LastWorker vs Google Voice: One Forwards Calls, One Answers Them

A dentist I worked with ran his whole front desk through a Google Voice number for two years. Cheap, simple, one number that rang his cell and the office. It worked fine right up until it didn't. The moment two calls came in at once, or someone called during a cleaning, the caller hit voicemail. Most of those people never left a message. They just called the next office on the list. He thought he had phone coverage. What he actually had was a forwarding rule.

That is the core thing to understand here. Google Voice and LastWorker get compared because both involve a phone number, but they are built for completely different jobs. One moves a call from point A to point B. The other talks to the person on the line.

What Google Voice actually is

Google Voice is a free (or cheap, if you go the Workspace route) phone number that forwards to your real phones and takes voicemail when nobody picks up. It does a few things genuinely well:

• Gives you a second number so you don't hand out your personal cell.
• Sends and receives basic SMS.
• Transcribes voicemail into text and emails it to you.
• Rings multiple devices at once.

For a freelancer, a solo consultant, or anyone who wants to keep work and personal calls separate, that is a perfectly good tool. I have recommended it for exactly that. If you are a one-person operation and you answer your own phone most of the time, Google Voice plus your own two hands is a reasonable setup.

What it does not do is the part that matters most for a business: it does not answer. There is no one on the other end when you are busy. The caller gets your recorded greeting and a beep. Google Voice cannot tell a caller your hours, quote a price, book a slot, or take down enough detail for you to call back with context. It captures a phone number and, if you are lucky, a rambling thirty-second message. The free Workspace tiers also auto-attendants and ring groups exist, but those are menus and routing, not conversation. A phone tree is not an answer either.

What LastWorker does instead

LastWorker is an AI that actually picks up. It answers your phone, your website chat, your SMS, and your email, around the clock, in 97 languages, and the voice replies come back in under a second and sound like a person rather than a robot reading a script.

You set it up in about a fifteen-minute conversation. You tell it your services, your prices, your hours, your policies, the questions you get sick of answering. From then on it handles the call. It answers the question, books or reschedules the appointment, captures the lead with real detail, takes a message when that is the right move, and transfers or escalates to a human when something genuinely needs one.

The difference shows up in the calls you never see with Google Voice. A new patient calling at 7 p.m. to ask if you take their insurance and whether you have anything Thursday: Google Voice sends them to voicemail. LastWorker tells them yes, you take that plan, and books them for 2:15 Thursday before they hang up. That call is worth real money. In the home services shops I worked with, a single booked job often cleared a few hundred dollars, sometimes a few thousand. Missing a quarter of those calls, which is roughly what I saw at shops relying on voicemail, is not a phone problem. It is a revenue problem.

Side by side

The honest cost comparison

Google Voice wins on raw price. Free for personal use, and a few dollars a month inside Google Workspace. Nothing I write here changes that. If price is the only axis you care about and you are fine answering your own calls, stop reading and go set up Google Voice.

LastWorker is not free, but it is not a fat monthly subscription either. There is no monthly fee. You load a prepaid balance and pay only for the conversations it actually handles. Voice is billed per second at $0.05 a minute, chat and SMS per message, email per resolved ticket. A dedicated number is $1 a month if you want one, and you can turn on auto-reload so the balance never runs dry mid-day. The full breakdown is on the pricing page.

So the real question is not "which is cheaper." It is "what does a missed call cost me." If your answer is "nothing, I'd have answered it myself," Google Voice is plenty. If your answer is "a booked job," then paying a few cents to have something pick up and book it tends to pay for itself by lunch.

Where Google Voice is genuinely the better pick

I am not going to pretend LastWorker is right for everyone. Pick Google Voice if:

• You are a solo operator who answers your own calls and just wants a work number.
• Your call volume is low and you are rarely unavailable.
• You mostly need voicemail and basic texting, nothing booked or quoted.
• Budget is the hard constraint and zero dollars is the target.

There is no shame in that setup. I have run small operations where a second number and a notepad were exactly enough.

Where LastWorker is the better pick

Move to LastWorker when missed calls start costing you:

• You lose calls because you are with a customer, on a job, or asleep.
• Callers want answers (hours, pricing, availability) and you want bookings, not messages.
• You get inquiries across phone, chat, text, and email and can't watch all four.
• You serve customers who speak more than one language.
• One booked appointment is worth more than a month of conversation fees.

If you want to see how this stacks up against actual answering services and the other AI tools, the comparisons page lays those out too.

The simplest way I can put it: Google Voice decides which phone rings. LastWorker decides what the caller hears, and whether they end the call as a booking or a lost lead. A dental group that switched stopped losing the 7 p.m. insurance callers within the first week, and they had assumed those calls just didn't exist. They existed. They were going to voicemail, and voicemail was going in the trash. If your business lives or dies on the calls you don't get to answer, a forwarding rule was never going to save you. Something has to pick up.
