What is Payme Business?

Payme Business is a payment platform for businesses in Uzbekistan. It allows merchants to accept payments from Uzcard and HUMO bank cards online via the Payme mobile app, Telegram bots, email, or SMS. Funds are deposited to the business's bank account through Payme Business kassas (cash registers).

There are 3 types of kassa:

1. Kassa with billing — requires integration setup (Merchant API or Subscribe API)
2. Kassa without billing — requires integration setup
3. Kassa for on-site payments — works immediately after connection

Only legal entities can use kassas: IP, ChP, OOO, AO, GUP, SP, NOU.
