The Phone Call That Could Have Been a $47 Order (But Wasn't)
Picture this: A hungry customer calls your restaurant to ask if you offer gluten-free pasta. Your phone staff member — bless their heart — says "yes," gives the price, and hangs up. Order placed. Transaction complete. Everyone moves on with their lives.
Except that customer was feeding a table of four, had a birthday in the group, and would have happily ordered appetizers, dessert, and a bottle of wine if anyone had thought to mention them. Instead, they got a $14 pasta and a dial tone.
This is the quiet tragedy playing out in restaurants everywhere, multiple times a day. Your phone staff are technically doing their job — answering questions, taking orders — but they're leaving serious money on the table with every call. The good news? This is entirely fixable. Upselling over the phone isn't about being pushy or salesy; it's about being genuinely helpful and knowing how to guide a conversation. Here's how to train your team to do exactly that.
Building the Foundation: Scripts, Mindset, and Menu Mastery
Before your staff can upsell anything, they need two things: confidence and knowledge. Most phone upselling failures aren't about laziness — they're about staff who feel awkward pushing extras or genuinely don't know enough about the menu to make smart recommendations. Fix those two problems, and you've already won half the battle.
Treat Every Call Like a Table Interaction
Your best servers don't just recite menu items — they read the guest, ask questions, and make thoughtful suggestions. Your phone staff should do the same. Train them to think of every inbound call not as an order-taking exercise, but as a short, friendly dining consultation. That mental shift alone changes the entire tone of the conversation.
Start by training staff to ask one or two simple discovery questions early in the call: "Is this for a group or just for yourself tonight?" or "Is this a special occasion?" These questions take five seconds and open the door to relevant, natural upsell opportunities. Someone feeding a group of six needs to know about your family-size portions. Someone celebrating an anniversary is a perfect candidate for your dessert add-ons. You'll never know unless you ask.
Build Upsell Scripts That Don't Sound Scripted
Nobody wants to feel like they're talking to a robot reading from a laminated card — ironic, we know, but we'll get to that. The goal is to give your staff a framework, not a word-for-word script. Create a list of natural transition phrases they can use to weave in suggestions:
- "A lot of people who order that also grab our garlic bread — it pairs really well."
- "We actually have a deal tonight where you can add a dessert for just $4 — want me to throw that on?"
- "That's a great choice. Are you all set for drinks, or would you like to add a couple of sodas to the order?"
These don't feel like upsells — they feel like helpful suggestions from someone who actually knows the menu. Because they are. Practice these in team huddles until they feel second nature. Role-play is underutilized in restaurant training, and it works remarkably well for building phone confidence.
Menu Knowledge Is Non-Negotiable
You cannot upsell what you don't understand. Your phone staff should know your top-selling items, your current specials, your highest-margin dishes, and your best pairings. Consider running a brief weekly "menu moment" — five minutes before a shift where a manager highlights one or two items worth pushing. Keep it simple, keep it consistent, and watch your average order value climb.
A Smarter Backup: Let Technology Handle What Humans Miss
Even the best-trained phone staff have bad days, get slammed during the dinner rush, or simply forget to mention the dessert special for the fourteenth time in a row. That's not a failure of character — it's just human nature. This is where having the right technology in your corner makes a meaningful difference.
How Stella Can Support Your Phone and In-Store Upselling
Stella is an AI robot employee and phone receptionist that never forgets to mention the special, never has an off night, and never rushes a customer off the phone because the kitchen is loud. For restaurants, she can answer incoming calls 24/7, walk customers through the menu, highlight current promotions, and recommend add-ons — all in a natural, conversational way. She can also be configured to forward calls to human staff when needed, so your team stays in control while Stella handles the volume.
Beyond the phone, Stella also operates as a physical in-store kiosk, greeting walk-in customers and proactively engaging them about specials and offerings. And with her built-in CRM and conversational intake forms, she can even collect customer information during calls — useful for loyalty tracking, order history, or follow-up marketing. Think of her as the team member who always hits their upsell targets, without needing a performance review.
Turning Good Habits Into Great Results
Training is only as effective as the follow-through. The restaurants that consistently outperform on average order value aren't doing anything magical — they're measuring, reinforcing, and iterating. Here's how to make your new upselling habits stick.
Track the Right Metrics
If you're not measuring average order value per phone call, start now. Most modern POS systems can give you this data, and it's one of the clearest indicators of whether your phone upselling efforts are working. Set a baseline, establish a realistic target, and review it weekly. Even a $3–5 increase in average order value across dozens of daily calls adds up to thousands of dollars per month in additional revenue. That math is hard to argue with.
You can also track upsell conversion rate — how often a staff member successfully adds an item to an order that wasn't initially requested. This takes a bit more effort to log, but even informal tracking (a simple tally sheet by the phone) gives you actionable data. Recognize and reward staff who consistently hit or exceed targets. A small weekly incentive for the highest upsell rate does wonders for motivation.
Make Feedback a Routine, Not a Reprimand
Nobody improves when feedback only comes in the form of a manager saying "you forgot to mention the appetizers again." Build upselling into your regular one-on-ones and team check-ins as a positive, forward-looking conversation. Ask staff what felt natural, what felt awkward, and what customers responded well to. The best upsell techniques often come from your own team — the ones actually having these conversations every day.
Consider doing periodic call reviews if you have the capability to record calls (with appropriate disclosures, of course). Listening back to a call together — not to criticize, but to identify opportunities — is one of the fastest ways to coach phone skills. A two-minute review can teach more than an hour of classroom-style training.
Keep Promotions Fresh and Communicated
One of the most common reasons staff don't upsell specials is simple: they don't know about them. If your marketing team launches a new promotion and your phone staff hears about it three days later, you've already lost revenue. Build a simple internal communication habit — a group chat message, a whiteboard by the phone station, or a brief pre-shift announcement — so your team always knows what's worth mentioning. Current, relevant promotions are the easiest upsells in the book, but only if your staff knows they exist.
Quick Reminder About Stella
Stella is an AI robot employee and phone receptionist built for businesses like yours — handling calls 24/7, upselling naturally, and even greeting customers in-store through her physical kiosk. She runs on a $99/month subscription with no upfront hardware costs, is easy to set up, and doesn't call in sick on a Saturday night. Worth knowing about.
Put the Plan Into Action
The gap between a restaurant that's leaving money on the table and one that consistently maximizes every order isn't talent — it's training, tools, and consistency. Your phone calls are not just a logistics channel; they're a sales channel, and treating them that way is one of the highest-return investments you can make as a restaurant owner.
Start this week with three concrete steps: audit your current average phone order value, run one role-play session with your team using the upsell phrases above, and identify your top three high-margin items worth pushing on every call. From there, build in the measurement habits, keep promotions communicated, and make feedback a regular part of your culture — not a reaction to a bad week.
Your customers are already calling. They're already hungry. In many cases, they're already open to spending a little more — they just need someone on the other end of the phone to give them a good reason. Train your team to be that reason, and the revenue will follow.
