How to Price Products When You Sell on Multiple Marketplaces

The most common pricing mistake among multi-channel Indian sellers is using a single price across every platform. It feels simpler and avoids customer complaints about price differences. But it is almost always wrong — because each platform has a different commission structure, fulfilment cost, and advertising baseline. A price that is profitable on Shopify may barely break even on Amazon.

Here is how to build a pricing model that actually accounts for where each sale happens.

Start with Your Floor Price

Your floor price is the minimum you can charge and still survive — covering the cost of goods (COGS), packaging, inbound logistics, and GST. Nothing else. This is your absolute bottom before any channel cost is applied.

Calculate it per SKU, not as a blended average. A product that costs ₹200 to make and pack, with a COGS-to-selling-price ratio assumption of 30%, has a floor of ₹200. But if your packaging cost varies by size tier and your inbound freight changes by season, your floor can shift by 8–12% depending on the shipment. Track it per production batch.

Add Channel-Specific Costs on Top

Each channel has a cost stack that you must add above the floor to reach a break-even price for that channel. For Amazon FBA, this includes the referral fee, FBA fulfilment fee, and a storage provision. For Flipkart with seller-managed fulfilment, this includes the referral fee plus your own courier cost. For Shopify, this includes payment gateway fees, courier cost, and your own advertising cost to drive traffic.

Running the numbers on a ₹500 product across channels illustrates why a uniform price often fails. On Amazon FBA in a 15% referral category with a ₹65 fulfilment fee, your platform cost is around ₹140 (₹75 referral + ₹65 fulfilment). On Shopify with a Shiprocket courier at ₹60 and a 2% Razorpay fee, your channel cost is ₹70. Using one price to cover both means you are either over-priced on Shopify or under-priced on Amazon.

Advertising Cost: The Invisible Pricing Variable

Advertising is where most sellers's pricing models break down. They calculate price assuming zero or very low ad spend, launch the product, find they need to bid aggressively to get visibility, and then discover the margin they thought they had is gone.

A more disciplined approach: set a target ACoS (Advertising Cost of Sales) before you price, and price in that cost from day one. If you expect to run Sponsored Products at a 20% ACoS for the first 90 days while the listing gains organic rank, that 20% needs to be in your price from launch. Pricing with a 10% advertising provision and then spending 25% is the reason many sellers are unknowingly selling at a loss.

Price Parity Rules and How to Navigate Them

Amazon has a price parity policy — you cannot sell the same product cheaper on another platform than you sell it on Amazon. Violation of this policy can result in listing suppression or seller account action. Flipkart has similar provisions.

This does not mean you must charge the same price everywhere. It means your Amazon price must be at or below your other channel prices. In practice, many sellers price Shopify slightly higher than Amazon (the Shopify customer is paying for the brand experience, not just the product) and keep Amazon prices competitive. This is allowed under the parity rules because Amazon is not more expensive — it is at parity or below.

Seasonal and Competitive Price Adjustments

During sale events — Big Billion Days, Great Indian Festival, end-of-season sales — platforms expect deep discounts. The question sellers must answer in advance is: what is the minimum discount we can offer without selling below break-even, and which SKUs can we afford to discount more because they carry a higher margin buffer?

Prepare a pricing sheet for each major sale event three weeks before it runs. Map each SKU to its floor price, its standard platform price, and its sale floor (typically 10–15% above COGS with no advertising). Then negotiate your discount strategy with the category team from a position of knowledge rather than guessing what you can afford.

Repricing and Automation

Manual pricing at scale is unmanageable. For Amazon specifically, automated repricing tools can adjust your Buy Box price in real time based on competitor pricing while keeping you above a minimum floor you set. These tools prevent the classic race to the bottom — sellers undercutting each other by ₹1 until the product is unprofitable for everyone — by enforcing a hard lower bound.

Set your repricing floor at your break-even price for that channel plus a minimum acceptable margin (say 8%). The repricer can compete aggressively above that floor but will never go below it. Review and adjust the floor quarterly as your costs change.
