Abstract: The present invention is a central invoicing system. Payors and invoicers can use the central invoicing system by connecting to it by a network, such as the Internet, and using an interaction device, such as a personal computer with web browsing software. Payors can create, on the central invoicing system, a list of invoicers from whom they wish to receive invoices. The system sends invitations, including a user name and password, to the selected invoicers to enroll with the central invoicing system. The system provides invoicers with a facility to enroll with the central invoicing system over the Internet. Payors can also customize the format of the invoices they are to receive from the selected invoicers. The central invoicing system stores each payor's particular invoicing format on a server. The system allows an invoicer to connect to the system through the Internet to create invoices. The invoicer can then submit that invoice to the payor through the system.

Abstract: Apparatus for adjustably attaching roof panels to the sidewalls of an enclosure and for securing the pitch of the roof panel with respect to the sidewalls after it has been established is disclosed. The apparatus includes a header support member which is placed on top of the sidewall and has a longitudinally extending pocket therein. A header arm having a longitudinally extending yoke at one end thereof is received in the longitudinally extending pocket in the header support member. After the roof pitch has been established by rotating the yoke portion of the header arm within the pocket in the header support member, the header arm is fastened to the header support member to secure the roof pitch. The header support member and the header arm each have a pocket formed therein which is filled with insulating material providing a thermal break within each of these components.
