Dark Stores for Grocery Retailers: What Are They and How Do They Work?

Online grocery shopping is booming, and it is here to stay. In the U.S. alone, online grocery shopping reached nearly $90 billion in sales in 2020, an increase of more than $30 billion. The same research tells us that online grocery shopping will push past $100 billion in 2021. By 2023, it will make up 11.2% of total grocery sales in the United States. 

Many grocery retailers are now trying to meet increased demand for online delivery. They are expanding their omni-channel capabilities for online ordering and refining their storage and distribution processes. Today the challenge is: How can grocers provide great experiences all the way to each customer’ doorstep?

It all comes down to delivery and the answer lies in ‘Dark Stores’.

What is a Dark Store?

A Dark Store -also known as micro-fulfillment center- is a location dedicated to rapid online order fulfillment. It is a small, local store but without the customers. Just like any other conventional grocery store, a Dark Store has aisles with shelving and racks for groceries.

When a customer order comes in, Dark Store employees pick and pack the items immediately. Then they either ship the order direct to the customer’s address or to a convenient collection point specified by the customer.

What are the challenges of running Dark Stores from an inventory planning perspective?

Delivery is now the cornerstone of the customer experience. Grocers are offering super speedy deliveries that can get groceries to their customers’ doors the same day or even within hours or minutes. To keep their pledge of instant shipments, retailers need to build up a new network of fulfillment and delivery centers.

Even though Dark Stores make fulfilling online orders as simple as possible, they come with a few challenges.

1. Delivering customer service excellence at a low cost

Inventory management is central to delivering cost-effective service excellence. For grocery retailers, being a cost-leader and service-leader at the same time might seem counter-intuitive. However, it’s possible to achieve this with sufficient supply chain visibility and execution.

By positioning inventory efficiently, grocers can maximize their ability to most profitably fulfill their customer demand. They can start winning on ‘customer experience’ by being more predictive when meeting customer demand, providing greater product availability in a more cost-effective manner and offering the best service, pricing and overall experience.

2. Achieving highest forecast accuracy

Accurate demand forecasting is vital for grocery retailers who want to keep up with the customers’ delivery requests. Existing replenishment and forecasting systems with old data structures don’t provide accurate, granular forecasting that separate online orders from in-store demand. They fail at making the most profitable replenishment decisions for stores and dark stores that fulfill the demand streams.

Unlike traditional forecasting data structures, Dark Store forecasting needs to generate highly accurate forecasts by making use of the online channel data as well as taking promotional events, local demand and competition into account.

By creating accurate short-term baseline forecasts at the SKU / zipcode / day / fulfillment preference level and forecasting demand at each location, grocers can position their inventory at the right amount at each location so that they can successfully increase your order fulfilment performance.

3. Overcoming the perishables challenge

A typical grocery order can consist of both perishable and non-perishable items. And majority of grocery items such as dairy, meat, fruits and vegetables have a short expiry window. If the product is not fresh, it’ll result in an unpleasant customer experience.

The challenge is to make sure that every perishable item is delivered to the customer’s doorstep in its prime form. Yet, this can easily become a burdensome process for a grocery retailer.

Using Dark Stores to store and manage perishable item is a great way to overcome this challenge. Once grocers have enough space, visibility for pickers and flawless inventory management capabilities in their Dark Stores, they can maintain the ideal freshness level for perishable items and minimize the time between off-the-store-fridge to delivery.

What are the benefits of using Dark Stores?

Aside from being ideally located for fast delivery operations in high order-density zones, Dark Stores offer several benefits. They enable grocery retailers to:

  • Improve the efficiency of online picking operations and drive faster profitability in their online business
  • Become more efficient by picking online orders in a space that doesn’t have customer traffic
  • Manage inventory more effectively
  • Do multiple replenishments in a day and get the planning cycles can be down to hours
  • Service new customers who are far away from an existing store and where they don’t have the opportunity to open a physical store.
