Sell software license keys online, delivered the moment buyers pay
Sell software license keys on Kamai: separate inventory per edition, bulk import with duplicate checks, and instant delivery after payment.
Software license keys, activation codes and serial numbers are the classic “code” product: each one is a unique string the buyer enters into the software to activate it. Orders tend to be small and arrive at all hours, so delivering keys by hand means night-time and holiday orders wait for hours. Kamai hands delivery to the system — once payment succeeds, the key appears on the delivery page.
Three things that go wrong when selling license keys
1. Mixed editions. One product often comes in personal and professional editions, or one-year and lifetime licenses. If their keys share an inventory, a buyer of the personal edition can receive a professional key. On Kamai every product has its own code inventory, so create one product per edition and the problem cannot happen.
2. Selling a key twice. If a bulk import accidentally includes keys that were already sold, the same key goes to two buyers. Kamai skips any code that duplicates an existing one during import and tells you how many were actually added.
3. Failed activations with no follow-up. Keys can fail because of region locks or prior use. Buyers can file an “invalid code” complaint with their order number, and the store verifies and sends a replacement — with a record on both sides.
A recommended setup
| Step | Recommendation |
|---|---|
| Create products | One product per edition or license term, with both in the title |
| Write the description | Supported OS, number of devices, supported regions and activation steps |
| Import keys | One per line, pasted or uploaded as TXT, up to 1,000 per import |
| Set price and fee | Choose per product whether you or the buyer pays the transaction fee |
| Share your store | Send your store link to buyers or add it to your site and community |

License keys are information-dense and buyers usually know exactly what they want, so the compact-list store layout works well, with price and stock visible at a glance. See product cards or compact list?
The buyer’s experience
- no account needed, checkout on a single page;
- pay with USDT, Alipay or WeChat Pay;
- the key is shown right after payment with a copy button;
- optional email copy, and lookup by order number later.
Getting paid
The platform collects payments and merchants withdraw to USDT, a bank card or Alipay, manually or with hourly automatic withdrawals, from a ¥10 minimum. See automatic delivery and payments and payouts.
Only sell keys you are authorized to resell. Selling pirated, cracked or untraceable keys violates the terms of service.
