This post shows how to deploy a multimodal WhatsApp ordering assistant built with Amazon Bedrock AgentCore and Amazon Nova 2. Many quick-service restaurants spread ordering across an app, a website, a phone line, and the counter. Each of those is a separate system to build and run. Each one also fragments the customer’s history, making the same person look like a stranger on every channel. Customers already live in their messaging apps. WhatsApp reaches more than two billion people.

At many restaurants, a large share of orders still arrive by phone, and those calls usually land on a staff member who is already taking care of customers at the counter. Callers wait on hold, orders get written down by hand, and busy periods make both worse. Adding an app or a website helps customers who prefer to order online, but it does nothing for the person who wants to call and order.

Restaurants miss an average of 150 phone calls per location every month, and about 60 percent of those are customers trying to place an order or book a table. Most of these calls come in during dinner service, exactly when the host is seating guests, servers are turning tables, and the phone becomes an afterthought. Pulling someone off the floor to answer doesn’t fix the problem. It only makes two experiences worse.
