Services
Audits & Reviews
Briscoe Burke & Grigsby provides comprehensive audit and review services to verify financial accuracy and regulatory compliance. Our CPAs examine internal controls, test transactions, and issue formal opinions to satisfy stakeholders. These services help businesses maintain transparency with investors, banks, and government agencies while identifying operational improvements. Our systematic approach ensures financial statements reflect true business performance.
Cash Flow Management
Our cash flow management services develop strategic projections to prevent liquidity crises. We create short- and long-term forecasts, optimize credit access, and implement collection policies. This helps clients maintain payroll obligations, manage debt, and capitalize on growth opportunities. Our analysis transforms erratic cash positions into predictable financial planning frameworks.
Tax Preparation
We prepare federal and state tax returns for businesses and individuals while identifying legal deductions. Our team analyzes complex tax scenarios to minimize liabilities and maximize refunds. Electronic filing ensures timely submissions, while payroll withholding optimization returns cash flow to clients immediately rather than as post-filing refunds.
QuickBooks Services
Our QuickBooks specialists provide software setup, training, and ongoing system optimization. We help businesses maintain accurate digital records through customized chart of accounts and reporting structures. Regular tune-ups prevent data integrity issues while training empowers clients to leverage software capabilities for daily financial management.
Internal Controls
We evaluate and strengthen financial control systems to prevent fraud and operational inefficiencies. Our assessments focus on duty segregation, transaction authorization, and asset protection protocols. Documented procedures ensure business continuity while regular reconciliations maintain financial accuracy across accounting cycles.
