up businesses an affordable bookkeeping experience. A veteran owned and operated company, Blue Rock Bookkeeping & Tax Co. or BRATCO as we like to call it, quickly began offering advice and providing our services to our active duty military and veteran community. Many of our service members volunteer their lives leaving their families and hometown's and states to embark on a journey that will put them through the ultimate test of survival, not only on the battlefield, but also in life. Our goal at BRATCO has been to share the information that we have and give our active duty service members and veterans the best possible opportunity that ensures that they are making the best financial decision. With this focus on our military community, BRATCO began to expand it's services to our public servants and religious organizations, while occasionally donating pro bono work for Churches.  

Blue Rock Bookkeeping & Tax Co. opened its doors in 2017. Since the very beginning the concept of providing affordable bookkeeping to smaller clients has been one of our main goals.  By allowing smaller companies access to larger company capability in the reconciliation and bookkeeping process, creates an opportunity for smaller businesses to grow at faster rates and get large business expertise in the process.
