Modern consumers see brands as a unified, continuous experience. Omnichannel retail integrates these diverse touchpoints to ensure that whether a customer is scrolling on social media, browsing on a laptop, or walking down a physical aisle, their journey remains seamless. Read on to learn how omnichannel can unify your customer experience. 

 

What is Omnichannel Retail?

What is Omnichannel in Retail: Explanation and Benefits

Omnichannel retail is a lead-generation and user-experience strategy where a business provides customers with access to its products, offers, and support services across all channels. 

 

Unlike multichannel retailing, which simply involves selling on various platforms, omnichannel retailing focuses on the interconnectivity of those platforms. 

 

In a true omnichannel environment, a customer can start their research on a mobile device, add an item to their cart via a laptop, and ultimately pick up the purchase at a local brick-and-mortar store. Every piece of data, from inventory levels to customer preferences, flows freely between systems to create a unified brand presence. 

Omnichannel Retail Components 

Four foundational pillars should work interconnectedly for a successful omnichannel strategy:

 

Omnichannel journey from CDP and OMS to marketing, store optimization, and checkout

 

 

Unified Data Layer

At the heart of omnichannel is data integration. Retailers use a Centralized Customer Data Platform (CDP) to consolidate cross-channel interactions into a single profile. 

Within this system: 

    • Customer profiles are shared, including online browsing history, app interactions, past in-store purchases, and loyalty program tiers, which are instantly accessible at any touchpoint. 
  • The pricing stays consistent. The promotion data syncs in real-time, preventing issues where a product is priced differently on the mobile app versus the physical store without a current online offer in place. 

Distributed Order Management System (OMS)

An advanced OMS coordinates between separate warehouses, online fulfillment centers, and physical stores. This system includes coordinating fulfillment methods such as: 

  • BOPI/ ROPIS: Buy Online, Pick Up in Store or Reserve Online, Pick Up in-Store. 
  • Allows for shipping from the store, leveraging the physical storefront as a localized distribution hub. 
  • Enables in-store sales associates to order out-of-stock items directly from the warehouse or another store location. 

Cross-Channel Marketing Precision

Applying omnichannel marketing practices to retail aligns your brand messaging with the consumer’s context, without falling into generic ad repetition. To achieve this result, you need:

Optimized Physical Store

Physical stores in this model serve as more than simple transaction points. These digitally-enabled physical storefronts are equipped with:

  • Mobile Point of Sale (mPOS). Store associates are equipped with tablets to look up real-time inventory, view a customer’s digital wishlist, and process checkouts directly at the showroom. 
  • Location-based Technologies. Deploying geofencing and Bluetooth beacons to deliver personalized mobile app notifications or exclusive offers to shoppers the moment they step through the doors. 

Why is Omnichannel Important in Retail? 

Today’s shopper expects “buy online, pick up in-store” and “buy in-store, ship to home” options as standard features. They also expect their loyalty points to be available regardless of where they shop. 

 

Retailers that provide a frictionless journey capture more market share. If a customer encounters a stockout in-store but can immediately order that item via a digital kiosk for home delivery, the sale is saved. 

 

Also, omnichannel systems help consolidate data between web and physical sales, giving retailers a 360-degree view of the customer, allowing for more accurate forecasting and marketing. 

How does Omnichannel Work in Retail? 

Omnichannel retail works by creating a unified message that follows a customer across different platforms. It adapts the message to the customer’s current stage in the journey. 

 

To work omnichannel advertising effectively, a Customer Data Platform aggregates data from every touchpoint. Once data is centralized, retailers use strategic ad retargeting to nudge customers back toward a purchase. 

 

One of the most powerful aspects of modern retail is inventory-led advertising. By linking live inventory feeds to ad platforms, retailers only spend money promoting products that are actually available. This prevents the friction of a customer clicking on an item and finding that the item is sold out.

How to Build an Omnichannel Retail Strategy

Building an effective strategy requires a “customer-first” rather than “channel-first” mindset. Here are a few key steps: 

 

  1. Identify every possible touchpoint and map the customer journey.
  2. Ensure your point of sale, ERP, and e-commerce platforms communicate in real-time.
  3. Prioritize mobile. It is used for research, price comparisons, and digital payments. 
  4. Give floor staff tablets to access customer profiles and online inventory.

Omnichannel Retail Examples

 

Operating in Thailand’s highly competitive banking sector, Krungthai Bank (KTV) aimed to differentiate itself in the digital investment space. Partnering with Perion, KTB sought to deploy a high-impact omnichannel campaign focused on corporate value creation, using advanced technology to deliver relevant financial solutions with high engagement, strong viewability, and measurable brand impact. 

 

KTB executed a data-driven, unified strategy that paired programmatic DOOH advertising with mobile activation. Working alongside Perion and using mobile activation through Locala, the campaign leveraged impression-based delivery and seamless DOOH-to-mobile retargeting. 

The campaign successfully drove performance, visibility, and positive consumer perception. It achieved a 1.43% overall CTR, an 83% viewability rate, and a 40% uplift in positive brand image. 

 

When is Omnichannel Advertising Used in Retail?

Omnichannel is especially useful for the following scenarios: 

 

  1. When you need to drive foot traffic. Use geofencing to send a mobile coupon when a customer is within a certain radius of a physical store. 
  2. To recover lost sales. Sending a personalized email or SMS when a customer abandons a cart, followed by a social media ad offering a small discount. 
  3. To identify key micro moments, the “I want to buy” moments through search intent, and provide immediate, relevant solutions via Perion search publishers’ solutions. 
  4. Omnichannel is useful in cross-selling strategies by using past purchase data to suggest complementary products. 

Omnichannel vs. Multichannel Advertising in Retail

While both terms are used interchangeably, the omnichannel and multichannel strategies differ in focus, process, data, and inventory. 

 

Feature Multichannel Omnichannel
Focus Product-centric; maximizing reach on each channel. Customer-centric; maximizing the experience.
Consistency Varying messages across platforms. Unified brand story across all platforms.
Data Siloed data (online vs. offline). Integrated data (CDP-driven).
Inventory Separate stock for web and store. Unified inventory view.
Friction High channels don’t “talk” to each other. Low; seamless transition between channels.

 

Benefits of Using an Omnichannel Strategy in Retail

Omnichannel strategies increase the customer lifetime value. Shoppers who interact with a brand across multiple channels spend more per transaction and remain loyal for longer periods. 

It also enhances operational efficiency because when inventory is unified, retailers can fulfill orders from physical store shelves. This reduces shipping times and costs. 

 

Moreover, omnichannel allows retailers to understand why a customer buys, increasing personalization. Friction is the enemy of retail. Whether it’s a complicated return process or a website that doesn’t show in-store availability, friction kills sales. Omnichannel removes these hurdles.
