Purchase Orders vs. Inventory Transfers

Your Seattle store is down to four units of a bestseller. Your Austin warehouse has sixty of the same SKU sitting untouched. The instinct is to reorder from your supplier — but you already own enough stock, it's just in the wrong place. That's the exact situation a purchase order and an inventory transfer solve differently, and picking the wrong one either wastes cash or doesn't fix the shortage.

Definitions

A purchase order buys new stock from an outside supplier. It creates inventory that didn't exist in your business before — cash goes out, and stock comes in from somewhere you don't control.

An inventory transfer moves stock you already own between two of your own locations. No new stock is created, no supplier is involved, and nothing new enters your business; you're just relocating what's already yours. Shopify's own transfer tool, under Products → Transfers, handles this specifically: pick an origin and a destination location, specify quantities, and the receiving location gets three actions once the shipment arrives — Accept, Reject, or Cancel. The transfer mechanics themselves, including multi-location setup, are covered in managing inventory across multiple Shopify locations.

When to transfer instead of order

Transfer when the shortage is a distribution problem, not a supply problem — you have enough stock company-wide, it's just sitting at the wrong location. A transfer is also typically faster than a new PO, because it skips your supplier's lead time entirely; you're moving stock that's already produced and already yours, not waiting on someone else to make more.

It's also cheaper in the short run: no new purchase, no new cash outlay, just the cost of getting the stock from one of your locations to another.

When a transfer doesn't fix it

A transfer only works if the stock actually exists somewhere in your business. If every location is low on the same SKU, there's nothing to move — a transfer just relocates a shortage, it doesn't create supply. At that point you need a purchase order, full stop, regardless of how good your transfer process is.

Worth remembering too: moving stock between locations still costs time and freight, even though it skips the supplier's lead time. For a low-value SKU or a long distance between locations, that cost is sometimes closer to a new order than it looks at first glance.

Deciding fast

Two questions settle most of these in under a minute:

Running both tools from one place, rather than two separate apps, is part of why StockCue pairs purchase orders (Starter plan and up) with stock transfers between locations (Scale plan) — the decision above stays a business question, not a "which app do I open" question.

Frequently Asked Questions

What's the difference between a purchase order and an inventory transfer?

A purchase order buys new stock from an outside supplier. An inventory transfer moves stock you already own between two of your own locations. One brings new inventory into the business; the other just relocates what's already there.

When should a stock shortage be solved with a transfer instead of a new order?

When the shortage is about distribution, not supply — you have enough of the SKU somewhere in the business, it's just at the wrong location. A transfer is usually faster than a new purchase order because it skips your supplier's lead time entirely.

Does a transfer help if every location is low on the same SKU?

No. A transfer only relocates stock that already exists in your business. If every location is genuinely short, there's nothing to move, and you need a new purchase order regardless of how well your transfer process works.
