ONDC Integration
Your catalogue and stock connected to the ONDC network so buyers on any ONDC-linked app can find and order from you, without you building or maintaining a separate app for each one. Built and run by GullySystem.
Why Selling on One More App Is Not the Same as Joining a Network
ONDC is not a single marketplace app you list on like a normal aggregator. It is a shared protocol that many buyer apps and logistics providers connect to, so joining means your catalogue, order and fulfilment systems need to speak that protocol correctly, and a listing that looks fine on your own site can fail silently on the network if the technical format is wrong.
What ONDC Integration Involves
Seller Registration Through a Network Participant
Your business is registered and verified through a seller-side network participant, since a business does not connect to ONDC directly on its own.
Catalogue Published in Network Format
Your product catalogue is formatted and published to meet ONDC's catalogue and pricing specification, so it displays correctly across different buyer apps.
Order and Fulfilment Sync
Orders placed through any ONDC buyer app land in the same order queue as your other channels, rather than a separate panel to check.
Logistics Through the Network
Delivery can be fulfilled through ONDC's own logistics participants where available, or through your existing courier arrangement where you prefer to keep it.
An Example: A Regional Grocery Chain Reaching New Buyer Apps
A regional grocery chain wants to be discoverable on the ONDC network without building or promoting an app of its own for every city it serves. Registering through a seller-side network participant, publishing its catalogue and stock in the required format, and connecting order intake to its existing order queue means a buyer on any ONDC-linked shopping app can find and order groceries from the chain's nearest servicing store, with the order arriving the same way a website order would.
What Shapes the Cost and Timeline of an ONDC Connection
- How large and how frequently changing your catalogue is, since it must stay in sync with the network format
- Which seller-side network participant you register through and their own onboarding process
- Whether you use ONDC's logistics network or keep your existing courier arrangement
- How your current order and stock systems need to be adapted to publish correctly
- Verification and documentation requirements set by the network participant, which are outside our control
Frequently asked questions
Is ONDC worth it for a small or regional business?
It can be, particularly for reaching buyers you would otherwise need your own app or heavy advertising to reach. It makes most sense once your catalogue and order systems are stable enough to publish correctly, since a shaky catalogue causes more problems on a network than on your own site.
What determines the cost of connecting to ONDC?
The size and complexity of your catalogue, and how much your existing order and stock systems need to be adapted to publish in the network's required format, are the main drivers.
What usually takes the longest to complete ONDC onboarding?
Verification and onboarding through the seller-side network participant, since that approval process is run by them, not by us.
Can our existing online store or POS stay in place alongside ONDC?
Yes, ONDC integration is built to sit alongside your existing systems, publishing the same catalogue and receiving orders into the same queue rather than replacing anything.
Who owns our seller account and catalogue on the network?
You do, as the registered seller. The network participant handles the technical connection, but the account, catalogue and order data belong to your business.
What do we need before we can start?
A catalogue in reasonable order, a decision on which seller-side network participant to register through, and your existing order and stock systems ready to be connected.
