Accounting for Libraries & Nonprofits

Bookkeeping & Financial Reporting designed for Mission-Driven Leaders

When library and nonprofit leaders have financial clarity, they lead with confidence.

That clarity strengthens community partnerships and fuels local mission impact.

Tired of old archaic tools and processes?

Ready to feel in control of your organization’s finances?

Who we work with

  • Libraries may operate with lean teams, but their impact is anything but small. We partner with public and academic libraries to provide bookkeeping, grant tracking, audit support, and financial reporting tailored to their unique funding structures. Our goal is to bring financial clarity and modern systems to support the vital work libraries do in their communities.

  • Nonprofits operate with purpose—and often under pressure. We help mission-driven organizations stay financially strong with bookkeeping, compliance support, grant reporting, and outsourced CFO services. Our solutions are designed to bring transparency, strategy, and confidence to your financial operations, so you can focus on impact.

    “Lumos has added the comprehensive professionalism that our non-profit was lacking, with attention to detail, use of the latest programs to streamline our finances, and responsiveness that shows a true understanding of our mission. ”
