The Challenge
What We Were Solving
A popular restaurant chain with 5 locations was losing 15-20% of phone orders to busy signals and long hold times during peak hours. Each location received 100+ calls daily, and staff couldn't handle food prep and phone orders simultaneously.
- 15-20% of phone calls going unanswered during peak hours (11am-2pm, 5pm-9pm)
- Average hold time of 4+ minutes causing customers to hang up and order from competitors
- Order errors from miscommunication over phone costing $2,000+/month in remakes and refunds
- Staff pulled from food prep and service to answer phones, slowing down in-store operations
- No system for managing reservations — double-bookings and lost reservations were weekly occurrences

Our Solution
What We Built
Natural Voice Ordering
AI voice agent that sounds human, understands accents and background noise, handles menu modifications ("no onions, extra cheese"), and confirms orders back to customers before processing.
Context-Aware Upselling
Smart upsell suggestions based on order composition and time of day. "Your pasta pairs great with our garlic bread — would you like to add it for $3.99?" Increased average order value by 18%.
Reservation Management
Automated table booking with party size handling, wait time estimates, and SMS confirmations. Manages waitlist during peak hours with callback notifications when tables become available.
Dietary Intelligence
Understands and flags dietary restrictions (gluten-free, nut allergies, vegan). Suggests appropriate menu alternatives and adds kitchen alerts for allergy-sensitive orders.
POS Integration
Orders placed via AI are instantly injected into the Square POS system with correct modifiers, pricing, and estimated prep times. Kitchen sees them identically to in-person orders.
Manager Dashboard
Real-time call analytics, order accuracy metrics, peak hour patterns, popular item trends, and staff handoff logs. Automated daily revenue reports per location.

Client Feedback
“We went from missing 20% of our calls to answering every single one. The AI takes orders faster and more accurately than our best phone staff. Our kitchen loves it because the orders come in clean with no miscommunication. Revenue is up 30% and we haven't hired a single new person.”
