Voice AI has transformed restaurant operations, but until now, operators have been passengers rather than pilots when it comes to automated upselling. That's changing today.

Kea has always offered dynamic upsells where our AI intelligently pairs complementary items based on what customers order. But we're taking this several steps further with an industry first: complete operator control over Voice AI upselling strategies.

This image shows a user interface form for configuring an upsell control feature in a sales or e-commerce system. The form guides the user to select an item from the dropdown 'When below item is added to customer's cart' to trigger an upsell of another item selected in the 'Upsell the below item' dropdown. An example is provided, explaining how adding a Pepperoni Pizza to the cart can trigger an upsell for extras like basil. Custom instructions can be added optionally to personalize the upsell message, as demonstrated with a note suggesting to talk about how tasty the margarita is to pair with the burger. The interface includes buttons for canceling or saving changes and highlights an example of the upsell logic that will be implemented. This is likely used for automating upsell suggestions based on cart contents to increase sales.

Kea’s new AI-powered upsell feature lets brands fully customize the call flow based on the items or menu categories added to the cart.

This launch is part of a larger initiative at Kea to put unprecedented control in operators' hands. More exciting features are coming soon, but let's dive into what makes our upsell controls revolutionary.

The Industry's First Customizable Voice AI Upsell System

No other Voice AI platform offers this level of AI upsell customization. While competitors might handle basic upselling, Kea gives you complete control over what gets offered and when.

How It Works

Our system lets you create sophisticated upsell rules based on your specific business needs:

Item-to-Item Upselling: When a customer orders a burger, suggest your new loaded fries. Category Upselling: Order any sandwich? The AI suggests items from your sides category. Modifier Upselling: Customer orders cheese pizza? Suggest adding pepperoni or extra cheese.

The flexibility extends beyond simple pairings. You can add custom instructions that help the AI present upsells in ways that match your brand voice and maximize conversion. Instead of generic prompts, your AI can use context about seasonal items, popular combinations, or special preparations to create more compelling suggestions with our custom instruction space as seen above.

Setting Up Your Rules

The process is straightforward:

  1. Log into your Kea Account Portal
  2. Navigate to the Upsell Control tab
  3. Select your trigger item or category
  4. Choose what to upsell
  5. Add custom instructions (optional)
  6. Save and watch it work immediately

Upsell Control InterfaceThis level of control has never existed in Voice AI before. You're not just turning upselling on or off; you're strategically designing revenue opportunities based on your unique menu and customer preferences.

The Perfect Employee That Never Forgets

Think about your best team member, the one who remembers to upsell every time. Now imagine they work every shift, never get tired, and maintain that same enthusiasm at 11 PM on a Friday night as they do during a slow Tuesday afternoon.

That's Kea AI with upsell controls.

The Reality of Human Upselling

Even your most dedicated employees face challenges:

  • Rush periods make it easy to skip upselling.
  • New team members need constant training.
  • Consistency varies between shifts and individuals.
  • Energy levels affect performance.

Employees in fast-food chains only attempt to upsell 42% of the time, according to a Bernstein report. This means countless missed revenue opportunities every single day.

Kea AI's Consistent Performance

Our Voice AI delivers:

  • 100% upsell attempt rate on configured items and even unconfigured items with Kea AI’s dynamic upsell rules.

  • Consistent messaging that matches your brand with custom instructions that pair with your brand tone.

  • Perfect timing that doesn't feel pushy.

  • Adaptive language based on customer responses.

Here's what really sets Kea apart: complete self-service control from any device.

The Competition's Approach

Other Voice AI providers require you to:

  • Submit requests through support tickets.
  • Wait for engineering teams to implement changes.
  • Schedule updates during business hours.
  • Coordinate with technical teams for modifications.

The Kea Advantage

Our mobile-optimized portal means you can:

  • Make changes instantly from your phone or tablet.
  • Test new strategies during service to see immediate results.
  • React to inventory changes in real-time.
  • Update seasonal offerings without technical assistance.

Picture this: It's 9 PM on a busy Friday. You just received a shipment of a new dessert and want to start upselling it immediately. With Kea, you pull out your phone, add the upsell rule, and the very next caller hears about your new offering. No emails, no waiting, no missed revenue opportunities.

The Revenue Impact You Can Expect

According to Accenture, upselling can lead to a revenue increase of up to 30%. A drive-thru location generating $75,000 in monthly sales could see an additional $3,750 to $4,500 in revenue through AI-driven upselling alone. We see it first hand where $2.50 on an $18 pizza increases that item order value by 13.8% alone. Leveling up and adding entire sides or items to the cart compounds quickly.

With the restaurant industry projected to reach $1.1 trillion in sales this year, marking a 4% increase, every percentage point of improvement matters. Kea's upsell controls give you the tools to capture your fair share of this growth.
