Who We Serve
Sum Harmony Bookkeeping serves Appleton's vibrant business community with the care and attention every entrepreneur deserves. From the bustling shops along College Avenue to the professional offices throughout the Fox Cities, we understand what makes Appleton businesses thrive. Our team knows the local market, the seasonal rhythms, and the hardworking spirit that defines business ownership in northeastern Wisconsin.
We specialize in supporting the industries that keep Appleton strong. Medical and dental practices trust us with their complex billing needs. Restaurants and catering companies rely on us to track their daily operations. Construction contractors and home service providers count on us for project-based accounting. Whether you're a retail shop owner, a solo consultant, or managing a growing professional services firm, we speak your financial language.
Your business size doesn't matter to us, your success does. We work with solo entrepreneurs launching from kitchen tables and established companies ready to expand. Small businesses are the heart of Appleton, and we're here to help each one flourish. When you partner with Sum Harmony, you get more than bookkeeping. You get a local team invested in your growth, freeing you to focus on what you do best.


Why Choose Us
Appleton businesses choose Sum Harmony because we understand the Fox Cities. We've worked with manufacturers on Highway 41, healthcare practices near St. Elizabeth Hospital, and Main Street retailers who keep downtown thriving. From family-owned shops to growing contractors, we know what it takes to keep Appleton businesses financially organized. Our monthly bookkeeping and payroll management help you focus on what matters most: running your business.
Your business deserves more than one-size-fits-all bookkeeping. A manufacturing company tracking inventory needs different support than a service business managing contractors. That's why we customize our approach. Need QuickBooks setup but can handle daily entries yourself? Perfect. Behind on bookkeeping and need a complete clean-up? We'll get you back on track. We build packages around what actually helps your Appleton business succeed.
We're invested in the Fox Cities community and understand Wisconsin business requirements. From proper 1099 preparation for your contractors to managing accounts payable for seasonal fluctuations, we handle the details so you don't have to. When you work with Sum Harmony, you get a team that knows Appleton, understands your industry, and genuinely cares about helping local businesses grow stronger every day.
