Update every shelf price in seconds-automatically, accurately, and without touching a single paper tag.
- Electronic shelf labels (ESLs) replace printed price tags
- Sync directly with your POS or pricing system
- Update instantly when prices change
- No printing, no manual swaps, no lag
For retailers managing hundreds or thousands of SKUs, that shift from manual to automated pricing changes everything: fewer errors, faster promotions, and store teams free to focus on customers instead of tag changes.
What Are Electronic Shelf Labels?
Electronic shelf labels are digital price displays mounted at the shelf edge and allow you to:
- Automatically update prices, promos, and product info from a central system
- Eliminate printing, distributing, and replacing paper tags
- Keep shelf prices synced with your POS
- Reduce errors, compliance risk, and manual labor
The result is a shelf that always matches your POS: an electronic shelf labeling system that eliminates discrepancies, reduces compliance risk, and cuts manual tag-change labor.
Inside the ESL System: Labels, Network, and Software
The Labels
Digital shelf-edge displays in multiple sizes and formats. Each label uses e-paper or similar low-power display technology, giving it years of battery life without replacement. Labels are mounted on standard shelf rails, peg hooks, freezer doors, or specialty fixtures.
The Communication Network
Infrastructure installed throughout the store that transmits pricing updates to individual labels. MarginMate’s system uses Zero Wireless Bandwidth technology – bi-directional diffused infrared – meaning updates never compete with your store Wi-Fi, POS terminals, or customer devices.
The Management Software
The platform that connects your POS, ERP, or pricing system to every label in every store. It handles integrations, manages label templates, schedules promotions, and provides a centralized view of pricing status across all locations. All updates are centrally managed and available for both cloud and on-premises configurations.
How Pricing Updates Reach the Shelf
After setup, Electronic shelf labels (ESLs) need little to no store-team effort:
- Price changes start in your POS, ERP, or pricing system
- The ESL platform receives updates automatically
- Correct labels refresh in seconds
- No manual steps, no printing, no overnight delays
- Shelf prices stay synced with your POS
No manual steps. No printing queue. No waiting for an overnight update window.
Electronic Shelf Labeling for Prices, Promos, and Compliance
ESLs do more than display a price. A well-configured electronic shelf labeling system turns every shelf edge into a live communication channel between your pricing system and your shoppers.
What you can display and manage:
- Regular and promotional pricing – switch instantly between the everyday price and promo price without touching the shelf
- Unit pricing and compliance fields – display per-unit price, weight, or volume to meet shelf-labeling regulations
- Barcodes and product identifiers – scannable barcodes on the label itself for faster stock management
- Staff-facing back pages – additional label pages accessible via handheld IR key for stock quantity, replenishment flags, and internal product info
- SmartFLASH LED – flash individual labels in under one second to guide staff to the right shelf location for click-and-collect, put-to-light replenishment, or shopper pick lists
- Planogram-aware display – configure templates by department or category so labels match your merchandising format automatically
Display Formats and Shelf-Edge Options
Electronic shelf labels (ESLs) are not one-size-fits-all:
- The right format depends on your shelving, product category, and display needs
- MarginMate supports multiple label sizes, from compact shelf-edge formats to larger displays
- Suitable for peg hooks, shelf rails, display cases, freezer doors, slatwall, and specialty fixtures
- Designed for retail environments, including grocery, hardware, liquor, and furniture
- High-contrast displays stay easy to read at normal browsing distance in bright or low-light settings
Installation, Setup, and Ongoing Management
The most common reason ESL projects underperform is poor deployment planning, not the technology itself. Retailers who run into problems typically encounter issues in three areas: incomplete POS integration, inadequate store infrastructure coverage, or systems that overload the store network.
MarginMate’s deployment approach is designed around avoiding all three.
What We Handle
- Infrastructure planning and store layout assessment
- POS, ERP, and pricing system integration

What Our Clients Are Saying
Retailers choose MarginMate for its reliability, performance, and ability to deliver accurate pricing across complex retail environments.
I feel pretty good about it. It isn’t nearly as complicated as I thought it was going to be, and it went in pretty painlessly. It’s very easy to use, and we just haven’t had any problems. One of the biggest benefits for us is that it saves us from having to print and put out shelf tags every semester, so it’s a lot more efficient. Everybody’s been really impressed, and we’re excited to use it.
David Brown
It’s a great system, way better than our old system. We’re able to keep things updated on the fly with just a click away, and it helps a lot with inventory. I’d recommend it – installation was simple, a one-day thing, and it was easy.
Carlo
Really excited about this system. I’d been asking for it for about two years, and it’s been great so far. It was easy to do, easy to install, and easy to work through, and the staff on-site were great and very helpful. The biggest benefit for us is customer service – being able to see real-time stock and pricing updated quickly, keep data up to date, and change what we display to the customer. It’s fun, but more importantly, it’s extremely useful.

| Capability | ESL System | Paper Labels |
|---|---|---|
| Price update speed | Seconds, store-wide | Hours, tag by tag |
| Shelf-to-POS accuracy | Always synchronized | Prone to human error |
| Promotion execution | Instant across all locations | Manual, slow to execute |
| Labor requirement | Minimal after deployment | Recurring, weekly effort |
| Multi-store control | Centralized platform | Store-by-store process |

Frequently Asked Questions
What is an ESL system?
An ESL system is the combination of three components: the electronic shelf labels themselves, a store communication network that transmits updates to those labels, and management software that connects to your POS or pricing system. Together, they allow price and product information to update automatically across every shelf in the store.
How do electronic shelf labels get updated?
Updates are triggered in your existing POS, ERP, or pricing system – no change to your current workflow. The ESL platform receives those updates through an integration or scheduled pricing file, identifies the affected labels, and transmits new pricing through the store infrastructure. Each label refreshes its display automatically, typically within seconds.
