17. Possible Strategies
• Use first Inventory Source which has enough inventory to ship all
order items
• Use Inventory Source which is cheapest way for the customer
and/or for the merchant
• Use Inventory Source which will balance the load between
sources, improve warehouse utilization
• etc
First by Priority Cheapest Warehouse Utilization etc

Shipping Rate Calculations
• Every source linked to the
carriers.
• Shipping Method available on
checkout are determined based
on the source carriers
• If there are more than one
shipping method needed to ship
all items, the price of the
shipping is a sum of all
shipping methods
• It is possible to use with the flat
rate shipment

Challenges
• Build CQRS architecture which will segregate Virtual Stocks
from Physical ones.
• Efficient Source Selection Algorithms. Algorithm which assigns
the particular inventory to the order item. “Minimal Delivery
Cost” should not impact checkout performance drastically.
• Performance. Sync vs Async
– Algorithm
– Synchronization with PIM and ERP
• Magento as a global inventory control system. Reservation API.
