Part 1 The problemWhy teams need this

01 · THE PROBLEM

A voice agent that answers 24/7 is only worth it if what the caller said reaches the person who calls them back. This is that handoff. The call ends, and a structured lead appears.

Part 2 How it worksWhat it does, step by step

02 · WHAT IT DOES

When a call with your voice agent ends, the workflow picks up the call analysis and pulls out what an agent needs: property type, budget, preferred area and whether they want an appointment. It files it in Airtable with the summary and transcript, ready for follow-up.

03 · HOW IT RUNS

Step by step, as built.

  1. Take the right event

    Retell sends several events per call; only the finished analysis is processed.

  2. Structure the call

    The fields that matter for a property enquiry are pulled out of the analysis.

  3. Create the record

    One Airtable row per call, ready for the agent's follow-up.

05 · WHEN SOMETHING BREAKS

Failure is designed in.

  • 1decision point (IF or Switch) checks the data before it moves on.

Standard on every build

  • Schema validation before downstream writes
  • Retry and error routes for external API failures
  • Duplicate-safe processing and idempotent updates
  • Human approval where the action carries business risk
  • Execution logging for support and audit review

Part 3 The impactWhat it's worth, and how we'd build yours

Projections for a typical deployment. The calculation below shows the math, and you can put in your own numbers.

07 · ROI CALCULATION

How it pays back in your business.

The starting numbers are a hypothetical deployment sized to the projections above. Change any of them to your own volumes and costs, and the math updates underneath.

The math: 300 calls logged × 8 min × 12 months × 90% ÷ 60 = 432 hours a year × $40/hour = $17,280. Net value = gross value − $240 running cost a year.

08 · HOW WE'D BUILD YOURS

How we'd build yours.

  1. Discover: map the current process, systems, volumes, owners and exceptions.
  2. Design: define the canonical data model, approvals, retries and system boundaries.
  3. Build: implement credentials, nodes, validation and observable error routes.
  4. Prove: run controlled data through success, duplicate and failure scenarios.
  5. Operate: publish runbooks, ownership and measurable service levels.

SAME SYSTEM

Smaller jobs, done properly.

One-purpose workflows: a single unsubscribe endpoint for every list we send from, and a voice-agent build that turns a phone call into a structured record.
