Missed calls are costing you money right now
Most callers don't leave voicemails. They hang up and call your competitor. You never even know the lead existed. Firstback makes sure every missed call gets an immediate response — so you stay in the running.
How it works
Three steps. Completely automatic after setup.
Customer calls you
They dial your normal number — nothing changes for them.
You miss the call
You're busy, on a job, or just can't answer.
They get a text instantly
Firstback sends your custom reply automatically. They reply, you get it.
Hey! Sorry we missed your call — how can we help? We'll get back to you shortly.
Delivered instantly
Hi! My AC stopped working. Can someone come out today?
Don't let another lead slip away.
Setup takes 2 minutes. First 7 days are free.
Built for businesses that run on phone calls
If customers call to book, inquire, or get a quote — Firstback is for you.
What business owners say
“I used to lose leads all the time when I was on a job. Now every missed call gets a text immediately. Got a $4,000 job from a lead I would have never known about.”

Common questions
Do I need to change my phone number?
No. You keep your existing number. Callers still dial you normally — unanswered calls simply forward to your Firstback number behind the scenes.
What if I answer the call?
No SMS is sent. The auto-reply only fires when the call goes unanswered.
Can I customize the message?
Yes — you write your own message during setup and can edit it anytime.
What happens when they text back?
Their reply is forwarded as a text to your real phone. You reply normally — they never know the difference.
How do I cancel?
Cancel anytime from your settings page. No phone calls, no hoops.
