For a new client I need to import lists of open customer and vendor invoices at the cutover date. I just need the invoice in receivables for when they make a payment afterward and do not want to post any transactions against product inventory. The only way I can think of is to create dummy products to use and just import one line item per invoice. Is there a better way? I can't find any documentation on how it should be done.

One line per Invoice works. Remember (1) you don't need a product on an Invoice line and (2) adding one doesn't affect inventory quantity anyway.
