Implementing bulk dynamic pricing in WooCommerce can significantly enhance the shopping experience by encouraging larger purchases through volume discounts. While many choose plugins for this functionality, a custom-built solution without plugins offers flexibility and greater control. This guide explains how to implement WooCommerce: Bulk Dynamic Pricing (Without Plugins), including how to add custom fields for dynamic settings and display these on product pages.
Adding Custom Fields for Bulk Pricing
First, we’ll add custom fields in the WooCommerce product dashboard where store managers can define bulk pricing rules.

function wcsuccess_add_bulk_pricing_fields() {
woocommerce_wp_text_input( array(
'id' => 'bulk_pricing',
'label' => 'Bulk Pricing (Qty:Discount)',
'placeholder' => 'e.g. 100:5,500:10',
'desc_tip' => 'true',
'description' => 'Enter pairs of quantities and discounts separated by colons and commas.',
'type' => 'text',
));
}
add_action('woocommerce_product_options_general_product_data', 'wcsuccess_add_bulk_pricing_fields');
function wcsuccess_save_bulk_pricing_fields($post_id) {
$woocommerce_bulk_pricing = $_POST['bulk_pricing'];
if (!empty($woocommerce_bulk_pricing))
update_post_meta($post_id, 'bulk_pricing', esc_attr($woocommerce_bulk_pricing));
}
add_action('woocommerce_process_product_meta', 'wcsuccess_save_bulk_pricing_fields');Modifying Cart Pricing Based on Custom Fields
Next, we adjust the cart pricing dynamically based on the defined bulk pricing rules.

add_action('woocommerce_before_calculate_totals', 'wcsuccess_quantity_based_pricing', 9999);
function wcsuccess_quantity_based_pricing($cart) {
if (is_admin() && !defined('DOING_AJAX')) return;
if (did_action('woocommerce_before_calculate_totals') >= 2) return;
foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
$bulk_pricing = get_post_meta($cart_item['product_id'], 'bulk_pricing', true);
if (!$bulk_pricing) continue;
$pricing_rules = explode(',', $bulk_pricing);
foreach ($pricing_rules as $rule) {
list($threshold, $discount) = explode(':', $rule);
if ($cart_item['quantity'] >= $threshold) {
$price = round($cart_item['data']->get_price() * (1 - ($discount / 100)), 2);
$cart_item['data']->set_price($price);
}
}
}
}Displaying Bulk Pricing on Product Pages
To help customers understand the available bulk discounts, we’ll display them on the product page in a clear table format.

function wcsuccess_display_bulk_pricing_table() {
global $product;
$bulk_pricing = get_post_meta($product->get_id(), 'bulk_pricing', true);
if (!$bulk_pricing) return;
$pricing_rules = explode(',', $bulk_pricing);
echo '<table class="bulk-pricing"><thead><tr><th>Quantity</th><th>Discount (%)</th></tr></thead><tbody>';
foreach ($pricing_rules as $rule) {
list($threshold, $discount) = explode(':', $rule);
echo '<tr><td>' . esc_html($threshold) . '+</td><td>' . esc_html($discount) . '%</td></tr>';
}
echo '</tbody></table>';
}
add_action('woocommerce_single_product_summary', 'wcsuccess_display_bulk_pricing_table', 20);Conclusion
Implementing WooCommerce: Bulk Dynamic Pricing (Without Plugins) not only provides a customizable approach to pricing but also enhances transparency, allowing customers to understand how much they can save by purchasing in bulk.
