Productive work and the success of any business directly depends on the professionalism and quality of accounting. Observing the deadlines for filing reports, timely and correct payment of taxes, correct charges, timely posting of primary documentation, drawing up declarations are conditions that have a direct impact on the fruitful work of all departments of a company or enterprise.
Accounting allows the company to avoid misunderstandings with the authorities and representatives of tax services and prevent issuing fines and possible penalties.
Suppose we start to think about accounting companies. In that case, the most famous accountants are The Big Four - the nickname used to refer collectively to the four largest professional services networks in the world: Deloitte, Ernst & Young, KPMG, and PricewaterhouseCoopers. The four structures are often grouped for several reasons; they are each comparable in size relative to the rest of the market, both in terms of revenue and workforce. They are each considered equal in their ability to provide a broad scope of professional services. The Big Four offers audit, assurance, taxation, management consulting, actuarial, corporate finance, and legal services. These four networks conduct a significant majority of public companies’ audits and many audits of private companies.
