Custom Multi-Location Fulfilment Solution (Shopify)

We are seeking an experienced Shopify developer to build a custom solution to improve how we manage multi-location inventory for pop-up stores.

The Problem

Our client operates pop-up retail stores globally

Staff use Shopify POS to place orders when an item is not available in-store

Shopify shows total stock availability, but does not clearly show which location the stock is held in at the point of sale

As a result:

Orders are placed without control over fulfilment location

Shopify automatically assigns or splits orders across multiple locations

This creates operational inefficiencies and poor customer experience

What We Need

We require a custom-built solution (private app or backend extension) that:

Displays live inventory by location at the point of order creation

Allows staff to select the fulfilment location BEFORE the order is placed

Prevents Shopify from auto-assigning or splitting orders incorrectly

Works within or alongside Shopify POS workflows

Does not rely on draft orders as a workaround

Key Requirements

Clean, simple interface for retail staff

Real-time stock visibility across all locations

Seamless integration with existing Shopify setup

Reliable and scalable solution suitable for global use

What We’re Looking For

Proven experience with Shopify (apps, APIs, POS extensions)

Strong understanding of multi-location inventory logic

Ability to propose the best technical approach (custom app, middleware, etc.)

Please Include in Your Response

Relevant Shopify experience / examples

We are open to recommendations on the best way to achieve this and are looking to move quickly with the right developer.
