Sell product bundles, packs & custom quantities in WooCommerce with accurate inventory tracking. Set quantity multipliers per variation. $29/yr.

The Problem: WooCommerce Bundles Break Standard Inventory Tracking

When you sell products in sets, a 6-pack of eggs, a box of 12 wholesale items, or a bundle of 4 coffee mugs. WooCommerce deducts only 1 unit from stock per order by default, regardless of how many physical units the customer actually receives. This causes inventory errors, overselling, and stock count mismatches that are impossible to manage at scale.

The solution is to set a stock quantity multiplier per variation. When a customer buys the ‘6-pack’ variation, the plugin automatically deducts 6 units. When they buy the ’12-pack’, it deducts 12. Accurate bundle inventory tracking in WooCommerce, without any manual corrections.

How the WooCommerce Stock Quantity Multiplier Solves It

Per-Variation Quantity Control

Set a custom stock quantity multiplier for each product variation independently. Sell the same product as a single unit, a 6-pack, and a 12-pack, all from one product listing — with each variation deducting the correct number of stock units automatically.

  • Manage inventory based on product variations, not just overall product stock
  • Offer limitless quantity variations from a single WooCommerce product
  • Sell customised bundled products of the same type without creating separate listings

Accurate Bundle Inventory Deduction

Every time a customer purchases a bundle or pack variation, the WooCommerce inventory management plugin deducts the exact number of units the multiplier specifies. No manual corrections. No overselling. Your stock counts stay accurate in real time.

  • Automatically adjust stock up or down based on the variation’s multiplier value
  • Works with WooCommerce’s native stock management system
  • Eliminates inventory discrepancies caused by bundle and pack sales

Low Stock Notifications for Quantity Packs

Selling products in packs of 6 or 12 means your low stock threshold needs to account for the multiplier. The plugin ensures low stock notifications trigger correctly so you’re alerted before you run out of physical units, not just before you run out of listing slots.

  • Notify customers about low stock at the start of a product purchase
  • Keeps your store’s low stock warnings accurate for bundle and pack products

Who Is This Plugin Perfect For?

This plugin is perfect for:

  • Food & grocery stores: sell eggs in singles, 6-packs, or 12-packs with correct stock deduction
  • Wholesale & B2B stores: sell items in boxes of 6, 12, or 24 with accurate bulk inventory tracking
  • Apparel & fashion: sell socks, underwear, or accessories in size packs with per-variation stock control
  • Candles, cosmetics & lifestyle products: offer single units alongside gift sets and bundles
  • Any store selling the same product in multiple quantity options from one listing

Step 2

Set the Multiplier Value Per Variation

For each product variation, enter the stock quantity multiplier value that matches the number of physical units it represents. Set x1 for singles, x6 for a 6-pack, x12 for a box of 12 — the plugin handles the rest automatically.

Supports unlimited variations per product — ideal for food, wholesale, apparel, and any store selling the same product in multiple quantity sets.

Step 3

Customers See Accurate Stock on the Frontend

When a customer selects a variation and purchases, WooCommerce automatically deducts the correct number of stock units based on the multiplier. Stock levels on the frontend stay accurate in real time — no overselling, no manual corrections.

Low stock notifications also account for the multiplier — so you’re alerted at the right time, before you actually run out of physical units.

Accurately Manage Complex Product Quantity Options

Managing inventory is an important part of running an online store—it’s also one of the most challenging. Customers appreciate the option to buy 1, 2, 6, or 10 of an item. For instance, you may offer a set of 2, 4, or 6 coffee mugs. What if a client wants 3? Or a single mug as a replacement?  Selling product bundles and single quantities of the same item can cause inventory
errors when listed in a standard fashion. The solution is to offer additional quantity options through variations. The Custom Stock Quantity Multiplier for WooCommerce plugin gives you the option to offer quantity variations and accurately track your inventory.

Foire aux questions

How do I sell product bundles in WooCommerce with correct stock deduction?

Create a variable product with variations for each bundle size (e.g., Single, 6-Pack, 12-Pack). Use the WooCommerce Stock Quantity Multiplier plugin to set the multiplier for each variation. When a customer purchases the 6-Pack, WooCommerce automatically deducts 6 units from stock, accurate bundle inventory tracking without any manual work.

Does this plugin work with variable products and product variations?

Yes. The plugin is specifically designed for variable WooCommerce products. You set a quantity multiplier per variation, so each size or pack option deducts the correct number of stock units independently.

Will it affect my existing stock counts?

The plugin works with WooCommerce's native stock management system. It applies the multiplier at the point of purchase, so your existing stock counts remain as-is and deductions are handled correctly going forward once the multiplier is configured.

Can I sell items in sets of 6 or 12 in WooCommerce?

Yes. This is exactly the core use case. Set a variation for '6-Pack' with a multiplier of 6, and one for '12-Pack' with a multiplier of 12. Each purchase will deduct the correct number of units from your inventory automatically.

Does this work as a WooCommerce minimum order quantity plugin?

The plugin controls stock deduction per variation rather than enforcing minimum order quantities. For enforcing minimum or maximum order quantities, pair it with the WooCommerce Min/Max Quantities plugin.

What are the plugin requirements?

The plugin requires WordPress 4.9 or higher, WooCommerce 3.3 or higher, and PHP 5.6 or higher. It has been tested with WooCommerce 10.3.5 and is compatible with standard WooCommerce flows and extensions. Current version: 1.2.1.
