Open Network for Digital Commerce ONDC: Architecture and Aims

The Open Network for Digital Commerce is an Indian initiative that turns online buying and selling into a protocol-led network rather than a set of walled-garden platforms. Launched by the Department for Promotion of Industry and Internal Trade in 2021 and incorporated as a private non-profit company in 2022, the Open Network for Digital Commerce or ONDC lets any buyer-side app discover and transact with any seller-side app, as long as both follow the open protocol. The aim is to reduce the dependence of Indian merchants on a few dominant marketplaces and to give consumers more choice without locking them into a single application.

Origins of ONDC

India’s e-commerce market grew rapidly through the 2010s, but the share of digital retail concentrated in two or three platforms. Sellers paid high commissions, faced opaque ranking algorithms, and could be delisted at platform discretion. Small kirana stores were excluded from digital commerce because they lacked the resources to integrate with multiple platforms. The DPIIT, working with industry leaders and the Quality Council of India, proposed a network-based alternative inspired by the UPI model where any bank app can transact with any other through a common rail.

ONDC was formally incorporated as a Section 8 company with equity contributions from several public sector banks, depositories, and NABARD, ensuring independence from any single private participant.

Network Architecture

The ONDC architecture has four roles. Buyer applications such as Paytm, Magicpin, and various stand-alone ONDC apps serve consumers. Seller applications such as Mystore, eSamudaay, and platforms used by small businesses serve merchants. A logistics network handles fulfilment, and a gateway routes search and select messages between the buyer and seller sides.

When a consumer searches for a product, the buyer app broadcasts the query through the gateway to all seller apps that have indicated relevant catalogue presence. Sellers respond with matching listings. The consumer sees aggregated results from multiple seller apps within one buyer app. After selecting an item, the order is placed through the protocol, payment is processed using the UPI rails or other supported methods, and logistics integration arranges delivery.

The protocol used is Beckn, an open specification originally built for mobility commerce and now extended to retail, food, grocery, and services.

Interoperability and the Network Effect

The key idea is interoperability. Unlike a marketplace where buyers and sellers must both be on the same platform, ONDC lets them live on different applications and still transact. This is similar to how a Yes Bank account holder can pay a State Bank account holder through UPI without either user knowing or caring about the other’s bank.

Interoperability shifts power away from platforms because their value to merchants comes from access to buyers. If buyers can come through any app, no single platform can dictate commission rates or visibility. Sellers benefit from lower switching costs. Buyers benefit from broader product discovery within their preferred application.

How ONDC Aims to Break Dominance

The dominance of a few marketplaces has three pillars: customer acquisition through repeated marketing spend, data lock-in from purchase history, and supplier lock-in from exclusive contracts. ONDC weakens all three.

Customer acquisition becomes cheaper because new buyer apps can plug into the existing seller pool from day one. Data lock-in eases because the protocol allows consent-based portability of order history. Supplier lock-in fades because a seller listing once becomes visible across every buyer app on the network.

The initiative aligns with the broader policy direction of digital public infrastructure, alongside Aadhaar, UPI, and the data empowerment frameworks defined under the Data Protection Act 2023.

Current Status and Limitations

By early 2026, ONDC supports retail, food and beverage, grocery, mobility, and beauty categories across most metros and many tier-two cities. Monthly transactions have crossed several million but remain small compared with the leading marketplaces. Order completion rates, return policies, and dispute resolution mechanisms have been points of friction.

Logistics integration remains a weak link. Buyer and seller apps may both be on ONDC, but if the logistics partner is not, fulfilment falls back on traditional courier arrangements. Quality control is decentralised and depends on the seller app’s onboarding standards. Standardised buyer protections similar to those on closed marketplaces are still maturing.

Governance and Funding

The non-profit Section 8 status is meant to prevent any commercial bias. Network participants pay nominal participation fees rather than transaction commissions, which is a structural difference from marketplaces. Funding has come from equity contributions by NABARD, the State Bank of India, the Bank of Baroda, and several depositories.

The future depends on whether buyer applications can match the user experience of established marketplaces while keeping the merchant side broad and reliable.

FAQs

What does ONDC stand for?

Open Network for Digital Commerce, an Indian initiative that creates an interoperable protocol for e-commerce.

Is ONDC a marketplace?

No. It is a network protocol. Marketplaces are individual applications. ONDC connects different marketplaces and apps so a buyer on one can transact with a seller on another.

When was ONDC launched?

The initiative was announced in 2021 and the Section 8 company was incorporated in 2022. Public soft launch was in late 2022 in Bengaluru.

Who owns ONDC?

ONDC is a non-profit Section 8 company with equity from public sector banks, depositories, and NABARD. It is governed independently of any single private participant.

What is the Beckn protocol?

An open specification for decentralised commerce, originally designed for mobility, now used by ONDC for retail, food, grocery, and services.

How does ONDC handle payments?

Through standard payment rails including UPI, debit and credit cards, and net banking. Payments flow either through the buyer app or directly to the seller’s settlement account.

Can a small kirana store join ONDC?

Yes. Onboarding happens through a seller-side application that already participates in the network. Many seller apps focus specifically on small and informal retailers.

Does ONDC replace marketplaces?

No. Marketplaces continue to exist. ONDC offers an alternative model and many of the marketplace logistics and seller services participate as ONDC node operators themselves.
