Касса для Атол is an Android application that primarily caters to entrepreneurs who require mobility and have a small inventory. The app allows you to print receipts on Atol fiscal registers via USB, Wi-Fi, or Bluetooth. It does not require any registration.

The program's settings enable you to specify the default name that will print in the receipt lines, such as "Delivery Service," without selecting from the directory. Each position's quantity and price must be specified to generate each item.

The app allows you to issue a sales receipt with two types of payment (cash and electronic). Cash sales are possible with change calculation and change output on the receipt. The app also supports return receipts for purchases.

Additional features include cash deposits, shift reports without clearing, cash withdrawals, item directory with name search, and distinction between goods and services.

Please note that before issuing a return receipt, ensure that there is sufficient cash in the register (generate an uncleared report). If there is insufficient cash, make a cash deposit. The Atol fiscal register monitors cash availability and will not allow returns, regardless of the type of payment for the return receipt.
