Company (khevra, חברה) – for-profit entity which may engage in any lawful activity. Most companies limit the liability of their shareholders. In that case, the phrase "Limited" or the abbreviation "Ltd." must appear as part of the full name of the company. The term "B.M."/"BM" (בע"מ), literally: by limited liability/warranty, is usually translated as "Ltd." in English and pronounced "ba'AM" in Hebrew. Companies are governed by the Companies Act, 5759-1999 (חוק החברות, תשנ"ט-1999). Few sections are still in force from the Companies Ordinance [New Form], 5743-1983 (פקודת החברות [נוסח חדש], תשמ"ג-1983).
PLLC, Professional Limited Liability Company: some states do not allow certain professionals to form an LLC that would limit the liability that results from the services professionals provide such as doctors, medical care; lawyers, legal advice; and accountants, accounting services; architects, architectural services; when the company formed offers the services of the professionals. Instead those states allow a PLLC or in the LLC statutes, the liability limitation only applies to the business side, such as creditors of the company, as opposed to the client/customer service side, the level of medical care, legal services, or accounting provided to clients. This is meant to maintain the higher ethical standards that these professionals have committed themselves to by becoming licensed in their profession and to prevent them from being immune (or at least limit their immunity) to malpractice suits.
Sole Proprietorship – A sole proprietorship, also known as a trader firm or proprietorship, is a business firm that is owned and run by one individual. A sole proprietor may use a trade name or business name other than his or her name. Registration not required – In summary, biggest advantage is quick formation and low compliance. However, the biggest disadvantage is unlimited liability.
