Does the plugin generate a credit note?

No. The plugin creates a refund in WooCommerce (with exact line items and amounts) and a PDF withdrawal declaration as a legal document. A credit note is a separate accounting document typically generated by an invoicing plugin (e.g. WooCommerce PDF Invoices, Flexible Invoices, WP-Hermes). We work correctly with these plugins – the WooCommerce refund triggers the issuance of a credit note in their workflow.
