# Discount codes

**Discount codes** are available from the **Pro** plan. Creating one, and how it behaves on the machine, is in the [Discount code](/en/guides/navody/everyday-operation/slevovy-kod.md) guide.

The list shows the code text, the type (percent or amount), validity, how many times it was used, and whether it is active. A code from a voucher after a failed vend is marked in the list — it was created on its own; do not create one by hand as a replacement.

You cannot change the code after saving. You can change the discount, validity, and usage limit. The machine rejects a code that is turned off or revoked. A code applies to all machines on your account. A machine of another company does not know it.
