B2G

A retail chain with a long history operating primarily as a bricks and mortar company, but 5 years ago they began to sell their products online. When they launched their online store, they created a separate division within their company that focused exclusively on online sales. While this strategy allowed them to get up and running online it seems it created some issues within the larger organization. For example, the bricks and mortar operation maintained their own inventory of products while the online division maintained a separate inventory. This presented an issue as the brick and mortar operation often has surplus inventory at the end of a season that just sits on their shelves until it can be shipped back to headquarters, but the online division will sell out of the very same products that the brick and mortar locations have a surplus of. To fix this situation, the company will overhaul operations to combine both online and brick and mortar operations to encourage sharing inventory, which will reduce overstock and increase profitability. This new strategy will streamline all sales so that they are tracked in the same system and allow customer's orders to be shipped directly from a store to their home or the customer can pick up the item in the store near their home.

Which term below represents this scenario?
