Why Professional Accounting Matters for Your Business
When your accounting is done right, it changes how you run your business.
These are the results our clients care about most:
✅ Gain Back Control of Your Business - Know where your business stands at any moment. Clear, reliable accounting gives you visibility into cash flow, profitability, and trends so decisions are based on facts, not assumptions.
✅ Save Time Every Month – Stop spending hours trying to piece together reports or fix errors. With accurate accounting in place, your numbers are organized, up to date, and ready when you need them, without constant follow ups.
✅ Stop Losing Money to Mistakes and Missed Insights – Poor or delayed accounting leads to missed deductions, overlooked issues, and costly surprises. Reliable financial reporting helps you identify problems early and keep more of what you earn.
✅ Make Decisions with Confidence – From hiring to expansion to major purchases, your financial data supports smarter decisions. You move forward knowing your numbers are accurate and your risks are understood.
This is what dependable accounting looks like when it is built around your business, not just compliance. Call us today to discuss your accounting needs!

Outsourced Accounting & Advisory Services for Scaling Businesses
Bookkeeping | Financial Statements | Fractional Controller | Fractional CFO
Your business is growing, and so are your financial complexities. At Tehrani & Velez, LLP, a California Board of Accountancy licensed CPA firm, we offer Client Accounting Services (CAS) and Client Accounting & Advisory Services (CAAS) tailored to help businesses like yours scale efficiently.
While traditional bookkeeping firms provide basic transaction tracking, our team of Certified Public Accountants (CPAs) delivers higher financial oversight. With us, you get more than accurate books—strategic financial insights that help you make informed decisions and plan for long-term success.
Why Work with a CPA Firm Instead of a Basic Bookkeeping Service?
Many businesses start with a bookkeeper managing their cash-basis accounting in QuickBooks. But as you scale, you need more:
✅ Accurate Financial Statements – Properly structured reports for investors, lenders, and tax compliance.
✅ Technical Expertise – CPAs ensure your financials meet GAAP or accrual-based standards, making them decision-ready.
✅ Scalability Guidance – We help you transition from QuickBooks to NetSuite or other ERP platforms when the time is right.
✅ Advisory Services – Get strategic financial planning beyond daily bookkeeping—without hiring a full-time CFO or Controller.
With our CPAs on staff, we go beyond just keeping records. We interpret your financials, ensuring they support your company’s growth, profitability, and funding opportunities.
