# Cash register - basic terms and prerequisites

The cash register in the partner Zoyya web application is used to open and close a cash register, issue receipts, and review issued receipts and cash-register records. It is available on both desktop and mobile.

## Where is the cash register?

* **Desktop:** **Receipts > Cash register**
* **Mobile:** open **Cash register** on the bottom navigation bar

On desktop and mobile, you can use **Active cash register**, **Issued receipts**, **Cash register overview**, **Payment devices**, and **Operators**.

## Key concepts

**Cash register** is the work journal for a specific payment device. Receipts are issued while the cash register is active.

**Active cash register** is open and has not yet been closed. A cash register for the current date must be open before a new receipt can be issued.

**Closed cash register** can no longer be used to issue new receipts, but it remains available in the cash-register overview.

**Payment device** stores the business-premises label, device label, fiscalization certificate, payment methods, and other details required for issuing receipts.

**Operator** is the person issuing a receipt. At least one active operator is required.

**Receipt** is the issued document containing items, amounts, payment method, operator, and fiscalization data when applicable.

**Receipt cancellation** does not delete the original receipt. The original receives the **Cancelled** status, and Zoyya creates a new cancellation receipt with negative quantities and amounts.

## Requirements for issuing receipts

Before issuing the first receipt, verify that the location has:

* a plan and user permissions that allow access to the cash register
* registered business premises and correct business-premises and payment-device labels
* a payment device with a valid fiscalization certificate when fiscalization is required
* at least one active operator
* the required payment methods
* an open cash register for the current date

If a requirement is missing, Zoyya displays **Cash register settings need to be updated!** and indicates what needs attention.

|| Important: You cannot issue a new receipt without an active cash register opened for the current date.
