While planning the incorporation of a business or the proliferation of its market presence, a critical decision needs to be made about the structural formation of the entity.
Partnership firms belong to similar echelons as that of a mainstream business model, where two or more persons come together to run a business and earn profits. In such a market pursuit, all associates are collectively responsible for orchestrating tasks and strategic collaboration related to the partnership. Such a Corporate framework originates from a contract between the two sides, which is called the articles of partnership. Every provision laid out in a partnership is dictated by the Partnership Act of 1932, be it registration or its termination.
Here, we present a curated list of 10 foremost partnership firms in India that are altering different sectors, including design and consulting, along with accounting and legal services, and are recognised for their impact, creativity, and collaborative models.
Top 10 Partnership Firms in 2025
1. Deloitte India
Deloitte India carries out its operations as a private partnership and is part of an international network of independent business entities. However, the global Deloitte firm does not operate under the partnership model; it is a consortium of legally distinct member firms. The defined operational areas of Deloitte India across India are aligned as a corporate organization, with partners acting as managing owners and retaining a stake in the local concern. This partnership plan arose from the collective legacy of local businesses, some of which were founded by Indian entrepreneurs, and it performs as an auxiliary within the globally scaled, yet separate, Deloitte chain. A significant component of the enterprises’ hierarchy is partner promotions, where directors are inducted into the partnership.
The firm really got its start way back in the late 1800s and early 1900s. That’s when a few local audit groups came together. Some of these had Indian founders, like S.B. Billimoria & Co.
