Chain O' Lakes Applications and Programming Services is based in Rapid City, Michigan, in the middle of the Elk River Chain of Lakes.
We build software that small businesses actually use, from internal tools and customer portals to full subscription platforms with billing, maps, and reporting. Years of hands-on work in internet service, networking, and business operations means we understand the systems behind the software, not just the code.
