B2B is an abbreviation for "business-to-business." Imagine there are two businesses that work together, rather than directly with end consumers. That is, if, for example, there is a manufacturer of office paper, they sell their product not to individual people, but, say, to a large company that then uses this paper in its operations or resells it further.
To understand what B2B is in modern business, imagine a company that manufactures car parts. It does not sell these parts directly to you or me, but instead sells them to car manufacturers who are already assembling their cars and selling to end customers.
In today's world, B2B has a significant impact, as technology allows businesses to interact with each other more efficiently. For example, online platforms simplify the search for partners and the conclusion of deals. Thus, B2B is not just about selling products or services, but about building long-term business relationships that help companies develop and grow.
