The act of selling goods on Taobao is an offer (with complete commodity information, price, quantity, etc. ), and the buyer's bid is a promise. In civil law, the artistic conception of your sales contract takes effect. If the seller fails to deliver the goods or is out of stock, the seller will constitute a breach of contract, so the seller will bear the liability for breach of contract. Taobao's regulation is to regulate the delay in delivery time and the liability for breach of contract, which does not belong to strong buying and selling.

So if it is out of stock, I suggest you withdraw the goods, or make a reservation, estimate when the goods will be delivered, and communicate with the buyer to avoid disputes.

Answer your supplementary question. It means that the inventory you filled in when you put it on the shelf does not match the actual inventory, which is also your problem. False inventory is also a kind of deception, because whether the buyer likes it or not, you take up the buyer's time and money.

In a word, sellers can't argue on this issue, especially in e-commerce. Once the buyer has photographed and paid, you must deliver the goods. If the stock is not enough, it will be removed from the shelf. This is your job, there is no excuse.
