Basic auditor requirements

An active CPA license. Confirm their active status by contacting your state’s Board of Accountancy or by looking them up with the CPAverify tool.

Qualified auditors will share the following characteristics:Let’s say you’ve looked at a handful of auditors and audit firms and found several that meet the above basic requirements. Any one of them will likely do a decent job of analyzing your financial statements. However, if you choose an auditor based on the basics alone, you’re likely to end up with the wrong auditor for your specific situation. Do you want an auditor who will provide guidance on how to prepare financial statements, or are you confident in the statements issued by your finance department? Do you want someone who will advise your finance staff about disclosure requirements and accounting treatment of specialized transactions? Who will review your employee benefit plans? Who will assist with risk management? Is there additional information that you want the auditor to provide in their report? source ] Auditors may or may not provide these additional services, and the only way to find out if a particular firm will give you the support you need is to ask. Other potentially important factors include the following:The typical auditor hiring process includes requesting proposals from several different firms that will spell out the nature, limits, and other details of the firm’s auditing service. That means you’ll need to write a request for proposal (RFP) before your search for an auditor can make significant progress. Here’s what you’ll want to put in your RFP.Audit firms need to know a little bit about your company in order to put together a realistic proposal. Include basic background information such as your company’s business entity (e.g., corporation), the industry you’re in, the nature of the products or services you sell, your fiscal year-end date, your business locations, and the locations of various employees who will be involved in the audit process. You’ll also want to provide any specific requirements, such as the audit report deadline.Explain the exact nature of the services you want the audit firm to provide. For example, how many years’ worth of financial statements you want audited, if the audit report will be included in an SEC filing, and whether you want any additional services to be provided by the auditor. You’ll also want to describe any unusual circumstances that the auditor will encounter, such as uncommon types of transactions or assets that require specialized valuation approaches.Include the information that you expect each of the auditing firms to provide in their proposals. This will likely include details like the firm’s history, whether or not they have experience with your industry, copies of the firm’s most recent peer review report, which auditor will be performing the audit (and some information on this individual’s background), and any other information that’s particularly important to you.Finally, explain how you’ll select the winning audit firm. Firms will want to know how you’ll evaluate the proposals (i.e., if there are specific elements, such as the nature of the firm’s certification, that will be significant factors), the steps involved in the evaluation process, an approximate timeline, and any other information you consider pertinent.Once you’ve sorted through the proposals you received and have selected a firm, the chosen firm will send you a letter of engagement or another form of contract. You’ll need to review this document closely to confirm that everything the audit firm promised in their proposal is included. A reasonable letter of engagement will include the following details:Firing an audit firm can give your company a bad reputation by giving the impression that you have something to hide. That makes it imperative that you choose theauditor the first time, and the only way to accomplish this is through careful due diligence before you make your choice.
