Hi Jose,

Thank you for getting in touch,

The plugin doesn't have a feature for this, but it's easy to set up by adding a code snippet to the site.

For example, the following snippet will hide stock for all B2C & Logged out users:

$is_b2b_user = get_user_meta(get_current_user_id(),'b2bking_b2buser', true);
if ($is_b2b_user !== 'yes'){
    add_filter( 'woocommerce_stock_html', function($html, $text, $product){
        return '';
    }, 10, 3 );    
}

You can also show stock only to specific groups by slightly modifying the above snippet.

Kind regards,

Stefan
