From solo entrepreneurs launching their dreams to established small businesses shaping our town's character, we understand the unique spirit that drives Plymouth forward. Our team knows what it takes to succeed here, combining personalized service with the financial precision your business deserves.
We specialize in Plymouth's core industries. Medical and dental practices trust us with their complex billing needs. Local restaurants and catering companies rely on our expertise in managing fluctuating costs and seasonal revenues. Construction contractors and home service providers count on us for project tracking and cash flow management. Professional service firms appreciate our understanding of billable hours and client trust accounts.
Whether you're a retail shop owner on Main Street, a growing commercial services company, or a field service professional working across the region, we're here to simplify your financial life. Every Plymouth business has a story, and we believe each one deserves expert bookkeeping support. When you partner with Sum Harmony, you gain more than a bookkeeper. You gain the freedom to focus on what you do best.


Why Choose Us
Plymouth businesses choose Sum Harmony because we understand what it means to be local. We know the seasonal rhythms that affect your cash flow, the suppliers you work with, and the growth patterns unique to our community. From Main Street retailers managing inventory to service professionals tracking billable hours, we've helped Plymouth businesses stay financially organized for years.
Your bookkeeping should match your business needs, not the other way around. Maybe you need weekly payroll management but only quarterly bookkeeping reviews. Perhaps you're drowning in receipts and need a complete clean-up before tax season. Or you're ready to streamline with QuickBooks but don't know where to start. We create packages that fit your actual needs and budget, so you're never paying for services you don't use.
We stay current on state regulations and tax requirements that affect Plymouth businesses. Our team handles everything from accounts payable and receivable to 1099 preparation with the same careful attention. When you work with Sum Harmony, you get more than bookkeeping. You get a partner who's invested in your success and understands what it takes to thrive in Plymouth's business community.
