Hello Gökhan,

Those rules are in conflict with each other - they cannot really work together that way I'm afraid.

I believe we can help achieve the desired setup with a code snippet.

To make sure I understand correctly:

• Is the idea that you want the group B2B MWST FREI to see prices ex tax on shop pages, but see the price with tax in cart. And then check their VAT nr on the checkout page to possibly remove VAT completely?

You mentioned:

but I want the VAT number to be checked again at the time of order.

• Normally B2BKing will check the VAT number only once (once it's added, it's saved as valid to the user profile). Are you saying you want to re-check it again whenever an order is placed? B2BKing doesn't have a feature for it, but we could add a code snippet to remove it and force the customer to add it / validate it again when placing each order. Would that work for you?

Kind regards,

Stefan

Hi again,

I believe you can achieve it as follows:

1. Remove B2B Mwst Frei from this rule: https://prnt.sc/QpVoszm2Y0-a

2. Add this PHP snippet to your site:

add_filter( 'option_woocommerce_tax_display_cart', 'mwst_frei_price_ex_tax', 10000 );
add_filter( 'option_woocommerce_tax_display_shop', 'mwst_frei_price_ex_tax', 10000 );

function mwst_frei_price_ex_tax($val){
	
	$user_id = get_current_user_id();
	$user_id = b2bking()->get_top_parent_account($user_id);

	$currentusergroupidnr = b2bking()->get_user_group($user_id);
	$group_name = get_the_title($currentusergroupidnr);

	if ($group_name === 'B2B (Mwst Frei)'){
		return 'excl';
	}

	return $val;
}

I believe it should allow the other rule to work without conflicts.

This code can be added to functions.php, or to any code snippets plugin.

If this does not work for you, could you clarify what exactly happens for the group Mwst frei vs what should happen. Or share a site access so we can check it directly?

Kind regards,

Stefan
