Print shop ordering system plugin?

I have been searching for a WordPress plugin for a small printer (brochures, stationery, envelopes etc) to handle customer orders of existing products. They only want an ordering system, possibly order tracking, but not ecommerce. Client login required and the clients only see and order their own print products (letterheads, envelopes etc).

I keep turning up full blown ecommerce options or nothing even remotely useful to the point where I’m wondering if I’m using inappropriate search terms.

Any suggestions appreciated.
