Top 10 White Label Voice AI Platforms for Agencies in 2026

As of April 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, $0.09/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 ($1,400/month Agency, $0.12/min, 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 ($28/month, VAPI/Retell wrapper, 10,000+ voice library, no compliance certs).

The native-vs-wrapper distinction is the single most important factor agencies overlook during evaluation. A wrapper that costs $28/month can end up more expensive and less reliable than a $299/month 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 $0.09/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: Voicerr at $28/month is defensible for solo operators testing the market before committing to a native platform, and VoiceAIWrapper's multi-provider flexibility lets agencies avoid single-provider lock-in.

• Biggest price-to-value gap: Synthflow's $1,400/month Agency plan charges 4.7x more than Trillet for comparable white-label features. The no-code flow builder is good, but not $1,100/month better.

Evaluation Criteria

Six factors separate a viable agency platform from an expensive mistake: architecture type (native vs wrapper), per-minute cost, sub-account limits, compliance coverage, white-label completeness, and support model. Architecture determines your uptime ceiling and support chain. Per-minute cost determines your margins at scale. Sub-account limits determine when you hit a paywall. Compliance determines which verticals you can serve. White-label completeness determines whether your clients ever see the underlying vendor. And support model determines how fast you recover when something breaks.

Every platform in this roundup was evaluated against all six. The rankings weight architecture and per-minute cost most heavily because those two factors compound over time in ways that monthly subscription price does not.

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:

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 a single integrated system, which means one provider, one support channel, and one point of accountability.

Wrappers do not add latency to actual voice calls. Voice traffic flows directly between the client and the underlying provider without passing through the wrapper's servers. 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 $0.09/minute usage, the lowest per-minute rate in the agency market as of April 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.

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 on this list either charges extra for compliance, lacks certifications entirely, or covers only a subset. For agencies serving healthcare, legal, or financial verticals, this is not optional.

Trillet's feature set leans heavily into agency operations: Crews for multi-agent orchestration, native Meta/Facebook lead integration for outbound calling, honeypot detection to prevent wasted credits on spam numbers, and website scraping combined with review aggregation to build trained agents from a client's online presence in under 10 minutes. The Skool community includes playbooks, contract templates, and weekly live Q&A sessions. The Agency plan adds dedicated Slack support with direct access to engineering.

The 40% recurring referral commission program is unique. No other voice AI platform offers an agency-to-agency referral structure with that payout.

Where it falls short

Trillet lacks a visual flow builder. Agents use dynamic conversation architecture that can backtrack mid-conversation, which is more flexible than rigid flow-based systems, but agencies accustomed to drag-and-drop conversation design will need to adjust. The Studio plan's 3 sub-account limit also means most growing agencies will move 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. One platform, one subscription, one client dashboard. The Full SaaS mode at $497/month lets agencies bring their own OpenAI API keys for chat agents, which offers cost control at scale. An active community of 1,300+ agencies provides peer support alongside daily support calls Monday through Friday.

Where it falls short

Voice is secondary. The $197/month plan includes only one voice agent, with additional voice agents costing $35/month each. Per-minute rates range from $0.11 (GPT-4.1-nano) to $0.17 (Claude 3.7 Sonnet), which is 22-89% more expensive than Trillet's flat $0.09/min. Stammer AI holds a 3.2-star rating on Trustpilot with reports of unresponsive support, disappeared training data, and billing errors. It is GDPR compliant but does not publish HIPAA or SOC 2 certifications.

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

The per-minute rate is the lowest on this list for a native platform. At $0.05-$0.10/min, agencies running high-volume clients could see meaningfully better margins than the $0.09-$0.22/min range offered by the rest of the native field. The multi-channel approach is also more comprehensive than most competitors, covering voice, SMS, web chat, and social messaging in a unified system.

Where it falls short

Convocore is a newer platform with a thinner track record than established competitors. The white-label capability requires a separate $200/month add-on rather than being built into the base product, which means the actual white-label cost is not as cheap as the base price suggests. Documentation and community resources are limited compared to platforms like Trillet or Stammer AI that have invested heavily in agency enablement.

4. Synthflow

Synthflow's Agency plan costs $1,400/month (recently increased from $1,250) and includes 6,000 minutes, 80 concurrent calls, unlimited sub-accounts, and SOC 2/HIPAA/GDPR compliance. Overage runs $0.12/minute. It positions itself as a "Voice AI Operating System" with a no-code visual flow builder.

What sets it apart

The no-code flow builder is Synthflow's primary differentiator. Agencies can design conversation paths visually with drag-and-drop nodes, which makes complex branching logic more accessible to non-technical teams. The 80 concurrent call limit is generous for high-volume operations, and the compliance stack (SOC 2, HIPAA, GDPR) matches Trillet's coverage. GoHighLevel integration is officially supported.

Where it falls short

The price. At $1,400/month, Synthflow costs 4.7x more than Trillet's $299/month Agency plan for comparable white-label features. Agencies need to sign 12+ clients before the math improves over Trillet's break-even point 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. Users have described the experience as feeling "more like a fancy IVR than an agent." Support complaints on lower tiers 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. For agencies already running their entire operation on GoHighLevel, the tight coupling reduces friction. 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. Once you burn through 1,000 minutes, every subsequent minute costs $0.18-$0.22, which is double Trillet's $0.09/min and 50% more than Synthflow's $0.12/min. At scale, this cost difference is substantial. An agency with 20 clients averaging 300 minutes each would pay $1,080-$1,320/month in usage on Thinkrr versus $540/month on Trillet. Thinkrr publishes no SOC 2 or HIPAA certifications, limiting its viability in healthcare and financial verticals.

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 per-minute cost among native platforms on this list. The GHL integration is widely considered the deepest in the market, with native tag management, workflow triggers, and CRM connectivity that goes beyond what most competitors offer. 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 issues, and feature breakages that the company acknowledged publicly. Their official statement read: "If you've experienced call issues, delays, or unexpected behavior, we want to be clear from the start: We see it." Users report chronic bugs affecting core features, and the platform requires GoHighLevel, making it unusable for agencies on other CRMs. The sub-account limit of 3 on the $225/month plan pushes growing agencies to the significantly more expensive Enterprise tier. No SOC 2 or HIPAA certifications are published.

7. VoiceAIWrapper

VoiceAIWrapper charges $299/month for its Growth plan 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 configure different underlying providers for different clients, which hedges against single-provider outages and lets agencies optimize for cost or quality per client. SOC 2 Type 2, GDPR, and HIPAA compliance are claimed. The platform holds a 5/5 rating on SaaSHub for support quality.

Where it falls short

It is a wrapper. VoiceAIWrapper does not build or control the voice AI technology. The agency's actual cost is the $299/month subscription plus whatever the underlying provider charges, which means two invoices and less predictable margins. The concurrent call limit is 30 lines maximum. Some features remain listed as "Coming Soon." And when an underlying 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 hours of monthly development time can offset the cost for agencies that would otherwise hire a developer for customizations. The GHL marketplace app integration is native, and Vapify protects agency prompts and IP from client visibility. Co-founder support is repeatedly praised in testimonials.

Where it falls short

Vapify is locked to VAPI as its sole provider. If VAPI raises prices, Vapify agencies absorb the increase with no alternative. If VAPI goes down, every Vapify client goes down. No SOC 2 or HIPAA certifications are published. The sub-account limits on lower tiers (1 on Starter, 5 on Business, 10 on Scale) make the cheaper plans impractical for agencies managing more than a handful of clients. The platform still uses a waitlist-based signup process.

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 means agencies already building on Voiceflow can add a branded client-facing dashboard without rebuilding their agent architecture. Real-time analytics dashboards and mobile responsiveness are solid. The Enterprise tier at $600/month includes the full feature set.

Where it falls short

ChatDash is not a standalone platform. It requires a separate Voiceflow or Retell subscription, meaning agencies manage two vendors and two invoices. HIPAA compliance is a $200/month add-on, which brings the effective cost to $500-$800/month for compliant deployments. ChatDash publishes no blog content, no case studies, and no organic search presence. The site is JavaScript-only, which raises questions about technical maturity. Email-only support means slow resolution when the underlying provider has issues.

10. Voicerr

Voicerr charges $28/month for its Pro 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.

What sets it apart

The price. At $28/month, Voicerr is the cheapest entry point on this list by a wide margin. The dual-provider support (VAPI and Retell) provides more flexibility than VAPI-only wrappers like Vapify. Built-in features like 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 generous for the price point. The 10,000+ voice library is the largest of any platform listed here.

Where it falls short

Voicerr publishes no SOC 2, HIPAA, or GDPR certifications. For agencies serving regulated industries, this is disqualifying. As a wrapper, it inherits every risk in the VAPI/Retell dependency chain. Support runs through a Discord community, which means other users guessing at your problem rather than engineers fixing it. Documentation is limited, and the platform's track record is shorter than established competitors. The $28/month price also means Voicerr is likely a small team, which raises longevity questions.

Margin Math: 20 Clients at $350/Month

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

Convocore and Voicerr show the best raw margins, but with important caveats. Convocore's track record is thin. Voicerr's lack of compliance certs excludes regulated verticals, and its wrapper architecture means agencies cannot fix outages. Trillet delivers 88% margins with native infrastructure, full compliance, and direct engineering support. Synthflow's margins are the worst at 70%, entirely because of the $1,400/month subscription.

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, and VoiceAIWrapper. ChatDash offers HIPAA as a $200/month add-on. The remaining six platforms publish no HIPAA or SOC 2 certifications, which means agencies serving regulated verticals are immediately narrowed to one-third of this list.

The GoHighLevel Dependency Risk

Four platforms on this list integrate deeply with GoHighLevel: Thinkrr, Assistable.ai, Vapify, and Synthflow. Two of them (Thinkrr and Assistable.ai) are essentially GHL-dependent, meaning they provide limited or no value outside the GoHighLevel ecosystem.

This creates two risks for agencies. First, if GHL changes its API, pricing, or marketplace rules, these platforms must adapt or break. Assistable.ai's V3 migration issues in January 2026 demonstrated how platform updates can cascade into client-facing outages. Second, agencies locked into GHL-dependent voice AI cannot migrate to another CRM without also replacing their voice AI platform.

Trillet, Stammer AI, Convocore, and the wrapper platforms work with GHL but do not require it. They integrate with multiple CRMs (HubSpot, Salesforce, custom via API), which gives agencies flexibility if they outgrow or move away from GoHighLevel.

Outbound Calling Capabilities

Outbound calling separates platforms that can drive revenue from platforms limited to answering phones. Not every platform on this list supports outbound equally.

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

Where Wrapper Platforms Actually Win

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

Voicerr at $28/month is the cheapest way to test the agency model. An agency that is not sure whether voice AI reselling will work can validate the concept for less than a dinner out. If it works, migrating to a native platform is straightforward. If it doesn't, the sunk cost is minimal. This is a legitimate advantage over committing $299/month before signing a single client.

VoiceAIWrapper's multi-provider support hedges against single-provider risk. Agencies can run some clients on VAPI and others on Retell, which means a VAPI outage only affects a portion of the client base. Native platforms offer one provider (their own), which is a strength when that provider is reliable and a weakness if it isn't. VoiceAIWrapper turns provider diversity into a feature.

Vapify's included dev hours save money for agencies that need customization. Four hours of monthly development time at $399/month is cheaper than hiring a freelance developer, and the GHL marketplace integration is native rather than bolted on.

ChatDash makes sense for agencies already invested in Voiceflow. If an agency has spent months building Voiceflow agents, switching to a native platform means rebuilding everything. ChatDash lets them keep their existing agent architecture and add a client-facing dashboard on top.

The wrapper trade-off is clear: lower entry cost and provider flexibility in exchange for dependency risk, indirect support, and a lower uptime ceiling. For agencies with fewer than 5 clients and no compliance requirements, that trade-off can be reasonable. For agencies at scale or in regulated verticals, it usually is not.

Frequently Asked Questions

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

Voicerr at $28/month is the cheapest by subscription price, but it is a wrapper with no compliance certifications and provider-dependent per-minute costs. Among native platforms, Trillet's Studio plan at $99/month (3 sub-accounts, $0.09/min) offers the lowest entry point with infrastructure control. Convocore's base plan starts at $20/month, but the $200/month white-label add-on brings the effective cost to $220/month.

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

At 20 clients averaging 300 minutes each, Trillet produces approximately $6,161/month in profit (88% margin) on $7,000 in revenue, combining the $299/month subscription with $0.09/min usage. Convocore's lower per-minute rate ($0.05-$0.10) can push margins slightly higher, but the platform's shorter track record introduces execution risk. See the voice agent reseller program comparison for detailed margin analysis across platforms.

Do I need HIPAA compliance to resell voice AI?

If any of your clients operate in healthcare, insurance, legal, or financial services, yes. HIPAA violations carry penalties of $100 to $50,000 per incident with a maximum of $1.5 million per year. Only three platforms on this list include HIPAA in their standard pricing: Trillet, Synthflow, and VoiceAIWrapper. ChatDash offers it as a $200/month add-on. The remaining six platforms 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 its V3 migration bugs and lack of compliance certs limit its appeal. 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, which avoids GHL lock-in. For agencies committed to GHL, Assistable.ai's integration depth is unmatched. For agencies that want GHL compatibility without dependency, Trillet is the safer choice.

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, Synthflow at 9-10, Thinkrr at 6-7, Assistable.ai (unlimited tier) at 5-6. Wrapper platforms break even at 1-4 clients depending on tier, but their total cost includes underlying provider fees that reduce the gap.
