Digital Signage ROI: Measuring What Matters for QSR Operators

A comprehensive guide to digital signage ROI restaurant measurement—from establishing baselines to ongoing optimization.

---

"Is this technology working?"

It's the question every operator asks about significant investments. Digital signage, kiosks, and menu boards represent substantial capital. But measuring their return isn't straightforward.

Revenue goes up after installation. Was it the signage? Or the new menu items? Or the marketing campaign? Or the seasonal trend?

This article provides a framework for measuring digital signage ROI that accounts for attribution challenges while delivering actionable insights.

Why Measurement Is Challenging

Understanding the difficulty helps design better measurement.

Multiple Variables

Restaurant performance is affected by:

• Menu changes
• Marketing campaigns
• Competitor activity
• Seasonal patterns
• Economic conditions
• Weather
• Staffing levels
• And more

Isolating signage impact from other variables is genuinely hard.

Time Lag

Impact unfolds over time:

• Initial adoption curve (staff and customers learning)
• Optimization period (content improvements)
• Steady-state performance

Measuring too early captures only the learning curve.

Intangible Benefits

Some benefits are real but hard to quantify:

• Brand perception improvement
• Customer experience enhancement
• Staff satisfaction with tools
• Future-proofing for new capabilities

These matter, but don't fit simple ROI calculations.

Key Performance Indicators

Track these metrics to understand signage impact.

Revenue Metrics

Average ticket size:

• Compare average transaction value before and after signage
• Control for menu price changes
• Most direct measure of upsell effectiveness

Upsell/cross-sell conversion:

• If tracking specific promotions, measure conversion rates
• A/B test different promotional content
• Compare promoted item sales to baseline

Daypart revenue shifts:

• Did signage promotion of breakfast/late-night affect those periods?
• Compare daypart percentage of total revenue
• Identify if messaging shifts customer behavior

Menu item performance:

• Featured item sales compared to non-featured
• New item launch performance
• Low-performer sales after prominent display

Operational Metrics

Transaction time:

• Average time from order start to completion
• Should decrease with effective kiosk implementation
• Compare by ordering channel

Order accuracy:

• Error rate before vs. after
• Particularly for kiosk orders
• Reduced error = reduced remake cost

Labor cost per transaction:

• Staff required per transaction
• Should decrease if self-service effective
• Factor in training and support costs

Queue length and wait times:

• Customer wait time by daypart
• Balancing throughput vs. experience
• Compare to capacity utilization

Customer Metrics

Satisfaction scores:

• If surveying customers, include signage-related questions
• "Was the menu easy to understand?"
• "Was ordering efficient?"

Return visit frequency:

• Among loyalty program members, track visit frequency
• Compare to pre-signage period
• Control for seasonal patterns

Channel adoption rates:

• Percentage of orders via kiosk vs. counter
• Trend over time
• Indicates customer preference and learning

Complaint reduction:

• Track complaints by category
• Menu confusion complaints
• Wait time complaints
• Compare to baseline

Baseline Establishment

ROI requires comparison. Establish baselines before deployment.

Pre-Deployment Measurement

At minimum, capture:

• Average ticket size by location, daypart, channel
• Transaction time by channel
• Order accuracy rate
• Customer satisfaction scores
• Labor hours per transaction

Capture at least 3-6 months for seasonal patterns.

Control Location Strategy

If deploying to multiple locations:

• Deploy to subset first
• Keep others as control group
• Compare performance between groups
• Roll out to controls once impact is understood

Controls enable cleaner attribution.

Data Hygiene Requirements

Ensure data is reliable:

• Consistent POS coding across locations
• Complete transaction capture
• Accurate time stamps
• Defined categories and metrics

Bad data produces bad ROI calculations.

Timeframe Considerations

Allow adequate time:

• 3+ months post-deployment for stabilization
• 12 months for seasonal comparison
• Ongoing for trend identification

Rushed measurement misses true impact.

Attribution Challenges

Acknowledge and address the difficulty of causation.

Isolating Signage Impact

When revenue increases, what percentage is signage?

Options:

• Control group comparison (cleanest)
• Time-series analysis with other variables controlled
• A/B testing specific content elements
• Management judgment informed by data

Perfect attribution isn't possible; reasonable estimates are.

Seasonal Adjustments

Compare same period year-over-year, not sequential months:

• December vs. previous December
• Q3 vs. previous Q3
• Adjust for known anomalies

Market Condition Considerations

External factors affect results:

• Competitor openings/closings
• Local events and construction
• Economic shifts in the area

Document and account for these when analyzing.

Multi-Variable Analysis

For sophisticated operations:

• Regression analysis identifying contribution of each factor
• Data science approaches
• Third-party analytics services

Complexity should match stakes.

Calculation Frameworks

Standard approaches to quantifying ROI.

Simple ROI

Formula: (Gain from Investment - Cost of Investment) / Cost of Investment

Example:

• Investment: $50,000 (hardware, software, installation)
• Measurable gain (Year 1): $30,000 increased revenue attributable to signage
• ROI: ($30,000 - $50,000) / $50,000 = -40% (first year)

Year 2:

• Additional gain: $35,000
• Total gain: $65,000
• Remaining cost: $0 (already paid)
• Cumulative ROI: ($65,000 - $50,000) / $50,000 = 30%

Payback Period

Question: When will the investment be recovered?

Calculation: Investment / Annual Benefit = Years to Payback

Example:

• $50,000 / $30,000 per year = 1.67 years

Typical ranges:

• Menu board systems: 1-3 years
• Kiosk systems: 2-4 years (depending on labor savings)
• Integrated systems: 2-5 years

Total Cost of Ownership

Don't forget ongoing costs:

Initial costs:

• Hardware
• Software licenses
• Installation
• Training

Annual costs:

• Software subscription
• Content updates
• Maintenance
• Hardware replacement
• Electricity

TCO = Initial + (Annual × Years)

Compare to TCO of alternative (e.g., printed menus).

Ongoing Optimization

ROI isn't static—it improves with optimization.

Using Data to Improve Content

Analytics should drive content decisions:

• Which promotional layouts perform best?
• What daypart content drives most revenue?
• Which items sell better when featured?

Test, learn, improve.

A/B Testing Methodology

Structured testing for continuous improvement:

• Define hypothesis
• Create variant content
• Deploy to subset of locations
• Measure defined metrics
• Implement winner broadly
• Repeat

Every improvement compounds.

Continuous Improvement Culture

Building habits:

• Monthly content performance reviews
• Quarterly ROI calculations
• Annual comprehensive assessment
• Regular optimization sprints

ROI grows with attention.
