The majority of companies collaborate with other companies, consumers, suppliers, and other stakeholder networks. In developed economies, more than half of all transactions are between companies. About half of a company's costs come from purchasing products and services. Most e-commerce is between companies. Marketing to corporations is the act of selling goods or services to companies that then resell those products or use them for operational purposes. The number of customers is not limited to companies - educational institutions, government agencies, and non-profit organizations can also buy goods or services.

Corporate marketing is the strategy a company uses to promote its overall brand, values, and image rather than focusing only on individual products or services. The goal is to create a strong identity that builds trust with customers, investors, employees, and the public. It includes activities like branding, public relations, sponsorships, corporate social responsibility, and communication campaigns. Unlike product marketing, which targets sales of a specific item, corporate marketing highlights the company’s reputation, culture, and long-term vision. A strong corporate brand can make products more appealing, attract talent, and strengthen relationships with stakeholders. In today’s competitive market, effective corporate marketing is essential for positioning the company as credible, responsible, and reliable in the eyes of the wider audience.
