After some review, this is a significant piece of getting the exchange to work correctly.

Basically, we will create a WP plugin for WooCommerce, and a Shopify app to start. We'll extend to other platforms later once the need arises.

These plugins will allow you to create a two-way sync between your store and our Exchange store. Which keeps all the orders, inventory, etc on your original store, while giving us the access to also capture the data for orders.

This will be a significant challenge to develop a store system that works with each store platform, but it will be worth it and has the potential to be really great.
