Price products by the amount customers need

Flexible Quantity Calculator for WooCommerce PRO lets a store configure products for sale by entry, weight, length, area, volume, or another defined unit. The store sets the unit and pricing rules. Customers pick a quantity and, when enabled, enter product dimensions. The calculator uses those settings to calculate the price and can display it upfront on the product page when it depends on customer-entered dimensions.

This setup suits goods sold by measured length, surface area, weight, or volume, where an item count alone does not describe the amount being ordered.

Choose units and configure dimensions

Measurement examples include grams, kilograms and pounds; millimetres, centimetres and metres; square metres and square feet; millilitres, litres and gallons; and cubic units. PRO also lets you create custom units, such as a box, bundle, or pallet.

Enable unit dimensions and give each field a name and label that fits the product. Set a dimension to a fixed value or allow the customer to enter it. You can choose its unit of measure, set minimum and maximum values and increments, and add or conceal dimensions as needed.

Set pricing, quantity, and inventory rules

Configure prices using dimensions and unit measurements, and use a pricing table for ranges. Quantity settings include minimum and maximum values, increments, and decimal values. Inventory can be calculated using the new unit of measure. These rules can also be used with the standard item unit.

Set shipping and product variations

When shipping requirements depend on the amount ordered, assign a shipping class based on product quantity and configure flexible shipping costs with quantity-based pricing. Product variations are supported for catalogs with related options that need various configurations.

Connect product fields and invoices

The plugin works with custom fields from Flexible Product Fields. It is also compatible with Flexible PDF Invoices for WooCommerce & WordPress, which can show new units of measure on WooCommerce PDF invoices. PRO includes priority email support.

Configure a product

1. Edit the WooCommerce product and enable the calculator settings.
2. Choose the unit, set its price, and define quantity limits and increments.
3. Enable any required dimensions, then set their labels, units, fixed values or customer input, ranges, and increments.
4. Configure pricing and shipping rules, then review the product page to confirm the customer fields and calculated price match the way the product is sold.
