Hi Francisco,

The plugin does not have a Spanish translation already included,

However, the plugin is fully translateable to any language, for example using the free Loco Translate plugin.

We have a guide here for how you can translate the plugin to a different language with Loco: https://woocommerce-b2b-plugin.com/docs/how-to-translate-b2bking-to-any-language-localization/

Kind regards,

Stefan
