# Obtaining a certificate for fiscalization

A fiscalization certificate is required when Zoyya issues and fiscalizes receipts. It is issued by Fina; once issued, you download a **.p12** file and keep the password created during download. You can prepare and configure the certificate whether you use the partner Zoyya web application on desktop or mobile.

## If you already have a certificate

Prepare:

* the active **.p12** fiscalization certificate file
* the password for that **.p12** file
* the organization tax ID that matches the certificate tax ID

| Tip: Save the password as soon as you download the certificate. The **.p12** file cannot be unlocked in Zoyya without it.

## If you do not yet have a certificate

1. Open the official [Fina fiscalization certificate page](https://www.fina.hr/poslovni-digitalni-certifikati/poslovni-certifikati-za-fiskalizaciju/izdavanje-certifikata-za-fiskalizaciju).
2. Choose whether to submit the documents digitally through OSPD or in person at a Fina office.
3. Prepare the application, agreement, proof of payment, and any documents required for your case.
4. After processing, download the activation details and **.p12** certificate.
5. Create and save the certificate password.

For a first certificate, Fina may require additional documents to register the business entity in its PKI system. Follow Fina's current official instructions.

## Configuring the certificate in Zoyya

The certificate is uploaded to a payment device:

* **Desktop:** **Receipts > Cash register > Cash register settings > Payment devices > select the payment device**
* **Mobile:** **Cash register > Cash register settings > Payment devices > select the payment device**

If you are creating a new device, follow:

* [Creating a new payment device (desktop)](https://help.zoyya.com/en/article/creating-a-new-payment-device-desktop-qdjshp/)
* [Creating a new payment device (mobile)](https://help.zoyya.com/en/article/how-to-create-a-payment-device-mobile-128emsz/)

If you are replacing the certificate on an existing device, follow [Changing the payment device and its effect on invoice numbers (desktop)](https://help.zoyya.com/en/article/changing-the-payment-device-and-its-effect-on-invoice-numbers-desktop-scn2qc/) or open the same payment-device details on mobile.

Have the **.p12** file and its password ready when contacting Zoyya support for help.

## If the certificate cannot be loaded

* **Incorrect certificate password** means the entered password cannot unlock the selected **.p12** file.
* **Certificate verification failed** means the selected file or password did not pass certificate validation.
* If the certificate has expired, is not a production certificate, or its tax ID does not match the organization tax ID, prepare the correct certificate before retrying fiscalization.

|| Important: A certificate and business-premises registration are separate requirements. Both are needed for fiscalization through Zoyya; register the premises using [Registering business premises for a cash register](https://help.zoyya.com/en/article/registering-business-premises-for-a-cash-register-mgn4ml/).
