# Grocery delivery app development > A grocery delivery app suite includes a customer app for ordering, a store or dark-store app for picking and packing, a rider app for delivery and an admin panel for catalogue, slots, pricing and reports. Infikey builds grocery and quick-commerce apps with live inventory and route optimisation. A full suite typically costs USD 30,000–70,000. Customer, picker, rider and admin apps for scheduled or instant grocery delivery, with live stock, substitutions, delivery slots and real-time tracking. - **Budget:** USD 30k–70k (INR 25–55 lakh) - **Apps:** Customer, picker, rider, admin - **Models:** Scheduled slots, 10–30 minute delivery ## Apps and features | App | Key features | |---|---| | Customer app | Location-based catalogue, search, offers, slots or instant delivery, substitutions preferences, wallet, live tracking, reorder | | Picker app | Pick lists by aisle, barcode scanning, weight-based items, substitution approvals with the customer | | Rider app | Order assignment, navigation, batch deliveries, proof of delivery, COD collection | | Admin | Catalogue and pricing per store, slot capacity, delivery zones, promotions, rider management, reports | | Store POS sync | Stock and price sync from POS or ERP so the app never sells what is out of stock | ## Scheduled or quick commerce? - **Scheduled delivery** (same day or next day slots) works from existing stores and suits larger baskets and lower costs. - **Quick commerce** (10–30 minutes) needs dark stores close to customers, tight assortment, fast picking and dense rider networks. Software must be very fast at stock accuracy and dispatch. - **Hybrid** models offer instant delivery for a small range and slots for the full range. We design zones, slot capacity and dispatch rules around the model you choose. ## Cost | Scope | Budget (USD) | Budget (INR) | |---|---|---| | Single-store ordering app with delivery management | 12,000–25,000 | 10–20 lakh | | Full suite: customer, picker, rider and admin apps | 30,000–70,000 | 25–55 lakh | | Multi-city quick commerce with dark-store operations | 70,000–150,000 | 55 lakh–1.25 crore | Compare with apps you know using the [app like cost calculator](https://infikeytechnologies.com/tools/app-like-cost-calculator). ## Compliance notes Food businesses need the relevant food safety licence (FSSAI in India, municipality permits in the UAE, local authority registration in the UK, state and local permits in the US). Apps should show required product information such as ingredients, allergens, expiry and MRP or unit pricing, and handle age-restricted items with verification at delivery. ## Project blueprint: Quick delivery app for a neighbourhood supermarket chain Based on the requirements we hear most often from buyers like this. A supermarket chain with stores across one city sees customers move to quick-commerce apps. It wants its own app for fast delivery from each store, using store stock and its own riders. What we would build: - Customer app with store-based catalogue, live stock and slot or express delivery - Picker app for in-store picking with substitutions and barcode checks - Rider app with batching, navigation and proof of delivery - Store dashboard for orders, stock-outs and rider status - Loyalty and offers tied to the chain’s existing programme How success is measured: - Orders per store per day - Order accuracy and substitution rate - Average delivery time and delivery cost per order - Repeat customers in their first months ## Frequently asked questions ### How much does a grocery delivery app cost? A full grocery delivery suite with customer, picker, rider and admin apps typically costs USD 30,000–70,000 (about INR 25–55 lakh). A single-store ordering app costs USD 12,000–25,000. ### Can the app sync with our store POS? Yes. We integrate with your POS or ERP to sync stock and prices, and push online orders back for billing, so online and in-store inventory stay accurate. ### How are substitutions handled? Customers set preferences per item. When an item is out of stock, the picker app suggests alternatives and the customer can approve in the app or by WhatsApp before the order is packed. ## Related guides - [E-commerce development company](https://infikeytechnologies.com/industries/ecommerce): Infikey Technologies builds e-commerce and retail software: D2C websites on Shopify, WooCommerce or custom stacks, multi-vendor marketplaces... - [Courier and delivery app development](https://infikeytechnologies.com/industries/logistics/courier-delivery-app): A courier delivery app suite lets customers or merchants book deliveries, assigns orders to riders, optimises routes, shares live tracking a... - [Flutter vs React Native: which should you choose?](https://infikeytechnologies.com/compare/flutter-vs-react-native): Choose Flutter when you want pixel-consistent custom UI, smooth animations and one team owning iOS, Android and possibly desktop.
