11.11 vs 12.12 vs 9.9: which sale pays back in 2026

By Mai Influence

Bangkok brand teams treat 9.9, 11.11, and 12.12 as if they were the same event with different dates. They are not. Creator rates, boost costs, cart sizes, and returns all behave differently across the three, and the honest choice for most SMBs in 2026 is to pick one and go hard, not to spread half a budget across all three. Here is what the numbers look like on the Mai Influence roster this year, plus what actually clears inventory versus what only clears the marketing budget.

What the three sales are, in one paragraph

9.9 is the Shopee-and-Lazada warm-up, positioned as back-to-work and back-to-school. 11.11 is the Alibaba-heritage headline event, still the biggest cart-value day of the year across TikTok Shop, Shopee, and Lazada in Thailand. 12.12 is the year-end clearance day, part gift shopping, part retailer margin-recovery. All three land on TikTok Shop, Shopee, Lazada, and increasingly on brand DTC sites via LINE Shopping. Instagram and Facebook do not run the sale mechanics themselves but carry the creative that drives cart-adds.

Creator rate multipliers by event

Rates rise for all three, but not evenly. The pattern we see on Bangkok briefs this year:

  • 9.9: 1.1x to 1.2x of the creator's base rate. Books close 10 to 14 days out. Plenty of inventory left across nano and micro tiers even at T-minus 5 days.
  • 11.11: 1.3x to 1.6x of base. Top-tier creators lock briefs 4 to 6 weeks out. Nano and micro creators still take last-minute briefs but at the top of the range.
  • 12.12: 1.15x to 1.3x of base. Books close 2 to 3 weeks out. Availability is decent because a lot of top creators are travelling for New Year by the second week of December.

For a mid-tier creator at 18,000 THB base for one Reel plus one carousel, that is roughly 21,000 THB at 9.9, 27,000 THB at 11.11, and 22,000 THB at 12.12. The 11.11 premium is real and worth budgeting for if the platform economics work. If you are still setting the base rate, our rates guide has the fuller follower-tier bands to work from.

Boost costs and cart-size lifts

Paid boost on creator posts around the three sales moves in the opposite direction from what most planners expect. CPMs are highest on 11.11 week because every brand is bidding. Cart-add rate is also highest, so blended CPA can still work, but the margin for error on creative is thin.

Rough Bangkok ranges we see in wrap reports this year:

  • 9.9: CPM 220 to 320 THB on Meta partnership ads, 180 to 260 THB on TikTok Spark Ads. Cart-add rate about 1.4x a normal week.
  • 11.11: CPM 380 to 520 THB on Meta, 300 to 420 THB on TikTok. Cart-add rate 2.2x to 2.8x a normal week.
  • 12.12: CPM 260 to 360 THB on Meta, 220 to 300 THB on TikTok. Cart-add rate 1.6x to 1.9x.

The 11.11 CPM premium is roughly 65 percent above baseline, and the cart-add lift is only about 150 percent, so your creative and offer have to be sharper than usual to keep the CPA math honest. On 9.9 and 12.12 the boost math is more forgiving, which is often why smaller brands quietly get better ROI on the shoulder events. The mechanics we covered in boost budget ratios still apply, just with the sale multipliers layered on top.

Which event clears which inventory

This is the part planners skip. The three sales sell different categories at different intensities.

  • 9.9 skews toward stationery, small electronics, home goods, and beauty basics. Average cart 800 to 1,400 THB on Shopee, 1,000 to 1,600 THB on TikTok Shop.
  • 11.11 skews toward beauty premium, fashion, larger electronics, and gift-worthy items. Average cart 1,600 to 3,200 THB across platforms.
  • 12.12 skews toward gifting, food and drink, and year-end apparel. Average cart 1,200 to 2,000 THB.

If you sell a beauty premium SKU at a 1,200 THB price point, 11.11 is the obvious call, and the creator premium pays back. If you sell a 350 THB pantry SKU, 9.9 will likely clear more units per THB of creator spend than 11.11 will, because the shopper mindset on 9.9 favours basket-filling. If you sell gift bundles, 12.12 is the natural fit, and the softer creator market means you can book better talent per THB than at 11.11.

Timing the brief

Working backwards from the sale date, the honest calendar for a mid-sized creator brief:

  • T-minus 6 weeks: shortlist creators and open offers, especially for 11.11.
  • T-minus 4 weeks: lock briefs, confirm sampling, confirm boost rights and whitelisting.
  • T-minus 2 weeks: shoot day, first-cut delivery.
  • T-minus 1 week: approvals, revisions, approval SLAs matter here more than any other week.
  • T-minus 3 days: first teaser post, warming the audience without spending the punch.
  • Sale day: main post live at the platform's peak hour, which in Bangkok is roughly 20:00 to 22:00 local for TikTok and 19:00 to 21:00 for Instagram.
  • T-plus 1 to 3 days: partnership ads scaled behind the winning creative, not the average creative.

Skip any of these steps and the sale premium you paid on the creator fee gets wasted on a post that goes live too late or without paid amplification behind it.

The honest pick for most Bangkok SMBs

If your monthly marketing budget is under 200,000 THB and you cannot fund all three sales properly, the ranking most years is 11.11 first, 9.9 second, 12.12 third, but this only holds if your SKU fits the 11.11 cart profile. If it does not, invert the order. A pantry brand should treat 9.9 as its Super Bowl and let 11.11 run on organic and light boost. A gifting brand should hold budget for 12.12 and treat 11.11 as a warm-up.

One sale, run correctly, beats three sales run at 30 percent effort each. The creator premium is only wasted if the calendar and the boost stack are not ready for it.

Returns and the post-sale cleanup

Return rates in Thailand on mega-sale weeks sit at 8 to 14 percent on fashion, 4 to 7 percent on beauty, and 2 to 4 percent on electronics. 12.12 has the highest return rate of the three because gift buyers are less certain of the recipient's fit. This matters for the creator brief because usage rights on the post should run at least 60 days past the sale, not just 30, so you have the creative to defend against negative comments and to re-run on retention audiences after the return wave settles. The usage rights piece covers the negotiation angle.

The Mai Influence angle

Every brief on the platform tags the sale event it targets, and the offer templates auto-adjust the recommended rate multiplier and lead time based on which of the three you pick. Creators see the sale tag in the offer and factor it into their availability, which cuts the awkward back-and-forth that used to burn a week off the 11.11 booking window. If you are planning your Q4 calendar this month, the first honest question is not how big the boost budget is, it is which single sale your SKU actually belongs to.
