The biggest mistake when choosing electronic shelf labels? Treating them as simple price tags. Modern ESL systems have become a cornerstone of store digitalization and a platform for further retail process automation – from price management to Pick-by-Light and inventory tracking.
Over the past few years, electronic shelf labels have become one of the most important technologies in modern retail. Once reserved primarily for large retail chains, they are now increasingly being adopted by pharmacies, drugstores, electronics retailers, DIY stores, and specialty retailers.
The reason is simple: prices change faster than ever before, customers expect accurate and up-to-date information, and retailers face constant pressure to improve operational efficiency. Manually replacing paper price tags across hundreds or even thousands of SKUs is no longer economically viable.
Yet many businesses make the same mistake when selecting an electronic shelf label system – they focus solely on the hardware cost while overlooking factors that have a far greater impact on return on investment. In this article, we’ll explore the key criteria that truly matter when choosing an ESL solution.
Electronic Shelf Labels (ESL) are digital displays mounted directly on store shelves and connected to business systems. They enable the automatic updating of prices, promotional information, and other product data without the need to manually replace paper labels.
Businesses most commonly implement ESL solutions to achieve:
Selecting electronic shelf labels is about far more than display design or hardware cost. It is a strategic decision that can influence operational efficiency, pricing accuracy, automation capabilities, and the long-term growth of your retail business.
So, what should retailers look for when evaluating an ESL system? How can you ensure your investment becomes a true digitalization platform rather than simply an electronic replacement for paper price tags?
Here are the seven key criteria that should guide your decision.
This is the most common — and often the most expensive — mistake retailers make. Hardware costs represent only a portion of the total investment and, in some projects, account for less than half of the overall cost.
A far more important metric is the Total Cost of Ownership (TCO) over the entire lifespan of the system, typically 7–10 years. TCO includes software licensing and maintenance fees, integration costs, the complexity and duration of ESL implementation, internal resources required for system management, and the costs associated with expanding the solution to new store locations.
A lower-priced ESL solution with high service fees and complex administration can ultimately cost significantly more over five years than a premium solution with lower operating and maintenance costs.
Modern retail environments manage thousands of products and run frequent promotional campaigns. As a result, the ability to update prices quickly across an entire store has become a critical capability.
Imagine your marketing team launches a weekend promotion covering 500 products. A modern ESL system can update all shelf labels within minutes. If the process takes hours, retailers may face pricing discrepancies between the system and shelf labels, customer complaints, delayed campaign rollouts, and additional workload for store staff.
When evaluating an ESL solution, always verify how many labels the system can update per minute and how its performance is affected when a large number of products need to be updated simultaneously.
The true value of an Electronic Shelf Label (ESL) system is realized only when it is fully integrated with the other systems used across the business. Without proper integration, employees still need to perform many updates manually, and much of the expected efficiency gains remain unrealized.
Modern ESL solutions should seamlessly connect with ERP systems, point-of-sale (POS) systems, inventory management software, e-commerce platforms, and marketing tools. The greatest value is achieved when ESL technology becomes an integral part of the existing digital ecosystem. In such environments, a price change made in the ERP system is automatically reflected on the shelf, at the checkout, and in the online store — without any manual intervention.
Before selecting a vendor, always assess the available integration capabilities and verify whether the provider has experience working with the specific systems already used within your organization.
Most businesses evaluate an ESL system based on their current situation: a single store, a specific number of products, and existing operational processes. However, a sound investment decision should also take future growth into account.
When selecting an ESL solution, it is important to think beyond today's requirements. You may currently operate one store, but in a few years that could become several locations. Your product assortment may expand, new sales channels may be added, or you may need to centrally manage pricing across an entire store network.
A system that is not designed to scale can eventually leave you with a difficult choice: either limit your growth or invest in a costly migration to a new platform. When evaluating scalability, consider factors such as the maximum number of supported labels, centralized management of multiple locations, ease of onboarding new stores, and the availability of remote device management capabilities.
Electronic shelf labels have evolved far beyond being a digital replacement for paper price tags. Today, they serve as a platform that enables retailers to automate and optimize a wide range of operational processes.
Modern ESL displays can present QR codes with detailed product information, real-time inventory availability, promotional campaigns, loyalty program benefits, and even customer navigation guidance within the store. When combined with other retail technologies, they can also support key operational workflows, including:
It is this integration of ESL technology with broader retail digitalization initiatives — including inventory management, omnichannel strategies, and retail analytics — that transforms electronic shelf labels from a simple operational tool into a strategic business investment.
When discussing electronic shelf labels, the conversation often focuses on employee time savings. While this is certainly a valuable benefit, many retailers gain even greater value from another advantage: the elimination of pricing errors.
Every retailer has encountered situations where the price displayed on the shelf does not match the price charged at checkout. Such discrepancies can erode customer trust, generate complaints, and, in cases of repeated violations, even lead to regulatory penalties.
A properly implemented ESL system ensures that pricing remains consistent across all channels — on the shelf, at the checkout, within the ERP system, and in the online store. This alone can significantly reduce operational risks and improve the customer experience, regardless of the size of the product assortment.
More and more retailers are looking for ways to reduce the environmental impact of their operations while being able to measure and report the results. This is where electronic shelf labels deliver clear and quantifiable benefits.
A store with 5,000 shelf labels that changes prices twice a week can consume hundreds of thousands of paper labels each year. An ESL system eliminates this waste entirely, helping retailers reduce their environmental footprint. Retailers can also track and report these savings as part of their ESG strategy, sustainability initiatives, and customer communications.
The return on investment (ROI) of an ESL system depends on factors such as store size, the frequency of price changes, and labor costs. Most retailers achieve savings from three key areas:
For larger retail environments, the payback period for an electronic shelf label solution typically ranges from 2 to 4 years. The exact ROI will depend on the specific characteristics of your operation. If you would like an estimated ROI assessment for your store, we would be happy to prepare a preliminary calculation.
Beyond technical specifications, the characteristics of the vendor itself play a crucial role in the success of an ESL project. When evaluating potential providers, consider whether they have experience with projects of a similar size and retail environment, the actual availability of technical support after implementation, whether they can provide customer references you can speak with, and what their product development roadmap looks like for the coming years.
An electronic shelf label project is not a one-time hardware purchase. It is a long-term partnership, and the vendor you choose today will continue to influence your store operations for years to come.
A successful electronic shelf label project does not begin with selecting the hardware. It begins with understanding the processes within your store. That is why, when designing ESL solutions, we focus not only on the hardware itself, but also on system integrations, process automation, and long-term operational growth.
