Description
The WooCommerce Quantity Manager configures minimum, maximum, and multiple increment quantity rules for WooCommerce products, applicable per individual product, variation, category, tag, or user role. Merchants working with wholesale, kits, or fixed bundles use the plugin to force orders in multiples of 6, require a minimum of 12 units for resale items, or set a default pre-filled quantity on the store’s add-to-cart button.
Key Features
- Rules by scope: applies global limits, per category, per tag, per specific product, or directly on variations.
- Minimum, maximum, and multiples: sets a starting value, unit cap, and mandatory increments (e.g., 2, 4, 6, 8) at purchase.
- Default quantity: pre-fills the quantity field on the product and in the cart with the store-suggested value.
- Rules by user role: differentiates limits between regular customers, wholesalers, and other roles registered in WordPress.
- Customizable messages: displays custom notices when the buyer tries to leave the configured rules for the item.
Benefits of WooCommerce Quantity Manager
- Wholesale sales: ensures feasible minimum orders for the B2B model without manual calculations at checkout.
- Fewer operational errors: avoids orders with quantities incompatible with fixed bundles or shipping multiples.
- Stock control: blocks purchases above the defined limit for low-availability or promoted items.
- Centralized setup: brings all rules together in a single WooCommerce screen, with no code required.
Who Is It For?
- Wholesale WooCommerce stores and distributors that require a minimum volume per order.
- Businesses selling products in bundles, boxes, or kits with fixed units.
- Hybrid B2C/B2B operations that need different rules by customer type.
Aimed at WooCommerce store managers who need to standardize purchase quantities and separate policies between retail and wholesale within the same catalog.
