CX Tiered Pricing for WooCommerce

Simple tiered pricing management for WooCommerce products and variations.

Overview

CX Tiered Pricing allows store administrators to define quantity-based pricing tiers for WooCommerce products and product variations.

The plugin integrates with the CX Pricing Engine and automatically applies the correct unit price based on the selected quantity.

Features

• Quantity-based pricing tiers
• Support for simple products
• Support for product variations
• Admin interface for managing tiers by SKU
• Automatic WooCommerce price synchronization
• Integration with CX Pricing Engine
• Product and variation cleanup on deletion
• Lightweight database structure
• No frontend templates required

How It Works

Example:

If a customer orders:

• 5 units → €10.00 each
• 10 units → €9.50 each
• 30 units → €8.75 each
• 100 units → €7.99 each

The highest matching tier is used.

Requirements

• WordPress 6.0+
• WooCommerce 7.0+
• PHP 8.0+

Optional:

• CX Pricing Engine

Installation

1. Upload the plugin folder to:

   wp-content/plugins/cx-tiered-pricing

2. Activate the plugin from WordPress Admin.

3. Navigate to:

   Products → Tiered Pricing

4. Enter a product SKU and load its pricing tiers.

Managing Tiers

Simple Products

Search by SKU and define quantity / price pairs.

Example:

Variable Products

When a parent variable product SKU is loaded, all variations are displayed.

Each variation can have its own pricing structure.

Variation SKU

You may also search directly using a variation SKU.

Only that variation will be shown.

Database

The plugin creates a single custom table:

wp_cx_tier_prices

Structure:

Unique key:

(product_id, variation_id, qty)

Price Resolution Logic

The plugin finds the highest tier that does not exceed the requested quantity.

Example:

Configured tiers:

Customer quantity:

30

Selected tier:

25 → 8.75

WooCommerce Price Synchronization

Whenever tiers are saved:

• The lowest tier price becomes the WooCommerce product price.
• Variation prices are updated automatically.
• Variable product pricing is re-synced.

This ensures:

• Correct price display
• Correct catalog sorting
• Correct WooCommerce price indexing

CX Pricing Engine Integration

If the CX Pricing Engine plugin is available, a pricing rule named:

tier

is automatically registered.

The pricing engine can then request tier prices through:

CX_Tiered_Pricing_Prices::get_tier_price(
    $product_id,
    $variation_id,
    $qty
);

Public Methods

Get tier price

CX_Tiered_Pricing_Prices::get_tier_price(
    $product_id,
    $variation_id,
    $qty
);

Get all tiers

CX_Tiered_Pricing_Prices::get_all_tiers(
    $product_id,
    $variation_id
);

Get available quantities

CX_Tiered_Pricing_Prices::get_qty_tiers(
    $product_id,
    $variation_id
);

Get lowest tier quantity

CX_Tiered_Pricing_Prices::get_lowest_tier_qty(
    $product_id,
    $variation_id
);

Replace all tiers

CX_Tiered_Pricing_Prices::replace_tiers(
    $product_id,
    $variation_id,
    $tiers
);

Notes

• Tier prices are stored independently from WooCommerce pricing tables.
• Product deletion automatically removes related tier pricing records.
• Variation deletion removes only variation-specific tiers.
• The plugin is intentionally lightweight and follows standard WordPress development practices.
