A restaurant's AI phone ordering added $8K in sales in a month
In plain words
After tuning menu recognition and running test orders, a restaurant let an AI take phone orders straight into its system.
What happened: About $20K in phone-order revenue in a month, roughly $8K above before (their own figures)
These numbers come from the builder and haven't been checked independently.

How to do it yourself
Our suggested steps. The company didn't publish theirs.
- 1
Count how many calls ring out at peak times.
- 2
Load your full menu with prices, modifiers and items people mispronounce.
- 3
Connect the agent to your POS or ticket printer and paste the prompt.
- 4
Place 30 test orders, including tricky ones.
- 5
Go live at your busiest hour and review orders daily.
The instructions to give the AI
Paste this into your AI tool (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.
Agent instructions (prompt)
You take phone orders for [restaurant]. Use only items and prices on this menu: [menu]. Confirm size, extras and pickup or delivery. Upsell one drink or side once. Read the full order and total back before confirming. If unsure about an item, transfer to staff.
[Highlighted] = replace with your own details before you run it.
What you should get back: A clean ticket in the kitchen: "2x Margherita (large), 1x garlic bread, pickup 6:45pm, $38.50."

Possible if you are comfortable wiring tools together and testing for a week or two. If not, hire a builder: most owners do.
