What is a Flash Sale?

A flash sale is a time-bound promotional event in which companies offer extraordinary discounts on different products. They use flash sales to attract more customers, so that the company’s revenue can be multiplied in a short period of time. The period of this promotion varies from a day to a couple of weeks, as per the preferences of the company that launches it in the market.

Flash sales usually go live during specific events, like Black Friday, Cyber Monday, New Year’s Eve, and more others. The purpose of this promotion is not to just drive sales, but to get a strong foothold in the market during important sales seasons. They are largely used by ecommerce stores in the USA to attract new customers, however, brick-and-mortar stores also use them to drive revenue quickly.

How Using a Scalable WMS Can Help Your Warehouse to Perform Efficiently During a Flash Sale

Warehouses often struggle to cope with the intensity of orders during the peak sales season. Their strategy to rely on traditional workflows does not work here, as it fails to support the supply chain that often gets bombarded by loads of customer orders. This leads to various problems, in which inventory stockouts are often seen as the biggest contributor to promotions failure.

The key to solving this issue is using a scalable warehouse management system that can automatically improvise things with the evolving scenarios. These WMS solutions are built to scale warehouses under extraordinary conditions, providing administrators peace of mind during the hectic sales season. They can automate everything from inventory to shipping management, allowing warehouses to function effectively to drive more sales and revenue for the company.

Adaptability to Growth

They allow businesses to scale warehouses without bringing widespread changes in the overall system. This helps them to manage complex workflows and respond to the order spikes in busy sales seasons.

Real-time Stock Control

Nowadays, AI-powered WMS systems automatically manage the entire inventory, giving warehouse administrators more ease in monitoring everything from a centralized dashboard.

Integration with Other Systems

Tips to Scale Your Warehouse for Flash Sales

There are various ways with which you can scale your warehouse during promotional seasons to drive sales. We will discuss some of them below, so that you can understand which tips will work best to improve the productivity of your warehouse.

Tips to Scale Your Warehouse for Flash Sales

Focusing on High-Velocity Picking Zones

Businesses should use the hot pick zones strategy to drive more revenue during the flash sales. It is a practice in which they need to first segregate the most selling items, and then place them at precise locations from where final shipping and order fulfillment is relatively easy. By following this method, the picking and packaging time becomes dramatically shorter, resulting in quicker shipping and customer satisfaction.

To make this strategy work, you need to first identify the items that will get more orders from the customers during the flash sales. It is a preemptive approach that allows you to segregate products even before the sale begins. This can be done by looking at historical data or marketing plans related to that product.

Once that is done, you need to create a ‘hot zone’ where these products will be stored. Make sure to pick those areas where packing and shipping is easier, as that will shorten up the travel time. After that, you need to pay attention to inventory slotting, as these products should be placed in a way that makes the picking process quicker. 

Pre-Kitting and Pre-Packaging

Using a pre-kitting and pre-packaging strategy is another great way to make order fulfillment quicker during flash sales. In this strategy, you need to put individual/multiple high-selling products into a single SKU (Stock Keeping Unit) before the sales start. By doing that, you get the benefit to process every order quickly, driving more sales during a specific promotional event.

To start with the pre-kitting strategy, you need to first identify items that are frequently purchased during the flash sales. It could either be a single product, or multiple items that usually get the most orders.

Once that is done, you need to put them in a single package and create a unique SKU for every order. This helps to make the inventory simple, allowing warehouse administrators to monitor everything quickly. By having all the boxes taped and ready to ship, managing bulk orders during the peak seasons becomes relatively easy for businesses.

Utilize Cross-Docking Strategy

Utilizing a cross-docking strategy proves beneficial for businesses to manage loads of customer orders during a flash sale. It is a method in which high-selling products are directly moved from inbound suppliers to outbound transport, making the shipping process highly fast and hassle-free. Backed by a powerful WMS, it not only minimizes handling time, but also reduces storage cost, allowing businesses to reap more profits effectively.

To use the cross-docking strategy perfectly, suppliers need to label high-selling items proactively, so that their movement from inbound to outbound trucks becomes easy. Meanwhile, a WMS system will also help warehouse administrators to automate documentation and tracking, so that the chances of errors during high-volume movement can be completely negated.

Identify Bottlenecks Through Stress Testing

Running a mock sale in your warehouse is the best option to evaluate the team response in a high-stress environment. It lets you know about various things that help to refine the management process during flash sales. Firstly, it gives you an idea about how well the team is responding when the order volume is dramatically increased as compared to normal days. It helps you to make quick tweaks in your picking and packing method, so that the time to ship and fulfill orders can be greatly minimized.

Besides that, stress testing also lets you know about the contingency plans that can be used in the wake of extraordinary circumstances. There could be different measures a team could take to manage sudden requests, like an inventory stockout or scanner malfunction in the packing area.

Meanwhile, keep in mind that stress tests perform best when they are executed through a WMS system, as it provides a centralized platform where warehouse administrators can make required data simulations to evaluate the response of the team.

Businesses need to have a post-sale plan to manage the outcome of their campaign. It is often tagged as a ‘post-flash’ plan in which businesses pay attention to various customer queries and returns management. Here are some ways with which this phase can also be managed wisely to scale warehouse operations.

Manage the Returns Proactively

Managing returns after the flash sale ends defines how well a business was prepared from the start. The key to managing this phase effectively is by creating contingency plans that rolls in after the sales season concludes. Make sure the operations are devised in a manner that does not disrupt the normal routine process. A WMS system helps greatly in this regard, because it provides various features to automate returns without halting the normal orders management.

Review Campaign Data to Bring Improvements

After the conclusion of a flash sale, it is important to look into the overall campaign data to evaluate various points. By utilizing a quality WMS system, you can access plenty of insights related to the performance of the whole campaign. This will help you to know where the sales struggled, and what precise obstacles it faced while converting leads.

Based on the data acquired through WMS analytics, you can then take the required actions to address them accordingly. This is important because bringing in improvements will help you to prepare better for the next flash sale that could set new targets and objectives than the previous ones.
