ONDC App Development: Features, Cost & Development Process

Introduction

India’s digital commerce ecosystem is moving beyond traditional marketplace models. Instead of businesses depending entirely on one large platform to reach customers, open digital networks are creating new ways for buyers, sellers, logistics providers, and technology companies to connect.

One of the most important initiatives in this space is ONDC (Open Network for Digital Commerce).

For businesses and technology companies, ONDC creates opportunities to build buyer applications, seller applications, commerce platforms, integrations, and specialized digital solutions that can participate in an open commerce ecosystem.

If you are planning to build an ONDC-compatible application or integrate an existing business platform with ONDC, this guide explains the major features, development process, technology requirements, estimated cost, and business models.

What Is ONDC?

ONDC stands for Open Network for Digital Commerce.

It is an open network designed to make digital commerce more interoperable. Rather than operating as a single marketplace, ONDC connects different participants through standardized network protocols.

In a traditional marketplace model, customers, sellers, payments, logistics, and other services may operate within one platform.

With an open network approach, different participants can provide different parts of the commerce experience.

For example:

Customer → Buyer App → ONDC Network → Seller → Logistics → Customer

This creates opportunities for businesses to develop specialized applications while participating in a wider digital commerce ecosystem.

ONDC has expanded beyond basic retail use cases and can support areas such as retail, food, mobility, logistics, travel, and other digital commerce services.

Why Build an ONDC App?

The biggest reason businesses consider ONDC development is flexibility.

A business can build its own digital experience instead of depending entirely on a single closed marketplace ecosystem.

An ONDC-based solution can be useful for:

• Retail businesses
• Grocery businesses
• Restaurants
• D2C brands
• Seller networks
• Local merchants
• Logistics companies
• Mobility businesses
• Travel businesses
• Large enterprises
• Digital commerce startups

For technology companies, ONDC also creates opportunities to develop specialized platforms for buyers, sellers, logistics providers, and other network participants.

Types of ONDC Applications You Can Build

ONDC is not limited to one type of application. The right solution depends on the business model and the role the company wants to play in the network.

1. ONDC Buyer App

A buyer application allows customers to discover products or services, compare available options, place orders, make payments, and track deliveries.

Typical features include:

• User registration
• Product discovery
• Search and filters
• Categories
• Product details
• Cart
• Checkout
• Multiple payment options
• Order tracking
• Reviews and ratings
• Notifications
• Customer support

2. ONDC Seller App

A seller application helps merchants manage their products and orders while participating in the digital commerce network.

Important features can include:

• Seller registration
• Business profile
• Product catalog
• Inventory management
• Pricing
• Order management
• Order status updates
• Offers and discounts
• Payment tracking
• Sales reports
• Customer management
• Notifications

For businesses managing multiple stores, the application can also include multi-location inventory and centralized administration.

3. ONDC Integration Platform

Existing e-commerce or business software does not necessarily need to be rebuilt from scratch.

Businesses can develop an integration layer that connects their existing systems with the ONDC ecosystem.

This may include:

• Catalog synchronization
• Order synchronization
• Inventory synchronization
• Payment integration
• Logistics integration
• Customer data workflows
• Status updates

• Retail
• Fashion
• Healthcare products
• Local services
• Travel
• Mobility
• Logistics

The application architecture can then be designed around the specific requirements of that industry.

Key Features of ONDC App Development

A successful ONDC application needs more than a basic shopping interface. The system needs to handle users, products, orders, payments, APIs, network communication, and business operations.

User Registration and Authentication

Users should be able to create accounts using options such as:

• Mobile number
• Email
• OTP
• Social login
• Password-based authentication

Businesses can also implement additional authentication methods for sensitive operations.

Product and Service Discovery

Search is one of the most important parts of a commerce application.

The application can provide:

• Keyword search
• Categories
• Filters
• Location-based discovery
• Price filters
• Availability
• Sorting
• Recommendations

For larger platforms, AI-powered search can make product discovery more relevant.

Product Catalog Management

Seller-side systems should allow businesses to manage:

• Product names
• Images
• Descriptions
• Pricing
• Stock
• Variants
• Categories
• Taxes
• Offers
• Availability

Catalog synchronization becomes particularly important when sellers are already using external inventory or ERP systems.

Cart and Checkout

The buyer application should provide a smooth checkout experience.

Core functionality includes:

• Add to cart
• Update quantity
• Address management
• Delivery options
• Order summary
• Coupons
• Taxes
• Payment selection
• Final confirmation

Digital Payments

ONDC applications can integrate appropriate payment services based on the business model.

Payment functionality may include:

• UPI
• Cards
• Net banking
• Digital wallets
• Payment gateways
• Refunds
• Payment status
• Transaction history

Security and reconciliation should be considered during development rather than added later.

Order Management

Both buyers and sellers need clear order workflows.

The system can support:

Order Placed → Confirmed → Packed → Dispatched → Out for Delivery → Delivered

Depending on the business model, cancellation, return, refund, replacement, and failed delivery workflows can also be included.

Real-Time Order Tracking

For delivery-based businesses, customers expect visibility after placing an order.

GPS and logistics APIs can be used to provide:

• Driver location
• Estimated delivery time
• Delivery status
• Route information
• Delivery notifications

Seller Dashboard

A seller dashboard can provide a central place to manage daily operations.

It can show:

• Orders
• Revenue
• Inventory
• Products
• Customers
• Payments
• Returns
• Delivery status
• Sales analytics

Admin Panel

The admin panel controls the wider platform.

Depending on the application, administrators may manage:

• Users
• Sellers
• Products
• Orders
• Payments
• Disputes
• Promotions
• Categories
• Reports
• Integrations
• Permissions

A role-based access control system can prevent unauthorized users from accessing sensitive information.

Advanced Features for an ONDC Application

Once the basic platform is ready, advanced functionality can improve efficiency and user experience.

AI-Powered Recommendations

AI can analyze customer behavior and suggest relevant products or services.

Intelligent Search

Natural-language search can allow users to search in a more conversational way instead of relying only on exact product names.

Demand Forecasting

Businesses can use historical sales data to estimate future demand and plan inventory.

Dynamic Business Analytics

Dashboards can track:

• Sales
• Orders
• Conversion
• Product performance
• Customer activity
• Seller performance

Automated Notifications

Push notifications, SMS, email, or WhatsApp-based communication can be integrated depending on the workflow.

Multi-Vendor Management

A marketplace-style platform can support multiple sellers, stores, brands, or service providers.

Multi-Location Management

Businesses operating across multiple cities can manage stores, inventory, orders, and employees from a centralized system.

ONDC API and Integration Development

API development is one of the most important technical parts of an ONDC solution.

An application may need to communicate with different systems for:

• Catalog
• Orders
• Payments
• Logistics
• Inventory
• Customer notifications
• Business management
• Analytics

The development team needs to understand the required network specifications and design the application architecture accordingly.

Existing systems such as ERP, CRM, POS, warehouse software, payment systems, and logistics platforms can also be connected through APIs.

This means a company does not always need to replace its existing software.

Instead, an integration layer can connect its current infrastructure with the required ONDC workflows.

Technology Stack for ONDC App Development

The technology stack depends on the application’s complexity and business requirements.

Mobile App

• Flutter
• React Native

The final technology stack should be selected according to scalability, security, integrations, development speed, and long-term maintenance.

How to Build an ONDC App?

Developing an ONDC application should start with the business model rather than coding.

Step 1: Define the Business Model

First determine whether you are building:

• Buyer application
• Seller application
• Logistics solution
• Integration platform
• Marketplace solution
• Industry-specific commerce platform

This decision affects the complete architecture.

Step 2: Identify ONDC Requirements

The development team should understand the relevant network specifications, workflows, APIs, and participant requirements for the selected use case.

Step 3: Plan the Application Architecture

The architecture should define:

• Frontend
• Backend
• Database
• APIs
• Authentication
• Payment system
• Admin panel
• Third-party integrations
• Cloud infrastructure

Step 4: Design UI/UX

The user experience should be simple, particularly for commerce workflows such as product discovery, checkout, order tracking, and seller management.

Step 5: Develop the MVP

The first version should focus on essential functionality instead of trying to build every possible feature.

For example, an initial buyer application may include:

• Registration
• Search
• Product discovery
• Cart
• Checkout
• Payment
• Orders
• Tracking

Step 6: Build Integrations

The required APIs, payment systems, logistics services, ERP, inventory systems, and other business tools can then be integrated.

Step 7: Testing

Testing should cover:

• API communication
• Payments
• Orders
• Catalog
• Inventory
• Security
• Performance
• Mobile responsiveness
• Error handling

Step 8: Deployment

After testing, the platform can be deployed on cloud infrastructure and prepared for production use.

Step 9: Monitoring and Optimization

After launch, performance, errors, transactions, API responses, and user behavior should be monitored.

Continuous optimization becomes important as transaction volume grows.

How Much Does It Cost to Build an ONDC App?

The cost depends heavily on the type of application, number of integrations, UI/UX complexity, backend architecture, security requirements, and advanced features.

A general estimate is:

ONDC Solution	Estimated Cost
Basic MVP	$20,000 – $40,000
Medium Application	$40,000 – $80,000
Advanced Platform	$80,000 – $150,000+
Enterprise ONDC Platform	$150,000 – $300,000+

These are development estimates rather than fixed quotes.

For example, a simple seller application with limited functionality will have a very different budget from an enterprise commerce platform integrating ERP, inventory, logistics, payments, analytics, AI, and multiple business locations.

Factors That Affect ONDC App Development Cost

The major cost factors include:

• Number of applications
• Buyer/seller/admin modules
• UI/UX complexity
• API integrations
• Payment integration
• Logistics integration
• ERP/CRM integration
• AI features
• Real-time tracking
• Security requirements
• Cloud infrastructure
• Testing
• Maintenance
• Development team location

Building both buyer and seller applications will naturally require more development effort than building a single application.

How Long Does It Take to Build an ONDC App?

The development timeline can vary depending on scope.

Typical estimates are:

• Basic MVP: 3–5 months
• Medium application: 5–8 months
• Advanced platform: 8–12+ months
• Enterprise solution: 12+ months

Integration-heavy projects can take longer because the timeline depends not only on development but also on testing and coordination across connected systems.

ONDC App Monetization Models

Businesses can use different monetization strategies depending on their role in the ecosystem.

Transaction Commission

Charge a percentage or fixed fee on completed transactions.

Subscription

Offer sellers or businesses monthly or annual plans.

SaaS Model

Provide commerce software as a recurring service.

Premium Features

Charge for advanced analytics, automation, AI, marketing tools, or enterprise functionality.

Logistics Revenue

A logistics-focused platform can earn revenue from delivery services.

ONDC App vs Traditional Marketplace App

These two approaches are not exactly the same.

Traditional Marketplace	ONDC-Based Approach
Usually controlled by one platform	Designed around an open network
Participants operate within the platform	Different network participants can connect
Platform owns the primary marketplace experience	Buyer/seller roles can be distributed
Integration depends on platform architecture	Uses defined network protocols
Business model depends on marketplace structure	Multiple participant and service models are possible

The right choice depends on the company’s business model, target users, technology requirements, and desired ecosystem.

Security Considerations

Commerce applications handle sensitive business and customer information, so security should be built into the architecture.

Important areas include:

• Secure authentication
• OTP protection
• Encryption
• API security
• Role-based access
• Secure payment processing
• Data protection
• Audit logs
• Fraud monitoring
• Secure cloud infrastructure
• Regular security testing

For enterprise applications, security requirements can become significantly more complex.

Why Businesses Should Focus on Scalability?

An application may start with a few thousand transactions but eventually need to support a much larger customer and seller base.

The architecture should therefore be designed for:

• Horizontal scaling
• Database optimization
• API performance
• Caching
• Load balancing
• Cloud scalability
• Monitoring
• Automated deployment

Scalability is especially important when the application handles real-time orders, inventory, payments, and logistics.
