What is the difference between company and firm? Do we say a law company? Are they different in the nature of the business? Thanks a lot.

I had always thought that, where both are incorporated entities, firms tend to be professions: law, medicine, accountancy. I see, however, that it also has another definition: A commercial partnership of two or more persons, especially when unincorporated. Well, that gibes somewhat with my image, since law firms and medical firms tend to be partnerships.

Law firms and architects' firms are usually partnerships, thus/and they aren't called companies.

But in many contexts, firm and company are both synonymous with business (unit):

firm
