Abstract: An e-commerce computer system electronically receives a selection of at least one product with at least one contractor service from a purchaser computer system. The e-commerce computer system automatically places a product code for the at least one product in an electronic shopping cart. The e-commerce computer system automatically places a service code for the at least one contractor service in the electronic shopping cart. The e-commerce computer system electronically completes a shopping cart transaction in electronic communication with the purchaser computer system.

Abstract: A certification computer system electronically receives contractor data from a contractor device. The certification computer system electronically stores the contractor data as certification data. The certification computer system automatically partially certifies a third-party contractor as a partially-certified contractor. The certification computer system electronically receives an electronic service request communicated from an e-commerce computer system. The electronic service request is based, at least in part, on a purchase of a product with a contractor service made in electronic communication with a purchaser computer system. The certification computer system automatically creates an electronic service work order. The certification computer system electronically communicates a certification request to the partially-certified contractor. The certification computer system automatically certifies the partially-certified contractor as a certified contractor.

Abstract: A certification computer system electronically receives contractor data from a contractor device. The certification computer system electronically stores the contractor data as certification data in a storage device. The certification computer system automatically certifies a third-party contractor as a certified contractor based, at least in part, on the certification data. The certification computer system electronically receives an electronic service request communicated from an e-commerce computer system. The electronic service request is based, at least in part, on a purchase of a product with a contractor service made in electronic communication with a purchaser computer system. The certification computer system automatically creates an electronic service work order based, at least in part, on the electronic service request. The certification computer system automatically selects the certified contractor from a plurality of certified contractors.

Abstract: A point of sale computer system is coupled to a global computer network. Barcode data scanned from a single barcode is electronically received at the point of sale computer system. The barcode data comprises a product code for at least one product and a service code for at least one contractor service. A product price for the product code is automatically added to a sales total. A service price for the service code is automatically added to the sales total. The service code is electronically received at the point of sale computer system from a mapping computer system. The service code is derived by the mapping computing system configured to map the at least one product with the at least one contractor service. A sale is completed for the sales total.
