Weight Products for WooCommerce

Sell products by weight in WooCommerce and adjust the final price after weighing. Built as an add-on for Order Picking App, but also works standalone.

Sell products where the final weight is determined after picking

Weight Products for WooCommerce is designed for webshops that sell products where the exact weight is only known after picking or weighing.

Customers place orders using an estimated quantity (e.g. 1 kg of tomatoes), while the actual weight is determined later during fulfillment. The order can then be updated with the real quantity, and WooCommerce automatically recalculates the price.

Ideal for:
– Fresh produce (fruit & vegetables / AGF)
– Meat, fish and poultry
– Cheese and delicatessen
– Nuts and bulk goods
– Farm shops and local delivery services

Designed for Order Picking App

This plugin is built as an add-on for Order Picking App, enabling a seamless workflow between:

1. Order placement in WooCommerce
2. Picking and weighing via Order Picking App
3. Updating actual weights
4. Automatic recalculation of order totals

Pickers or backoffice staff can enter the actual measured weight, ensuring accurate pricing.

Works standalone with WooCommerce

This plugin also works fully standalone.

You can:
– Mark products as weight-based
– Allow decimal quantities (e.g. 1.25 kg)
– Adjust quantities in the WooCommerce order admin
– Automatically recalculate totals after updates

Key Features

• Weight-based products in WooCommerce
• Custom unit support (kg, g, lb, liter, piece, etc.)
• Default quantity per product
• Decimal quantity support
• Store ordered and actual quantities
• Edit actual weight in order admin
• Automatic recalculation of totals
• Quantity display with units in cart and orders
• Fully compatible with WooCommerce HPOS

How it works

1. Customer places an order

– Product price is set per unit (e.g. €3.49 per kg)
– Customer orders a quantity (e.g. 1.25 kg)

1. Picking and weighing

– Actual weight is measured (e.g. 1.18 kg)

1. Order update

– Enter actual quantity in admin
– Line item quantity is updated
– WooCommerce recalculates totals

Use Case: Grocery & Fresh Products

WooCommerce is built around fixed quantities, but real-world fresh products vary in weight.

This plugin allows:
– Estimated ordering
– Real-world weighing
– Accurate final pricing

Perfect for stores selling price-per-kg products with post-order adjustments.
