Accounting & Assurance FAQS
Why are assurance services important for my organization?
Assurance services provide confidence in your financial information by independently verifying its accuracy and testing your internal controls. For management, investors, or board members, these services enhance trust and support informed decision-making. Welch LLP’s experienced assurance professionals identify risks, strengthen financial systems, and ensure compliance with regulatory standards.
What is the difference between an audit, a review, and a compilation (notice to reader)?
-An audit offers the highest level of assurance by thoroughly examining financial statements and internal controls.
-A review provides limited assurance through analytical procedures and inquiry.
-A compilation (notice to reader) involves assembling financial information into statements without providing assurance.
-Welch LLP helps determine the appropriate level for your organization based on compliance needs, lender requirements, and internal goals.
