Abstract: A website including a search web page configured to search for invoices and to display a web page with at least one found invoice summary. There is a link between the at least one found invoice summary and an invoice which, when activated, displays a web page with an invoice including at least one line item for an advertisement in a publication, and a link between the at least one line item and a tearsheet for the advertisement which, when activated, displays a web page with the tearsheet along with metadata regarding the tearsheet.

Abstract: A system useful for interrelating and storing advertisements, tearsheets, and invoices. A receiving portal receives electronic files representing the pages of a publication, electronic records of advertisements, and electronic records of invoices. An engine responsive to the receiving portal is configured to electronically interrelate and store the electronic files representing the pages of a publication, the electronic records of advertisements, and the electronic records of the invoices. A search routine is configured to search for invoices and/or tearsheets. A display routine is configured to display found invoices and tearsheets in a way that interrelates an invoice line item with a tearsheet typically by displaying the invoice with a link to the tearsheet which is displayed when the link is activated.
