How Double-Digit Sales Events Strain Logistics (and How Shippers Can Prepare For It)
In Asia, there has been a not-so-new trend where the shopping calendar is built around repeating numbers. From 1.1 to 12.12, major e-commerce platforms such as Shopee and Lazada run double-digit sales campaigns almost every month. This trend isn’t limited to online platforms, it extends to offline stores and malls. For the brands and distributors behind these campaigns, it means that peak seasons are no longer a few times a year, it’s an all-year planning challenge.
This article dives deeper into how double-digit sales events came to be, how these campaigns affect logistics operations, what logistics providers do to keep the supply chain moving, and how shippers can prepare well before the next campaign date.
What Are Double-Digit Sales Events?
Double-digit sales events, also commonly known as double-day sales, are shopping campaigns held on dates where the month and day match, such as 10.10, 11.11, and 12.12. Platforms and offline stores tend to leverage these dates to offer discounts, vouchers and special deals, and many also promote faster delivery at little or no extra cost to buyers.
While it’s a sales event that many online and offline retailers participate in, these campaigns are particularly popular for online platforms.
Where This Trend Started
This trend traces back to 11th November, once informally known as Singles’ Day because the four ones resemble four single people. The date began as a student tradition in China in the 1990s, and in 2009, Alibaba – a major e-commerce platform in China – turned it into a shopping event by offering discounts throughout the day. Other platforms and businesses across Southeast Asia then adopted this idea, and it grew into a recurring fixture of the region’s retail calendar.
A Sales Campaign Every Month
Many e-commerce platforms are now running monthly sales campaigns and below is the typical positioning of each month’s campaign.
| Date | Typical Positioning |
| 1.1 | New Year kick-off sales |
| 2.2 – 8.8 | Monthly platform campaigns |
| 9.9 | Major regional campaign, especially on Shopee |
| 10.10 | Pre-11.11 build-up |
| 11.11 | The largest campaign of the year |
| 12.12 | Year-end campaign |
How Big Are These Sales Campaigns?
The numbers below show why brands and logistics teams take these dates seriously:
- China: Third-party data provider Syntun reported that it tracked 1.695 trillion yuan in Gross Merchandise Value (GMV) across the 2025 Double 11 shopping festival (7 October to 11 November).
- Thailand: During Shopee’s 9.9 campaign in 2025, over one million orders were reportedly placed in the first 30 minutes.
- Malaysia: According to Shopee, Shoppers saved more than RM500 million during Shopee’s 9.9 Super Shopping Day, and 1.2 million items shipped within the first 24 hours, according to Shopee.
How Do Double-Digit Sales Events Affect Logistics?
The impact of these campaigns often lasts well beyond the campaign day, because parcels still have to be dispatched, delivered and, in many cases, returned. In 2025, China’s State Post Bureau reported that daily parcel handling peaked at 777 million during the 11.11 period, far above normal daily volumes.
Common pressure points include:
- Extreme Volume Spikes: Inbound and outbound volumes surge within a short window, straining warehouses, transport and sorting capacity at the same time.
- Backlogs at Sorting and Fulfilment Points: Parcels must be scanned and sorted within tight windows. Processing constraints at warehouses and sorting centres can quickly create backlogs.
- Manpower Strain: Some facilities may use automated sorting, storage and retrieval systems, but operations that rely mainly on people for scanning, picking, sorting and dispatch typically hit labour shortages first.
- Cross-Border Complexity: Many products on platforms like Shopee and Lazada come from overseas sellers. Alongside local fulfilment, logistics providers must handle incoming shipments from abroad, where customs clearance and limited freight space add further delay risk.
- Higher Returns and Reverse Logistics Pressure: Time-limited deals encourage impulse buying, and picking or shipping errors during peak periods add to the problem. Providers must handle return intake, consolidate undeliverable parcels, and link returns to Return Merchandise Authorisation (RMA) records so items reach the right client or are handled to their requirements. This work continues long after the campaign ends.
How Do Logistics Providers Keep Supply Chains Moving?
Demand Forecasting and Analytics
Logistics providers analyse historical data and past purchasing trends to help clients stock the right levels months in advance. When stock is already positioned in the destination country, there is less reliance on last-minute shipments from overseas sellers.
This works best when a client’s systems are integrated with the provider’s Warehouse Management System (WMS) before peak season. Shared data gives both sides better visibility of stock, more accurate demand forecasts, and more reliable labour and capacity planning.
Warehouse Automation
Automated Storage and Retrieval Systems (AS/RS) speed up picking and packing while reducing errors and easing manpower constraints, which matter most when order volumes surge.
The benefits of warehouse automation aren’t limited to e-commerce. Technology components, spare parts and other small to medium-sized cargo can be sorted, stored and retrieved faster and more accurately. At Halcon Primo Logistics, we offer warehouse automation solutions to clients in the technology, mining and heavy machinery industries, where precision, speed and visibility matter just as much.
Flexible Labour Scaling
Logistics providers often use an agile resource planning model, bringing in temporary or seasonal workers and scheduling extended shifts so operations still meet Service Level Agreements (SLAs).
Capacity and Carrier Management
When more shipments move through the supply chain at once, air, ocean and road freight all tend to experience bottlenecks, and competition for limited space drives up delays and costs. Because double-digit sales events now recur on a predictable schedule, shippers can forecast demand from previous campaigns and secure carrier space earlier.
This works better when the shipper and logistics provider communicate proactively, which is why planning conversations should start well before the campaign does. Close communication matters even more today, given geopolitical tensions, extreme weather and other disruptions to supply chains.
How Can Shippers Prepare for the Next Campaign?
Preparation is easier when it follows a structured timeline. A practical approach for the major sales campaigns would be:
- 90 Days Out: Review last year’s campaign data, set demand forecasts, and confirm stock levels and inbound schedules. Start WMS or system integration if it isn’t done yet.
- 60 Days Out: Book air, ocean or road freight capacity. Confirm customs documentation and pre-position inventory in the destination market.
- 30 Days Out: Agree on SLAs, labour and shift plans, and escalation contacts with your logistics provider. Run a test of order flow through the warehouse.
- 7 Days Out: Confirm stock counts, check labelling and packaging, and align on daily reporting during the campaign.
- Post-Campaign: Prepare for returns by agreeing intake, inspection and RMA handling in advance. Review performance against forecasts and feed the lessons into the next campaign.
Frequently Asked Questions
What are Double-Digit Sales Events?
These are sales campaigns held on dates where the month and day match, such as 9.9, 10.10, and 11.11, with discounts and special offers across e-commerce platforms and offline stores.
Why do Double-Digit Sales Events Put Pressure on Logistics?
Order volumes rise sharply because these campaigns compress demand into a short window, while warehouse space, labour and freight capacity stay limited. Returns then extend the pressure after the sales campaign has ended.
When Should Shippers Start Preparing?
Ideally about 90 days before the campaign, so there is time to forecast demand, book freight capacity and pre-position inventory.
Can Businesses Reduce Returns During Peak Periods?
Returns from buyers can’t be eliminated, but returns caused by wrong items shipped can be reduced through accurate picking, supported by WMS integration and automated solutions such as AS/RS.
Get Ready for the Next Campaign
With a sales event on the calendar almost every month, the shippers who fare best are the ones who plan early and work closely with their logistics provider. Planning for a big sales campaign?
