How to Build On-Demand Grocery App Like Instacart

Remember when grocery shopping meant driving to the store, wandering aisles for an hour, waiting in checkout lines, and hauling bags to your car? That experience hasn't disappeared, but millions of customers now skip it entirely. They open an app, select products, and get groceries delivered within hours or less. 

Instacart is one of the most successful examples of such an app that ranks among the top five leaders in online grocery delivery. And we’re talking about the company which doesn’t own warehouses, doesn’t stock products, doesn’t employ delivery drivers — and is still expanding profit margins. 

How? By connecting existing pieces — stores with inventory, shoppers with cars, customers with needs — and capturing their part at each transaction. Specifically, more than 10 cents of every dollar as a revenue. In Q3 2025 alone, the company processed $9.17 billion in orders — so it’d be easy to calculate.

All this proves again that this model works. Not just for a specific service, but as a blueprint for building scalable on-demand grocery delivery businesses without massive infrastructure investment. 

This guide breaks down how to build an app like Instacart, covering the business model, baseline vs. advanced features, development process, costs, and challenges you'll actually face.

First of all, what does "booming" actually mean? Let’s look at the numbers.

We’ll start with the online grocery delivery market as a whole. In 2025, it was valued at $750 billion and projected to grow 3.24x over the next five years. Between 2026 and 2031, the market is expected to post an impressive CAGR of 21.68%. To put it into perspective, imagine your personal bank account growing exponentially by ⅕ every single year.

To date, the largest market share still belongs to omnichannel retailers that sell both online and offline: last year they accounted for 45.78% of total revenue. However, it’s already clear that the market split by platform type is changing. By 2031, pure-play e-grocery platforms are forecast to deliver the highest CAGR at 23.95%. 

A similar shift can be observed by delivery type. While scheduled services still dominate with 59.72% of the online grocery market, on-demand services offering instant delivery are showing robust growth of over 30% year over year in leading urban centers.

On-Demand Food Delivery Platforms - Market, Trends & Opportunities

This trend is driven primarily by city workers who value quick access to fresh food, forgotten items, and last-minute grocery needs, with delivery requests peaking in the evenings and on weekends. Looking more closely at the United States, the growing popularity of on-demand delivery is fueled by the fact that solo-resident households expand, encouraging smaller basket sizes but more frequent orders. 

Instacart is both a cause and a consequence of this shift in how consumers shop.

Speed became standard. Instacart reports that 75% of their delivery orders arrive within 90 minutes, with 25% of priority orders delivered in under 30 minutes. Customers now expect groceries faster than they can drive to the store themselves. 

Data drives personalization. With over 1.5 billion lifetime orders processed, platforms like Instacart use purchase patterns to recommend products, predict demand, and optimize delivery routes. This level of personalization increases order frequency and basket size. 

Advertising creates new revenue. Over 7,500 brands advertise on Instacart's platform, seeing an average 25% sales boost. This transforms grocery apps from pure transaction platforms into marketing channels where Consumer Package Goods (CPG) brands pay for visibility. 

The business model is proving profitable. Instacart's net income margin hit 15% of revenue in Q3 2025, while operating expenses dropped as a percentage of transaction volume. The model gets more efficient at scale — a rare quality in marketplace businesses.

An Instacart clone isn’t about copying its brand or design. You’re replicating the operational model. So what fundamentally sets it apart from other delivery services? 

01. Asset-light structure. Many other delivery services (like Amazon Fresh or Walmart Grocery) rely on their own inventory and warehouses, whereas Instacart doesn’t: it works through partner stores and acts as a marketplace with a full-service operational layer, or in simple terms, a digital middleman between the customer and the seller. 

This allows them to expand into new cities quickly by simply adding new store partners, without building their own physical infrastructure. What’s more, it lowers operational expenses: as of Q3 2025, the company spends a modest 4.8% of Gross Transaction Value (GTV) on running the entire business, and this figure slightly decreased since Q3 2024.

02. Gig economy. Instacart doesn’t hire and coordinate in-house delivery drivers or warehouse workers — they fully rely on freelance or contract shoppers. Anyone looking to earn extra income and meeting the platform’s requirements can sign in to accept and fulfill orders. This approach reduces fixed labor costs and also lets the service scale and cover new stores or regions without heavy investments in personnel.

03. Monetization. Unlike omnichannel retailers who primarily earn from direct product sales, Instacart rests on two key pillars:

• transaction revenue including commissions and fees ($670 million in Q3 2025 alone with 10% year-over-year growth);
• advertising and other revenue ($269 million during the same period with the same 10% increase YoY).

Because platforms like Instacart don't own physical stores, warehouses, or delivery fleets, they're entirely dependent on technology to function. Real-time inventory sync ensures customers see accurate stock levels, GPS tracking connects shoppers to stores and delivery addresses, payment infrastructure splits commissions, tips, and payouts automatically across multiple parties, and so on.

Let's break down what that actually looks like from the inside.

Building a grocery delivery platform like Instacart means orchestrating a four-sided ecosystem: 

• customers who want groceries;
• stores that stock them;
• shoppers or delivery drivers who fulfill orders;
• an operator that connects all sides and turns interactions into revenue.

So that all parties benefit (especially you, since you’re the one expecting it to make money), the app should work the way each side expects it to. That’s why feature selection should start with seeing the product through their eyes.

Moreover, not every grocery delivery app needs the same feature set. Think of functionality as a customizable sandwich at Subway: you pick the base (MVP must-haves), then layer on extras based on your market dynamics, competitive positioning, available budget, and so on.

How to Develop a Grocery Delivery App for Your Business

In this section, we’ll break down the Instacart clone from the perspective of each key player in the ecosystem and divide features into two groups: the building-blocks you need from day one, and advanced capabilities you can add later (or skip entirely, depending on your strategy). 

Your customer app is where most users form their first (and often final) impression of your service. If browsing feels slow, checkout breaks, or delivery doesn't match expectations — they're gone. 

Your MVP should focus on speed, clarity, and trust: let users find products, place orders, and track delivery without friction. Advanced features come later to increase repeat orders and lifetime value.

Shoppers are the operational backbone of your platform. They're contractors, not employees — which means they'll only stick around if your app helps them make money efficiently. If your app wastes their time with poor navigation, unclear payouts, or clunky interfaces, they'll switch to a competitor that respects their hustle. 

Your MVP must make accepting, shopping, and delivering orders as efficient as possible. Advanced features help them earn more, work smarter, and stay loyal to your platform.

Retail partners need visibility and control without operational chaos. They're juggling in-store customers, inventory, and staff — your platform should integrate seamlessly, not add workload. 

The MVP gives them order notifications, basic inventory sync, and payout tracking. Advanced features turn them into active growth partners by enabling promotions, analytics, and smoother operational integration.

The admin panel is your mission control. It's where you monitor platform health, resolve disputes, manage users across all sides, and make data-driven decisions. Without it, you're flying blind. 

Your MVP should cover essential operations: user management, order oversight, and basic reporting. Advanced tools unlock scalability: fraud detection, dynamic pricing, route optimization, and deep analytics that turn raw data into actionable insights.

Creating any grocery app includes five core stages that turn ideas into a live product customers actually use. 

Who are your target users — busy professionals, parents, elderly customers avoiding crowds? Which stores will partner with you first? What's the competitive landscape in your region, and where are the gaps? This phase includes analyzing competitors (Instacart, local players, niche delivery apps), conducting user interviews, and defining your unique value proposition. Skipping research is the fastest way to build something nobody needs.

Define your minimal viable product (MVP) scope: what features unlock revenue immediately versus what drives long-term retention. For an Instacart-like platform, you'll need customer ordering, shopper fulfillment tools, store partner integration, and an admin panel to monitor operations. Map user flows for each role, prioritize features, and decide which third-party integrations are non-negotiable for day one. Create wireframes and prototypes to visualize the customer journey and eliminate friction before development starts.

Your technology foundation determines development speed, scalability, and maintenance costs. The key decisions: cross-platform or native mobile development, backend architecture that handles high transaction volumes, database structure for users and orders, and which third-party services to integrate for payments, mapping, notifications, and delivery tracking. The right stack lets you launch faster and scale without rebuilding from scratch.

Let’s look at a concrete example. At dev.family, we build mobile apps with React Native because one codebase runs on both Android and iOS. This covers everything foodtech businesses need and cuts development costs because one developer handles both platforms simultaneously. For backends and web, we use React and PHP — the most widely adopted technologies in the industry. That means when your app is live and you need to hire someone for support and new features, you won’t struggle to find talent. No obscure frameworks, no vendor lock-in, just mainstream tech that's here to stay.

Development happens in sprints: build core features first (registration, catalog, cart, checkout, order tracking), then layer in advanced functionality (batch ordering for shoppers, loyalty programs, AI recommendations). Throughout this phase, QA runs in parallel — testing across devices, operating systems, and real-world scenarios like order placement, GPS accuracy, payment flows, edge cases (refunds, out-of-stock substitutions, failed deliveries). Bugs in critical flows — payments, routing, inventory sync — destroy trust instantly, so thorough testing isn't optional.

Submit your apps to app stores, set up analytics and monitoring, onboard your first stores and shoppers, and prepare customer support channels. But launch is just the beginning. Successful platforms iterate continuously based on user feedback, fix bugs, optimize performance, and add features as they scale. Treat launch as the start of ongoing improvement, not the end of development.

Okay, we've covered the steps. But how much time do they actually take, and what kind of investment are we talking about?

Let’s start with cost. And to be clear: there’s no quick or easy answers here. Development costs typically start around $25,000 for a very lean MVP and can scale in++----------------------------------------------------------------------------to six figures for a production-ready, multi-sided marketplace with advanced functionality. The investment grows with ambition: the more complex your ecosystem and the richer your feature set, the higher the budget required.

The price varies widely depending on platform complexity (how many sides your marketplace connects), feature scope (MVP basics versus advanced AI and automation), number of integrations (payments, mapping, courier services, POS systems), design requirements (template-based or custom branded), and team expertise and location.

So what about timelines? The same factors that influence cost also shape development speed. To illustrate how timelines vary even for similar business models, let's look at two marketplace projects we built.

Belbazar is a fashion marketplace connecting local clothing brands with customers. When they approached us, they already had a stable website with existing backend infrastructure and an in-house developer maintaining the API. Their goal was straightforward: create a mobile app to expand their sales channel and improve shopping convenience. 

We built a customer-facing mobile app for iOS and Android, integrated it with their existing API without touching the backend, and implemented classic e-commerce features: product catalog with filters, favorites, cart, checkout, order tracking, and customer support chat. The architecture was clean and lightweight, optimized for speed and reliability. 

Why it was fast? 

The project scope was clearly defined from the start. We weren't building a marketplace from scratch — we were translating an existing, proven website experience into a mobile format. The backend was ready, the business logic was stable, and the client knew exactly what they needed. No complex integrations, no multi-sided workflows, no experimental features. Just solid execution.

What they got?

37,500+ installs, positive user feedback on usability and performance, and seamless integration with existing operations.

Godno is a marketplace for small businesses, artisans, and handmade sellers — a local alternative to platforms like Etsy. Unlike Belbazar, this project started from zero: no existing infrastructure, no backend, no defined workflows. The client came to us with an idea and a vision for "a beautiful, aesthetic marketplace" but wasn't sure how it should actually work. 

We built the website and mobile apps from scratch, creating a two-sided marketplace with distinct experiences for buyers and sellers. Sellers got onboarding with verification checks, store management tools, inventory sync, custom product options, and delivery settings. Buyers got a visual product catalog, video support, order tracking, and checkout. 

We also implemented payment infrastructure with automated commission splits and secure transaction holds, built a real-time chat system for negotiations, created moderation and arbitration tools for dispute resolution, and integrated delivery cost calculation with local courier services. 

Why it took longer?

This wasn't just app development — it was building an entire business ecosystem from the ground up. We worked as a technical partner, not just a dev team: researching the market, prototyping workflows, consulting on business logic, iterating on features based on early user feedback. The scope expanded during development as we identified competitive advantages and added functionality competitors didn't offer. 

What they got?

Live and actively scaling marketplace with 3,200+ products, 290+ sellers, and a growing community. 

Both projects are marketplaces that, in general terms, do the same — both connect buyers and sellers. But now you see it clear that the timeline can vary depending on what you’ve already done and what you’re going to do. 

The Instacart model works. It's proven profitable, scalable, and doesn't require owning warehouses, stocking inventory, or hiring delivery fleets. Instead, it relies on technology to orchestrate a multi-sided ecosystem where stores, shoppers, and customers all benefit and you capture value at every transaction.

The entry barrier isn't as high as it seems. You don't need Instacart's $9 billion in quarterly volume to make the economics work. You need a clear target market, a focused MVP, and disciplined execution. 

The businesses that win in grocery delivery won't be the ones with the biggest marketing budgets. They'll be the ones that control their tech stack, iterate based on real user data, and build experiences tailored to their specific market — not a catch-all aggregator template. And we can help you get there.
