Split the "invoice" report design into multiple bands. The footer is a page footer band. The top part "your details here" and "invoice' is a report header. The Date, Inv No, Inv address can be a page header, or if you don't want it on each page, make it a child band of report header. The Qty, Product Code etc could be a group header. The actual "details" will be a usual detail band and will fill the remaining space of the page. All the bands, except "details" will have set band heights (don't stretch vertically).
