I have a version for Watkins that is almost done (about 98% there). Many parts are similar to Avon (Customer info/history, Invoices/Payments, Buisness cards/labels, etc.) It is slightly different from Avon in that it is not Catalog/Brochure based (more like Inventory based). And it has scheduling (Parties/Events/Shows/etc as well as Appointments).
The plan is to use it as a template for other direct sales Companies that are Inventory/Party type. Tupperware would probably work well (I don't know much about Tupperware even though all my juice comes out of a Tupperware product

). Even though they will be similar I want each version of MBA be customized for the particular company (much easier for Reps to learn/setup and use if its customized).
The Watkins will be up this month (probably as a Beta at first), download it when its available and see if it can be modified to work with Tupperware. If you think it can get back to me and we'll start working on getting one out for Tupperware.
Cheers,
Stan
