What is ONDC?

ONDC, or Open Network for Digital Commerce, is an open network initiative created to make digital commerce more interoperable and less dependent on closed marketplace platforms.

In a traditional e-commerce marketplace, the buyer, seller, catalogue, order flow, logistics options, and payment journey are usually controlled within one platform. ONDC changes this model by allowing different buyer apps, seller apps, logistics providers, payment providers, and technology partners to connect through common network protocols.

This means a buyer using one ONDC-enabled app may be able to discover and purchase products or services listed by sellers onboarded through another ONDC-enabled seller app. The seller does not need to be present on the same platform as the buyer. This network-led model is designed to democratise digital commerce, particularly for small retailers, local merchants, D2C brands, mobility providers, food businesses, and service providers.

How ONDC Works

ONDC separates the different parts of a commerce transaction so that multiple participants can interact across the network.

A simplified ONDC flow looks like this:

• Seller onboarding: A seller lists products or services through a seller network participant.

• Buyer discovery: A buyer searches for products through a buyer app.

• Network matching: The ONDC protocol enables discovery across participating sellers, even if they are not on the buyer app.

• Order placement: The buyer places the order through their app.

• Fulfilment: Logistics, delivery, cancellation, returns, settlement, and support are handled through network-defined processes and participants.

The key idea is interoperability. ONDC is not just another online marketplace. It is a protocol-based network where commerce participants can plug in and compete on service, pricing, reach, customer experience, and fulfilment quality.

Why ONDC Matters for Businesses

ONDC is important because it may reduce the platform dependency that many sellers face in digital commerce. On large closed marketplaces, sellers often depend on the same platform for discovery, ranking, logistics, pricing visibility, customer ownership, and promotional access. ONDC creates a more open structure where sellers can be discovered across multiple buyer-facing apps.

For small businesses, this can mean:

• Wider digital reach without depending on one marketplace.

• More choice in logistics, seller tools, and buyer-facing channels.

• Better ability to build an online presence through network participants.

• Potentially lower barriers to entering digital commerce.

For larger businesses and fintechs, ONDC creates opportunities around seller financing, embedded payments, loyalty, reconciliation, digital cataloguing, credit, logistics enablement, and B2B commerce infrastructure.

Business Example and Practical Relevance

Example:

A local grocery store signs up through an ONDC seller app. A customer using a separate buyer app searches for grocery items and discovers the store’s catalogue. The order is placed through the buyer app, fulfilled through a logistics participant, and settled as per the network flow.

Why this matters:

• The seller does not need to be directly listed on every buyer app.

• The buyer gets more seller choice.

• Technology providers can build specialised tools for sellers, buyers, payments, logistics, and reconciliation.

• Commerce becomes more modular.

For businesses, ONDC should be seen as infrastructure. Its value is not just online sales, but the possibility of building interoperable commerce workflows across discovery, ordering, payment, credit, fulfilment, and post-sale service.
