Electronic shelf label buyer's guide: the reading order

To evaluate electronic shelf labels without getting lost, read in this order: what you are buying and how a price travels to the display, what it costs with your own numbers, what to ask each manufacturer, how to run a pilot, and which price-marking rules apply. This page only sets the route; every step has its own article.

The route, step by step

Step	What to read	What you come away with
1. Understand the system	What is an electronic shelf label	The parts you are buying: label, gateway, platform and integration
2. Follow a price change	How electronic shelf labels work	The path from ERP to display, and where it can stall
3. Put numbers on it	How much ESLs cost and the total cost calculator	A multi-year cost built on your assumptions, not the brochure’s
4. Build a shortlist	Manufacturers compared and the vendor checklist	Three or four candidates and the questions that separate similar offers
5. Request proposals	RFP template	Answers you can compare line by line
6. Test in a store	Pilot project	A success criterion written down before the first label goes up
7. Stay compliant	Shelf price rules	What UK rules require of the displayed price

Why cost comes third, not first

Price per label is the first number everyone asks for and the one that says least on its own. Two offers built on the same label can differ in the number of gateways, the yearly platform fee, or whether integration with your ERP is billed separately. If you understand the parts first, you walk into the meeting with your own figure to measure the pitch against. If e-paper is a black box to you, the glossary entry explains why the display draws so little power.

If you do not run a grocery store, look at electronic shelf labels by sector early on: label size, how often prices change and what has to fit on the shelf edge vary a lot between a DIY store and a fashion shop.

Three questions for the first vendor meeting

• Who sends the prices, and who maintains that link? It might be the ERP, the point-of-sale system or a spreadsheet; whoever maintains it gets the call when a price does not arrive.
• What happens to the installed labels if you change platform? In many systems the label only talks to its own manufacturer’s radio. We cover this in vendor lock-in.
• How many gateways does your floor need, and how is that checked? The range a manufacturer publishes is not what you will get between chillers and metal shelving; see how many gateways you need.

After the pilot

The implementation guide covers phases, staff training and retiring paper tickets. When something breaks in production, the most common case is a label that stops updating, which has its own step-by-step diagnosis.

Regulation: last on the list, not optional

The English regulation pages cover UK rules, including was/now and reference pricing and what happens when the till charges more than the shelf. That second case is exactly what a well-integrated label system should make rare, so it is worth reading before you sign, not after.
