Weight Based Inventory

Retired Boards Appdev Fulfillment Api

Topic summary

Main issue: Shopify restricts inventory quantities to whole numbers, limiting weight‑based or fractional sales. The request is to support decimal inventory (e.g., up to two decimal places).

Workarounds via third‑party apps exist but don’t fit all cases. External POS integrations often can’t or won’t integrate with those apps, and custom builds are costly and uncertain.

Technical point: The ask is for native, platform‑level decimal inventory—rather than app‑layer solutions. The poster argues this should be straightforward to implement.

A participant suggested using weight units (kilograms vs grams) to represent fractions (e.g., 2.45 kg as 2450 g), then acknowledged they misunderstood; the topic is inventory quantities, not product weight.

No decisions or official Shopify response. The discussion remains open with a clear feature request.

Key terms: POS = point of sale; inventory = stock quantities; decimals = fractional units.

Hi all,

I find it extremely limiting and frustrating that Shopify only allows inventory in whole numbers. There are plenty of use cases online for a need to allow up to 2 decimal places.

I know there are apps that somewhat have a workaround for this but it doesn’t work for all scenarios. For example, I have a POS system from another provider that has a Shopify integration, for it to work they would also need to integrate with an app on Shopify, which is not a viable option as not all app developers have the capability or willingness to integrate or it’s too expensive to get the POS company to build a custom integration for an app that may or may not be around for the future.

Technically speaking this shouldn’t be that much of an issue with Shopify to manage inventory up to 2 decimal places for example 2.4. The maths isn’t super complex! :slightly_smiling_face:

This feature needs to come from Shopify rather than an app. Just wanted to vent my frustrations!

Hi , there

Already supporting both kilograms (kg) and grams (g), so if your product is 2.45 kg for example, you have the flexibility to set it as 2450 g. This feature can be quite useful.
