Abstract: A group-based lead management platform can efficiently manage and score leads for suppliers such as hotels. The platform can manage leads in a separate layer above the underlying systems that controls inventory. The platform can automatically adjust lead scoring strategy based on the pace of inventory booking relative to plan. The platform can take into account historical booking patterns of a supplier in generating lead scores. The platform can auto-assign or estimating one or more events associated with a group booking to one or more units of event space. The platform can provide a lead score in a user interface that also provides a visual breakdown of the scoring strategy components weighting the score.
