Warehousing

Warehouse

A stock location you plan and forecast as one pool.

Definition

A warehouse (stock source) is a physical or logical location whose on-hand inventory is planned together — your unit, a 3PL site, or FBA. Multichannel sellers usually map several sales channels into shared warehouses and keep FBA separate.

Worked example

Shopify, eBay and Amazon FBM share “3PL Midlands”. Amazon FBA is its own warehouse. Forecasts can still roll up by SKU while transfers move stock between sources.

Why it matters for replenishment

If channels silently share stock without a warehouse model, you oversell. If FBA is merged into own-warehouse maths, you double-count.

How OmniRestock uses this

OmniRestock uses one stock source per warehouse, keeps FBA separate, and forecasts across the model so POs and transfers stay coherent.

Common questions

Is a Shopify location a warehouse?

Often yes — map each location you buy for into a stock source.

Should FBA be a warehouse?

Yes, treat it as its own stock source with its own lead times and limits.

Can agencies see many warehouses?

Agency plans support portfolio views across client accounts.

Is a warehouse the same everywhere?

The idea is shared, but formulas and marketplace rules differ. Use the definition on this page for ecommerce replenishment.

Do I need software to track a warehouse?

A spreadsheet works for a few SKUs. Once you have many suppliers or channels, a replenishment tool keeps the numbers current.

Does OmniRestock change my live stock?

Not unless you switch Stock write or Purchase orders on for a connection. Drafts stay drafts until you confirm.
