Accurate Books. Better Decisions. Smarter Tax Returns.

As a CPA, I often see business owners come to me at tax time with disorganized books, or worse, NO books at all. One of the most common issues? Missing or incorrect equity accounts.

Without a properly maintained chart of accounts and equity tracking, your financial statements are incomplete, and your tax return can be inaccurate or even non-compliant.

Bad books cost you money. I’ve seen it repeatedly: businesses with poorly maintained books that resulted in incorrect tax filings. In many cases, I’ve had to correct the books and file amended tax returns, saving clients thousands of dollars in overpaid taxes or penalties.
That’s why I decided to offer professional bookkeeping services – not as an afterthought, but as an essential part of supporting your business success.

Bookkeeping is More Than Just Data Entry

It’s the foundation of financial clarity.

  • A clean Chart of Accounts ensures that your business income and expenses are properly categorized.
  • Accurate Equity Accounts track shareholder or partner contributions, distributions, and basis – critical for pass-through entities and correct tax liability calculation.
  • Well-maintained books make your tax return preparation smoother, faster, and more accurate.
  • Real-time financial visibility helps you make informed decisions and plan for growth.

What I Offer

I provide bookkeeping services tailored to small businesses and professional practices, with a strong emphasis on financial accuracy and compliance.

  • Cleanup and setup of QuickBooks or other accounting systems
  • Monthly or quarterly reconciliations
  • Custom chart of accounts designed for your industry
  • Correct tracking of owner’s equity, shareholder basis, and partnership capital accounts
  • Financial statement preparation
  • Direct coordination with tax preparation for full accuracy.

Built For Tax Accuracy

Many bookkeepers simply enter transactions. As a CPA, I go further. I connect your bookkeeping directly to your tax strategy to make sure your records support all deductions, losses, and basis limitations, especially important for S Corporations and Partnerships. Clean
books save time, money, and stress at tax time.

Free Yourself From The Chore

Bookkeeping is a chore, but it’s a chore you don’t have to do yourself. Let me take it off your plate so you can focus on running and growing your business. Whether you’re a startup, a professional, or a seasoned entrepreneur, clean books will give you peace of mind and the financial clarity to move forward with confidence.

Industry-Specific Bookkeeping Expertise

  • Construction & Trades (Electricians, Window Washers, Contractors)
    In construction, cash flow management and job costing are critical. I ensure your books properly track materials, labor, and subcontractor expenses. I also help establish accurate liability and equity tracking, which is often missing from DIY or outsourced bookkeeping. The result? Better financial clarity and tax compliance.
  • Healthcare Professionals (Doctors, Dentists, Specialists)
    Medical practices often face unique bookkeeping challenges like patient receivables, insurance billing, and complex expense categorization. I provide clean financial records designed to support growth and compliance, helping you focus on patient care while I handle the numbers.
  • Legal Professionals (Law Firms, Solo Practitioners)
    For law firms, accurate trust accounting, retainers, and client cost reimbursements are crucial. I provide bookkeeping that keeps you compliant with trust accounting rules while ensuring your equity and income accounts are properly maintained.
  • Entertainment & Show Business
    Artists, performers, and production companies often have irregular income and specialized deductions. I make sure your books reflect accurate expense tracking and equity reporting so your tax returns are maximized and audit-ready.
