In broad terms, a vendor is any business or individual that supplies products to consumers. In small business, people use the term “vendor” to describe companies that supply other businesses with specific goods or services. If you run a garment manufacturing company, for example, you might do business with vendors that sell textiles and sewing notions. If you’re a freelance accountant, you might do business with a software provider of accounting programs, such as QuickBooks. Businesses typically use purchase order software to track vendor purchases. Your small business can be a vendor of products or services as well, especially if your clients are other businesses. As a vendor, you can find new clients at industry-related trade shows and other networking events.
