TL;DR – Compare AI Voice Reseller Platforms
Retell AI and ElevenLabs are strong AI layers for building voice agents and conversational experiences, and they offer partner programs.
But if you want to resell AI voice as a repeatable monthly service, you still need:
a telecom voice foundation (numbers, routing, call flows, reliability),
and a quote-to-cash layer for usage rating, invoicing, and telecom taxes.
Viirtue is built around that reseller reality: it bundles the Voice layer + ViiBE quote-to-cash + white-label workflows, then layers in AI Voice Agents and AI Insights you can actually package and sell.
AI voice is moving fast, but most AI voice reseller programs are still built for demos, not for selling. MSPs and agencies looking to monetize AI voice quickly run into the same problem: great AI models on one side, and a messy reality of telecom, billing, usage tracking, and taxes on the other.
This guide compares Viirtue vs Retell AI vs ElevenLabs through the lens that actually matters for resellers. Not which voice sounds the most human, but which platform lets you sell AI voice under your brand, bill it cleanly, protect margin, and scale without stitching together half a dozen tools.
If your goal is to turn AI voice into a repeatable monthly service, this comparison will help you choose the right stack from day one.
The big idea: AI voice is a stack, not a tool
Most “voice AI” comparisons focus on demos.
Resellers win or lose on operations.
To sell AI voice profitably at scale, you typically need four layers:
AI Layer: AI voice agents, knowledge, actions, monitoring, summaries, analytics.
Voice Layer (Telecom Foundation): Real phone numbers, routing, queues, call flows, PBX or SIP foundation, and uptime.
Monetization Layer (Quote-to-Cash): Product catalog, quoting, usage rating, invoicing, payments, lifecycle changes.
Compliance Layer (Telecom Taxes + Auditability): Telecom tax automation, usage defensibility, jurisdiction handling, and clean invoicing.
Viirtue’s own reseller guidance calls out the need for these layers in one place if you want to avoid “stitching together vendors.”
Option 1: Resell Retell AI or ElevenLabs (AI layer first)
Retell AI and ElevenLabs can be excellent choices when you want a best-in-class AI layer. The key is understanding what you still have to bring along with it.
Retell AI: a voice agent platform that integrates with telephony
Retell describes itself as a solution for building conversational AI agents for phone calls, supporting inbound and outbound calls, and integrating with telephony providers.
They also have a partner program aimed at agencies and developers building end-to-end voice agents with their platform.
What this typically means for resellers:
Retell can cover a lot of the agent-building workflow, but your reseller business still needs a telecom foundation, plus billing, taxes, packaging, and a customer portal experience if you want this to feel like a real product line.
If you are evaluating unit economics, Retell publicly lists usage-based pricing for AI voice agents (minute-based).
ElevenLabs: voice generation plus an agents platform
ElevenLabs positions its Agents Platform as tooling to build, launch, and scale agents, supported by expressive voice models and monitoring/evaluation tools.
Their AI voice agents messaging includes inbound and outbound use cases, and even references scaling outbound with Twilio or SIP trunking, which reinforces the point that telephony is still a key part of the real-world stack.
What this typically means for resellers:
ElevenLabs can be powerful for voice quality and agent experiences, but you still need the Voice layer and the quote-to-cash layer if your goal is to resell AI voice to SMBs with clean invoicing, taxes, and repeatable onboarding.
Option 2: Resell AI Voice the MSP way: Viirtue’s full-stack platform
Viirtue is built around a simple premise: resellers need more than an AI demo.
Viirtue’s own AI voice reseller guidance explicitly calls out that resellers need the Voice AI layer plus the telecom foundation, billing automation, and partner-ready assets.
1) AI Voice Agents you can white-label and package
Viirtue’s AI Voice Agents are designed to be native to its Cloud PBX and to plug into existing numbers, queues, and call flows.
They are also described as:
trained per client (upload FAQs, SOPs, policies, catalogs),
able to do real work (routing, scheduling, ticket creation),
designed for packaging and compliance.
2) AI Insights (formerly “sentiment analysis”), you can sell as an add-on
If you used to sell “sentiment analysis,” you can now position it more broadly as AI Insights, including:
call transcription,
AI summaries,
sentiment indicators and flags,
faster QA and coaching workflows.
Viirtue’s sentiment analysis is integrated into the VoIP platform, with summaries and real-time sentiment indicators.
3) The ViiBE layer: quote-to-cash for the reseller reality
This is the part most AI-first stacks ignore.
ViiBE is described by Viirtue as a proprietary platform connecting the reseller workflow end-to-end: catalog, quote, tax, usage rating, e-sign, payment, provisioning, invoicing, and lifecycle management (included for partners at no additional software license cost).
ViiBE also highlights practical capabilities like fast quoting and automatic invoicing within one platform.
4) Usage rating + telecom tax automation: the unglamorous part that protects margin
If you are reselling voice AI, you are almost always dealing with:
monthly recurring,
plus usage-based charges,
plus taxes and telecom fees.
Viirtue positions Usage Rating as automated within ViiBE.
And Tax Automation handles telecom tax calculation, so you can invoice and get paid without manual tax work.
5) Go-to-market assets: templates that make selling faster
Viirtue highlights marketing templates that partners can brand and use to sell more efficiently.
The simplest way to think about the comparison
Viirtue covers the layers resellers need
AI Voice Agents + AI Insights you can package and resell.
Telecom foundation so calls route reliably with real numbers and call flows (as outlined in Viirtue’s reseller guidance).
ViiBE quote-to-cash plus automated usage rating and taxes.
White-label and MSP positioning (Viirtue states it serves MSPs and does not work with the end user).
Retell AI and ElevenLabs are primarily AI layers
Retell: voice agent platform with telephony integrations, testing/monitoring, plus partner program.
ElevenLabs: agents platform + voice agents, references working with SIP trunking and Twilio.
They can be a great fit, but most resellers still need to solve the Voice layer and the quote-to-cash layer somewhere else.
Capability MSPs typically need | Viirtue | Retell AI | ElevenLabs |
|---|---|---|---|
White-label reseller workflow (brand-first) | Yes (built for MSP partners) | Partner program, but reseller ops vary | Partner programs exist, reseller ops vary |
Telecom voice foundation (numbers, routing, call flows) | Yes (telecom foundation called out in reseller guidance) | Integrates with telephony providers | Works with SIP trunking/Twilio use cases |
Quote-to-cash platform | ViiBE (catalog → quote → e-sign → invoice, etc.) | Not positioned as quote-to-cash | Not positioned as quote-to-cash |
Usage rating automation | Yes | Usage pricing exists, billing layer is separate | Usage pricing exists, billing layer is separate |
Telecom tax automation | Yes | Typically separate | Typically separate |
AI voice agents | Yes | Yes | Yes |
AI Insights (summaries + sentiment-style signals) | Yes | Platform analytics exist, but “AI insights” packaging is on you | Analytics messaging exists, packaging is on you |
Partner go-to-market templates | Yes | Varies | Varies |
A reseller-friendly way to package AI voice (without custom projects)
If you want to scale this as a monthly service, avoid “we can build anything” offers.
Start with 3 productized SKUs:
AI Receptionist: Answer every call, capture intent, route correctly, and book next steps.
After-Hours and Overflow Coverage: Eliminate missed calls, reduce voicemails, and keep a clean handoff.
Lead Qualification and Appointment Setting: Convert inbound intent into booked appointments, with follow-ups.
Then sell AI Insights as a high-margin add-on:
call summaries,
sentiment flags,
searchable transcripts,
coaching and QA workflows.
Viirtue’s AI voice agent content and reseller guidance both align to this kind of repeatable “outcomes first” packaging.
When Retell AI or ElevenLabs might be the better fit
This is not a “one is good, one is bad” situation.
Choose an AI-first platform first if:
you already have telecom and billing handled,
you are building a single internal agent for one org,
you have an engineering-heavy team, and you want maximum control of the AI layer,
you are comfortable assembling partner tooling around it.
Retell explicitly emphasizes the build/test/deploy/monitor lifecycle for voice agents and telephony integrations.
ElevenLabs emphasizes voice-rich models and tooling to build and scale agents.
When Viirtue is the cleaner path
Choose Viirtue when your goal is to resell AI voice at scale:
you want a telecom foundation + AI layer + quote-to-cash in one stack,
you want white-label workflows and a partner model designed for MSPs,
you want usage rating and telecom tax handling to be part of the system, not a spreadsheet.
Viirtue’s AI voice reseller guidance is explicit: resellers scale best when they are not stitching together vendors, and when billing automation and the telecom foundation are included.
Final Thoughts on Becoming an AI Voice Reseller
When it comes to AI voice reseller programs, the difference between experimenting and actually scaling comes down to the stack behind the AI. Retell AI and ElevenLabs offer powerful tools for building voice agents, but most MSPs still need to solve the telecom foundation, usage-based billing, and tax complexity on their own.
Viirtue takes a different approach. By combining AI Voice Agents, AI Insights, a native telecom voice layer, and the ViiBE quote-to-cash platform, it gives resellers a way to package, price, bill, and support AI voice as a real monthly service, not a custom project.
For MSPs who want to protect margin, simplify operations, and launch faster under their own brand, a full-stack platform purpose-built for resale is often the cleaner path.
If your goal is to turn AI voice into a repeatable revenue stream, not just a technical capability, choosing the right reseller platform from the start matters more than picking the flashiest demo.
FAQ: Becoming an AI Voice Reseller
What is an AI voice reseller platform?
An AI voice reseller platform is a stack that lets you sell AI voice agents under your brand while handling the telecom foundation (calls, numbers, routing) and the monetization layer (quoting, usage rating, billing, taxes). Viirtue’s reseller guidance describes this as multiple required layers in one place to avoid stitching vendors together.
What are “AI Insights” in VoIP?
AI Insights are the post-call and in-call intelligence layers: transcription, summaries, and sentiment-style indicators that reveal what happened, what needs follow-up, and where conversations went sideways. Viirtue’s sentiment analysis page describes summaries, transcription, and sentiment indicators integrated into the VoIP platform.
What is ViiBE?
ViiBE is Viirtue’s quote-to-cash and orchestration platform that connects the reseller workflow from catalog and quoting through taxes, usage rating, payment, provisioning, invoicing, and lifecycle management.
Why does “usage rating” matter for AI voice agents?
Because AI voice is often usage-based (minutes, calls, summaries). If you cannot rate usage accurately, you cannot invoice confidently or protect margin. Viirtue describes usage rating as automatically calculated per billing cycle with payments charged at cycle end.
Why do telecom taxes matter for AI voice resale?
If your offer includes phone numbers, calling, and telecom services, taxes and surcharges can be complex and vary by jurisdiction. Viirtue positions ViiBE tax automation as handling those calculations so you can invoice and get paid.
Do Retell AI or ElevenLabs replace the telecom voice layer?
Retell’s docs describe telephony provider integrations for inbound and outbound calls. (Retell AI)
ElevenLabs references outbound scaling with Twilio or SIP trunking, which implies telephony still matters. (ElevenLabs)
In a reseller model, you still need a dependable voice foundation and a billing/tax layer somewhere in your stack.
What makes Viirtue different for MSPs?
Viirtue positions itself as MSP-focused and channel-first, stating it serves MSPs and does not work directly with end users.
It also bundles quote-to-cash (ViiBE) with usage rating and tax automation, plus AI Voice Agents and AI Insights that can be packaged and sold.
What is the fastest path to a sellable AI voice offer?
Start with one high-intent call workflow (like inbound call answering or scheduling), productize it into a repeatable SKU, and make sure your stack includes the telecom foundation plus quote-to-cash automation. That “full-stack reseller reality” is the framing Viirtue uses in its AI voice reseller guidance.
