Out of stock after a sale on eBay: your options, the defect and how to stop it happening

What should you do when an item is out of stock after a sale on eBay?

When an item is out of stock after a sale on eBay, message the buyer straight away, explain plainly, and offer the options you can really deliver. Then act on their answer the same day. Speed matters more than anything else here: a buyer told early has choices, while a buyer who finds out after the dispatch date has passed has only a grievance.

It also helps to know the cost before you choose. eBay's order cancellation policy says that cancelling an order because the item is out of stock results in a transaction defect. Defects count towards your seller level, so the way you handle the next hour has a cost that lasts months.

What are your options, in order?

Work through these in order. Each one costs less than the next.

1. Find the stock. Check other locations, returned items in good condition, or another supplier who can send the same item within your dispatch time. If you can, the problem disappears.
2. Offer a short wait. If more stock is coming soon, tell the buyer the date and ask if they are happy to wait. Be honest; a date you miss is worse than no offer.
3. Offer a close alternative. A different colour, a newer version or a near match at the same price or lower. Only send it if the buyer agrees in the message thread.
4. Cancel and refund in full. If none of the above works, cancel through eBay with the honest reason. The buyer is refunded and the order is closed.

If the buyer replies that they would prefer to cancel, they can request a cancellation, or you can cancel with the buyer request reason because that is what actually happened. eBay's developer documentation and help pages describe the same line: a cancellation the buyer asks for does not add a defect, while an out of stock cancellation does.

Why you must not pick a false cancellation reason

It is tempting to choose buyer asked to cancel when the real reason is that you have no stock. Do not do it. eBay expects the reason to be true, and choosing a false one to avoid a defect breaks its rules. A misleading reason can draw much wider action against the account than a single defect ever would.

eBay also treats a full refund made outside its own system, such as sending money back through another route instead of cancelling, as an out of stock cancellation. There is no back door, and looking for one wastes the time you need to fix the cause.

The honest route is simple: tell the buyer the truth, let them choose, and record their choice in the eBay message thread.

A message you can adapt

Hello, thank you for your order. I am sorry: the item you bought is no longer in stock and I cannot send it within the time on the listing. I can offer you [the alternative] at the same price, or I can cancel the order and refund you in full today. Please let me know which you prefer, and I will act on it straight away.

Keep it short, apologise once, give clear choices and a time frame. Do not blame a supplier, and do not ask the buyer to cancel on your behalf.

What if the item is in stock but the cost has gone up?

A different problem looks similar. The item is still available, but your cost has risen since the buyer paid, and sending it now means a loss. Some sellers cancel these orders as out of stock. That is the wrong reason, because the stock exists, and it still produces a defect.

The buyer bought at the price you set. In most cases the right move is to send the item, take the loss on this order and fix the price on the listing so the next sale is profitable. If the loss is large, you can explain the situation to the buyer and ask whether they would like to cancel, but you must accept their answer. If they want the item, send it.

Example, with hypothetical numbers: you sold an item for £25 that cost you £18. Your cost is now £27. Sending it loses about £2 plus fees and postage on this one order. Cancelling as out of stock when it is not would put a defect on your record for months and break eBay's rules on cancellation reasons. The small loss is the cheaper outcome.

When your supplier cancels on you

If a supplier accepts your order and then cancels, treat it like an out of stock problem: look for another source first, then talk to the buyer. Record the supplier's cancellation so you can see whether one supplier causes most of your problems.

How much does an out of stock cancellation cost you?

Example, with hypothetical numbers. A seller has 300 transactions in the last 12 months, so eBay UK uses the 12 month window. eBay UK's Above Standard limit for the transaction defect rate is up to 2%, and Below Standard applies only when defects involve more than 4 different buyers, according to the seller performance policy.

• 2% of 300 transactions is 6 defects.
• The seller already has 4 defects from 4 buyers this year.
• Two more out of stock cancellations to two new buyers makes 6 defects from 6 buyers: exactly 2%.
• One more after that would go over the limit with more than 4 buyers involved, which would mean Below Standard at the next evaluation.

eBay says Below Standard can mean selling limits and higher final value fees. So a seller close to the line should treat every possible cancellation as expensive, and put the effort into finding stock or agreeing an alternative.

Why do eBay listings sell items that are not in stock?

Quantities set too high

A listing created with a large default quantity keeps selling long after the real stock is gone. Set quantities to what you have, or what your supplier can reliably send this week.

Stock shared across channels

If the same stock is sold on eBay and somewhere else, one sale elsewhere can leave the eBay listing overselling. Each sale needs to reduce stock in every place it is listed.

Supplier stock that moves faster than your listings

If you fulfil from a supplier, their stock changes without telling you. The longer between checks, the more likely an eBay order lands on an item they no longer have.

Sellers who fulfil through a third party should know eBay's drop shipping policy. Dropshipping, where you fulfil orders directly from a wholesale supplier, is allowed. Listing an item and then buying it from another retailer or marketplace that ships directly to your customer is not allowed. Whatever the source, the seller is responsible for delivering on time and for the buyer's satisfaction.

How do you stop it happening again?

• Switch on eBay's out of stock option in your account settings, so a listing at 0 quantity stays alive but hidden rather than ending. You can then set quantity to 0 whenever stock runs out.
• Keep quantities low on uncertain items. A quantity of 1 to 3 limits the damage if supply stops.
• Check supplier stock often. Match how often you check to how fast the item sells and how fast its stock moves.
• Keep a list of backup sources for your best sellers, so step 1 above has somewhere to look.
• Review every cancellation. Note the item and cause, and fix the listing before the next sale.

A stock guard that reads your source and sets the eBay quantity to 0 when the item is unavailable, then restores it when it is back, removes most of these sales before they happen. That is part of what Dropizon does for sellers who source from Amazon. It does not change eBay's sourcing rules or make cancellations disappear, so the habits above still matter.

A quick checklist for today

• Message the buyer within the hour, with clear choices.
• Look for stock or an alternative before offering a cancellation.
• Use the true cancellation reason, every time.
• Set the listing quantity to 0 until stock returns.
• Work out how many more defects your evaluation window can take.
