Warehouses are useful when a growing business can no longer depend on one-off trips to keep every storefront supplied. The Steam description explicitly mentions importing products from the harbor and distributing them through a network of warehouses. It also mentions Logistics Managers and Purchasing Agents for larger operations.
What a warehouse should solve
Use a warehouse to make stock movement predictable. Decide which businesses it serves, which products belong there and how often the network needs replenishment. If it does not reduce travel or prevent stock interruptions, it may be an expense without a clear job.
A staged logistics plan
List the receiving businesses
Write down each storefront and the stock it needs. Start with the locations that already have reliable demand.Define the supply route
Choose the import or purchase point, the warehouse and the delivery route. Keep the first network small enough to troubleshoot.Add staff when the network justifies it
The official store description names Logistics Managers and Purchasing Agents as part of larger operations. Do not hire ahead of a real logistics workload.
Exact capacity, delivery timing and staffing costs need current-build testing. Keep those values in the business requirements database and note the patch beside each result.
