We build grocery delivery apps for supermarkets, local grocers, and multi-store marketplaces — a customer app, a picker/store app, and a driver app, plus the catalogue and inventory backend that grocery actually demands. Grocery is harder than it looks: thousands of SKUs, weight-based items, out-of-stock substitutions, and time-slot delivery all have to work smoothly. We build for those realities so your app handles a full weekly shop, not just a handful of products.
Why Grocery Apps Are Harder Than They Look
A food delivery order is a few items; a grocery order can be sixty. That changes everything: you need fast catalogue search across thousands of SKUs, weight-and-quantity handling for loose produce, real-time stock so customers do not order what is out, and a substitution flow for when an item runs out mid-pick. On top of that, grocery runs on scheduled delivery slots rather than instant dispatch. We build these grocery-specific mechanics from the start, because retrofitting them into a generic delivery app is where most grocery projects stall.
Store Operations and Picking
The customer app is only half the system. The picker or store app is what makes grocery delivery actually work at scale — staff receive orders batched by delivery slot, pick items with barcode scanning, handle substitutions with customer approval, and hand off to drivers. We build this operational layer alongside the customer experience, plus an admin panel for catalogue management, pricing, promotions, and delivery-slot capacity, so your team can run real fulfilment rather than fighting the software.

Frequently Asked Questions
How much does a grocery delivery app cost?
A grocery delivery app with customer, picker, and driver apps plus catalogue management typically ranges from $35,000-$85,000+ depending on catalogue size, number of stores, and fulfilment complexity.
Can you build an app like Instacart or BigBasket?
Yes — those are multi-store grocery marketplaces with customer, shopper, and driver apps. We build that model, or a single-supermarket app, depending on your business.
How do out-of-stock substitutions work?
When a picker finds an item unavailable, the app offers a substitution the customer can approve or decline in real time, keeping orders accurate and customers in control.
Does it support scheduled delivery slots?
Yes — customers book time slots with capacity limits, so your team can plan picking and delivery instead of being overwhelmed by instant orders.
How long does it take to build?
A grocery delivery app typically takes 4-6 months given the catalogue, inventory, picking, and delivery-slot complexity involved.
