Tax Prep + Planning
While a computer software program may help find deductions, there’s no substitute for the quality of service and advice you’ll receive from an experienced tax professional.
Tax Resolution
When people come to us, they often feel lost and discouraged. They’ve lived for so long in a constant state of stress and anxiety over their tax problems that they don’t even remember life without the constant threat of the IRS hanging over their head.
Small Business Accounting
Businesses of all shapes and sizes depend on accurate, insightful financial information to manage their day-to-day operations, capitalize on opportunities, and sustain profitability.
Virtual CFO
As your business prospers, a part-time Chief Financial Officer can help you develop financial plans to support business strategy, provide oversight of your accounting and administrative functions, and establish safeguards to mitigate risk.
QuickBooks
Although QuickBooks is very easy to use, it takes a bit of expertise and foresight to design the system for maximum benefit and effective control. Moreover, a new system set-up or conversion presents the opportunity to address long-standing gaps, inefficiencies, and annoyances. You don’t do it often, so you might as well do it right!
Advisory Services
We offer value added services that help you structure and manage your business to its best advantage. We help new businesses get off the ground and provide objective assessments of existing ones. We help you establish policies and procedures to protect vital assets and perform audits to ensure the integrity of your records.
