A backorder is an order a store accepts for an item it doesn't have in stock, with the plan to ship it once new inventory arrives. When an order status says "backordered," the store took your order, nothing has shipped yet, and the wait is for a restock rather than for picking and packing.
The order is real. Whether you've been charged depends on the store's policy, and the only open question is how long the wait runs. The rest of this page covers what happens to the order next, how a backorder differs from out of stock and preorder, why stores accept backorders at all, and what good handling looks like on both sides.
What happens to a backordered order
The order sits in the store's queue until the restock is received. From there it follows the same path as any other order: the warehouse checks in the new inventory, picks and packs your item, and hands the package to the carrier. The shipping confirmation arrives at that point, not before.
If you ordered several items and only one is backordered, the store may split the order and ship the in-stock items first, or hold everything until the last item lands. The confirmation email should say which, along with a ship estimate and whether your card has been charged. Those three details are the ones to look for.
"Backordered" is also different from "processed." A processed order has been accepted and is moving through picking and packing with stock on hand. We cover that status separately in what "order processed" means.
Backorder vs. out of stock vs. preorder
The three labels describe three different inventory states, and stores mix them up more often than they should.
- Out of stock. The store has no inventory and has stopped taking orders for the item until it returns. There is nothing to buy right now.
- Backordered. The store has no inventory but is still taking orders, queued to ship when the restock lands. The product exists and has shipped before; the gap is temporary.
- Preorder. The product hasn't launched, or hasn't left the factory yet. You're buying against a first production run, and the ship date is tied to the launch rather than to a restock.
For a shopper, "out of stock" means no order to place, "backordered" means a wait of days or weeks on a known product, and "preorder" means a wait until launch. Some stores accept "backorders" on items that have never shipped at all. That is a preorder and should be labeled as one. If you sell preorders, how preorders work covers the mechanics.
Why stores backorder products
A store accepting backorders is making a calculated bet: that the customer would rather wait than walk away. A few reasons it happens:
- Demand spiked faster than the restock cycle. A product trended, a press hit landed, or peak season pulled volume forward.
- Supply chain delay. A shipment from the manufacturer is late: container delay, customs, factory bottleneck. This is the gap a supply chain continuity plan exists to cover.
- Forecast missed. The store underbought on the last purchase order and ran through inventory ahead of schedule.
- Production capacity is the bottleneck. Especially for handmade, custom, or specialty products where the supplier can only make so many per week.
The store gets a few things out of backordering: kept revenue that would have walked, demand signal for the next purchase order, and a way to keep the SKU live on the site instead of dark.
What good backorder handling looks like
From the buyer's side
A buyer-friendly backorder gives you four things:
- A specific ship date or window. "Ships in 2–3 weeks" is acceptable. "Soon" is not.
- A clear charge policy. Either the card is captured at order time, or authorized but not charged until ship. Both are fine. Being silent about which is not.
- A cancel option without hassle. If the wait stretches past the original window, a one-click cancel is reasonable.
- A status update if the window slips. Most backorder frustration is about silence, not about the wait itself.
If a backorder confirmation arrives without a ship date, that's the first thing to email the store about.
From the store's side
If you sell online, backorders are a customer-trust decision more than an inventory one. The framework worth running:
- Show the wait time on the product page, before checkout. Surprises after the order is placed cost more than the lost conversion would have.
- Hold charging until ship if your platform supports it. Captured-at-order money creates pressure on the back end that's avoidable.
- Track cancellation rate per SKU. If a backordered SKU is cancelling above 15% during the wait, the wait is too long or the communication is too thin. Both are fixable.
- Pick the cutoff between "backorder it" and "kill the SKU." Sometimes the right answer is to stop selling the item until inventory's back and avoid the support load entirely.
How backorders affect fulfillment
On the warehouse side, backorders fragment the order fulfillment flow. A two-item order where one is in stock and one is backordered has two possible paths:
- Split shipment. Ship what's available now, ship the backordered item later. Customer gets the in-stock item fast; you eat the extra postage on the second box and take on the damage risk of a second package in transit.
- Hold for full ship. Wait until everything is in inventory, ship once. Customer waits longer; postage is cheaper.
Neither is universally right. A high-AOV order where the wait is two weeks usually calls for split shipment. A low-AOV order where the wait is three days usually doesn't. Your 3PL or warehouse system needs the rule encoded, because a manual decision on every order doesn't scale. FIFO applies here too: backordered orders ship in the sequence they were received, so no customer waits longer just because they ordered earlier.
If a 3PL runs your warehouse, ask how it handles a partial-stock order before you need the answer. The answer you want is a split-or-hold rule set per SKU ahead of time, with the 3PL applying it from a live inventory count, so nobody is deciding order by order once volume picks up. Simpl's ecommerce fulfillment service includes real-time inventory visibility, so you see a SKU hit zero when it happens instead of after the backorder emails start.
Legal considerations
In the U.S., the FTC Mail Order Rule requires retailers to notify customers of shipping delays exceeding the stated delivery window and offer the option to consent to the delay or cancel without penalty. Backorders that stretch without updates can trigger this requirement, so the ship-date estimate on the product page is both an ethical expectation and a legal one.
How to reduce backorders
If backorders are happening more than you'd like, the fix is upstream:
- Forecast inventory against rolling 4-week sell-through. Reorder points based on a static lead time miss demand shifts.
- Build supplier redundancy. A single supplier with a long lead time is the most common backorder cause for small brands.
- Set inventory floor alerts at 4 weeks of cover, not 2. That buffer absorbs supply delays before they become a backorder.
- Watch hero SKU velocity. Your top 10 SKUs cause most of your backorder pain. Treat them differently from the long tail.
Avoiding every backorder is expensive in working capital. The goal is to backorder by choice rather than by surprise.
Frequently asked questions about backorders
What does backordered mean?
Backordered means the store accepted your order for an item it does not have in stock right now. Nothing has shipped. The order is queued and ships once the restock arrives, so the wait is for inventory rather than for picking and packing.
What is the difference between backordered and out of stock?
Out of stock means the store has no inventory and has stopped taking orders for the item. Backordered means the store has no inventory but is still taking orders, each one queued to ship when the restock lands. One label closes the sale; the other keeps it open with a wait attached.
How long does a backorder take?
There is no standard backorder length. It depends on when the store's restock arrives, and the merchant should state that as a specific window, such as "ships in 2 to 3 weeks," rather than "soon." If the confirmation carries no ship date, that is the first thing to email the store about. A wait tied to a product launch rather than a restock is a preorder, not a backorder, and should be labeled as one.
Can I cancel a backordered order?
Before the item ships, whether you can cancel is set by the store's policy. Check the order confirmation, then email the store with your order number. A buyer-friendly policy lets you cancel without hassle if the ship window slips past the original estimate. In the U.S. there is also a legal floor for most merchandise ordered online, by mail, or by phone: under the FTC's Mail, Internet, or Telephone Order Merchandise Rule, a covered seller that cannot ship within the window it stated, or within 30 days if it stated none, has to notify you and offer the choice to wait or cancel for a prompt refund. The Rule has a short list of exemptions, such as C.O.D. orders and subscriptions after the first shipment.
Why is a product still listed as in stock if it is actually backordered?
Usually because the store's inventory count has not been updated, or the platform is not showing the backorder status clearly. If you ordered expecting fast shipping and got a backorder notice instead, that is a fair reason to ask for a refund.
