Dark stores need retail operating systems
Former head of strategy at a global on-demand giant on the economics of grocery delivery
This points to how early these dark store businesses still were, they had physical warehouses and couriers before they had purpose built commerce software. In practice, a Shopify like stack means stitching together a basic storefront, checkout, order management, and local delivery tooling so a customer can tap through a basket and a rider can get dispatched, without yet having the custom software needed to optimize picking, substitutions, inventory, and promotions at the warehouse level.

That made sense at the time because demand was tiny. The interview describes UK dark stores doing only 30 to 50 orders a day in many cases, so speed to launch mattered more than building deep internal systems.

A Shopify like setup is good for taking orders, not for squeezing warehouse economics. The real margin levers in quick grocery are higher basket size, lower spoilage, tighter picking, and better item availability, all of which require software tied directly to inventory and fulfillment operations.

The long term comparison is less an online store and more a retail operating system. That is where companies like Instacart and Rohlik have been heading, by selling merchant software or turning internal fulfillment tools into standalone products.
The next phase is a shift from hacked together storefronts to software that runs the whole dark store, from what gets stocked, to what gets picked, to how routes are batched. The operators that survive are the ones that turn delivery speed into repeatable warehouse efficiency, not just a nice looking app.
