The problem
The call you miss is rarely the only thing you lose.
Most businesses do not lose customers because their service is poor.
They lose them because the moment failed.
- The phone rang while someone was busy.
- The inquiry came in after hours.
- The follow-up happened too late.
- The caller moved on.
That is all it takes.
SmartLine fixes that first moment — the one that decides whether the conversation continues or disappears.
The promise
Not a chatbot. Not a call center. Your own AI phone agent.
SmartLine is built for businesses that want speed without the usual friction.
That is the difference.

Why it converts
The easiest way to buy a phone agent should also be the easiest way to use one.
Most platforms make you work too hard before they let you find out whether the thing is useful.
SmartLine does the opposite.
It lowers the friction at the start, then earns the right to grow with you.
Integrations
Bookings land where your team already lives.
Connect Calendly and Google Calendar in one click. The agent texts callers your booking link; confirmed appointments sync back into SmartLine automatically.

Start ScaleCarrier compliance — read before you launch SMS or WhatsApp
US carriers and Meta require business verification before they let any platform — ours included — send SMS or WhatsApp at scale. These fees are charged by them, not us, and we walk you through the forms during onboarding.
SMS (US) — A2P 10DLC registration
- $4 one-time brand registration ($40 if Sole Proprietor)
- $15 one-time campaign vetting
- $10 /mo per active campaign
- Approval typically 1–3 business days; required by AT&T, T-Mobile and Verizon.
WhatsApp Business — Meta verification
- Free Meta Business verification (1–3 weeks)
- Need a phone number not on consumer WhatsApp and a legitimate business presence Meta can verify.
- Pay-per-conversation: ~$0.01–$0.09 per US session, billed by Meta via Twilio.
- Voice-only customers can skip both — phone agents work on day one.
Credit packs
Top up when you need to.

Comparison
Why SmartLine beats the usual alternatives
The usual way
Asks for too much too early.
- Weeks of setup.
- Sales calls before access.
- Monthly minimums before proof.
- Outbound hidden behind enterprise upgrades.
- Contract language before real value.
SmartLine
Is different.
- Live in minutes.
- Self-serve from the first click.
- Outbound included.
- Forward your number or port it.
- Plans from $49/mo, 7-day trial, and $4 usage credits to test real calls.
- Cancel anytime · no contract.
The easiest product to start is often the one that gets tested.
The one that gets tested is the one that gets adopted.
Cost angle
One saved call can pay for months.
A receptionist costs money whether the phone rings or not. SmartLine costs almost nothing to start, and scales with actual usage.
- No sick days.
- No turnover.
- No training cycle.
- No one-call-at-a-time bottleneck.
- No dead hours where nobody answers.
For many businesses, one booked appointment or one recovered lead can pay for months of usage.
Trust
Serious where it matters.
SmartLine is built to feel simple on the front end and serious on the back end.
This is not a toy with a pretty voice. It is a real business system with a very low-friction starting point.
Who it is for
Built for businesses that cannot afford to sound unavailable.
If a live conversation matters to your revenue, SmartLine matters to your business.
FAQ
Questions people ask right before they decide
Do I have to buy credits immediately?
No. Paid plan checkout starts a 7-day trial and adds $4 in usage credits so you can test real calls first. Free accounts can buy credit packs when they are ready to run paid usage.
So what does SmartLine actually charge me?
Registration is free. Paid plans are $49/mo, $149/mo, or $299/mo after the 7-day trial unless you cancel before billing starts. Usage like voice minutes, SMS, and phone numbers is deducted from your credit balance.
When am I billed for the monthly plan?
After the 7-day window ends. The subscription is month to month from there. You can cancel inside the 7-day window and you are not billed for the monthly plan.
Is there a longer free trial?
You can explore for free before paid provider actions. The 7-day plan trial starts when you choose Starter, Growth, or Scale. If you stay on the free account, buy usage credits before running provider-cost actions.
Can I keep my current number?
Yes. Forward it in seconds, or port it fully if you want SmartLine to own the line.
Can it do outbound too?
Yes. Outbound campaigns, lead follow-up, reminders, and voicemail drop are built in.
Why does sending SMS need extra registration?
US carriers (AT&T, T-Mobile, Verizon) require A2P 10DLC business registration before any platform — ours included — can send SMS to US numbers. You pay this directly through Twilio: about $4 one-time brand registration ($40 if you're a Sole Proprietor), $15 one-time campaign vetting, and $10/month per active campaign. Approval usually lands in 1–3 business days. Voice-only customers don't need this. We walk you through every form during onboarding.
What about WhatsApp Business?
WhatsApp requires Meta to verify your business — free, but typically takes 1–3 weeks. You'll need a phone number that isn't currently on consumer WhatsApp and a real business presence Meta can match against (a website, Google Business profile, or LinkedIn). Once verified, conversations are billed per session by Meta through Twilio (roughly $0.01–$0.09 per US conversation depending on category). We help you submit the verification and pick a number that qualifies.
Will it sound robotic?
No. SmartLine uses modern real-time AI voice, not old-style text-to-speech.
What if I want to stop?
Cancel from your account in one click. Stop inside the 7-day window and you are not billed for the monthly plan. Stop after that and the current month finishes out — no clawback, no contract.
What about my data?
Your data remains yours. Export it. Delete it. Keep control.
The smartest way to test an AI phone agent is to put it on the line.
Not after a sales process.
Not after a contract.
Not after a long implementation.
