Handle restaurant orders from Retell.ai phone calls using Make

Hey Make community,

This is a workflow that handles restaurant orders with Retell ai. The scenario gets the order data and creates a PDF of the order, including all items on it.

Step1:

  • Get order data and order items from a custom function on Retell AI
    Modules 26,25,19.

Step 2:

  • From all items, calculate the subtotal. This is used to audit AI total calculations.
    Modules: 19,61,60

Step 3:

  • Create an invoice document as a Google sheet and then add order items line by line. We used a specific template on a Google Sheet.
    Module: 49,27,50,62

Step 4:

  • Convert the order into a PDF so it can be used for SMS, Fax, or email delivery.
    Modules 54, 55, 63

Step 5: Important for the next day or running

  • We save all data into a master Google Sheet where we run audits to find where the model fails and which are those opportunities for improvement
    Module: 32, 37

I have done the work on Make, and a huge effort came from the client on improving the Retell AI instructions. Those instructions make a lot of sense on the model’s performance.

How do you guys handle orders and order items from phone calls coming from ai voice services?
