yes, we have demo site for you to verify the features.1. Do you have a demo this module? How tested this module before buy?
I will send you the demo site info to you shortly.
2. I have build a store with multi vendor addon. How I take payment
from my vendors? Any function when I use specific settings? Maybe
percent from vendors sell?
You can choose to to collect all payment, then pay to seller.
Or you can choose let seller to collect maney, then ask vendor pay you.
The payment and commision will be based on the contract between you and your vendors.
For 3 when you allow seller collect payment, it will only allow buyer to add items from same seller.
when you allow seller collect payment, it will only allow buyer to add items from same seller.
the module has control of the items added to cart, if it come from different, it will show message to prompt that the item comes from different seller/vendor, can not be in the one shopping cart.
feel free to ask if you have further questions.
