An apparatus, program product and method validate service provider invoices for a customer to ensure that the waste disposal services associated with such invoices are both authorized to be performed and priced correctly in view of a contract between the customer and the service provider. Such invoice validation may be performed in connection with aggregating invoices from multiple service providers, paying those service providers, and generating on behalf of a customer a composite invoice that itemizes the waste disposal costs and services from multiple service providers. In addition, in some implementations a third party that assesses a customer's waste disposal services is permitted to share in the savings of a customer resulting from the assessment. A third party and a customer agree upon a cost reduction that the third party promises to realize for the customer, and to the extent the realized cost reduction for the customer exceeds the agreed-upon amount, at least a portion of the realized cost reduction that exceeds the agreed-upon amount is awarded to the third party. |
