Set decision gates
Define when integrations, SKU data, packaging instructions, and test orders must be approved. Assign an owner to each gate before the first transfer shipment leaves the current warehouse.
Reconcile the transfer
Compare the origin count, shipped quantities, destination receipt, and available-to-sell balance. Document how discrepancies will be resolved. Keep a fallback shipping plan until the new operation can handle ordinary orders and exceptions.
Write a controlled handover plan
List the stock count, shipment preparation, receiving confirmation, system tests, and order-routing changes needed for the move. Give each step an owner and an acceptance condition. Identify the decisions that depend on the outgoing provider, the incoming provider, and your own team. Keep the target date separate from the date everyone has confirmed. Review your actual commitments with the appropriate advisers before relying on a transfer assumption.
Review the operating tradeoff
Compare the effect on cost, inventory, and service scope together. Record the assumptions that would change the decision, not just the option that currently looks attractive. Ask for a baseline and one alternative so the consequences of the choice remain visible. A useful business case can be revisited when demand, product mix, or warehouse requirements change.
Use this question in your next meeting:
What must be confirmed before the next handoff can safely happen?
