Synthflow pricing in 2026: no public rate, and an alternative

At a glance

Synthflow is a platform for building AI voice agents. It is sold to contact centers, BPOs and large brands, mostly to answer their customers’ calls, and it plugs into the phone system and CRM they already run. TalaLevel is a sales CRM with the dialer, texting, email and AI inside it, and Joey is the AI caller in it. Most of the differences below come from that one choice.

Synthflow pricing, and what sits next to the bill

Synthflow’s pricing page has no plans and no figures. It says Synthflow “is sold as an annual enterprise agreement, scoped to your call volume, phone system, integrations, security needs and launch support. It has no free plan or trial and no rate by the minute.” The only buttons are Contact Sales and Get a demo. Its docs say the same: pricing is sales-led, and every new deployment starts on an Enterprise contract.

That is new this year. In June 2026 the same page sold pay as you go, with a rate card per minute for the voice, the model and the phone line, and an FAQ that put most setups at $0.15 to $0.24 a minute. By July that plan was gone and the page said “Enterprise contracts start at $30,000 annually.” In late October the $30,000 came off the page too. The Starter, Pro, Growth and Agency plans you still see on older blogs are no longer sold; customers already on them keep their limits.

What is still public is how a minute is counted. Synthflow’s usage docs count a call by the second from the moment the person and the agent connect. An unanswered call or a voicemail hang-up counts as 5 seconds, and a call where the agent leaves a voicemail counts in full. Your rate, your allowance, whether unused minutes carry over and what extra minutes cost are all set in your agreement. Concurrency, the number of calls running at once, is scoped in the agreement too.

Then there is what sits next to the bill. Synthflow sells numbers in the US, Canada and Australia for $1.50 a month each, and its docs recommend them for testing and your own Twilio account or a SIP trunk for production. Connecting your own carrier over SIP needs an Enterprise plan. Texts after a call go through Twilio, so the carrier registration for texting happens in your Twilio account. Twilio’s charges are Twilio’s, on its own bill. And your CRM is a separate subscription.

TalaLevel’s price is on its website, per seat per month:

• Dialer, $47. The CRM (leads, lists, pipeline, calendar, reports), unlimited US calling, a power dialer on one line, recordings and transcripts kept 30 days. Phone numbers are $2 a month each.
• Pro, $97. Adds up to three lines at once, texting from your own numbers with the carrier registration done with you, 2,000 texts and three numbers a seat, Tala with 1,500 AI credits a seat, the live call assistant, and email from your Gmail with follow-ups.
• Scale, $247. Adds Joey the AI caller, up to ten lines, 6,000 texts and ten numbers a seat, 5,000 AI credits a seat, listen, whisper and take over on reps’ calls, an onboarding call and priority support.

A minute of Joey uses about 10 AI credits, so a Scale seat covers about 500 minutes a month. More credits are $10 per 1,000, about 10 cents a minute, with the phone line, the voice, the model, the transcript and the recording all inside that. A year costs ten months.

Worked through for a month of AI calling, with one Scale seat and its credits used by Joey alone:

For scale, if the $30,000 a year floor Synthflow published until October were the whole bill, a minute would cost $5.00 at 500 minutes a month, $1.25 at 2,000 and $0.50 at 5,000. Synthflow never said how many minutes that floor included, so take those as a ceiling on what the floor alone buys, not as a quote.

Seats add reps as well as minutes:

Ten Scale seats, $2,470 a month, come in under the $2,500 a month that Synthflow’s last published floor works out to, and they include ten reps’ CRM, a ten-line dialer, texting and email, with 5,000 AI credits a seat for Joey and Tala.

Getting a list called

With Joey, you write his guide in plain words: your business, who you call, how the call goes, the greeting, the voice and how fast he speaks. Or you talk it through with Tala, the assistant in the app. Nothing is live until you press Go live. Then a person picks a list on the Calls page and sets it running. Joey never starts calling on his own.

With Synthflow, the agent is built in its Flow Designer or Prompt Builder, where you pick the model, the voice, the transcriber and the agent’s time zone. Then the list. Synthflow’s campaign docs say campaigns are available on Enterprise plans and are created through its API, with up to 10,000 people per request; the portal shows their progress. You can also start calls one at a time from HubSpot, GoHighLevel or Zapier, and its docs suggest a second between calls to stay inside the limit on new calls per second. A few rules from those docs matter for a sales list:

• Calling hours run on the agent’s clock. A campaign’s window, and the agent’s business hours, are set in the agent’s time zone, “never the caller’s”. A list spread across US time zones has to be split so each part calls in its own hours. Joey calls from 9am to 8pm in each lead’s own time zone.
• A campaign has seven days. Whatever is still queued after seven days is canceled.
• No automatic retry. People whose call failed are not retried; you send them again in a new request.
• Voicemail needs the right greeting. The agent can leave a voicemail, fixed or written from a prompt, but only when it waits for the person to speak first, and Synthflow notes that some greetings recorded in a person’s own voice get past its voicemail detection. Joey leaves one voicemail at most for each lead on each list, in words you approved.

Whichever you pick, judge it by people reached. On our own floor, over the same ten weeks, a person answered 5.9% of Joey’s calls and 8.4% of our reps’ calls.

During and after the call

Synthflow lets you listen in on a live call from its call logs, silently. When a call needs a person, the agent transfers it to a number you set. Recordings and transcripts are kept in Synthflow’s call logs, with switches to stop saving them or to delete them after 30 days; how long they are kept otherwise depends on your plan. To get calls into your CRM you install its HubSpot app, its Salesforce apps (Salesforce needs an Enterprise plan), or connect GoHighLevel, webhooks or Zapier. Its visual Workflows builder, for syncing calls into other systems, is on Enterprise only.

In TalaLevel, Joey’s calls land where your reps’ calls do. Every call is recorded, transcribed and filed on the lead, next to the reps’ calls, texts and emails. A rep can listen in on any of his calls and take the call over while it is going. If you switch it on, he sends one text, in words you set, when none of a run’s calls reach a lead. The same seat has the power dialer on up to ten lines, texting from your own numbers with the carrier registration done with you, email from your Gmail, and Tala, who answers leads by text, books calls and follows up.

Inbound, languages and building your own

This is where Synthflow is ahead, and it is a lot. Synthflow answers inbound calls as a receptionist, an answering service or a phone menu, and hands callers to a person with the transcript. It speaks 30+ languages and lets a caller switch language mid-call. It calls in 30+ countries, sells numbers in the US, Canada and Australia, and works inside phone systems like Zoom, Five9, RingCentral and 8x8, with Genesys and others over SIP. It has SMS, WhatsApp and web chat agents. For developers there is an API, webhooks, a visual flow builder and an MCP server, and its Trust Center lists SOC 2 Type 2, ISO 27001, HIPAA (self-attested) and PCI DSS v4.0.1.

Joey does one job: he calls a list in the US, in English, from inside the CRM. He is not an inbound receptionist or a phone tree. TalaLevel’s API and webhooks cover the CRM (leads, lists, deals, what happened on a call), not building agents: there is no visual flow builder, no choice of model or voice provider, and no SOC 2 report yet. If you are building a voice agent into your own product, or answering a contact center’s inbound calls, Synthflow is built for that and Joey is not.

Agencies and white-label

Synthflow’s agency page sells white-label voice AI: each client gets its own workspace under your brand and domain, with minutes allotted per client. It comes in the annual enterprise agreement. On September 15, 2026 Synthflow removed the built-in billing that let agencies charge clients through it, so agencies now invoice clients themselves, and its docs warn that with overage switched on a client’s usage “has no ceiling at all.”

TalaLevel has no white-label or resale program.

What reviewers say

Synthflow holds 4.5 stars from over 1,000 reviews on G2, and most praise how easy it is to set up. The complaint G2 tags most is price: “Expensive” (145 reviews) and “Cost Limitations” (97). One G2 reviewer, a business owner, wrote in May 2026: “It’s too expensive to bring your own phone system, if you don’t need the other enterprise features.” Another: “Once call minutes increase, the cost ramps up fast.”

Setup and who each is built for

Synthflow is bought through a demo and a scoping call, and its pricing page says a deployment “goes live in weeks.” Where the agreement includes launch support, its own engineers build, test and launch the agents with your team. It says it is built for “mid-market and enterprise teams deploying AI voice agents for customer calls”, and names contact centers, BPOs and multi-location brands; one customer runs it across more than 700 stores. On outbound, Synthflow says it “is built for calls with your own customers and with people who asked you to call them, not for cold calling,” and its terms ask you to confirm written permission from the contacts you import for AI voice calls.

TalaLevel is bought on its website. Pick a plan and start the seven-day trial with a card on file; there is no demo call, and you can talk to Joey in the browser first. Scale includes an onboarding call and priority support. It is built for any team that sells by phone and text, from one rep to a full floor, and sales teams outside our own floor run on it today. If your own CRM has to stay, we connect it with you. It calls and texts in the US only, has no iOS or Android app, and emails through Gmail only.

Which to pick

Pick TalaLevel if

• You want to see the price, sign up today and pay by the month, with no demo call and no annual contract.
• You want an AI caller with the minutes in the seat: about 500 a month for $247, then about 10 cents a minute, with the phone line, voice and recording inside.
• You want the AI caller inside the CRM your reps work in, with his calls on the lead next to theirs, and no phone system, numbers or model accounts to set up elsewhere.
• You call a US list and want each lead called between 9am and 8pm their own time, with one voicemail at most, in words you approved.
• You want a rep to listen in and take a call over, and the dialer, texting and email in the same seat.

Pick Synthflow if

• You need inbound calls answered: a receptionist, an answering service, a phone menu.
• You call outside the US or in languages other than English.
• You are building voice agents into your own product, with an API, webhooks and a flow builder.
• You run an agency or BPO and want to resell voice agents under your own brand.
• Your security review needs SOC 2 Type 2, ISO 27001 or PCI DSS papers, and you are buying an annual enterprise agreement.
