About Inventory

DropStream keeps two views of inventory in sync: what your warehouse reports it has on hand, and what each sales channel believes is available to sell. Inventory flows in one direction — from warehouse to channel — and DropStream is the bridge.

To open inventory, expand Inventory in the left sidebar:

• Warehouse — what each warehouse last reported for each SKU.
• Channel — what DropStream has pushed (or will push) to each store, per channel SKU.

The flow

Warehouse → DropStream → Channel

1. DropStream pulls current stock from the warehouse on a recurring Smart Sync and, optionally, a recurring Full Sync. Both can also be triggered manually. See Smart Sync and Full Sync.
2. The warehouse reports its own figures for each SKU — typically on hand and available, and often a committed figure as well. DropStream uses the warehouse’s available quantity when the warehouse provides one; it does not recompute available from on hand.
3. DropStream pushes that available figure to every store that sells the SKU, translating warehouse SKUs to channel SKUs through the catalog and listings when needed.

DropStream is agnostic to the quantity the channel reports on its own — it only writes; it doesn’t read inventory from the channel.

How SKUs are mapped

Inventory uses the same mapping rules as orders:

• No listing for the SKU — the warehouse SKU is pushed to the channel exactly as the warehouse reported it.
• A listing exists — DropStream pushes the level under the channel’s storefront SKU, not the warehouse SKU. See How listings resolve SKUs.
• A bundle — the channel level for the bundle SKU is computed from its components. The lowest “bundles-worth” across all components is what gets pushed. See Bundle products.

Catalog records are optional for plain pass-through inventory; see When products are required.
