By carefully tracking financial information, accounting firms are able to assure legal compliance and advise organizations on financial decisions. Businesses will typically work with these companies year-round but will have the most contact during the generation of quarterly or monthly reports and tax information. Many accounting firms offer [tax services](https://www.g2.com/categories/tax-services) and some firms specialize in taxes entirely. In addition to tracking financial information and providing tax services, accounting firms conduct large-scale examinations known as accounting audits. The purpose of an accounting audit is to systematically review an organization’s accounting process for inefficient, inconsistent, or suspicious procedures and transactions. Like [bookkeeping services](https://www.g2.com/categories/bookkeeping-services), many accounting firms will offer record keeping of a business's day-to-day financial transactions. Show More
