Black Hills Accounting was founded by Aric Mackey to give small businesses and families the kind of careful, responsive accounting support usually reserved for larger companies.

Aric brings 15+ years of dedicated accounting and bookkeeping experience, backed by 20 years of financial management and operations, alongside a background as a software engineer. That combination means your books aren't just entered—they are built on systems that work. Bank feeds, automated imports, and software integrations get set up correctly so your ledgers stay clean month after month without manual grinding.

Industries We Know

Rooted in South Dakota, Serving Clients Nationwide

My wife, our three boys, and I moved to South Dakota to settle down, raise our family, and be an active part of this community. I am proud to bring my experience directly to my neighbors in Belle Fourche, Spearfish, Sturgis, Rapid City, and across the Black Hills.

We also work remotely with businesses and individuals across the country. Bank feeds, cloud accounting, secure file portals, e-signatures, and video meetings mean that clients in any of the 22 states we serve receive the same responsive service as a client down the street, with a real person who answers the phone.
