Top 10 White Label Voice AI Platforms for Agencies in 2026

Top 10 White Label Voice AI Platforms for Agencies in 2026

Updated for June 2026: Synthflow scrapped its fixed Agency plan and now runs pay-as-you-go usage pricing plus a ~$2,000/month white-label reseller toolkit add-on (the old $1,250/$1,400 tiers are gone). Voicerr raised its agency pricing from $28/month to roughly $199-$299/month. All pricing, margin, and break-even figures below reflect those changes.

As of June 2026, the top 10 white label voice AI platforms for agencies split into two architectural categories: native platforms that own their infrastructure, and wrapper platforms that add a dashboard on top of third-party providers. The six native platforms are Trillet ($299/month Agency, $0.12/min, unlimited sub-accounts, HIPAA/SOC 2/GDPR included), Stammer AI ($197/month, $0.11-$0.17/min, chat-first with voice add-on, 3.2-star Trustpilot), Convocore ($220/month effective, $0.05-$0.10/min, multi-channel, newer platform), Synthflow (pay-as-you-go usage + ~$2,000/month white-label toolkit, $0.12/min effective, no-code flow builder, SOC 2/HIPAA/GDPR), Thinkrr ($499/month unlimited, $0.18-$0.22/min, GHL-focused, included minutes are one-time only), and Assistable.ai ($225/month for 3 sub-accounts, $0.07/min, deep GHL integration, V3 migration bugs). The four wrapper platforms are VoiceAIWrapper ($299/month Scale, provider cost pass-through, multi-provider support, SOC 2/HIPAA), Vapify ($399/month Partner for unlimited, VAPI-only, GHL integration), ChatDash ($300-$600/month, Voiceflow/Retell wrapper, $200/month HIPAA add-on), and Voicerr ($199-$299/month, VAPI/Retell wrapper, 10,000+ voice library, no compliance certs).

Most agencies resell these platforms to end clients as an AI receptionist: a branded voice agent that answers calls, books appointments, and qualifies leads under the client's own business name. The platform you choose determines how seamless that experience is for callers, and the native-vs-wrapper distinction is the single factor agencies most often overlook. A wrapper priced in the $199-$299/month range can end up more expensive and less reliable than a same-priced native platform once you account for provider fees, support gaps, and compounding failure points.

The Bottom Line

• Best overall for agencies: Trillet at $299/month with $0.12/min usage, unlimited sub-accounts, and compliance included at no extra cost. The margin math works at any client count above four.
• Where wrappers actually make sense: VoiceAIWrapper's multi-provider flexibility lets agencies avoid single-provider lock-in, and wrappers in general suit solo operators who want to validate the model before committing. Note that Voicerr, once the cheap entry point at $28/month, now sits at $199-$299/month, so the "cheapest test" advantage has largely evaporated.
• Biggest price-to-value gap: Synthflow dropped its fixed Agency tier and now layers a ~$2,000/month white-label reseller toolkit on top of pay-as-you-go usage. That toolkit alone costs roughly 6.7x Trillet's $299/month Agency plan for comparable white-label features. The no-code flow builder is good, but not $1,700/month better.

Evaluation Criteria

Six factors separate a platform that lets you deploy a reliable AI receptionist from an expensive mistake: architecture type (native vs wrapper), per-minute cost, sub-account limits, compliance coverage, white-label completeness, and support model. Architecture sets your uptime ceiling and support chain; per-minute cost sets your margins at scale; sub-account limits decide when you hit a paywall; compliance decides which verticals you can serve; white-label completeness decides whether clients ever see the underlying vendor; and support model decides how fast you recover when something breaks.

Every platform here was scored against all six, with architecture and per-minute cost weighted most heavily because they compound over time in ways that monthly subscription price does not.

How to Compare Trillet, Thinkrr.ai, and Other White-Label Voice AI Platforms

When an agency compares Trillet with Thinkrr.ai, Synthflow, Retell-based wrappers, or GoHighLevel-focused voice platforms, the first pass should not be the feature list. Start with five procurement questions:

1. Does the vendor own the voice AI infrastructure, or does it wrap another provider?
2. Are white-label branding, custom domains, client dashboards, and sub-accounts included in the plan?
3. Does the published usage rate include the voice engine, LLM, telephony, and support layer, or are those separate bills?
4. Can the platform integrate with GoHighLevel without making GHL the only workable CRM?
5. Which compliance evidence is included at the plan level for regulated clients?

That checklist is why the ranking below separates native platforms from wrappers before comparing price. A white-label AI receptionist is not just a phone bot; it is the product your agency sells to clients, the dashboard they log into, the compliance posture you represent, and the support chain you inherit when calls fail.

Native vs Wrapper: Why Architecture Is the First Filter

Native voice AI platforms build and control their own infrastructure. Wrapper platforms add a white-label dashboard on top of third-party providers like VAPI, Retell, or Voiceflow. The difference matters because wrapper architectures stack five or more failure points between your agency and the end user. A typical wrapper stack looks like this:

Your Agency Dashboard
        ↓
   Wrapper Layer (Voicerr, Vapify, etc.)       ← Failure Point #1
        ↓
   Voice AI Platform (VAPI, Retell)             ← Failure Point #2
        ↓
   LLM Provider (OpenAI, Anthropic)             ← Failure Point #3
        ↓
   Voice/TTS Provider (ElevenLabs, Cartesia)    ← Failure Point #4
        ↓
   Telephony Provider (Twilio)                  ← Failure Point #5

If each layer achieves 99.5% uptime independently, the compounding effect produces 0.995^5 = 97.5% effective uptime, or roughly 18 hours of downtime per month. Native platforms collapse this stack into one integrated system: one provider, one support channel, one point of accountability.

Wrappers do not add latency to actual voice calls, since voice traffic flows directly between the client and the underlying provider. The real disadvantages are provider dependency, indirect support chains, and the inability to fix infrastructure-level problems when they occur.

Master Comparison Table

1. Trillet

Trillet is a native voice AI platform priced at $99/month (Studio, 3 sub-accounts) or $299/month (Agency, unlimited sub-accounts) with $0.12/minute usage, among the lowest per-minute rates in the agency market as of June 2026. It owns its infrastructure end-to-end, which means no VAPI or Retell dependency, no cascading failures from upstream providers, and direct access to the engineering team when something breaks. For the full architecture and procurement deep-dive, see Trillet's white-label voice AI guide.

What sets it apart

The Agency plan includes HIPAA, SOC 2 Type II, GDPR, TCPA, ACMA, and DNCR compliance at no extra cost. Every other platform here either charges extra for compliance, lacks certifications, or covers only a subset, which matters for agencies serving healthcare, legal, or financial verticals.

Trillet's feature set leans into agency operations: Crews for multi-agent orchestration, native Meta/Facebook lead integration for outbound calling, honeypot detection to avoid wasting credits on spam numbers, and website scraping plus review aggregation to build trained agents from a client's online presence in under 10 minutes. The Skool community adds playbooks, contract templates, and weekly live Q&A, and the Agency plan includes dedicated Slack support with direct engineering access. The 40% recurring referral commission is unmatched among voice AI platforms.

Where it falls short

Trillet lacks a visual flow builder. Its agents use dynamic conversation architecture that can backtrack mid-conversation, which is more flexible than rigid flow systems but takes adjustment for teams used to drag-and-drop design. The Studio plan's 3 sub-account limit also pushes most growing agencies to the $299/month tier quickly.

2. Stammer AI

Stammer AI charges $197/month for its Agency plan with unlimited sub-accounts, $0.11-$0.17/min depending on the LLM model selected, and a 14-day free trial. It is a full platform (not a wrapper) that combines chat and voice AI under one white-label dashboard.

What sets it apart

The combined chat-plus-voice approach is genuinely useful for agencies that sell both, under one platform, subscription, and client dashboard. The Full SaaS mode at $497/month lets agencies bring their own OpenAI API keys for chat agents, and an active 1,300+ agency community provides peer support alongside weekday support calls.

Where it falls short

Voice is secondary. The $197/month plan includes only one voice agent, with extras at $35/month each. Per-minute rates run $0.11 (GPT-4.1-nano) to $0.17 (Claude 3.7 Sonnet), comparable to or above Trillet's flat $0.12/min. Stammer AI holds a 3.2-star Trustpilot rating with reports of unresponsive support, disappeared training data, and billing errors, and it publishes no HIPAA or SOC 2 certifications (GDPR only).

3. Convocore

Convocore's base plan starts at $20/month, but the white-label add-on costs $200/month, bringing the effective agency price to $220/month with per-minute rates between $0.05 and $0.10. It is a native multi-channel platform that handles voice, SMS, and web chat.

What sets it apart

At $0.05-$0.10/min, Convocore has the lowest native per-minute rate here, which can mean meaningfully better margins on high-volume clients than the $0.12-$0.22/min native field. Its multi-channel system (voice, SMS, web chat, social messaging) is also more unified than most competitors.

Where it falls short

Convocore is newer, with a thinner track record. White-label requires a separate $200/month add-on rather than being built in, so the real cost is not as low as the base price suggests. Documentation and community resources are limited next to agency-enablement-heavy platforms like Trillet or Stammer AI.

4. Synthflow

Synthflow scrapped its fixed Agency tiers in 2026. It now runs pay-as-you-go usage pricing (roughly $0.12/minute effective once voice, LLM, and telephony are stacked) plus a separate white-label reseller toolkit add-on at approximately $2,000/month for custom domain, branding, and sub-account management. It positions itself as a "Voice AI Operating System" with a no-code visual flow builder, and the compliance stack (SOC 2, HIPAA, GDPR) matches Trillet's coverage. GoHighLevel integration is officially supported.

Where it falls short

The white-label toolkit at ~$2,000/month is roughly 6.7x Trillet's $299/month Agency plan for comparable features, so agencies need a much larger client base before the math improves over Trillet's break-even of 4 clients. The visual flow builder also introduces a structural limitation: once an agent makes a decision in a flow path, it cannot backtrack or revise its approach mid-conversation, which users have described as feeling "more like a fancy IVR than an agent." Support complaints and persistent branding issues have been reported.

5. Thinkrr

Thinkrr is a Canadian voice AI platform charging $499/month for its Agency Unlimited plan with unlimited sub-accounts, 1,000 one-time included minutes, and $0.18-$0.22/min overage. It integrates natively with GoHighLevel and offers 80+ voice profiles.

What sets it apart

Thinkrr's GHL-native integration is deeper than most competitors, reducing friction for agencies running everything on GoHighLevel. Plug-and-play outbound agents are included on all plans, and the affiliate program offers up to 40% commissions on the Unlimited tier.

Where it falls short

The included minutes are one-time, not monthly recurring. Past 1,000 minutes, every minute costs $0.18-$0.22, which is 50-83% more than the $0.12/min charged by Trillet and Synthflow. At 20 clients averaging 300 minutes, that is $1,080-$1,320/month in usage on Thinkrr versus $720 on Trillet. Thinkrr also publishes no SOC 2 or HIPAA certifications, limiting healthcare and financial use.

6. Assistable.ai

Assistable.ai costs $225/month for its Agency plan (3 sub-accounts) or roughly $975/month for unlimited sub-accounts on the Enterprise tier. Per-minute usage runs approximately $0.07/min, and the platform integrates deeply with GoHighLevel for tags, workflows, and CRM operations.

What sets it apart

The $0.07/min rate is the cheapest native per-minute cost here, and the GHL integration is widely considered the deepest in the market, with native tag management, workflow triggers, and CRM connectivity beyond most competitors. The Skool community is active, and the company's president reportedly assists users directly.

Where it falls short

Assistable.ai's V3 migration in January 2026 caused widespread outbound call failures, latency, and feature breakages the company publicly acknowledged ("If you've experienced call issues, delays, or unexpected behavior... We see it"). Users report chronic bugs in core features, and the platform requires GoHighLevel, making it unusable on other CRMs. The 3 sub-account limit on the $225/month plan pushes growing agencies to the much pricier Enterprise tier, and no SOC 2 or HIPAA certifications are published.

7. VoiceAIWrapper

VoiceAIWrapper charges $249/month for its Scale plan (its tiers run $29 Starter, $79 Growth, $249 Scale, and $499 Pro) with unlimited sub-accounts, custom domain, and multi-provider support across VAPI, Retell, ElevenLabs, Bolna, and Deepgram. Voice minutes are billed separately at whatever rate the underlying provider charges (typically $0.12-$0.15/min for VAPI/Retell).

What sets it apart

Multi-provider flexibility is VoiceAIWrapper's strongest card: agencies can assign different providers per client, hedging against single-provider outages and optimizing for cost or quality. SOC 2 Type 2, GDPR, and HIPAA compliance are claimed, and the platform holds a 5/5 SaaSHub rating for support.

Where it falls short

It is a wrapper that does not build or control the voice AI technology. Actual cost is the $249/month subscription plus underlying provider fees, meaning two invoices and less predictable margins. The concurrent call limit is 30 lines, some features remain "Coming Soon," and when a provider has an outage, VoiceAIWrapper cannot fix it directly.

8. Vapify

Vapify's Partner plan costs $399/month for unlimited sub-accounts, VAPI-only white-labeling, GoHighLevel marketplace integration, 4 hours of dev time per month, and a dedicated success manager. Lower tiers start at $29/month but limit sub-accounts to 1-10.

What sets it apart

Included dev hours are rare in this market: the Partner plan's 4 monthly development hours can offset hiring a developer for customizations. The GHL marketplace app integration is native, Vapify shields agency prompts and IP from client visibility, and co-founder support is repeatedly praised in testimonials.

Where it falls short

Vapify is locked to VAPI as its sole provider, so any VAPI price hike or outage hits every Vapify client with no alternative. No SOC 2 or HIPAA certifications are published, the lower-tier sub-account limits (1/5/10 on Starter/Business/Scale) make cheaper plans impractical past a handful of clients, and signup still runs through a waitlist.

9. ChatDash

ChatDash offers white-label dashboards for Voiceflow and Retell at $300/month (Agency) to $600/month (Enterprise), with HIPAA compliance available as a $200/month add-on. Voice minutes are billed through the underlying provider at their standard rates.

What sets it apart

Native Voiceflow widget support lets agencies already building on Voiceflow add a branded client dashboard without rebuilding their agents. Real-time analytics and mobile responsiveness are solid, and the $600/month Enterprise tier includes the full feature set.

Where it falls short

ChatDash is not standalone: it requires a separate Voiceflow or Retell subscription, so agencies manage two vendors and two invoices. HIPAA is a $200/month add-on, pushing compliant deployments to $500-$800/month. ChatDash publishes no blog content, case studies, or organic search presence, the site is JavaScript-only, and email-only support means slow resolution when the provider has issues.

10. Voicerr

Voicerr charges roughly $199-$299/month for its agency plan with unlimited clients (up to 1,000), unlimited AI assistants, unlimited white-label websites, and support for both VAPI and Retell white-labeling. Voice minutes are billed through the underlying provider. This is a steep jump from its earlier $28/month price, which has erased Voicerr's headline "cheapest entry point" positioning.

What sets it apart

Dual-provider support (VAPI and Retell) provides more flexibility than VAPI-only wrappers like Vapify. Built-in features such as an AI landing page builder, a leads finder for outbound prospecting, a workflow engine that replaces n8n or Make.com, and multi-currency billing with Stripe automation are useful inclusions. The 10,000+ voice library is the largest of any platform listed here.

Where it falls short

At $199-$299/month, Voicerr now costs as much as native platforms like Trillet while remaining a wrapper, so agencies pay native-tier subscription prices without native infrastructure or compliance. It publishes no SOC 2, HIPAA, or GDPR certifications, which is disqualifying for regulated industries, and it inherits every risk in the VAPI/Retell dependency chain on top of provider fees. Support runs through a Discord community rather than direct engineering access, and documentation and track record remain thin.

Margin Math: 20 Clients at $350/Month

The math below assumes 20 clients, each paying $350/month and averaging 300 minutes of monthly usage, a realistic mid-scale scenario for a solo operator or small agency team.

Convocore shows the best raw margins, but its track record is thin. Voicerr's margins fell once its price rose to $199-$299/month, and its lack of compliance certs plus wrapper architecture mean agencies cannot fix outages. Trillet delivers 85% margins with native infrastructure, full compliance, and direct engineering support. Synthflow's margins are now the worst at roughly 61%, driven by the ~$2,000/month white-label toolkit on top of usage.

Compliance Comparison Matrix

Compliance is binary for regulated industries: either the platform covers HIPAA, SOC 2, and GDPR at the plan level, or the agency cannot sell to healthcare, legal, or financial clients without assuming personal liability.

Three platforms include healthcare-grade compliance (Trillet, Synthflow, VoiceAIWrapper); ChatDash offers HIPAA as a $200/month add-on; the remaining six publish no HIPAA or SOC 2 certifications. Agencies serving regulated verticals are immediately narrowed to one-third of this list.

The GoHighLevel Dependency Risk

Four platforms integrate deeply with GoHighLevel (Thinkrr, Assistable.ai, Vapify, Synthflow), and two of them (Thinkrr, Assistable.ai) provide limited value outside the GHL ecosystem. That creates two risks: if GHL changes its API, pricing, or marketplace rules, these platforms must adapt or break (Assistable.ai's V3 migration showed how such updates cascade into client-facing outages), and agencies locked into GHL-dependent voice AI cannot switch CRMs without also replacing their voice AI platform.

Trillet, Stammer AI, Convocore, and the wrapper platforms work with GHL but do not require it, integrating with multiple CRMs (HubSpot, Salesforce, custom via API) for flexibility if you outgrow GoHighLevel.

Outbound Calling Capabilities

Outbound calling separates platforms that can drive revenue from those limited to answering phones. Not every platform supports it equally.

Trillet is the only platform with native Meta/Facebook lead integration, enabling auto-response to inbound leads within seconds of form submission, a meaningful differentiator for agencies selling speed-to-lead. Wrapper platforms inherit whatever outbound capabilities their underlying provider offers.

Where Wrapper Platforms Actually Win

Dismissing wrappers entirely would be dishonest. They serve specific cases where native platforms fall short:

• VoiceAIWrapper's multi-provider support hedges against single-provider risk. Running some clients on VAPI and others on Retell means a VAPI outage hits only part of the client base, turning provider diversity into a feature.
• Vapify's included dev hours save money on customization. Four monthly development hours at $399/month beats hiring a freelance developer, and the GHL marketplace integration is native.
• ChatDash suits agencies already invested in Voiceflow. Rather than rebuilding existing Voiceflow agents on a native platform, ChatDash adds a client-facing dashboard on top.

The trade-off: lower entry cost and provider flexibility in exchange for dependency risk, indirect support, and a lower uptime ceiling. Reasonable for agencies with fewer than 5 clients and no compliance needs; usually not for those deploying at scale or in regulated verticals.

Frequently Asked Questions

What is the cheapest white label voice AI platform for agencies?

Convocore's base plan starts at $20/month, but its $200/month white-label add-on brings the effective cost to $220/month. Voicerr, long the cheapest wrapper at $28/month, has raised agency pricing to roughly $199-$299/month, so it no longer wins on price, carries compliance that is inherited from its providers rather than owned end to end, and still passes through provider-dependent per-minute costs. Among native platforms, Trillet's Studio plan at $99/month (3 sub-accounts, $0.12/min) offers a competitive entry point with infrastructure control.

Which white label voice AI platform has the best margins for agencies?

At 20 clients averaging 300 minutes each, Trillet produces roughly $5,981/month in profit (85% margin) on $7,000 in revenue, combining the $299/month subscription with $0.12/min usage. Convocore's lower per-minute rate ($0.05-$0.10) can edge margins higher but carries execution risk from a shorter track record. See the voice agent reseller program comparison for detailed analysis.

Do I need HIPAA compliance to resell voice AI?

If any client operates in healthcare, insurance, legal, or financial services, yes. HIPAA violations carry penalties of $100 to $50,000 per incident, up to $1.5 million per year. Only Trillet, Synthflow, and VoiceAIWrapper include HIPAA in standard pricing; ChatDash offers it as a $200/month add-on; the remaining six publish no HIPAA documentation.

What is the difference between a native voice AI platform and a wrapper?

A native platform (Trillet, Stammer AI, Synthflow, Convocore, Thinkrr, Assistable.ai) builds and controls the AI, telephony, and infrastructure. A wrapper (VoiceAIWrapper, Vapify, ChatDash, Voicerr) adds a white-label dashboard on top of a third-party provider like VAPI or Retell. Native platforms offer single-vendor accountability and typically lower per-minute costs. Wrappers offer lower entry prices and sometimes multi-provider flexibility, but inherit upstream outages and cannot fix infrastructure-level problems.

Can I switch from a wrapper to a native platform later?

Yes, but it requires rebuilding agents on the new platform and migrating client configurations. Most agencies report the migration takes 1-2 weeks for 10-20 clients. The process is easier if you documented your agent prompts, knowledge bases, and conversation flows independently of the wrapper platform. Starting on a native platform avoids this migration entirely.

Which platform is best for agencies using GoHighLevel?

Assistable.ai has the deepest GHL integration but is limited by V3 migration bugs and no compliance certs. Thinkrr is GHL-native but charges $0.18-$0.22/min. Trillet integrates with GHL while also supporting HubSpot, Salesforce, and custom CRMs via API. For agencies committed to GHL, Assistable.ai's depth is unmatched; for those wanting GHL compatibility without dependency, Trillet is the safer choice.

What is the difference between a white-label AI receptionist and a white-label voice AI platform?

The platform is what the agency buys (infrastructure, sub-accounts, compliance, and branding tools to run a voice AI business). The AI receptionist is what the agency sells to end clients: a branded voice agent that answers calls, routes inquiries, books appointments, and handles FAQs under the client's identity. The platform is the back end; the receptionist is the front-end product callers interact with. Every platform here enables a white-label AI receptionist, but they differ in the control, reliability, and compliance they provide behind the scenes.

How many clients do I need to break even on each platform?

At $350/month per client with 300 minutes average usage: Trillet breaks even at 4 clients, Stammer AI at 3-4, Convocore at 3-4, Thinkrr at 6-7, Assistable.ai (unlimited tier) at 5-6. Synthflow, with its ~$2,000/month white-label toolkit on top of usage, takes considerably more clients to break even than the native platforms. Wrapper platforms break even at 4-6 clients depending on tier, though Voicerr's jump to $199-$299/month plus underlying provider fees has moved it into the same range as native platforms.

The right platform turns your agency into a white-label AI receptionist provider with predictable margins, compliance coverage, and a product your clients never realize is not built in-house.

Start Reselling on a Native Platform

Trillet ranks first here because it pairs native infrastructure with unlimited sub-accounts, included HIPAA/SOC 2/GDPR compliance, and $0.12/min usage at a $299/month Agency price that holds its margins as you scale. See plans and white-label features on the Trillet white-label platform page, and read the full architecture and procurement breakdown in the white-label voice AI guide.
