BigCommerce Auto-Create lets you set Update Products on Auto-Create to create new Products in BigCommerce when you use the Upload option in Items Search.
Link-Only assumes your catalog is perfect and you just need to link Items to update. BigBusiness can set pricing and inventory on BigCommerce the minute it changes.
Auto-Create assumes you want to create new Products in BigCommerce for Items, too. Click Upload on Items and existing will be linked and new be added as possible.
WooCommerce ID can be added as a Column on your Items Search to show you Links.
WooCommerce ID helps identify the Products on your WooCommerce that are linked. Set Update Pricing and when the Item Price changes, the WooCommerce price changes.
You can Find, Sort, and Filter--enter a Hash mark for Not Equal To blank--to see IDs. If there is an ID, that is the Product that will get automatic updates for price or count.
Sites Controls help link your web stores to update inventory and pricing in real time.
If your company has multiple web stores, such as for retail and wholesale, these might need to immediately Update Pricing when your costs change, which BigBusiness does.
Sites Controls help you set Links from BigBusiness Items to your web store Products. Links help you manage which sites get which items' newest prices or inventory counts.
