Need to generate an invoice

We need to generate an invoice for inventory removed from Tracmor.  We don't need the full accounting system behind it, just the ability to generate a PDF invoice and store the information in the database for reporting later.

I would suggest contacting BambooInvoice, it seems to be one guy with a php/mySql package that ONLY generates/stores an invoice.  It should be fairly easy to integrate with Tracmor and not have to reinvent the wheel...err... invoice.
