Changing what Shopify reads as "Quantity" for a product order

Hi all!

I need Shopify to put out squaremeters as my orderquantity. Instead of "5 boxes" i need it to put out "25m²". We have coded an individual calculator that lets customers put in their desired squaremeters of flooring and then shows the next best number of prepackaged boxes they would need. I can't use unit prices because we had to use individual metafields. We use an Ecommerce Management System (JTL) that prevents us from using unit prices. Is there a way i can make shopify treat product quanitities like this?



this number needs to be the order quantitythis number needs to be the order quantityMetafieldsMetafields

Hi Robin, 

this is not possible as for shopify the quantity is something like 1 Product. So you cant buy just a fraction of a product which is the reason for shopify to work only with int numbers. You could reach your goal by describing the quantity in a different way. So for example a quantity of 1 could be 0.1qm.

Hello, thanks for your reply,

Yes, i am trying to describe a quantity of 1 as 3,955qm, which is why i set up these metafields. How would i go about doing this the right way?

I had a similar situation with a flooring provider and their solution was to have the quantity calculated based on the customers required `width` and `length` and then to round it up.

So if a customer needed 3m x 4.5m it would figure out how much they needed based on how much a pack of the flooring would contain, round that value up and set that as the quantity.

In that example there's 2.39m2 in a pack.

3 x 4.5 = 13.5

13.5 / 2.39 = 5.6

Quantity = 6

This doesn't work for everyone but they were happy with that approach and it's been quite successful for them.

I had a similar problem with my products, as I wanted to sell 0.5m pieces I solved it like this: https://www.stoffdorado.de/collections/stoffe-farbe-uni/products/jersey-uni-schwarz

If you want to add a description somewhere near the quantity selector, you can add the text in your product template in between the following block:

{% if section.settings.show_quantity_selector %}
...
...
add and style your description here
{% endif %}

Your solution only shows how to display it in the front end, but it doesnt show up as 50cm in the order, it still uses integer numbers right?

i thought this would work with the unit prices. If i can tell shopify how much quantity there is for a specific price, it should also be able to deduct how much of that quantity the customer has ordered. So my unit price is 3.955m² for 158€. If the customer pays 474€, it should be easy to tell shopify that the order quantity is 11,865m².

There is no 100% clean solution for this issue, because the backend only accepts integers. There's only a dirty solution by calculating with int in the backend and showing a decimal at the frontend. This will work for the cart, but at some point you will have to explain your customer why he sees a quantity of for example 120, although he wanted to order 1.2.

I just learned that this can be done with line item properties to customize a product. I need to test if my management system can read that as order quantity now.

The line item properties is just an array, so i cannot imagine, how this should solve the problem. Good luck though
