Services Overview

  • Apple MacBook with partially open lid and Apple Magic Mouse on a wooden desk with a black and white chair underneath.

    Tax Prep & Filing

    You’ve got multiple income streams, major life changes, or a growing business—maybe stock options, investment income, or a spouse’s side LLC. That kind of complexity deserves more than a once-a-year tax prep. We keep every return in sync—business, personal, and trust—so nothing slips through the cracks and every legal opportunity is captured. On top of that, we stay with you year-round. Quarterly check-ins, digital document collection, and timely reminders mean you’re never scrambling at tax time.

  • Three people working at desks with computer monitors in an office with large windows overlooking trees.

    Bookkeeping & Migration

    Maintaining clean books is the foundation for smart business decisions and audit-ready confidence, yet bookkeeping is the single most time-consuming distraction from growth. Whether you want a light review of your records, fully outsourced bookkeeping, or somewhere in between, we have a monthly plan that supports your business needs. If you’re still stuck in QuickBooks Desktop, we can manage your migration to QBO or Xero, ensuring your historical data is preserved and your setup actually works for how you operate.

  • Consulting & Advisory

    Most business owners pay thousands more in taxes than they should. We can review your entity setup and compensation structure to catch what others miss and often uncover $8,000 to $10,000 in annual savings. And when you want to go beyond saving on taxes, our outsourced CFO service delivers the next level of clarity. From cash flow forecasting to profitability reviews, you get the same strategic oversight larger companies rely on but without the cost of a full-time executive.
