Description

WooCommerce plugin for configuring products which are sold by units but priced by weight.

Documentation | Contact

For example: fish, watermelon, cabbage.

How To define products which are sold by units but priced by weight

  1. In the plugin settings enable the ‘Quantity Units’ option
  2. Go to the edit product screen
  3. Set the price of 1 unit of the product in the price field (General tab)
  4. Set the weight of 1 unit of the product in the weight field (Shipping tab)
  5. Select ‘Weight’ in the ‘Quantity Units’ option (Unit Price tab)

How It Works

  1. The customer choose how many items he needs from the product
  2. On order creation the item quantity is recalculated based on its weight
  3. The shop owner will be able to update the quantity of it from the edit order screen after he weighs the item

For example:
1. The customer purchased 1 Salmon fish
2. The configured weight of Salmon fish is 3kg, when order is created the quantity of the fish will be modified automatically from 1 to 3
3. The shop owner will weight the actual fish, find out it’s 3.2kg, so he will change the quantity in the order from 3 to 3.2, the total price of the item will be updated automatically

Note: It’s recommended to use with Authorized / Delayed Payment method so the shop owner will be able to charge the exact amount after he weights the products, the order status should be ‘Pending payment’ / ‘delayed payment’.

How to config products which are sold by weight and not by units?

Use the ‘Quantity Step’ option, the ‘Quantity Units’ option should not be used.

How to sell the same product by both units and weight?

Create variable product and config each variation seperately.

Can you give an example of how to config products?

Salmon (sold by units but priced by weight): Price (General tab)- 45 (per unit), Weight (Shipping tab)- 3 (per unit), Quantity Units (Unit Price tab)- ‘weight’.

Tomatoes (sold by weight- kg): Price (General tab)- 2 (per kg), Quantity Step (Unit Price tab)- 0.1, Quantity Suffix (Unit Price tab)- kg.

Nuts (sold by weight- gram): Price (General tab)- 0.03 (per gram), Quantity Step (Unit Price tab)- 100, Quantity Suffix (Unit Price tab)- gram, Price Quantity (Unit Price tab)- 100, Price Suffix (Unit Price tab)- /100g.

How to manage the stock?

By the units that the product is configured (kg/gram).

Why sometimes there are many digits in the quantity field when using decimal Quantity Step?

Try using the WooCommerce built-in quantity buttons template or change to another quantity step.

How to fix the ‘The totals of the cart item amounts do not match order amounts’ error?

Tax: mostly the ‘Prices entered with tax’ and ‘Round tax at subtotal level’ options should be enabled.
Line Items: maybe prevent sending the line items to the payment gateway.
product price * product weight of products which are sold by units but priced by weight should not exceed 2 dp.
subtotal (include tax, exclude discount) of order line items should not exceed 2 dp (modify its quantities to fix it).
A tool which notify about exceeding prices is available.

Why I can’t edit the per product options?

The plugin is not compatible with the new product editor, and the new product block.

Excelente!

Works great

For my works perfect.

Good but needs a bulk editor

By mercystark on October 15, 2023

Plugin does the job however it needs a better documentation.
It would also would be great if we could just set Quantity Unit to "Weight" by Default instead of nothing or bulk edit all products or categories. For example set Quantity unit and suffix in bulk.

The best plugin of this kind that I met!

Solid for years now, they thought of everything.

Excellent plugin

By uebes on September 10, 2023

Perfect work.

We work as a “FoodCoop” in Austria and therefore we need a shop software which help us to sell foods. Some foods can be sell per unit (salad, milk bottle…) and for some foods (pumpkin, sausages…) we need the possibility to order per unit but to change the weight after delivery. Your plugin is the ideal extension to our woocommerce shop.

Thank you so much for your excellent plugin.

Best regards

Siegfried

Congratulations on such an excellent work. I have been using another decimal quantity plugin, but this one is very practical and its programming is excellent for loading speed.

The Best Plugin

This plugin is really amazing, a long time ago I thought about how to do to sell fractional products in bulk and I didn't know how to do it. searching I found this plugin, and after some tests, it worked perfectly. Congratulations on the excellent work and quality.
