Katherine Bunschoten founder of Certum Solutions Accounting and Advisory for Businesses in the United States

Certum Solutions is a full-service business advisory and accounting firm based in Monroe, North Carolina, serving clients across the United States. Since 2010, we’ve helped small businesses, nonprofits, and growing enterprises simplify their back-office operations, improve financial clarity, and implement the right software to scale with confidence.

Unlike firms that offer one-size-fits-all packages, we take the time to understand your business, your industry, and your goals—whether you operate in manufacturing, construction, nonprofit, retail, or professional services. The result? Systems and processes that save you time, reduce errors, and give you the clarity you need to make smart, data-driven decisions.

Our Story

Certum started with a simple truth: most businesses aren’t broken they’re just buried under bad systems and surface-level support.

We saw founders stuck in the weeds, teams spinning their wheels, and businesses losing profit not from bad decisions but from a lack of insight. Bookkeepers didn’t go deep enough. Consultants didn’t stick around. And “solutions” just created more complexity. So we built something better.

Certum was created to bridge the gap between financial clarity and operational execution. We’re more than bookkeepers. We’re time auditors, cost accountants, process engineers, and software translators—on a mission to simplify growth for good businesses.

Our Mission

Not Just Your Bookkeeper—Your Growth Partner.

To empower business owners with the tools, insights, and systems they need to make confident decisions, improve profitability, and achieve sustainable growth, without the stress of managing day-to-day financial and operational complexity.

Whether you’re scaling fast or stuck in operational overwhelm, Certum is the strategic partner who gets your numbers in order and your business back on track.

Our team blends the expertise of fractional CFOs, controllers, and bookkeepers with advanced software implementation skills, offering solutions that go beyond standard accounting. From QuickBooks and Odoo ERP to Paychex, Avalara, Katana, Cin7, and more, we deliver custom setups, integrations, and training tailored to your workflows.
