One Person Company is essentially a concept that involves the features of a Private Limited Company and the benefits of Sole Proprietorship. The Companies Act of 2013 governs it, and only one director and one member—who may both be the same person—are required to incorporate the organisation. Major companies like Amazon initially started by being OPC.
Even though there are lesser compliances, fulfilling the provisional requirements that come with such kind of incorporation is mandatory.
