A sales pipeline is a visual representation of where each prospect is in the sales process. It’s important to know which stage you’re in just as a project manager would want to understand what stage they’re in managing a project.
Sales pipeline stages include:
- Lead generation
- Lead nurturing
- Marketing qualified lead
- Sales accepted lead
- Sales qualified lead
- Closed deal
- Post-sale
