Taking the stress out of paperwork and everyday operations

Hi, I’m Tamantha “Tami” McInnis, founder of The Know-It-All, a female-owned, veteran-owned business offering practical support for small businesses, nonprofits, and individuals.

I help people bring order to messy systems, whether that means organizing records for tax season, cleaning up bookkeeping, or untangling day-to-day operations that no longer work smoothly. My approach is simple: understand what’s already in place, identify what’s causing friction, and build practical solutions that fit real life.

I combine hands-on experience with careful assessment and observation, not assumptions or one-size-fits-all fixes. The end goal is clarity, consistency, and systems that support both the work and the people doing it.

If things feel overwhelming or disorganized, you don’t have to sort it out alone. I’m here to help.

Why the name The Know-It-All?

Because decades of hands-on experience across multiple roles and industries, combined with advanced education and real-world problem-solving, have taught me how to recognize patterns quickly and translate what appears to be chaos into workable, organized solutions.

I help business owners and individuals move from from disorganized to structured, and from overwhelmed to in control.
