| Assumption | Our default | Studies show up to | What it means in practice |
|---|---|---|---|
| Staff hours saved | 0.25 hrs per screen/day |
60% reduction in setup time
Centralised digital signage vs. manual print workflows across locations
Lsquared ↗
|
Just 15 minutes per screen — no more walking the floor swapping posters or manually adjusting displays. In a store with 10 screens that's 2.5 hrs saved daily. Note: no published study measures this per-screen per-day; 0.25 hrs is a conservative working assumption. |
| Conversion uplift | 0.5% of transactions |
8.1% average sales lift in retail
Peer-reviewed study: 237 retail campaigns, 30M customer receipts over 4 years. Up to 25% for new product launches. Published in Journal of Marketing, 2026.

Our 0.5% is intentionally far below what peer-reviewed retail studies document — making the business case easy to defend with any finance team. If the customer has their own data showing higher uplift, simply adjust the input. |
| Upsell / cross-sell | 0.3% basket uplift |
72% of shoppers make unplanned purchases
In-store messaging drives unplanned retail purchases; emotional/inspirational digital content adds 11–12% further conversion lift vs. informational content (Journal of Marketing, 2026)

Basket size increases when customers see complementary products at the right moment — a menu board prompting a side dish, a screen at checkout showing a premium add-on. Our 0.3% is modest and finance-team-safe. |
| Print cost eliminated | €2,500 per site/year |
€9,000–€18,000/site/year
Grocery retailers average $10,000–$20,000 per location annually on printed materials alone

Design fees, print runs, shipping, installation labour, and disposal. Customer Input: "How often do you change your promotional materials and who installs them?" Most retail customers spend well above €2,500 once all hidden costs are counted. |
| Energy savings | 15% of legacy fixture cost |
15–80% reduction
Covers all forms of replaced signage: backlit print & poster frames (always-on lighting behind static visuals), illuminated display cases & lightboxes, older 1st-gen digital screens (200–400W) replaced by modern screens (40–100W with brightness scheduling), and other legacy signage such as overhead spotlights or neon used to highlight product areas.

Captures the energy cost of whatever ZetaDisplay screens are replacing — legacy digital displays, backlit posters, illuminated lightboxes, or other in-store signage lighting. Modern digital screens run significantly lower wattage and support automatic brightness scheduling and overnight standby, compounding the saving. 15% is deliberately conservative; customers replacing older fixtures or always-on lighting typically see 40–80% reductions. |
The Benefit Realization Factor is a multiplier applied to every benefit category at once. It answers the question: "What if we don't capture the full benefit?" — and lets you stress-test the investment in real time without changing individual assumptions. This is your most powerful tool in a live customer conversation.
