Amazon Great Indian Festival 2026 Seller Playbook: Stock, Deals, Ads and Pacing

Amazon's Great Indian Festival is the longest of the Indian sale events and the one where preparation pays most, because Amazon's deal tools, FBA inbound limits and ad auctions all reward sellers who moved early. This playbook gives you the four-week countdown, the sale-week checks, the post-event clean-up, what tripped sellers in 2025 and a rupee budget example. It is a 2026 playbook refreshed yearly; every date sits in the "This year's dates" note so it can be updated without rewriting the page. Fees come first: read our Amazon seller fees guide before you set a deal price, and see our Amazon account management service if you want the event run for you.

What does the four-week countdown look like?

Amazon runs its festive deal submissions through Seller Central under Advertising, then Deals, and through Prime Exclusive Deals and coupons. Submission windows and FBA inbound cut-offs are announced inside Seller Central, not in press; the dates below are working assumptions you should replace with the ones in your account.

The one thing that catches sellers every year is the inbound cut-off. Amazon publishes a date inside Seller Central by which FBA stock must arrive at the fulfilment centre to be sellable on day one; stock that arrives after it may be received during the sale, or after. Ship early and split shipments so a delayed truck does not empty a hero ASIN. Our Amazon account health guide covers the metrics a rough sale week can damage.

What do you check during the sale?

• Every two to three hours on day one: spend against plan, Buy Box on festive ASINs, deal status (Amazon suspends deals that lose the Buy Box or run out of deal quantity), and stock cover on the top ten ASINs.
• Daily: ACoS by campaign against the break-even for that ASIN, not against last month's average. Cut placements below threshold; move budget to search. See the ACoS and TACoS glossary entries for the maths.
• Stock rule: pause ads on any ASIN under three days of cover. Amazon still charges the click on a listing that goes out of stock mid-session.
• Deal quantity: if a Lightning Deal is 100% claimed early, it is a sign the price was too low; do not add more quantity without checking margin.
• Returns and defects: keep an eye on A-to-z claims and negative feedback daily; a spike usually points at a packaging or size-chart problem you can fix the same day.

What does the post-event week look like?

1. Restore bids and budgets within 48 hours. Festive bids on normal traffic burn margin.
2. Reconcile. Match the settlement report against orders, refunds, FBA reimbursements and deal fees. Raise reimbursement cases for lost or damaged inbound and for customer returns not received; the windows are finite.
3. Returns. Fashion and lifestyle categories should budget for returns around 15% of orders (Techqueto's checklist number). Check returned units for grading; unsellable FBA returns need a removal order before storage fees accrue.
4. Cool down. Keep hero ASINs in stock so the rank gained during the sale holds; clear slow movers through Amazon's own later waves rather than deep coupons. Write the retro: units by ASIN by day, stock-out hours, ACoS by campaign, return rate by category.

What went wrong for sellers last year?

• The GST rate change landed mid-preparation. Medianama reported that the GST Council's 3 to 4 September 2025 decisions, which merged the four slabs into two main rates, left sellers holding stock invoiced at old rates, delayed pricing decisions and exposed them to billing mismatches during the peak. Keep tax as a separate line in your price sheet so a rate change is a formula edit.
• Fashion stocked to the wrong number. Redseer's first-leg read of festive 2025 (11 days from 22 September) put e-commerce GMV at ₹60,000 to ₹62,000 crore, up 20% to 22%, with smartphones and appliances contributing 60% to 65% and fashion growing in low single digits. Sellers who planned fashion stock to the headline growth carried inventory into November.
• Quick commerce took the small basket. Redseer saw quick commerce growing more than 120% through the season with no separate festive spike, meaning everyday categories sold there all season. Plan Blinkit, Zepto and Instamart alongside Amazon for those categories.

How do you pace a rupee ad budget?

Take a seller who normally spends ₹1,50,000 a month on Amazon Ads and sets aside ₹4,00,000 for a 12-day festive window: early access, the first ten days, and two days after. The shape below follows the same logic agency guides apply to Flipkart's sale (SW Cybernetics: about 1.5x normal in the pre-week, three to four times on the first two days, two to three times after), adjusted for Amazon's longer run.

The percentages are a starting shape. The fixed rule is the break-even: an ASIN netting 25% after fees loses money above a 25% ACoS however good the sale-week average looks. Our Amazon ads guide has the campaign structure and bid rules behind this table.

FAQ

When is the Amazon Great Indian Festival 2026? As of September 2026, it starts on 8 October with Prime early access from 7 October. Amazon has not published an end date; recent editions ran in waves through Diwali.

When do I submit festive deals on Amazon? Through Seller Central under Advertising and Deals, and via Prime Exclusive Deals and coupons. Windows are announced in your account, typically several weeks before the event; there is no public date.

What is the FBA inbound cut-off? Amazon posts a date inside Seller Central by which stock must be received to be sellable on day one. It is not published in press; ship early and split shipments.

How much stock should I hold? Agency guides suggest 1.5x to 2.5x normal cover on your top 20% of ASINs with a 30% buffer on hero products. Your own daily curve from last year is the better guide.

Do festive CPCs go up on Amazon India? Amazon publishes no CPC data. Agency guides report festive clicks at two to three times normal across Indian marketplaces, which is why budgets rise before the sale, not during it.

What should I do the day after? Restore bids within 48 hours, reconcile settlements against returns and reimbursements, raise cases inside the windows, and keep hero ASINs in stock so rank holds.
