Handling Appointment Leads and Follow-up With Twilio, Cal.com and AI
Convert more enquiries into booked appointments without adding headcount. An AI agent qualifies leads over SMS, books slots against live availability, chases quiet prospects and handles reschedules or cancellations on its own.

Common questions
Before you book a call.
Answers to what most teams ask when they look at a workflow like this. If yours is not here, ask us on the call.
Can you build this sales workflow for our team?
Yes. We design and ship workflows like this as part of our AI Sales & Marketing practice. The fastest way to scope it is a 30-minute call — we share what we would build, what it would cost, and how fast it would ship.
What tools does this workflow use?
The default build connects Airtable, Twilio, and AI Agent, plus 5 other integrations. The same pattern works on n8n, Make, or Zapier for simpler runs, or as a custom Node or Python service when reliability and volume justify the build. See Workflow Automation for how we choose the right platform per use case.
What does a build like this typically cost?
Most workflows of this complexity sit inside a Discovery sprint or a small Build engagement rather than a fixed-price product. See our pricing model for how engagements are structured, or book a call and we will scope this specific workflow against your stack.
Have you shipped something like this for clients?
Yes. See our case studies for examples of automation and AI builds we have delivered, including a podcast platform we took from zero to 261K monthly Google impressions in six months on a content + automation engine.
What other Sales workflows can you build?
Plenty. Browse our other Sales workflow ideas for documented patterns, or tell us what you would like to automate — most clients arrive with a problem rather than a specific workflow in mind.
