Which AI Phone Receptionist Is Best?

The best AI phone receptionist is the one that answers when your team cannot, collects the right facts, and gets a person for calls that need judgment. Published monthly prices start at $49 for Sera, $79 for Goodcall, and $199 for NextPhone.

This comparison is for local service owners who miss calls while driving, working a job, seeing customers, or handling payroll. I ranked only tools with price and product details on the company’s own site, so the facts can be checked.

TL;DR: Sera starts at $49 per month for 24/7 calls and messages. Appointment booking, missed-call texts, live transfers, and multiple languages require the $499 Growth plan. Goodcall starts at $79 per month, and NextPhone starts at $199 per month.

How Did I Pick These AI Phone Receptionists?

I compared each company’s published price, after-hours coverage, booking options, transfers to a person, and stated limits. I did not make matching test calls across every product, so I do not grade voice quality or claim one sounds more natural than another.

Here was the selection rule:

• The company publishes pricing I can link to.
• The product can answer calls after hours or 24/7.
• The product can collect caller details or book time.
• The product has a clear way to get a person involved.
• The plan limits are clear enough for an owner to budget.

That leaves three ranked options here: Sera, Goodcall, and NextPhone.

I left out Smith.ai, Reception.ai, RingCentral AIR, and several others from the ranked table. They may be good products, but I could not cite their own product and pricing pages for this article. I would rather keep the list shorter than repeat unsourced prices.

Which AI Phone Receptionist Fits Your Business?

The right choice depends on how customers reach you, how many different people call each month, and whether you need booking or live transfers. The cheapest starting price is not always the lowest real price once you add the work your front desk actually needs done.

Option	Best for	Published starting price	Ways customers can reach it	After-hours coverage	What to check first
Sera by Twig	Calls plus messages in one place	$49 per month	Phone, SMS, web chat, email, WhatsApp	24/7	Booking and live transfers start at $499 per month
Goodcall	Phone-first answering	$79 per month	Phone	24/7	Price depends on unique customers
NextPhone	Heavy phone call volume	$199 per month	Phone; can text callers links and confirmations	24/7	Higher starting price than Sera or Goodcall

Is Sera the Best AI Phone Receptionist for You?

Sera is the best fit if missed calls are only part of the problem and customers also reach you by text or web chat. Sera is weaker if you only need the cheapest phone-only tool, or if you need HIPAA compliance or a direct connection to special industry software on day one.

Twig makes Sera, our AI front desk. Sera is an AI receptionist: she answers every call, text and web chat 24/7, qualifies the caller, and books them with your team.

Best for: local service businesses that want one AI receptionist across phone, SMS, web chat, email, and WhatsApp. Every conversation is logged with a full transcript, so the owner or office manager can see what happened.

Watch out for: Sera is not HIPAA compliant and does not sign BAAs. If your business needs HIPAA controls, read this first: Is a HIPAA-compliant virtual receptionist safe?.

Sera should send pricing exceptions, safety questions, complaints, and other judgment calls to a person. The business sets those rules.

Pricing: Sera starts at $49 per month. Every plan starts with a 15-day free trial, voice included, and no credit card. Self-serve signup does not require a sales call.

Appointment booking, missed-call text-back, live transfers to a person, and multi-language conversations are included on Growth at $499 per month and above. They are not included on Starter.

Most businesses can be live in under 30 minutes by forwarding the phone line or adding the website chat. You can also call Sera’s live demo line at (650) 795-7838.

Situation	Why Sera fits	What to check first
You miss calls after 5 pm	Sera answers 24/7	Who should get urgent calls
Customers text and call	One agent covers calls and messages	Which number receives texts
You want transcripts	Every conversation is logged	Who reads them each morning
You need appointment booking	Included on Growth and above	Calendar rules and open slots
You use Gmail, HubSpot, Salesforce, or Slack	Conversation notes can go there	Exact fields your team needs

Is Goodcall the Best AI Phone Receptionist for You?

Goodcall is the best fit if you want a phone-first AI answering service and like pricing by unique customer instead of minutes. Goodcall’s own site says its AI phone agent answers 24/7, captures leads, books appointments, and sends caller details by text and email.

Best for: owners who want to describe the business in plain words and have the phone agent answer calls, ask questions, book time, and send caller details. Goodcall’s homepage shows examples for lead capture, booking, customer-system notes, and store questions.

Watch out for: Goodcall prices by unique customer per month. That can be simple, but you should estimate how many different people call you in a busy month.

Goodcall’s pricing page says one phone number counts once a month. If the same person calls back five times in March, that is one customer. Spam and wrong numbers do not count.

Pricing: Goodcall lists Starter at $79 per month, Growth at $129 per month, and Scale at $299 per month. The same page says it does not meter minutes and extra customers bill at the plan’s listed extra-customer rate.

Choose Goodcall when the phone is the main problem, and you want a bill tied to different callers rather than call length.

Is NextPhone the Best AI Phone Receptionist for You?

NextPhone is the best fit if most new work starts with a phone call and you want unlimited inbound calls on a flat monthly plan. Its starting price is higher than Sera and Goodcall, but the official pricing page says there are no per-minute charges or overage fees.

Best for: local businesses that book jobs by phone and want calls answered 24/7. NextPhone’s pricing page says Pro includes unlimited inbound calls and users, booking into Google and Outlook calendars, call transfers, transcripts, and SMS and email alerts.

Watch out for: the starting plan is $199 per month. A very small shop should compare that against the actual cost of missed calls. If you only miss a few calls each month, a lower starting price may make more sense.

Pricing: NextPhone lists Pro at $199 per month, Growth at $299 per month, and Scale at $599 per month. The page says Pro is self-serve, while Growth and Scale are set up by the NextPhone team.

NextPhone also says Scale includes 2-way texting from your number and custom connections to your software. Do not assume those are included on the $199 plan.

Choose NextPhone when most customers call, you want unlimited inbound calls, and $199 per month fits your budget.

Which Products Did I Leave Out?

I left out products when I could not cite the company’s own pricing and product pages for this article. A longer list with uncited prices looks helpful at first, but it can send an owner into a sales call with the wrong budget.

That is why this article does not rank Smith.ai, Reception.ai, RingCentral AIR, or other tools named in published reviews. If you want to compare one of them, ask the company for current pricing, what the starter plan includes, and whether a person can join urgent calls.

Use the same questions for every company:

• What is the monthly price?
• What costs extra?
• Does the starter plan book appointments?
• Can it transfer urgent calls to a person?
• Can it send caller details to the system your team already uses?
• What happens when the caller asks something it should not answer?

If the answer is vague, do not buy yet.

What Calls Should You Test Before You Buy?

Test the calls that cost money when handled badly, not the easy demo call. A good test uses your business name, your hours, your service area, your urgent-call rules, and the messy calls your team gets every week.

Here is the worked example I would use for a plumbing, HVAC, electrical, dental, medspa, auto shop, or professional office.

After-hours script to test:

“Hi, I found you on Google. I have water coming through the ceiling. I’m at 218 Maple Street. Do you come out tonight, and what does it cost?”

The AI should not ramble. It should collect the facts and get a person if that is your rule.

What the AI should ask	Why it matters	Good answer from the AI
Name and callback number	Your tech needs it	“Can I get your name and best number?”
Address or service area	Confirms you serve them	“What address is this for?”
Problem and urgency	Separates routine from urgent	“Is water still actively coming in?”
Safety issue	Protects the caller	“If there is electrical risk, please stay clear.”
Next step	Sets expectations	“I’m sending this to the on-call team now.”

My firm recommendation: do not buy until you make five test calls.

1. A normal new customer asking for service.
2. An urgent after-hours call.
3. A caller asking for a price you do not quote over the phone.
4. A wrong number or spam call.
5. An upset returning customer.

Then read the transcript. If your dispatcher, office manager, receptionist, or manager would not know what to do next, fix the script or pick another tool.

How Should You Choose?

Choose based on the calls you actually miss, not the feature list that sounds best. The right tool for a solo contractor is not always the right tool for a multi-location office with several people answering phones.

Use this simple rule of thumb:

• Choose Sera if you want calls plus texts, website chat, email, and WhatsApp in one AI front desk.
• Choose Goodcall if you want phone-first answering and like unique-customer pricing.
• Choose NextPhone if you want unlimited inbound calls and the $199 starting price makes sense.

Then check the plan details. With Sera, booking and live transfers start on Growth at $499 per month. With Goodcall, you need to estimate unique customers. With NextPhone, you need to decide whether the higher starting price matches your call volume.

The hidden question is not “Can AI answer the phone?” Most of the time, yes. The hidden question is “Will my team trust what happens after the call?”

What Is the Next Step?

Pick two tools, make the same five test calls, and compare the transcripts before you spend a full month’s budget. If one tool cannot handle your real after-hours call, do not assume it will improve once real customers are on the line.
