Abstract: Electronic bill-presenting methods and bill consolidation methods are described. In one embodiment billing information pertaining to a labor-dependent service which has been rendered to a consumer is received into a host computer which preferably includes a processor. With the processor, the billing information is processed by auditing the billing information against at least one tolerance parameter to determine whether said billing information satisfies the one tolerance parameter. Processed billing information is provided into a computer-viewable format, wherein the consumer can view the processed billing information and authorize payment thereof. In another embodiment, a bill consolidation method comprises receiving into a host computer billing information pertaining to a plurality of at least one of a service or material which has been rendered or provided, respectively, to a consumer. The host computer has a processor and an interface device.
