What OneSource Accounting & Tax does
OneSource Accounting & Tax is a privately held, for-profit professional services firm headquartered in Washington, United States, that has operated continuously since its founding in 2004. The firm operates with a micro-scale headcount of 1–10 employees and is not publicly traded. Its stated service scope is the delivery of tax preparation, accounting, business consulting, and QuickBooks-focused services to both individuals and businesses, positioning it as a local generalist bookkeeping and tax practice rather than a specialized or technology-platform business.
The firm's underlying technology stack centers on Intuit's QuickBooks ecosystem, which is used as the primary bookkeeping platform for its small-business clients; no proprietary software, AI/ML systems, or differentiated technology components are disclosed. The publicly listed website (1sourceaccounting.com) currently renders as a verification/loader page with no substantive content, marketing material, or service-detail disclosures, indicating a minimal digital presence. No information is available on the firm's internal product roadmap, integrations, API surface, or data assets.
The business model is that of a traditional fee-for-service accounting practice: revenue is generated through hourly billing or fixed-fee engagements for tax preparation, bookkeeping, advisory, and QuickBooks consulting work delivered to a mix of individual taxpayers and small-business clients. There is no evidence of subscription pricing, software licensing revenue, channel partnerships, or non-service revenue lines; correspondingly, there are no disclosed customer logos, no segment-level revenue splits, and no growth or hiring signals in the input data.

OneSource Accounting & Tax competitors and assessment
Company assessmentBroad incumbents
- BDO USA: Top-tier U.S. accounting firm offering tax, accounting, and advisory to mid-market and SMB clients. Competes for the same Washington-region SMB tax/accounting work but as part of a global portfolio.
- H&R Block: National consumer and small-business tax preparation chain with adjacent bookkeeping services. Competes primarily in the tax preparation portion of OneSource's offerings.
- CBIZ: Large U.S. provider of accounting, tax, and advisory services to SMBs and mid-market. Overlaps heavily in tax and bookkeeping services though at much larger scale and broader geography.
- Intuit ProConnect / QuickBooks Live: Intuit's own bookkeeping and tax services delivered on top of QuickBooks. Directly overlaps with OneSource's QuickBooks-centric value proposition and represents both a partner channel and a competitor.
- RSM US: Large U.S. accounting firm focused on mid-market with tax, accounting, and consulting services. Adjacent in SMB/mid-market accounting services but broader in scale and capability.
Direct peers
- Padgett Business Services: Network of small accounting/tax/consulting franchises serving SMBs with bookkeeping, tax, payroll, and advisory. Closely comparable in size, target market, and bundled service model to OneSource Accounting & Tax.
- 1-800Accountant: Virtual accounting and tax services firm targeting SMBs and individuals with bookkeeping, tax, payroll, and advisory. Comparable in target market and service mix, though distributed rather than local.
- Bookkeeper.com: Online bookkeeping and accounting service for small businesses, offering monthly bookkeeping, tax prep, and payroll. Direct SMB accounting-services competitor.
Emerging players
- Pilot: Tech-enabled bookkeeping, accounting, and CFO services primarily for startups and SMBs. Competes for the same QuickBooks-using SMB bookkeeping customers with a more scalable, software-augmented model.
- Bench (now part of Thread Bank): Tech-enabled bookkeeping service for SMBs pairing software with dedicated bookkeepers. Same bookkeeping/tax customer base as OneSource but delivered through technology-enabled model.
