Who We Serve
Sum Harmony Bookkeeping serves Bismarck's hardworking business community with dedication and local expertise. From solo entrepreneurs launching their dreams to established companies expanding across North Dakota, we understand the unique spirit of doing business in our capital city. Our team knows what it takes to succeed here, where prairie determination meets modern opportunity.
We bring specialized knowledge to Bismarck's core industries. Medical and dental practices trust us to handle their complex billing while they care for patients. Local restaurants and catering services rely on our expertise with inventory and cash flow. Construction contractors building our growing city count on us for job costing and project tracking. Professional service firms throughout downtown know we speak their language.
Whether you run a retail shop on Main Avenue, operate a home service business reaching across Burleigh County, or manage a growing commercial enterprise, we're here for you. Small businesses are the heartbeat of Bismarck, and we believe every entrepreneur deserves professional financial support. When you partner with Sum Harmony, you gain more than bookkeeping. You gain the freedom to focus on what you do best.


Why Choose Us
Bismarck businesses choose Sum Harmony because we understand North Dakota's capital city. From energy companies managing complex payrolls to Main Street retailers tracking inventory, we've helped local businesses stay financially organized for years. We know the unique challenges of doing business in Bismarck, whether you're a contractor working the Bakken fields, a healthcare practice serving the community, or a growing company near the Capitol.
Your bookkeeping needs aren't one-size-fits-all. A construction company preparing dozens of 1099s has different requirements than a restaurant managing daily cash flow. That's why we customize our services around what actually helps your business. Need weekly payroll but only monthly bookkeeping? Perfect. QuickBooks setup with ongoing support? We'll make it happen. You get exactly what your Bismarck business needs, nothing more, nothing less.
We focus exclusively on North Dakota businesses and stay current with state requirements and tax laws. Our team understands Bismarck's economy and the industries that drive it. When you partner with Sum Harmony, you work with professionals who know the difference between managing books for an ag business versus an oil service company. We're here to help Bismarck businesses maintain financial harmony and grow with confidence.
