What is Zero-Touch Automation?
Zero-touch automation refers to drive-thru orders that are completed entirely by Voice AI without any human staff involvement in the order-taking process. The guest speaks to the AI, the AI captures the order, confirms it, and submits it to the POS, all without a human touching the transaction. Hi Auto achieves 93%+ zero-touch automation for standard orders, with human backup available only for the remaining edge cases. True zero-touch for every order is an unrealistic goal; the practical objective is maximizing zero-touch rate while ensuring quality coverage of exceptions.
Zero-touch represents the full realization of drive-thru ordering automation.

Zero-Touch vs. Assisted Automation
Definitions
Zero-touch:
- AI handles complete order
- No human intervention
- Full automation achieved
- Staff never involved
Assisted (HITL):
- AI handles most of order
- Human helps with difficulties
- Seamless handoff
- Quality guaranteed
When Each Applies
Zero-touch succeeds:
- Clear audio
- Standard orders
- Common requests
- Cooperative guests
HITL needed:
- Complex situations
- Unusual requests
- Communication difficulty
- Guest frustration
Performance Comparison
| Metric | Pure Zero-Touch | Hybrid (Zero-Touch + HITL) |
|---|---|---|
| Completion rate | 60-70% | 93%+ |
| Guest experience | Inconsistent | Consistently good |
| Edge case handling | Poor | Good |
| Operational viability | Limited | Proven |
Hybrid approaches achieve higher effective zero-touch through quality fallback.

Zero-Touch Rate Metrics
Calculating Zero-Touch Rate
Zero-Touch Rate = (Orders without intervention / Total orders) × 100Benchmarks
| Performance Level | Rate | Assessment |
|---|---|---|
| Low | <70% | Operationally challenging |
| Moderate | 70-85% | Some benefit, significant intervention |
| Good | 85-92% | Meaningful automation |
| Excellent | 93%+ | Enterprise-grade performance |
Hi Auto achieves 93%+ at scale.
What Reduces Zero-Touch Rate
Environmental:
- High noise levels
- Poor audio quality
- Equipment issues
- Weather conditions
Conversational:
- Complex orders
- Unusual requests
- Non-native speakers
- Multiple speakers
Operational:
- Menu mismatches
- System issues
- Integration problems
- Configuration gaps
The 100% Zero-Touch Question
Why 100% is Unrealistic
Edge cases exist:
- Unusual requests
- Angry customers
- Technical failures
- Truly ambiguous situations
Forcing 100%:
- Frustrates guests in edge cases
- Damages brand perception
- Creates operational problems
- Worse than having humans
The Right Target
Optimize for:
- High zero-touch rate (93%+)
- Quality handling of exceptions
- Good guest experience always
- Operational viability
Not for:
- 100% at all costs
- Forcing AI on unsuitable orders
- Ignoring guest frustration
- Appearance over reality
Zero-Touch Economics
Labor Savings Calculation
Per-store daily savings:
Zero-touch hours = Orders × Zero-touch rate × Avg order time
= 500 × 93% × 1.5 min
= 697.5 minutes = 11.6 hours equivalent
Actual savings = 3-8 hours (accounting for monitoring, etc.)
ROI Framework
Value delivered:
- Labor hours saved
- Upsell revenue gained
- Accuracy improvement
- Consistency value
Investment required:
- Technology cost
- Integration effort
- Training time
- Ongoing fees
Typical payback: 6-12 months.

- Frustrating edge cases
- Technology prominent when failing
- Guest experience sacrificed
Common Misconceptions About Zero-Touch Automation
Misconception: “Zero-touch should be 100%.”
Reality: Targeting 100% zero-touch forces AI on situations it can’t handle well, frustrating guests and damaging brand perception. The goal is maximizing zero-touch while maintaining quality experience. 93%+ with good fallback beats 100% forced automation.
Misconception: “Zero-touch means no humans needed.”
Reality: Zero-touch automation still requires human oversight, HITL backup, maintenance, and management. The humans shift from order-taking to higher-value activities. Zero-touch changes the human role, not eliminates it.
Misconception: “Zero-touch is all or nothing.”
Reality: Zero-touch rate is a spectrum. Moving from 60% to 80% to 93% each delivers incremental value. Improvement is continuous, not binary. Any increase in zero-touch rate provides benefits.
Misconception: “Guests prefer talking to humans.”
Reality: Many guests prefer fast, efficient AI interaction over potentially slow or inconsistent human interaction. Preference varies by person and situation. Well-implemented zero-touch often scores higher than human alternatives on satisfaction.
