About ONDC | Open Network for Digital Commerce. In India, more than 12 million sellers earn their livelihood by selling or reselling products and services. However, only 15,000 of these sellers (0.125% of the total) have enabled e-commerce. ONDC recognises the unique opportunity to increase e‑retail penetration from the existing 4.3% to its maximum potential in India. ONDC mission is to dramatically increase e-commerce penetration in the country by enabling population-scale inclusion of all types and sizes of sellers.

ONDC aims to democratize access to commerce, by decoupling buyers, sellers and other stakeholders in the commerce ecosystem and making them interoperable through a common network. ONDC Open Commerce is an open source repository that provides code to the network participants in a way that they find it easy to integrate into the ONDC network, perform requisite commerce operations and never have to worry about integration, scalability and security.
