How does it work ?

Basically

1. Channel Advisor has a SKU record with lots of attributes
   1. One attribute is a TAG of the marketplaces it is live on - a single field with multiple comma delimited tabs
      1. Tags trigger rules to put the product live on the marketplace nominated > BDirect made these rules and included the TAGS to manage the multiple marketplaces.
   2. For each marketplace - there is attributes used for related prices
   3. The stock level available is shown on all marketplaces
   4. Each SKU can have stock in multiple marketplaces.

This is the channel advisor API requirements
