How to Sell on BigBasket: Supplier Onboarding Guide (2026)

How to Sell on BigBasket in 2026

Last verified 22 September 2026. BigBasket's own supplier-facing pages returned limited readable content to automated checks, so this guide states plainly what's confirmed versus sourced from third-party seller-onboarding guides.

BigBasket, now under Tata Digital, is one of India's largest online grocery platforms. Like Blinkit and Zepto, it doesn't run instant self-serve seller signup — it sources through a supplier/vendor procurement process, evaluated by category before approval.

The Vendor Portal: BB Sambandh

BigBasket's supplier portal, confirmed to exist at nucleus.bigbasket.com ("BB Sambandh"), is where the onboarding process begins. The portal resolved but returned limited readable content, so screen-by-screen process detail isn't independently confirmed — the steps below reflect what's reported by third-party seller-onboarding guides.

Who Can Apply

Third-party sources describe four supplier categories BB Sambandh accepts applications from:

• Manufacturers
• Distributors
• Farmers
• Retailers

This is broader than a typical D2C-brand-only vendor programme, reflecting BigBasket's grocery and fresh-produce category mix.

Documents You'll Likely Need

Based on third-party guides (not confirmed on an official BigBasket page):

1. GSTIN and GST certificate — see our GST registration guide if you need one.
2. PAN card.
3. Bank account details for payments.
4. FSSAI license, if you supply food, grocery or perishable items.
5. Brand authorization letter, if you're not the registered brand owner.

Registration Process: What's Reported

1. Apply through BB Sambandh with your business name, structure, and contact details.
2. Choose your supplier category — manufacturer, distributor, farmer, or retailer.
3. Submit GST and PAN details, plus your bank account.
4. Upload supporting documents, including FSSAI if applicable.
5. Wait for evaluation. BigBasket reportedly reviews product quality, pricing, inventory capability, and category fit before approving new suppliers — no fixed timeline was confirmed.

Commission and Terms

We could not confirm a published commission rate card. Third-party guides describe negotiated, category-specific commercial terms rather than a fixed public percentage — similar to Blinkit's category-manager-negotiated model. Don't take a specific number from a third-party blog as your actual rate; that only shows up in your own supplier agreement once approved.

BigBasket vs Blinkit and Zepto — What's Different

BigBasket's supplier model is closer to Blinkit and Zepto than to Amazon or Flipkart — all three run evaluation-based onboarding rather than instant self-serve listing. The practical difference is scope: BigBasket accepts farmers and general retailers as supplier categories alongside manufacturers and distributors, reflecting its grocery and fresh-produce focus, whereas Blinkit and Zepto's vendor programmes lean more toward D2C brands and FMCG distributors. If your product is fresh produce or a grocery staple rather than a packaged D2C brand, BigBasket's supplier categories may be a more natural fit than either.

Getting Started

If you don't have a GSTIN yet, get that in place first — see our GST registration guide. Once you have your terms confirmed, use the Marketplace Profit Calculator to model your margin, and the GST Calculator to check the tax math on your supplier invoices. If you're supplying multiple BigBasket warehouses across states, see our quick-commerce GST and dark-store registration guide for the Additional Place of Business (APOB) mechanics.
