Last Diwali, Indian ecommerce hit ₹1.2 lakh crore in festive season sales. The brands that captured disproportionate share weren’t the ones with the biggest budgets — they were the ones that started preparing in August.
Here’s what goes wrong when you start late:
Inventory stockouts — Manufacturers are backlogged by September. If you haven’t placed orders by mid-August, you’re competing for remaining capacity.
Ad costs spike 40-60% — CPMs on Meta and Google start rising in September as every brand increases spending. Early campaigns build pixel data at lower costs.
Logistics slots fill up — 3PLs and courier partners allocate capacity in advance. Late brands get slower delivery times.
Creative fatigue — You need 20-30 ad creatives for the full season. Producing these in 2 weeks leads to mediocre work.
The 90-Day Diwali Prep Calendar
Phase 1: Foundation (August 1–31)
Week 1-2: Inventory planning — Analyze last Diwali data (or competitor research if first year). Identify top SKUs, bundle opportunities, and gift sets. Place manufacturing orders NOW.
Week 3: Website audit — Speed test your site. Fix mobile UX. Set up festive landing pages. Test checkout flow with 10 real users.
Week 4: Creative production — Brief your creative team (or start generating). Need: 10 video creatives, 10 static ads, email templates, WhatsApp broadcast templates, website banners.
Phase 2: Build-Up (September 1–30)
Week 1-2: Launch early-bird campaigns — ‘Diwali Early Access’ at 10-15% discount. Goal: build retargeting audiences and collect emails/WhatsApp subscribers before CPMs spike.
Week 3: Test and optimize — Run A/B tests on creatives, offers, and landing pages. Kill underperformers. Scale winners.
Week 4: Logistics dry run — Ship test orders through your entire fulfillment chain. Verify packaging quality for gift items. Confirm COD verification flows are working.
Phase 3: Peak (October 1 – Diwali)
Week 1: Full launch — Activate all campaigns. Maximum ad budget deployed. Email/WhatsApp sequences triggered.
Week 2-3: Daily optimization — Monitor ROAS hourly during peak days. Kill low-performing ad sets. Increase budget on winners. Handle customer queries within 30 minutes.
Post-Diwali (1 week after): Clearance — Run clearance sales on remaining inventory. Target cart abandoners with maximum discounts. Begin post-festive retention campaigns.

Festive Pricing Strategy
Don’t just slap discounts everywhere. Use a tiered approach:
Early Access (September) — 10% off for email/WhatsApp subscribers. Creates urgency and builds your remarketing pool.
Main Sale (Diwali week) — 15-25% off. Match or beat marketplace pricing on hero products. Bundle deals for higher AOV.
Flash Sales (2-3 during peak) — 30-40% on select products for 6-12 hours. Creates social buzz.
Post-Diwali Clearance — 40-50% on remaining festive inventory. Better to sell at cost than hold dead stock.
Common Diwali Mistakes
Going heavy on discounts, light on creative — Your 20% off means nothing if the ad doesn’t stop the scroll. Invest in creative first.
Ignoring mobile UX — 80%+ of festive traffic is mobile. If your mobile checkout takes more than 3 taps, you’re losing sales.
No post-purchase follow-up — Festive buyers are gift buyers, not necessarily your target customer. Convert them to repeat buyers with targeted post-purchase sequences.
Running out of stock on day 3 — Over-order your top 3 SKUs by 30%. Understocking costs more than overstocking.
