Abstract: A system and method for offering promotional price discounts, rebates, and other offers to help service vendors improve the density of work sites for which they deliver services is disclosed. An electronic platform enables vendors that provide work site services to create and manage pricing schedules, rebates, and discount offers based on the geographic density of work sites. The vendor price lists can include a base price, and rebates and discounts from the base price increase based on the number of customer work sites within a given geographical area. The electronic platform enables vendors to advertise the geographically variable pricing schedules to clients, and to track customer patronage. The electronic platform allows customers to view and purchase vendor offered services from the discount pricing schedules, forward recommendations for vendor services to others, and submit requests for a discounted service to vendors.
