# Cash register setup

Cash register setup includes preparing the fiscalization certificate, registering the business premises, and configuring organization details, payment devices, operators, and payment methods. You can set up and use the cash register in the partner Zoyya web application on both desktop and mobile.

## Where is the cash register?

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

## Recommended setup order

1. Prepare the fiscalization certificate using [Obtaining a certificate for fiscalization](https://help.zoyya.com/en/article/obtaining-a-certificate-for-fiscalization-1aav5h0/). The certificate must belong to the tax ID of the business entity that will issue the receipts. Send the certificate in **.p12** format and its password to **info@zoyya.com**. Include the business entity's name and tax ID and the registered business-premises label.
2. Before issuing fiscalized receipts, register or verify the business premises in ePorezna using [Registering business premises for a cash register](https://help.zoyya.com/en/article/registering-business-premises-for-a-cash-register-mgn4ml/). If you are unsure whether to use an existing business premises or register a new one, confirm this with your accountant.
3. Verify the details shown on receipts:

   * [Organization data (mobile)](https://help.zoyya.com/en/article/organization-data-mobile-13oyxi1/)
4. Create a payment device. Enter the business-premises label from ePorezna in the payment-device settings in Zoyya, then enter the device label:

   * [Creating a new payment device (mobile)](https://help.zoyya.com/en/article/how-to-create-a-payment-device-mobile-128emsz/)
5. Add the people who issue receipts using [Adding and editing operators](https://help.zoyya.com/en/article/adding-and-editing-operators-18zvuv/).
6. Select the default payment device:
   * [Setting the default payment device (desktop)](https://help.zoyya.com/en/article/setting-the-default-payment-device-desktop-hdrn3/)
   * [Setting the default payment device (mobile)](https://help.zoyya.com/en/article/how-to-set-the-default-payment-device-mobile-psmsul/)
7. Verify the available payment methods:
   * [Payment methods on a payment device (desktop)](https://help.zoyya.com/en/article/payment-methods-on-a-payment-device-desktop-1mbhmru/)
   * [Payment methods on a payment device (mobile)](https://help.zoyya.com/en/article/payment-methods-on-a-payment-device-mobile-kxjclq/)
8. If you print receipts directly from a computer, configure the printer using [Setting up an invoice printer (desktop)](https://help.zoyya.com/en/article/setting-up-an-invoice-printer-desktop-umy57z/).
9. Open the cash register:
   * [Opening the cash register (desktop)](https://help.zoyya.com/en/article/opening-the-cash-register-desktop-119u7yl/)
   * [Opening the cash register (mobile)](https://help.zoyya.com/en/article/how-to-open-a-cash-register-mobile-1qzeb6t/)

|| Important: The business-premises label registered in ePorezna must match the label entered on the payment device in Zoyya. The payment device must have a valid certificate, a default operator, and the required payment methods enabled.

## If a receipt was issued but not fiscalized

1. Open the issued-receipts overview:
   * **Desktop:** **Receipts > Cash register > Issued receipts**
   * **Mobile:** **Cash register > Issued receipts**
2. Open the receipt with the fiscalization warning.
3. Once the internet connection is stable again, select **Fiscalize**.
4. Verify that the receipt shows **JIR** and **ZKI**.
5. If fiscalization still cannot be completed, send Zoyya support the receipt number and a screenshot of the error message.

|| Important: Do not issue a second receipt only because fiscalization failed. Fiscalize the existing receipt later using **Fiscalize**.
