10 ratingsPolski 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.

External Services
The plugin makes no external calls except the ones listed below. Each one is off until you switch on the module and enter the account, ID or address it needs. The Compliance checklist fetches your own shop’s pages only.
GUS REGON API
When the VAT ID (NIP) lookup module is enabled, the plugin can connect to the public GUS REGON registry to fetch company data based on the VAT ID entered by the user. The connection is made only after the lookup is deliberately triggered.
- Data sent: the VAT ID (NIP).
- Service address: https://wyszukiwarkaregon.stat.gov.pl/
- Terms of service: https://api.stat.gov.pl/Home/RegulaminBIR
- Privacy policy: https://bip.stat.gov.pl/
VIES (European Commission)
When the EU VAT ID check module is enabled, the plugin can connect to the European Commission’s VIES service to confirm that a customer’s EU VAT number is registered. The connection is made only when the check is deliberately triggered from the order screen.
- Data sent: the customer’s EU VAT number and, if you configure one, your own VAT number, which is what makes it a qualified check and returns a consultation number.
- Service address: https://ec.europa.eu/taxation_customs/vies/
- Terms of use: https://ec.europa.eu/taxation_customs/vies/#/help
- Privacy policy: https://commission.europa.eu/privacy-policy-websites-managed-european-commission_en
Swiss UID register (Federal Statistical Office)
When the EU VAT ID check module is enabled and the number is Swiss (CHE), the same check from the order screen asks the Swiss UID register instead of VIES.
- Data sent: the customer’s Swiss UID or VAT number.
- Service address: https://www.uid-wse.admin.ch/
- Terms of use and data protection: https://www.uid.admin.ch/Disclaimer.aspx

- Data received: the Google account ID, e-mail address and name.
- Service address: https://accounts.google.com/

- Terms of service: https://policies.google.com/terms
- Privacy policy: https://policies.google.com/privacy
Tracking tags (advertising and analytics)
When the Tracking Tags module is enabled, each provider below loads only if you switch it on and enter your own ID, key or domain. Its script is placed in the page as an inert placeholder and runs in the visitor’s browser only after the visitor grants the matching consent category in the cookie banner (marketing for advertising pixels, analytics for measurement tools). Nothing is sent from your server.
- Data sent: the page address, referrer, browser and device data, the visitor’s IP address and the provider’s own cookie identifiers, plus a page-view event. The plugin sends no order or customer data through these tags.

Google Fonts preconnect
When the Safe Fonts module is enabled and Google Fonts are not held back until consent, the plugin adds preconnect hints for fonts.googleapis.com and fonts.gstatic.com, so the visitor’s browser opens a connection to Google before your theme loads its Google Fonts. Data sent: the visitor’s IP address and browser data. Terms, privacy policy, Google Fonts privacy FAQ.
Featured product video
When the Featured Video module is enabled and you enter a video address (for example YouTube or Vimeo), WordPress fetches the embed code from that provider through its oEmbed feature, and the visitor’s browser loads the player from the provider. Data sent: the video address from your server; the visitor’s IP address and browser data from the player. The provider’s own terms and privacy policy apply.
AI features (WordPress AI Client)
The optional AI features do not call a provider themselves: they hand a prompt to the WordPress AI Client, and the AI provider plugin you install and configure (for example OpenAI, Anthropic or Google) sends it to that provider. Nothing is sent when no provider is configured.
- Withdrawal reason classification (off by default, Withdrawal settings): after a declaration is filed, the customer’s free-text reason is sent to classify it into a fixed category.
- GPSR safety text draft and product summary (AI Bridge module, off by default): when an admin clicks generate, the product name, short description and description are sent.
- The terms and privacy policy of the provider you configured apply.
Webhooks you configure
The Store health monitor and the CRA incident log (security.txt module settings) can post to a webhook address you enter. Nothing is sent unless you fill in that address.
- Store health monitor: an alert text with the store status and the failed checks, sent as JSON to your webhook URL.
- CRA incident log: the incident record you dispatch (reference, type, severity, status, title, summary, affected component and versions, dates, reporter and notes), sent as JSON to your webhook URL.
- The receiving service is the one you choose; its terms and privacy policy apply.
Admin-panel feedback and deactivation-form information are stored locally in WordPress and are not sent to an external service.

Which WooCommerce shop is Polski for?

Does Polski support GPSR in WooCommerce?
Yes. Polski adds GPSR-related product fields, including manufacturer, importer and EU responsible person data, product identifiers, safety warnings and instructions. The data can be filled in the product editor and in bulk via CSV import or export.
Can I show the manufacturer, importer and responsible person on the product page?
Yes. The GPSR module can store and display the manufacturer, importer and EU responsible person data on the WooCommerce product page. Visibility depends on the module settings and the data filled in for the product.

Yes. The Omnibus module records price history and can display the lowest price from the last 30 days on discounted products. You can adjust the display settings in the module panel.

Does Polski support VAT ID (NIP) in WooCommerce?
Yes. Polski includes features and hooks related to the Polish VAT ID (NIP), including detection of orders that may require invoice or KSeF handling. Field availability and behaviour depend on the enabled modules.

Polski is not a complete system for sending invoices to KSeF, but it adds mechanisms ready for integrations: flagging orders by VAT ID, a KSeF status column and hooks for invoicing plugins and custom integrations.
Does Polski issue invoices in WooCommerce?
Yes. The Invoices module adds an Issue invoice button to the order screen and numbers VAT invoices per year (FV/1/2026). The customer opens the invoice from My Account and prints it from the browser. It does not send invoices to KSeF and does not replace an accounting system. Invoices as PDF files, UBL/PEPPOL XML and the JPK_FA report come with Polski PRO.

Does Polski support CSV import and export?
Yes. Polski extends the WooCommerce CSV import and export with selected product data, including GPSR fields and other product information.
Does Polski have shortcodes?
Yes. The plugin provides shortcodes for selected modules, including GPSR information, withdrawal forms, DSA reports, complaint templates and shop messages.
Does Polski guarantee legal compliance?
No. Polski provides technical modules for WooCommerce, but it is not legal advice and does not guarantee that your shop is compliant. Your shop configuration, terms and obligations always have to be verified for your specific business.
Is Polski ready for the Cyber Resilience Act?
Polski follows security practices relevant to CRA readiness: updates are delivered through the official WordPress.org channel, vulnerabilities can be reported under a coordinated disclosure policy, the code uses standard WordPress security mechanisms, and external services are described in this readme. This is not a declaration of legal compliance.
Where do I report bugs or feature requests?
For day-to-day support use the WordPress.org forum. Technical bugs and feature requests can also be reported in the GitHub repository.
Does the plugin have a simple feedback form?
Yes. The admin panel includes a simple feedback form that stores messages locally in WordPress. Do not enter passwords, license keys or customer personal data there.
What happens when the plugin is deactivated and uninstalled?
