Vendor Card

The extension on the vendor card provides two main features: entering and validating the OIB number, and automatically fetching company data from the Croatian Court Register.

Note

VAT ID validation via the EU VIES system is only available on the Customer Card, not on the Vendor Card.

OIB Field

A new identifier has been added to the vendor card:

Field	Description	Note
OIB	Croatian personal/company identification number (11 digits)	Automatically validated when entered

Where is it?

The OIB field is located on the vendor card, in the general information section.

How to enter an OIB?

1. Open a vendor card (Vendors > select a vendor).
2. Enter the 11-digit OIB in the OIB field.
3. Press Tab or leave the field — the system automatically checks whether the OIB is valid.

Invalid OIB

If you enter an OIB that fails the checksum validation, the system will display:

"OIB (XXXXXXXXXXX) is not valid. Please enter a valid OIB."

Check the number and try again.

Where to find an OIB?

A company's OIB can be found in the Croatian Court Register at sudreg.pravosudje.hr or on official company documents (contracts, invoices, registration certificates).

Court Register Synchronization

The Sud-Reg Sinkronizacija button automatically fills in company details by fetching data from the Croatian Court Register (Sudski registar).

What gets filled in automatically?

Field	Source
Name	Short company name from the Court Register
Address	Registered office street and house number
City	Registered office city/settlement
Post Code	Looked up automatically based on address
E-Mail	First email address from the register (if available)
VAT Registration No.	OIB prefixed with HR (e.g. HR12345678901)
Country/Region Code	Always set to CROATIA

How to use it?

1. On the vendor card, enter the OIB (the field must be filled in).
2. In the ribbon, click the Sud-Reg Sinkronizacija button (in the Process group).
3. The system fetches data from the Court Register and automatically fills in the fields.
4. When complete, the message "Company data successfully fetched and updated." is shown.

Before synchronizing

The OIB field must be filled in and valid. If it is empty, the system displays:

"Please enter OIB before fetching company data."

Which name is imported?

The system imports the short company name (skraćena tvrtka). If no short name is available in the register, the full name is used instead.

Post Code

The post code is looked up automatically based on the address. If it cannot be found (e.g. for unusual addresses), the field will remain empty — enter it manually.

What to do after synchronization?

Review the filled-in fields and correct or supplement as needed (e.g. phone number, contact person). All imported data can be edited manually.
