I have a website selling physical products that are modular. I have a stock of pieces that go into multiple different products. When a customer buys a particular product, I would like the individual pieces of that product to be removed from the inventory. I am looking for a shopping cart/inventory system that will work well for my needs. All of the shopping carts I have come across that have inventory setups only allow individual products, with no modular options. Does your cart offer this functionality or do you plan to add this functionality to your plugin? Thank You!
