The weighted sales pipeline is a methodology for forecasting future sales revenue. The weighting is based on the likelihood of a deal closing, with deals that are further along in the sales process being given more weight. This approach can be useful for companies that have a large number of deals in their pipeline, as it can help them to focus on the deals that are most likely to close. The weighted sales pipeline can also help companies to identify when they need to add more leads into their pipeline, in order to hit their sales targets.
