Flipkart Big Billion Days: a seller's preparation guide

Big Billion Days can bring more orders in a week than a normal month. It can also leave you with stockouts on your best sellers, deals that sold well but lost money, and a wave of returns a few weeks later. The difference usually comes down to preparation that starts well before the sale.

This guide works for Big Billion Days and for Flipkart's other large sale events through the year.

Start six to eight weeks before the sale

Sale dates are usually announced closer to the event, but the work cannot wait for that. Stock takes time to produce and reach warehouses, listings take time to fix, and deal pricing needs proper calculation. Starting late is the most common reason sellers miss their best sale of the year.

Fix your catalog first

Traffic during the sale is expensive to buy and easy to waste. Before you spend a rupee on ads, make sure your top products are ready to convert:

• Correct categories and complete attributes, so products appear in filtered searches
• Clear titles that say what the product is, in the words customers actually use
• Good images, including size, usage and close ups
• Fresh reviews and answers to common customer questions

Plan stock around your best sellers

Look at last year's sale and your recent sales trend, then plan inventory for the products most likely to sell out. Flipkart sets deadlines for stock to reach its warehouses before big events, so work backwards from those dates. Running out of stock on day one costs you sales and can also hurt how your product ranks after the sale.

Price deals that protect your margin

A deal that sells thousands of units at a loss is not a win. Before you agree to any discount, work out your real margin per unit after Flipkart's commission and fees, shipping, packaging, the expected return rate and your ad cost. Then decide how deep you can go. Often the smart move is to discount a few hero products heavily to win traffic, while keeping healthier prices on the rest of your range.

Plan your ad budget by day

Competition for ad space peaks during the sale, and so does the cost. Plan budgets day by day rather than as one big number, put more behind products that are in stock and priced to convert, and check performance several times a day during the peak. Pause what is not working quickly instead of waiting for the weekly review.

Prepare for returns after the sale

Returns usually rise in the weeks after a big event. Keep an eye on the reasons customers give, and reconcile returns properly. Items that come back damaged or do not come back at all can often be claimed, but only if someone checks.

Review what really happened

Once the dust settles, look beyond total sales. Check which products made money after all costs, which deals only bought volume, where you ran out of stock, and what customers complained about. That review is what makes next year's sale better than this one.
