Voice-Activated WhatsApp Workflow for Construction Quotes (Screenshot Included)

Hey everyone,
I’m building a voice-activated workflow in Make for construction workers to request plant machinery hire quotes via WhatsApp or voice (phone).

Here’s a screenshot of what I’ve built so far:

What I’d like the workflow to do:

  • Be triggered by a voice or text message sent via WhatsApp (ideally hands-free on site).
  • Automatically extract key information from the message, such as machinery type, location, and hire dates.
  • Generate templated emails and send them to a list of predefined plant hire providers.
  • Include a simple approval step for the project manager (either by replying on WhatsApp or another quick method) to approve before the emails are sent out.
  • Provide a confirmation message back to the original sender once the emails have gone out.
  • I’m also exploring whether something like agentic AI or CrewAI could help make this more dynamic, but I’m not sure where to start or if that’s overkill.

My questions:

  • Am I going about this the right way for this kind of workflow?
  • Is there a better approach to managing the approval step from mobile?
  • Would agentic AI help here, or is Make enough?
  • Any tips for managing email templates per provider dynamically?

Appreciate any advice from folks who’ve done something similar.
