We Are A Southern California CPA Firm

Here at PlushStone Advisory, Tax, & Accountancy, we understand the breadth of knowledge and level of attention required to manage the financial issues your business will experience. We also recognize that as a business owner you don’t always have the expertise or bandwidth to understand or analyze your company’s finances in real time, making it difficult to know “is my business on track to achieve my goals.” As a trusted CPA firm located in Southern California, we provide a wide range of customized, accurate accounting services and analyses. From day-to-day bookkeeping and back office operations to making informed decisions about allocating your company’s resources, we’re ready to partner with you to help ensure your success. When serving our clients, we focus on four key areas:

  • A strategic tax plan to limit and manage tax liabilities
  • Strategic financial reporting, planning, and analysis to keep the business on the path toward achieving your goals
  • Regulatory reporting and compliance so you can focus on your business
  • Close, personal client and CPA relationships
