A B2B sales pipeline is a structured process that manages sales opportunities from lead generation to deal closure in business-to-business (B2B) markets. The pipeline consists of stages such as lead qualification, discovery, proposal, negotiation, and closing. CRMs help visualize and manage pipelines by tracking deal progress, automating follow-ups, and forecasting revenue. A well-optimized B2B sales pipeline improves conversion rates, shortens sales cycles, and ensures efficient resource allocation for sales teams.
