Key takeaways

  • ONDC lets one seller listing reach buyers across Paytm, PhonePe, and dozens of other connected apps through a shared open protocol, instead of negotiating separate marketplace agreements.
  • Aggregator/seller-network listings cost ₹0–₹25,000 and go live in 1–2 weeks — the right starting point for most small and first-time ONDC sellers.
  • A middleware connector added to an existing Shopify, WooCommerce, or custom store runs ₹75,000–₹3,00,000 and takes 4–8 weeks, keeping the existing website untouched.
  • Only businesses onboarding other sellers under their own brand need a full custom Network Participant build (₹8,00,000–₹30,00,000+, 4–6 months) — single-seller businesses should avoid this tier.

Aggregator / Seller Network Listing — ₹0 to ₹25,000

List your catalog through an existing ONDC-registered seller platform. Setup in 1–2 weeks, with a 1–4% per-order commission instead of a large upfront cost. Best for small retailers and first-time ONDC sellers who want to test the channel before investing further.

Middleware / Connector Integration — ₹75,000 to ₹3,00,000

A connector layer maps your existing product and order APIs into ONDC-compliant calls. One-time build cost plus ₹10,000–₹40,000/month platform fee. Takes 4–8 weeks and preserves your existing storefront exactly as it is, adding ONDC as a new sales channel alongside it.

Full Network Participant / Custom BPP Build — ₹8,00,000 to ₹30,00,000+

A ground-up implementation of the full Beckn Protocol stack: discovery, order, fulfillment, cancellation, returns, and settlement APIs, plus Network Participant registration. Runs 4–6 months and is built for platforms and retail chains onboarding third-party sellers, not single-seller businesses.

How to Decide: A Three-Question Framework

Ask, in order: (1) Are you selling as one business, or onboarding other sellers under your brand? If it's just you, the full custom build is off the table. (2) Do you already have a working e-commerce backend with a product API? If yes, a middleware connector is your fastest path; if no, start with an aggregator listing while you build one out. (3) Does your business need custom fulfillment logic a generic connector can't express — multi-warehouse routing, regulated-category rules, subscription orders? Only then does the six-figure-plus custom build earn its cost.

Frequently asked questions

Is ONDC free to join?
Listing through an aggregator is close to free upfront, with a small per-order commission. Building your own connector or full Network Participant has separate development costs, outlined above.
Can I sell on ONDC without giving up my existing website?
Yes — a middleware connector adds ONDC as an additional channel while your existing website keeps running exactly as before.
How long does an ONDC integration take?
1–2 weeks for an aggregator listing, 4–8 weeks for a middleware connector, and 4–6 months for a full custom Network Participant build.
