We compared the 10 best white-label AI voice agent platforms for agencies and resellers on the numbers that decide whether you make money: monthly fee, minutes included, the real per-minute rate, Stripe rebilling, subaccounts, and whether you need your own API keys. Short version: Autocalls is the best pick for most agencies (Agency from $249/mo with 1,700 minutes, Agency White Label $419/mo with 3,500 minutes, $0.09 per extra minute with the models, voices and transcription included, Voice + WhatsApp + Chat). Trillet, PulsyAI and Stammer are the cheapest monthly entries. Prices checked 21 September 2026.
The white-label voice AI market got crowded fast. In 2024 there were three or four platforms offering any kind of rebranding. In 2026 there are over a dozen, the biggest name in no-code (Synthflow) just left the self-serve market, and most "best of" lists are written by one of the platforms ranking itself first. We're a platform too, so judge for yourself: every claim below is checkable, every price comes from a public pricing page with the date we checked it, and we say where competitors beat us. If you want the full agency how-to instead of a platform comparison, read our complete white-label AI voice agent guide.
What "Full White-Label" Actually Means (Most Platforms Fall Short)
"White-label" is used loosely. A logo swap is not a white-label business. Before you commit to a platform, check it against this list:
| Feature | Basic white-label | Full white-label |
|---|---|---|
| Custom logo and colors | ✅ | ✅ |
| Custom domain and favicon | ❌ | ✅ |
| Stripe rebilling to your clients | ❌ | ✅ |
| Client self-service portal | ❌ | ✅ |
| Unlimited subaccounts | ❌ | ✅ |
| Platform name fully hidden | ❌ | ✅ |
| Voice + WhatsApp + Chat under your brand | ❌ | ✅ (rare) |
Why it matters: if your clients can discover the platform behind you, you don't own the relationship. If you can't bill through your own Stripe, you're a referral partner, not a SaaS owner.

Detailed Platform Reviews
1. Autocalls: best all-in-one omnichannel white-label platform ★
Best for: agencies and resellers who want everything included: no API keys, no provider accounts, no dev team. Build agents with the no-code wizard, rebrand the platform, bill your clients through your own Stripe.
Autocalls is the only platform on this list that is all-inclusive and omnichannel at the same time. OpenAI, ElevenLabs, Cartesia and Deepgram are built in, so the $0.09 rate covers the language model, the voice, the transcription and the Dualplex™ call engine. It is also the only platform that white-labels three channels natively: AI phone calls, WhatsApp Business agents and website chat, all under your domain and your brand.
| Agency | $249/mo, 1,700 minutes included, then $0.09 per minute. Unlimited assistants, 500 parallel calls. Your clients' agents run inside your own account and you invoice clients yourself; there are no client logins or Stripe rebilling on this tier. The right entry if your clients do not need their own branded login on day one. |
| Agency White Label | $419/mo, 3,500 minutes included, then $0.09 per minute. Full rebrand, 1,000 parallel calls, unused minutes roll over. Yearly billing: 2 months free. |
| What's included | Custom domain, logo, colors, favicon, branded emails and docs. Stripe rebilling so clients pay you directly at prices you set in the plan builder. Client self-service portal. Your clients never see the Autocalls name. |
| Channels | Voice + WhatsApp + Web Chat (the only full omnichannel white-label) |
| Voice quality | Dualplex™ engine: lowest latency in the group we tested, natural interruption handling, ElevenLabs and Cartesia voices |
| Reach | 100+ languages, phone numbers in 150+ countries, 300+ no-code integrations |
| Proof | 4.9/5 on G2, 5.0 on Capterra and Trustpilot, ISO 27001:2022 and ISO 9001:2015 certified, GDPR compliant, HIPAA available, 700+ agencies on the platform. Read the reviews. |
Where competitors beat us: Trillet, PulsyAI and Stammer all have a cheaper monthly entry ($99 to $299) if you only need a handful of minutes to start. VoiceAIWrapper is the right choice if you already run on Vapi or Retell and only want a branded shell. If you are a developer who wants raw pipeline control, Vapi gives you more knobs (without white-label).

2. Trillet: the closest all-inclusive rival, fewer minutes in the box
Best for: agencies that want a modern all-inclusive platform and are fine paying for most of their minutes on usage.
Trillet's Agency plan is $299/mo with 300 minutes and unlimited workspaces; Studio is $99/mo with 100 minutes and up to 3 workspaces. AI usage is $0.12 per minute and covers the platform, speech-to-text, the LLM and the voice; US telephony is billed separately from $0.014 per minute, so a real phone minute lands at about $0.134. Ten phone numbers are free on Agency. No API keys needed, Stripe rebilling included.
Pros: clean product, all-inclusive rate, strong partner marketing. Cons: 300 included minutes at $299 versus 1,700 at $249 on Autocalls Agency; the per-minute rate is about 49% higher than $0.09 once telephony is added; voice and web only, no WhatsApp channel.
3. PulsyAI: cheapest monthly entry with real minutes, rate unpublished
Best for: solo operators testing the reseller model who want the lowest fixed cost and can live with an unpublished overage rate.
PulsyAI's Agency white-label plan is listed from $99/mo with 1,000 minutes included, unlimited sub-accounts, native Stripe Connect, and no API keys required. It lists voice, SMS, email and chatbot channels and lets partners set their own per-minute price. What the partner page does not show is the price of minute 1,001: the overage rate is not published, and neither is the phone number cost.
Pros: lowest monthly fee with a real minute allowance, Stripe Connect, no BYOK. Cons: no published per-minute rate, so you cannot model margin past the included minutes; young platform with a thin public track record; no ISO or HIPAA claims on the site; no WhatsApp Business channel.
4. VoiceAIWrapper: cheapest shell if you already pay Vapi or Retell
Best for: agencies already running on Vapi, Retell, Ultravox or ElevenLabs Agents who just want branded dashboards, client portals and Stripe billing.
VoiceAIWrapper is not a voice engine. It is a white-label layer over your own provider accounts: Growth $79/mo (5 client accounts, $15 each after), Scale $249/mo (10 clients, $12 each after), Pro $499/mo (20 clients, $10 each after). Minutes are billed by your provider at cost, which the site puts at $0.05 to $0.31 per minute depending on the stack, with no markup from VoiceAIWrapper.
Pros: cheapest way to test the agency model on top of a stack you already run, zero markup on minutes. Cons: two or three vendors instead of one, per-client fees, voice only, your real cost is subscription + provider + telephony, and you manage every provider account and key yourself.
5. Stammer: chat-first white label with voice on usage
Best for: agencies selling AI chat agents first, with voice as an add-on.
Stammer's Pro White Label plan is $99/mo with full rebranding, custom domain, 5+ chat and voice agents, white-label API access and the option to bring your own LLM keys. Voice minutes are not included in the plan; they are billed per minute by model, from $0.11 (GPT-4.1-nano) to $0.17 (Claude Sonnet). Clients pre-load funds into sub-account wallets and usage is deducted, so there is no Stripe subscription billing in the Autocalls sense.
Pros: low fixed cost, mature chat product, flexible model choice. Cons: voice is the second product, per-minute rates are 22% to 89% above $0.09 with no minutes included, and the prepaid wallet model makes recurring SaaS billing harder to run.
6. ConvoCore: multichannel credits, no flat voice rate
Best for: technical agencies that want chat, WhatsApp, Instagram and voice under one credit pool and can model credit burn.
ConvoCore's White Label plan is $199/mo with 60,000 credits and 20 sub-accounts; White Label Elite is $349/mo with 120,000 credits, SaaS mode, client self-signup and unlimited clients. Voice calls consume credits, so the cost per minute depends on how many credits a minute burns; there is no flat published per-minute figure.
Pros: broad channel list, self-signup SaaS mode on Elite, free tier to test. Cons: credit maths instead of a per-minute price, 20-client cap on the $199 plan, voice is one feature among many rather than the core.
7. HighLevel: CRM first, voice AI as a paid add-on
Best for: agencies already living in HighLevel who want to add a phone agent to the CRM they resell.
HighLevel's Agency Pro plan is $497/mo and includes SaaS Mode for reselling under your brand. Voice AI is usage-based on top, and the AI Employee bundle is $50/mo (Growth) or $97/mo (Unlimited) per sub-account. It is a CRM and marketing suite with a voice agent inside, not a voice platform.
Pros: if you already resell HighLevel, the AI is one toggle away. Cons: $497 before a single AI minute, per-sub-account AI fees stack on top of usage, and the voice quality, latency and language coverage are not the product's focus.
8. Callin.io: $0.10 per minute, tiers on request
Best for: agencies that want a straightforward per-minute price and are happy to ask for the plan details.
Callin.io's white-label page lists $0.10 per minute with no setup fee. Plan tiers, included minutes and client limits are not published on the page; you get them from sales. Voice only.
Pros: a simple per-minute number. Cons: 11% above $0.09 with no published plan structure, voice only, no WhatsApp or chat.
9. My AI Front Desk (Frontdesk): receptionist-only resale
Best for: resellers focused purely on AI receptionists for dental, legal and medical offices.
A white-label reseller program with custom wholesale pricing starting around $500/mo, apply-based, with one-click Stripe billing and unlimited client subaccounts. Resellers set any price ("charge $49 or $999"). It does inbound reception well; it is not built for outbound campaigns or WhatsApp. See our My AI Front Desk review.
10. Synthflow: white label is now a $30,000-a-year enterprise contract
Best for: large agencies with a sales-led buying process and the budget for an annual enterprise deal.
Synthflow was the best-known no-code voice builder with self-serve reselling. That ended on 15 September 2026: in-product reselling (Stripe billing of subaccounts, auto top-ups, overage billing, margin calculator) was removed, and the pricing page now lists a single Enterprise plan with a $30,000 annual minimum, scoped around volume, concurrency and telephony. The product is still strong on compliance (SOC 2, HIPAA) and templates; it is no longer a self-serve white-label option.
Pros: mature builder, enterprise compliance and SLAs. Cons: no self-serve white label, $30k minimum, voice only. If you are migrating, we wrote a step-by-step guide.

The Hidden Cost of BYOK (Do This Math Before You Sign)
VoiceAIWrapper bills provider minutes at cost, Stammer lets you bring your own LLM keys, and several smaller platforms advertise headline rates under $0.07/min that assume you pay the providers yourself. Here's what BYOK actually costs at retail rates:
| Provider | What it does | Retail cost |
|---|---|---|
| ElevenLabs | Voice synthesis | ~$0.20/min |
| Deepgram | Speech-to-text | ~$0.01/min |
| OpenAI | LLM inference | ~$0.02-0.05/min |
| Telephony | Phone connection | ~$0.01-0.02/min |
| Real BYOK total | Before any platform fee | $0.24-0.28/min |
| Autocalls all-inclusive | Everything above, included | $0.09/min |
Platforms with built-in providers negotiate bulk rates and pass the savings on. BYOK shifts the cost and the account management to you. If your business model depends on margin per minute, this single line item decides it.
The Omnichannel Gap Most Comparisons Skip
Your clients' customers don't just call. They message on WhatsApp and they open the chat widget on the website. The first time a client asks "can you also handle our WhatsApp?", a voice-only white label forces you to bolt on a second platform with separate billing and a separate brand. Your "own SaaS" suddenly looks stitched together.
Of the ten platforms here, only Autocalls white-labels voice, WhatsApp Business and web chat natively, in one dashboard, at one all-inclusive rate. ConvoCore and Stammer are chat-first with voice on credits or usage, PulsyAI lists SMS and email alongside voice, HighLevel is a CRM with a voice add-on, and Trillet, VoiceAIWrapper, Callin.io, My AI Front Desk and Synthflow are voice (plus web calls) only. If omnichannel is part of your offer, and in 2026 it should be, your shortlist is short.
Margin Math: What Agencies Actually Make
A typical white-label client pays $300 to $600 a month for an AI agent handling their calls. Here is the unit economics on both Autocalls agency plans, with the same client on a BYOK stack for comparison:
| Scenario | Your monthly cost | Gross margin |
|---|---|---|
| 5 clients at $300, about 300 minutes each (1,500 min) on Agency $249 | $249, minutes inside the 1,700 allowance | $1,251 profit on $1,500, about 83% |
| 10 clients at $500, about 1,000 minutes each (10,000 min) on Agency White Label $419 | $419 + 6,500 extra minutes × $0.09 = $1,004 | $3,996 profit on $5,000, about 80% |
| Same 10 clients on a BYOK stack at about $0.26 per minute real cost | About $2,600 in provider bills before any platform fee | About 48%, plus you babysit four provider accounts |
The $249 Agency plan is the entry most agencies should start on: five clients pays the platform four times over. Move to Agency White Label when clients need their own branded login and you want Stripe to bill them automatically, or when your volume passes about 3,500 minutes a month and the rollover starts to matter. The full financial models, pricing strategies and the 30-60-90 launch plan are in our free playbook (linked below).
How to Choose: Match the Platform to Your Situation
| Your situation | Go with | Why |
|---|---|---|
| Non-technical agency, want one platform for everything | Autocalls Agency White Label | All providers built in, no-code wizard, full white label with Stripe rebilling, Voice + WhatsApp + Chat |
| Starting out, first 5 to 10 clients, brand can wait | Autocalls Agency ($249) | 1,700 minutes and unlimited assistants at the lowest all-inclusive rate; upgrade to white label when clients need their own branded login and Stripe billing |
| Best possible margin per minute | Autocalls | $0.09 all-inclusive vs $0.12 + telephony (Trillet), $0.11 to $0.17 (Stammer) or $0.24+ on BYOK |
| Lowest monthly fee, few minutes, testing the model | Trillet Studio or PulsyAI | $99 entries; check the overage rate before you sell a plan |
| Already on Vapi/Retell, just need branding | VoiceAIWrapper | Purpose-built shell from $79/mo, minutes at provider cost |
| Chat agents first, voice second | Stammer or ConvoCore | Chat-first products with voice on usage or credits |
| Already reselling HighLevel | HighLevel Agency Pro | Voice AI inside the CRM you already sell, at $497 plus usage |
| Receptionist-only niche play | My AI Front Desk | Narrow but proven receptionist product |
| Enterprise procurement with an annual contract | Synthflow Enterprise, or Autocalls with a DPA and SLA | Synthflow starts at $30k/year; Autocalls signs DPAs, is ISO 27001 certified and offers HIPAA for healthcare partners |
