Hello Petr,

Glad to assist,

(1) I believe the best way to get the B2C price here, would be to get it straight from the database, using get_post_meta functions.

In general, I think you can use this code to get the raw price values for the B2C regular and sale price:

global $post;
if (isset($post->ID)){
    $product_id = $post->ID;
    $b2c_regular_price = get_post_meta($product_id, '_regular_price', true);
    $b2c_sale_price = get_post_meta($product_id, '_sale_price', true);
}

It should work in archives as well. I think we can use one of the hooks from here https://www.businessbloomer.com/woocommerce-visual-hook-guide-archiveshopcat-page/ for the display.

For example, if we add this code snippet to functions.php:

add_action('woocommerce_after_shop_loop_item_title', function(){
    global $post;
    if (isset($post->ID)){
        $product_id = $post->ID;
        $b2c_regular_price = get_post_meta($product_id, '_regular_price', true);
        $b2c_sale_price = get_post_meta($product_id, '_sale_price', true);
        echo 'B2C Regular Price: '.wc_price($b2c_regular_price);
    }
}, 10, 1);

It results in:

(2) Is it possible to add product price for B2C with Vat and for B2B without VAT?

(A) I want to first mention that this is generally possible without custom code, by follow these steps:

-> Configure a tax exemption in B2BKing -> Dynamic Rules, for B2B users only.

-> Enable these settings in B2BKing - Settings -> Other: 

( the first setting is explained in more detail here: https://woocommerce-b2b-plugin.com/docs/how-to-display-rrp-recommended-retail-price-to-b2b-users/ )

The result would be the following, shown on both the archive and single product page:

(B) Or do you specifically only need to do it with code / in a custom plugin?

If so, generally you can get the B2B price ex VAT using:

if ($product->is_on_sale()){
    $product_price = $product->get_sale_price();
} else {
    $sale_price = $product->get_regular_price();
    $product_price = $sale_price;
}
$product_price = round(floatval(b2bking()->b2bking_wc_get_price_to_display( $product, array( 'price' => $product_price))),4);

And the B2C price can be obtained as described at (1).

It can depend on your WooCommerce -> Settings -> Tax page configuration.

Looking forward to your reply,

Kind regards,

Stefan

I want to assing porduct prices for B2C with VAT and B2B without VAT in backend, directly in to woocommerce. Is here any posiblity?

I understand you're referring to how prices are entered in the backend.

To set this up, please add the following PHP code snippet to your site:

add_filter('option_woocommerce_prices_include_tax', function($val){
    $user_id = get_current_user_id();
    $is_b2b = get_user_meta($user_id, 'b2bking_b2buser', true);
    if ($is_b2b === 'yes'){
        $val = 'no'; // prices entered ex tax for B2B
    } else {
        $val = 'yes';
    }
    return $val;
}, 10, 1)

Then you will enter prices differently for B2C and B2C:

For example in this image, 119 is VAT inclusive, and 90 is VAT exclusive.

Client has some B2C customers with additional discout 5% for all customs. Is there any way how to create B2C group for it? - I have solution in my head, but it's more dificult then B2C group.

I don't see a great solution I'm afraid. I think in that case they have to be set as B2B users in their own group.

The concept of the plugin is that if a user has special pricing / discounts, it cannot really be a B2C user.
