i doubt that you're going to find a source of *form* templates. a form is
only one element of an Access database. how any given form is designed, is
determined partly by the configuration of the tables/relationships in the
database, partly by the business process that the form will support, and
partly by the creativity of the developer. also, in Access, it's just as
likely that you'll enter data in one or more forms, and then create an
invoice *report* to print out a finished invoice.
if you're wanting some kind of form that you print out to be entered by
hand, you might try posting in an MS Word newsgroup, or googling.
