If I push the retail price to my Shopify store, can I then manage the markup within ChannelApe before it’s pushed out?
Sure, that is one of the key features of ChannelApe. You can pull in the inventory data from your supplier and then apply a markup or a markdown to the pricing before sending out to a new marketplace.
You can also decide to use either the wholesale price and mark your price up or use the retail price from the supplier and mark the price down. Either way, ChannelApe can handle this.
