# This Open Source Workflow Helps Local Businesses Reclaim Missed Leads

By Matt · Jun 14, 2025

### Missed Calls = Missed Revenue

If you run a small business — or work with one — you know the pain of missed calls. Whether it’s a dentist’s office, a contractor, or a local gym, calls go unanswered all the time. And here’s the real problem:

> 62% of people won’t call back if their first call isn’t answered.

That’s a lot of leads lost to voicemail. But what if you could automatically follow up with those missed callers in real time — no expensive software, no call center needed? That’s exactly what this open-source workflow does. Built on n8n, it gives local businesses a second shot at winning the lead. And yes — you can download it free

### Why Local Businesses Need This

Here’s a real example: A dental clinic in town has two front desk staff. During busy hours, they’re answering questions, booking appointments, and juggling patients. When calls come in and go unanswered — the caller usually moves on to the next practice in Google Maps. It’s not their fault — it’s a system problem. One we can fix with a simple automation.

### What the Workflow Does

1. Listens for missed call events from Twilio (or any VoIP that supports webhooks)
2. Sends an automatic SMS like:

   > “Hi! Sorry we missed your call — we’ll reach out shortly.”

3. Logs the lead in Google Sheets with a timestamp so the team can follow up later

This entire process takes seconds, happens 24/7, and runs without manual input. 📥 Download the Workflow JSON Template

### How It Works (Simple + Powerful)

Here’s the flow inside n8n:

- Webhook Node — Receives incoming data from Twilio when a call is missed
- Set Node — Parses the caller’s number and adds a timestamp
- Twilio Node — Sends the SMS reply
- Google Sheets Node — Logs the number and time to a spreadsheet

No code needed — just plug in your Twilio number and Google Sheets, and you’re ready to go.

### Why You Should Use the Paid n8n Plan (Not Self-Hosted)

Feature | Free Tier | Starter Tier ($20/mo)
--- | --- | ---
Webhook speed | Shared/slow | Dedicated & real-time ✅
Monthly executions | 200 | 5,000+ ✅
Workflow limit | 2 | Unlimited ✅
Intended use | Testing only | Client-ready ✅
Hosting & maintenance | DIY | Managed for you ✅

While n8n is open-source and technically self-hostable, we strongly recommend using the Starter Plan for client work. Why?

- No server setup or maintenance
- More reliable and faster webhooks (critical for SMS timing)
- Peace of mind for non-technical users
- Commercial use is fully supported

If you're building automations for real businesses, the Starter Plan is absolutely worth the $20/month.

### How to Offer This as a Simple Service

You’re not selling software. You’re solving a very common, very expensive problem. Here’s how you can package this for clients:

- ✅ Setup fee ($100–$300) for installation + training
- ✅ Monthly retainer ($20–$100) for support, reporting, or expansion
- ✅ Optional add-ons: CRM sync, email alerts, contact scoring

This works for:

- Dentists
- Contractors
- Home services
- Med spas
- Real estate agents

Anyone who gets leads by phone and loses business when they miss a call.

### Frequently Asked Questions

🤔 Do I need to know how to code to use this? No. The workflow is built in n8n, which uses a visual interface. You just need to copy and paste your Twilio credentials, Google Sheet ID, and connect the steps. We provide a free template to make setup easier.

🤔 Why not just use Zapier or Make.com for this? You could — but you’d pay significantly more per month, especially at scale or across clients. n8n offers more flexibility, control, and hosting options. The $20/month Starter plan covers what Zapier would charge $100+/month for.

🤔 Can I sell this automation to clients? Yes — the n8n Starter plan allows full commercial use. You’re not selling the software — you’re offering a helpful service built with it.

🤔 What do I need to run this?

- A Twilio account (to send/receive SMS)
- A Google Sheet for logging
- An n8n Starter Plan account Optional: a basic website or Notion page to show clients what you offer.

🤔 Will this work with other phone systems? Yes, if the phone system can send webhook events (many VoIP systems can). We used Twilio in our example because it's easy to integrate, but others like Plivo, RingCentral, or even GoHighLevel (with some effort) can be adapted.

🤔 What if I want to add CRM support, email alerts, or more? That’s the beauty of n8n — it’s fully modular. You can add new steps like:

- Emailing a summary to your client
- Adding the lead to Airtable, Notion, or a CRM
- Sending Slack or Discord alerts

You’re only limited by your imagination (and your plan limits).
