About this plugin
This plugin adds an admin order metabox where you can enter IČO or DIČ and fetch company details from the RÚZ (Register účtovných závierok) public API.
It fills billing company name, street, city, postcode, and country, and it can also fill custom order meta fields for IČO, DIČ, and IČ DPH based on your setup (for example WPify Woo or Superfaktura). You can configure the meta field keys in the plugin settings.
For customers
An optional “Load from IČO” widget can be enabled on the WooCommerce checkout page. Customers enter their IČO (8-digit company ID) and click the load button — the billing company name, address, city, postcode, and country are filled in automatically. Works with both the classic WooCommerce checkout and the Gutenberg blocks-based checkout.
Enable this feature in WooCommerce → IČO priradenie settings.
