Filters & hooks

Every configurable value is also a filter, so a theme or companion plugin can override it without touching the stored option.

Configuration

Filter	Overrides
wc_pricebook_tiers	Tier definitions
wc_pricebook_rules	Rule → taxonomy bindings
wc_pricebook_visibility_roles	Visibility role definitions

Identity & membership

Filter	Overrides
wc_pricebook_pricing_user	Resolve the effective (parent) pricing user — see Multi-account
wc_pricebook_is_manager	Whether a user is a pricing manager
wc_pricebook_user_tier	Whether a user belongs to a given tier
wc_pricebook_category_roles	A user's category → role mappings

Meta keys

Point the plugin at a store's existing meta instead of its defaults:

Filter	Overrides
wc_pricebook_user_meta_keys	Per-user meta keys (My Products, include/exclude categories, category roles)
wc_pricebook_user_pricing_meta	Per-customer product-price override meta key
wc_pricebook_base_meta	MSRP / base price meta key
wc_pricebook_bulk_pricing_meta	Quantity-break meta key

Pricing

Filter	Overrides
wc_pricebook_tier_requires_explicit_sale_price	Require a tier's own sale price to be "on sale" (default: fall back to the MSRP sale price when lower)
wc_pricebook_allow_zero_price	Keep a resolved $0 as a real price. Default false blanks it to "Call for Price" — see Price resolution

Pricelist export

Used by the pricelist export:

Filter	Overrides
wc_pricebook_export_settings	Recipient / schedule / role filter
wc_pricebook_export_product_ids	The product refs included in the export
wc_pricebook_export_user_query	The WP_User_Query args used to gather users
wc_pricebook_export_batch_rows	Target CSV rows per background (Action Scheduler) batch — default 5,000

Example

// Treat a custom capability as the "distributor" tier.
add_filter( 'wc_pricebook_user_tier', function ( $has, $user_id, $tier_key ) {
    if ( 'distributor' === $tier_key ) {
        return user_can( $user_id, 'b2b_customer' );
    }
    return $has;
}, 10, 3 );
