Our Services & Expertise

Accurate accounting is vital to the health of your business

You can have the most talented managerial and sales team, but they will not be able to make your business successful without precise and professional financial management. The financial statements we provide for you can be used, among other things, to calculate your profit margin, keep your accounts payable and receivables up-to-date, and to make financing decisions. Moreover, the monthly financials can be read and compared against prior months, or years, and will help you determine changes in policy or whether a change in entity is required to respond to growth or liability coverage.

Napa Tax, Inc offers complete tax filing services to all our clients. We partner with Napa Bookkeeping Service to ensure seamless financials from monthly operations to tax return filings keeping your business in compliance with the tax code and abreast of your responsibilities to the taxing authorities.
