Case Study: How I Saved 20 Hours/Week (and $40k/yr) by Firing My Voicemail

Updated: February 13, 2026 • Real Business Story

Two years ago, I hit a breaking point. I run a mid-sized plumbing dispatch service. We were growing, which was great, but I was miserable.

Why? The phone never stopped ringing.

If I was on a job, I missed calls. If I was eating dinner with my family, I answered calls (and my wife hated it). If I let it go to voicemail, 80% of people didn't leave a message—they just called the next plumber on Google.

"I calculated that every missed call was costing me roughly $450 in lost revenue. I was bleeding money while working 60-hour weeks."

The Solution: An AI Gatekeeper

I looked into hiring a receptionist. The cost? $40,000 a year plus benefits. For a small business, that's a massive hit to margins.

Then I tried a "Virtual Assistant" call center. It was cheaper ($300/mo), but the quality was awful. They messed up names, double-booked slots, and sounded bored.

Finally, I tested an AI Receptionist (I used Marlie.ai). I was skeptical. I expected a robotic "Please press 1."

Instead, I got a voice that sounded human, understood slang, and could actually look at my Google Calendar and book slots.

The Results (After 30 Days)

20 hrs Time Saved / Week
$5,200 Extra Revenue
0 Dinners Interrupted

How it works in practice

  1. The Call Comes In: If I don't pick up after 3 rings, the AI answers. "Thanks for calling Mike's Plumbing, this is Sarah. How can I help?"
  2. Filtering: If it's a spammer ("We've been trying to reach you about your car warranty"), the AI politely hangs up.
  3. Booking: If it's a customer ("My toilet is leaking"), the AI checks my calendar. "Mike can be there tomorrow between 2pm and 4pm. Does that work?"
  4. Notification: I get a text message: "Booked John Smith for Toilet Repair tomorrow @ 2pm. Estimated value: $300."

My Takeaway

If you are a service business owner, you are crazy if you are still answering your own phone. It is the lowest-leverage activity you can do.

You don't need to hire a person. You just need better software.
