our story

Apparatus Solutions was founded in response to the specific accounting and human resources needs of small and medium-size impact organizations that struggle to find the right mix of expertise and value with their limited resources.

Starting in 2009 with only four employees and four clients, Apparatus Solutions launched with an entrepreneurial spirit of continuous learning and growth, flexible engagements, and a strong focus on delivering value.

Today, our team and client list are significantly larger, but the formula remains the same — using our expertise to deliver best practices, processes, and strategic thinking that bring exceptional value to all of our clients.

Whether you need financial or talent strategies, help with bookkeeping, creating an employee handbook, or all of the above, Apparatus knows the nonprofit sector and can tailor services to your specific needs and help your organization achieve success.
