Hi Anabell,

Thank you for getting in touch,

The plugin can be fully translated to Spanish, by using any translation plugin, such as the free Loco Translate plugin. We have a guide here for translating the plugin using Loco: https://woocommerce-b2b-plugin.com/docs/how-to-translate-b2bking-to-any-language-localization/ 

This applies to all elements in the frontend, backend, as well as all emails the plugin generates. 

Let me know if I can help with anything, or if you have any questions,

Kind regards,

Stefan
