ONDC for small sellers: should your business join?

Join ONDC as an extra channel if you already sell a product with proven demand and you have clean catalogue data. Do not join expecting the network to create demand for you. ONDC is an open network, not an app and not a marketplace you register on directly.

You join through a seller app, called a Seller Network Participant. That app sets its own charges. ONDC itself publishes no single seller fee, and that one fact shapes the whole decision.

The short version

ONDC reports on its public pages that more than 250,000 sellers participate and more than 300 network participants are connected. Treat those as ONDC's own reported scale, date stamped to November 2026, not as a promise of orders for any one seller.

How the network actually works

In a normal marketplace, one company owns the buyer app, the seller dashboard, the payment flow and often the delivery network. ONDC separates those roles.

A buyer app is where the customer places the order. A seller app is where your catalogue lives and where orders reach you. A logistics provider moves the parcel. A gateway connects the different apps so they can talk to each other using the same protocol.

Your direct relationship is with your seller app. According to ONDC, a Seller Network Participant connects sellers to the network, digitises the catalogue and disburses payments to sellers. That is why the seller app's fee, service quality and settlement period matter more than any headline about the network itself.

There are two kinds of seller nodes. A Marketplace Seller Node hosts many sellers on one node, which is the route most small sellers take through a seller app. An Inventory Seller Node is run by a business selling its own goods. Most owners reading this will use the first route.

This structure has a practical consequence. If orders are low, the problem could be your catalogue, your seller app's reach, your prices, your delivery area, or weak demand for the product itself. There is no single ONDC support desk that fixes all of that. Your seller app is your first point of contact.

What it really costs

This is the section most guides get wrong. They quote one commission band and present it as the total cost of selling. In reality, at least three different parties charge you, and each sets its own price.

ONDC does not publish one fee for sellers. Each seller app sets its own charges and settlement period, so both must be agreed in writing before you sign.

Secondary market sources, checked in November 2026, give ranges that help you budget. They are ranges from seller apps and guides, not ONDC tariffs. Seller app subscriptions for small sellers are reported around Rs 999 to Rs 2,999 per month. Retail buyer app commissions are reported around 5% to 10%. Food buyer app commissions are reported around 3% to 5%. Network logistics are reported around Rs 45 to Rs 80 per shipment under 500 grams.

Use those ranges only to build a first estimate. Then replace every range with the actual figure your shortlisted seller app gives you in writing.

The rule is simple: compare total cost per delivered order across channels, not the headline commission. A channel with a 5% commission and Rs 80 logistics can cost more than a channel with a 10% commission and Rs 45 logistics, once returns and subscriptions are added.

Who can sell, and the GST position

Most sellers join with a GSTIN. There is also a narrow route for sellers who are not GST registered.

Since 1 October 2023, a seller whose turnover is within the GST registration limit can declare PAN on the GST portal and take an enrolment number. With that number, the seller can sell goods through e-commerce in one state only. Inter state sales are not allowed on this route. This position comes from Notification 34/2023 Central Tax.

Composition dealers may also sell goods through e-commerce operators from 1 October 2023, within their own state.

Read those limits carefully. If most of your orders would need to go to other states and you have no GSTIN, the enrolment number route does not cover you. In that case, take GST registration first or stay with channels that fit your current status.

Food sellers need one extra paper: an FSSAI registration or licence number, matched to the kind of food business you run. Our guide to which FSSAI licence you need and what it costs sets out the categories.

Papers and steps to join

Work through these steps in order.

1. Open the seller side participant list on ondc.org and pick a seller app that serves your category and your city.
2. Complete KYC with PAN, GSTIN or enrolment number, bank account details and IFSC.
3. Add business details, including delivery time and return policy.
4. Upload your catalogue with product name, clear photos, MRP, selling price, stock and delivery area. Add weight for every product, because logistics pricing depends on it.
5. Agree the seller app fee and settlement period in writing before you go live.
6. Ask the seller app about MSME TEAM support for your business.

The Kerala Directorate of Industries page on ONDC corroborates the same onboarding set: business details with GSTIN and bank account, product details with delivery time and return policy, and KYC with ID proof, address proof and a cancelled cheque.

Catalogue quality decides whether the channel works. A listing with poor images, no weight, the wrong subcategory and no stock figure will not sell, on ONDC or anywhere else. Treat the catalogue work as the real cost of joining. If you are also weighing the large marketplaces, read our comparison on selling on Amazon, Flipkart and Meesho alongside this article.

Support that exists: MSME TEAM

The MSME TEAM initiative runs from 2024 to 2027. It channels government support through seller apps to help micro and small enterprises with catalogues, account management, logistics and packaging. The programme was described in a PIB backgrounder dated 4 January 2025 and is also listed by the Kerala Directorate of Industries.

You do not apply for this support on a separate portal in the normal course. You ask your seller app what TEAM support it can pass on to you, and what you need to provide to get it. Ask before you sign, because support is one of the real differences between seller apps.

A worked example: what one month actually costs

Take a Jaipur home textiles seller with turnover of Rs 42 lakh. The business already sells through its shop and WhatsApp. It tests ONDC with bedsheet sets at an average order value of Rs 500 and 600 orders in a month.

Monthly online sales: Rs 500 x 600 = Rs 3,00,000.

Now the costs, using the midpoints of the secondary ranges above. These are illustrative figures for one seller app quote, not an ONDC tariff.

Total cost as a share of sales: Rs 58,999 divided by Rs 3,00,000 = 19.7%.

The lesson is in the split. The commission line is Rs 21,000 of the Rs 58,999. Logistics, at Rs 36,000, is the bigger number. A seller who compares only commission percentages would miss most of the bill.

The second question matters as much as the first. Are these 600 orders extra orders, or orders that would have come through the shop and WhatsApp anyway? If they are extra, a 19.7% channel cost may be worth paying. If they are the same orders moved to a costlier route, it is not.

Choosing a seller app: six questions to ask

Since the seller app is your real counterparty, choose it the way you would choose any service provider. Ask these six questions, and prefer written answers.

First, what is your full charge: subscription, any per order fee, and any charge for catalogue work or account management? Second, what is your settlement period, counted from delivery or from order placement? Third, which buyer apps and logistics providers do you work with in my category? Fourth, who handles a customer complaint or a return dispute, and what evidence do you need from me? Fifth, what MSME TEAM support can you pass on to my business, in specific terms? Sixth, if I leave, how do I take my catalogue data and order history with me?

Notice what these questions do. They move the conversation from the network's promise to the app's contract. Two apps can put you on the same network and give you entirely different economics and service. The app that answers clearly, in writing, at a fee you have priced into your margins, is usually the right starting point even if its headline charge is not the lowest.

Start small once you choose. Put your best 20 SKUs live, run the channel for a full month, and compare cost per delivered order against your other channels using real bills, not estimates. Then decide whether to expand the catalogue or exit. A one month test with real numbers is worth more than any projection, including the worked example in this article.

Should you join? A decision framework

• If your product already sells through your shop, WhatsApp or another marketplace, ONDC is a low cost extra pipe. Test it with your best 20 SKUs first.
• If you have no proven product yet, fix demand first. A new channel does not repair a product nobody wants.
• If you sell food locally, compare the food commission range against your current aggregator bill, line by line, including delivery and returns.
• If most of your orders need inter state shipping and you have no GSTIN, the enrolment number route does not cover you. Sort out registration first.
• If your catalogue data is messy, clean it before you join. The same cleaned catalogue will also improve your other channels, and it is the base work in digitising your business.

Common mistakes

Signing with the first seller app. Fees and settlement periods differ by app. Get both in writing from at least two apps before you choose.

Pricing off the commission headline. Logistics, returns and the subscription often cost more than the commission, as the worked example shows.

Uploading a weak catalogue. No weight, poor images and the wrong subcategory will make a workable channel look dead. Fix the data before you judge the channel.

Treating listing as marketing. Listing routes existing demand to your catalogue. It does not create demand. Your own customer base, shop traffic and WhatsApp list still do that work. The digital tools that support this work are covered in our tools guide.
