Bart & Don:
I would not mind having some help, advice or even just moral support! I have no illusions that this ecommerce module will have as much 'stuff' in it as the 3.x version, but that is the point. I have used the 3.x version for several years, and it is amazing how many things I have had to remove and add to the current system for my customers. 3.x is usually easy to fix, but it is always a hack.
Right now I am working on the admin pages. One thing I want to ensure is that the vendor should use the site to place orders if the customer calls by phone (80% of the time in this case). Another feature that I need to support is the ability of customers to add their own products (private products), which the vendor will source.
Gotta run for now, more later.
