01 / BusinessWhat really needed solving
The multichannel problem does not end at connecting APIs. An order changes inventory, logistics, billing and collection. When each channel interprets those changes separately, people have to reconstruct the same operation over and over. The described hub brings those dependencies together around Books and Inventory.
02 / DesignWhy this structure matters
The key design decision is to put B2B/B2C logic in a shared layer rather than maintain different rules per channel. Six automations cover parts of the same operational journey, while dashboards expose the outcome. Integration, execution and visibility become one system rather than isolated projects.
