The 12.12 All Out Sale is one of Lazada’s biggest year-end campaigns and to ensure the platform runs smoothly under heavy traffic, Lazada will temporarily freeze and downgrade certain Seller Center features.

If you're participating in 12.12, it’s important to understand exactly which tools will be locked, when the freeze starts, and what you should prepare before the downtime. This article breaks everything down clearly to help you avoid last-minute issues.
 

Why the System Freeze Happens

During mega campaigns like 12.12, millions of users browse, add to cart, check out, and claim promotions at the same time.

To keep the platform stable for both buyers and sellers, Lazada temporarily restricts editing access to high-impact features such as product prices and seller promotions.

This ensures:

• No accidental price changes mid-campaign

• No promo conflicts

• Stable backend performance

• Smoother shopping experience for customers

System Freeze Period (Malaysia)

11 Dec 2025 (8:00 PM) – 14 Dec 2025

During this period, some features in the Lazada Seller Center (ASC) and Global Selling Platform (GSP) will be temporarily locked. Sellers can still view information, but cannot submit, edit, or withdraw products or promotions, nor accept deals.

Features Temporarily Locked During 12.12

1. Price Lock (Campaign-Approved Products)

7 Dec, 12:00 AM – 14 Dec, 11:59 PM

All products approved for 12.12 campaigns will have their prices locked. This prevents sellers from:

• Editing prices

• Changing SKUs

• Modifying campaign-related details

2. Seller Promo Tools

Includes:

• Seller Voucher

• Flexi Combo

• Seller Free Shipping

• Add-On Deals

• Other Seller Promo mechanisms

There will be two freeze windows:

11 Dec, 7:30 PM – 8:30 PM

Short downtime before the main sale push.

11 Dec, 11:30 PM – 12 Dec, 12:30 AM

Freeze continues just before and during the 12.12 midnight launch.

During these times, sellers cannot:

• Create new vouchers or combos

• Edit existing promotions

• Activate/deactivate tools

• Adjust free shipping settings

Tip: If you need last-minute promo adjustments, do it before 7:30 PM on 11 December.

What Lazada Sellers Should Do Before the Freeze

1. Finalise all campaign prices early

Especially if your products are already approved for 12.12.

2. Set up all Vouchers, Flexi Combo, and Free Shipping before 11 Dec

Avoid rushing right before 12.12 midnight.

3. Double-check your Deal & Promotion calendar

Ensure no overlapping promos that may cause rejection or freezes.

4. Prepare inventory and boost ready-to-ship items

A smooth campaign isn’t just about promotions, fulfillment matters too.

5. Download necessary reports in advance

Sales, inventory, or performance reports may be slower during peak periods.

What Lazada Sellers Can Still Do During the Freeze

Even though editing is disabled, sellers can still:

• View product details

• Monitor performance

• Track orders

• Manage customer chats

• Handle fulfilment

Normal operations resume after 14 December 11:59 PM.
