We currently have a default Joomla/Tienda website.
We would like three extra features
1. at the time of checkout we would like to give the customer the option of requesting a quote, continue shopping or checking out and making payment.
2. import / export of products that works.
3. Member Login (b2b customers login to their own shop with products that we assign for them only)
a. we setup a shop for a customer(company)
b. we assign users to log into that shop
c. we assign products from our products list for that shop (ie. the customer has a defined set of products which they will only see, not the entire product list)
d. when the a user of the customer logs in, the first thing they see is their products
e. they then shop like normal and check out with some extra details in the check out.
