'B2B sales' is short for business-to-business sales, which involves one company selling its goods/services to another company, rather than selling them directly to consumers. Indeed, generally speaking, B2B sales are more complex, require more people, and take longer than business-to-consumer (B2C) transactions.
Two variables are responsible for defining the type of B2B software-as-a-service (SaaS) sales processes: product complexity and product price. Depending on their combination, one can distinguish between three different types of B2B SaaS sales processes: self-service, transactional, and enterprise. The chart below represents the relationship between sales models, product prices, and product complexity.
