Digital signage
ROI

This article exists because most "ROI" content for digital signage is either marketing fluff ("3x your revenue!") or vendor PDFs from 2017 that nobody can verify. We've collected actual numbers from 200+ Digisini customers in 2024-2025 across hospitality, retail, clinics, gyms and corporate offices, plus public industry benchmarks (FedEx Office, Mvix, Intel, Niche Display), and we'll walk through what genuinely moves the math.

The TL;DR for the impatient: the largest line items on your ROI calculation are not what you think. Sales lift gets the headlines, but print savings and staff time recovered are the bigger, more reliable numbers — and they show up whether or not your customers buy more. Read the rest if you want to defend the numbers in front of a finance director, a franchise owner, or yourself.

What ROI actually means in digital signage

ROI = (gain − cost) ÷ cost, expressed as a percentage or a payback window. For digital signage in an SMB context, gain comes from four sources, in descending order of reliability:

1. Print savings. Money you'd otherwise spend on reprinting menus, posters, chalkboards, laminated inserts, banners. This is hard cash and shows on your bank statement.
2. Staff time recovered. Hours your team would spend designing, printing, transporting, mounting and replacing physical signage. Less visible but real.
3. Upsell lift. Incremental revenue from items featured on the screen — daily specials, combos, premium upgrades, complementary services. Real but harder to attribute cleanly.
4. Soft benefits. Reduced perceived wait time, improved experience, internal comms reach. Real in clinics and offices but hard to monetise directly.

Most vendor pitches lead with #3 because it's the most exciting. We lead with #1 and #2 because they're the most defensible. If your sales-lift assumption turns out to be optimistic, the deal still works. The reverse is not true.

The 5-step ROI calculation

Here's the methodology we use with every Digisini customer asking "is this going to pay off?". You can do it in 20 minutes with a spreadsheet:

1. Step 1 — Current monthly print spend. Look at the last 12 months of print invoices. Menus, posters, banners, replacement laminates, chalk markers, A-frame inserts, in-store signage. Divide by 12 = monthly print cost.
2. Step 2 — Staff time on physical signage. Estimate hours/month spent designing, printing, installing, removing physical signage. Multiply by your fully-loaded hourly cost (typically 15-25€/hour for hospitality/retail SMBs).
3. Step 3 — Digital signage cost. Software subscription (9-59€/month depending on screen count) + hardware amortized over 36 months (a 300€ TV + 35€ Fire Stick = 9-10€/month equivalent).
4. Step 4 — Direct savings. (Step 1 + Step 2) − Step 3. This is the floor of your monthly benefit.
5. Step 5 — Upsell test (optional). Run a controlled comparison: feature item A on screen for 4 weeks, take it off for 4 weeks, compare sell-through. The delta × your margin is your upsell lift contribution.

Print savings — the bigger hidden number

Most owners underestimate their print spend because it's distributed across many small invoices rather than one big bill. Quick benchmark by venue type (2024-2025 SMB averages, UK/EU):

Staff time — the second hidden number

Even more invisible than print spend. The time it takes a manager or owner to design, print, install and rotate physical signage adds up fast. Below is our 2024 benchmarking from time-tracked Digisini customers transitioning from print to digital:

Aggregating across a typical hospitality SMB, this lands at 8-15 hours/month of staff time recovered. At 18€/hour fully loaded, that's 145-270€/month — often the largest single line item in the ROI calculation.

Upsell lift by sector (real benchmarks)

This is the contested number. Vendor marketing claims 30-40%; reality is more nuanced. Below are the lift numbers we observe in actual Digisini customer cohorts in 2024-2025, cross-referenced with public industry studies where available:

Year-1 numbers for a typical restaurant

Putting it all together for a fictional but representative 50-cover UK gastropub installing one TV at the bar and one at the entrance:

Even if you halve the upsell lift assumption (treating it as 2.5% instead of 5%) and double the software cost (full Business + add-ons), the deal still pays back inside year 1. The math is robust because it's anchored in print savings rather than in fluctuating sales numbers.

ROI by sector — what to expect

Honest ROI test — avoid faking the numbers

The temptation when calculating ROI on a project you've already committed to is to inflate every assumption until the spreadsheet says yes. Three rules to keep yourself honest:

1. Track one metric your business already records. Average ticket from your POS. Conversion rate from your e-commerce. NPS from your existing surveys. Don't invent new KPIs for the project — invented metrics are easier to game.
2. Establish a baseline for 30 days BEFORE installing. Most ROI inflation comes from comparing post-install numbers against unreliable "gut feel" pre-install. Write down the baseline. If you don't write it down, you'll remember it as worse than it was.
3. Run on-screen vs off-screen periods. Feature an item for 4 weeks, take it off for 4 weeks, compare. That's the only way to attribute lift to the screen rather than to seasonality, weather, or competing marketing.

The biggest hidden cost

Not the hardware. Not the software. Not the installation. The biggest hidden cost of digital signage is the staff time required to keep content fresh. A screen that nobody updates becomes invisible to regulars within 4-6 weeks — the human brain filters repeated stimuli, and your customer's brain is no exception.

For the ROI numbers above to materialise, somebody on the team needs to:

• Spend 15-30 minutes per week rotating at least 2-3 pieces of content
• Schedule promotions with explicit start/end dates so they auto-expire
• Review which playlists run when, monthly
• Replace stale photography every 6-8 weeks even if the product hasn't changed

That's 1-2 hours per month, total. Small but non-zero. If nobody on the team will commit to it, downgrade your ROI projection by 40-60% — and seriously consider whether digital signage is the right tool. A static printed sign maintains itself; a digital sign needs an owner.

When the ROI math doesn't work

Measurement checklist — 90-day plan

If you've decided to install and want to measure ROI honestly:

1. Day 0 (pre-install). Record baseline: average ticket last 4 weeks, sales of 5 candidate "featured" items, customer complaints about wait time (if relevant).
2. Days 1-30 (post-install, baseline content). Run your default menu/posters. Track the same metrics. This is your "screen installed but no active promotion" baseline.
3. Days 31-60 (featured item A). Pick one item and feature it heavily for 4 weeks. Track sell-through and contribution to ticket size.
4. Days 61-90 (featured item B + remove A). Switch to a different featured item. Compare lift between A and B periods.
5. Day 90 (review). Compute: print savings (actual invoices), staff hours saved (estimate from team), upsell lift (compare A and B periods). Decide whether to expand, hold, or revert.

If after 90 days your direct savings (print + staff time) already cover the screen cost, the screen is paying for itself. If they don't, look at content rotation discipline before blaming the tool.
