Polski for WooCommerce

Polski for WooCommerce is a free WooCommerce plugin for Polish online shops. It issues numbered VAT invoices, and helps you organise GPSR product data, the Omnibus lowest-price history, GDPR consents, the right of withdrawal, VAT ID (NIP) handling, unit prices, hooks for KSeF processes, DSA reports and storefront modules.

The plugin is modular. You can enable only the features a given shop needs, for example GPSR, Omnibus, cart consents, withdrawals, unit prices, food data, a wishlist, a product comparison or AJAX search.

Polski helps you configure the technical shop processes related to the Polish and EU market. It is not legal advice and does not guarantee regulatory compliance. Your shop configuration, terms, products and obligations always have to be verified for your specific business.

Key modules

• Omnibus price history – records and displays the lowest price from the last 30 days on discounted products.

• GDPR consents and checkboxes – configurable consents at checkout, registration and reviews, with a consent log.

• VAT margin scheme – the art. 120 annotation on invoices for second-hand goods, works of art, collectors’ items and antiques.

The storefront disclosure of AI-generated product copy is a Polski PRO feature, since it labels copy from the Pro AI description generator.
