How to White-Label Vapi Voice AI Agents for Client Delivery

Building the voice agent is hard. Making the prompts work, cutting down the latency, and letting the LLM handles edge cases you never thought to script takes time. You demo it to a client, and they’re blown away. But then even more questions start.

“Can I see the call logs?” “How many bookings did it make yesterday?” “Can we put our logo on this?” And the one that makes your stomach drop: “Just give me a login so I can check whenever I want.”

Suddenly you realize: Vapi gave you everything you needed to build the agent, but nothing you need to deliver it as a professional service. Vapi has no built-in white-labeling, no client sub-accounts, and no billing automation. The dashboard that works so well for you is overwhelming and dangerous for a client. One wrong click, and they’re reading your prompts, tweaking your LLM settings, or worse — accidentally deleting the agent you spent weeks perfecting.

This is the gap every voice AI agency hits at scale. The solution isn’t to build a custom frontend from scratch – agencies report spending months and months of development just to get basic client management working. The solution is a white-label client portal that wraps your Vapi agents in a branded, secure interface purpose-built for non-technical end users.

Here’s exactly how to do it.

Why the Native Vapi Dashboard Fails Your Clients

Before we get to the solution, let’s be precise about the problem. Vapi’s dashboard is excellent — for you, the builder. For your clients, it creates five specific roadblocks:

No White-Labeling

Your client sees the Vapi logo, not yours. It positions you as a reseller of someone else’s platform rather than a premium solutions provider.

A Developer-Focused Interface

Vapi’s canvas, prompt editor, and model selector are tools you love. They are also tools that a non-technical business owner should never touch. One wrong drag on the canvas, and a production agent stops working.

Manual Billing

There’s no way to automate client billing based on usage. You’re stuck in “Excel hell,” manually tracking minutes and chasing invoices. Worse: Vapi doesn’t expose billing details via API, so you can’t even build your own automated solution.

Limited Analytics

You can see raw call data, but proving the value your agent delivers — booked appointments, qualified leads, resolved tickets — requires custom reporting that Vapi doesn’t provide.

No Client Isolation

In a standard Vapi organization, multiple client agents sit side by side. There’s no way to give Client A access to only their data while keeping Client B’s information — and your master account — completely invisible.

Agencies that ignore these problems end up stuck: they can’t scale past a handful of clients because every new engagement adds another layer of manual reporting, billing reconciliation, and security anxiety.

What a Proper White-Label Vapi Portal Looks Like

The goal isn’t just to put a logo on Vapi. It’s to create a separate product experience — one where your clients feel like they’re using a custom-built SaaS platform, not a bridge to an open-source tool. Here’s what that requires:

1. Branded, Per-Client Workspaces

Each client gets a dedicated subdomain (or custom domain) with their logo, their brand colors, and their company name. When they log in, they see their portal — not a shared dashboard.

2. Scoped Access and Total Isolation

Under the hood, the portal uses Vapi’s API to filter every piece of data by client. Client A sees only their agents, their call logs, and their analytics. They have zero visibility into Client B’s data — or your master Vapi account.

This is the “no-touch” model: clients can listen to recordings, read transcripts, and view dashboards, but they cannot open the Vapi canvas, edit prompts, or change model settings. Your intellectual property stays protected.

3. Business-Ready Analytics

Raw call logs don’t help a business owner. A good portal translates Vapi’s execution data into dashboards that answer real questions: How many calls today? What was the booking rate? How many calls needed human escalation? Where are the failure hotspots?

4. Automated Billing with Stripe

The portal tracks usage per client, applies your markup, and handles recurring billing automatically. You set the pricing model — per-minute, per-call, monthly subscription plus overage, or flat retainer — and Stripe does the rest. No more spreadsheets.

How to White-Label Vapi: Three Paths

There are three ways to deliver a white-labeled Vapi experience. Each has different tradeoffs.

Option 1: Build It Yourself

You connect to Vapi’s API, build a frontend from scratch (or with an AI app generator), manage your own authentication layer, and integrate Stripe for billing. Full control, but full responsibility: you’ll spend months building and forever maintaining it.

Option 2: Use a Vapi-Specific Wrapper

Platforms like Vapify, Voicerr, and VoiceAIWrapper sit on top of Vapi and provide white-labeling, client management, and billing as a service. They range from $29 to $399 per month. Setup is fast — often under 30 minutes — but your business becomes dependent on the wrapper platform as well as Vapi. Every call still flows through Vapi’s infrastructure.

Option 3: Use the Five White-Label Portal

Five takes a different approach. Rather than being a thin wrapper, it’s a full-stack application platform that connects directly to Vapi’s API. You get a managed MySQL database, role-based authentication, Stripe billing, and a complete white-label Vapi portal, all under your domain and your brand. Because Five handles the infrastructure (database, authentication, hosting) and gives you full SQL and JavaScript access, you never hit a ceiling. You can even overcome Vapi’s data retention limits: call logs and recordings are stored in Five’s database, so you don’t need to worry about Vapi deleting your data. You can extend the portal as your needs grow.

Here’s how the three white-label Vapi options compare:

Feature	Build Your Own	Wrapper Platforms	Five Portal
Time to deploy	Months	30 minutes	Under 1 week
Custom branding	Full control	Limited	Full control
Client isolation	Custom build	Built-in	Built-in
Automated Stripe billing	Custom build	Built-in	Built-in
Custom analytics	Full control	Limited	Full SQL access
Infrastructure management	Your responsibility	Platform handles it	Five handles it
Dependency risk	Vapi only	Vapi + Wrapper	Vapi only
Extensibility	Unlimited	Limited	Unlimited (SQL, JS, TS)

Our bias is obvious — we built the Five portal. But the choice depends on your agency’s stage. If you’re just starting out with one or two clients, a wrapper might make sense. If you’re scaling past five clients and want to build a sustainable Voice-as-a-Service (VaaS) business with your own platform identity, a custom portal is the long-term play.

Step-by-Step: Delivering a White-Label Client Experience

Let’s walk through what the process looks like when you use a white-label portal. We’ll use Five as the example, but the principles apply regardless of your chosen path.

Step 1: Connect Your Vapi Account

Start by adding your Vapi API key. The portal automatically syncs all your assistants, phone numbers, and knowledge bases. No manual import is needed – your full Vapi configuration becomes available in the portal within minutes.

Step 2: Brand Your Platform

Upload your logo, set your brand colors, and configure your custom domain. Everything the client sees — from the login page to the analytics dashboard — carries your brand identity. There’s no mention of Vapi, no mention of the portal provider. Just your agency’s platform.

Step 3: Create Client Workspaces

For each client, you create a separate workspace with unique login credentials. You can support Signle Sign-On such as Google OAuth so clients log in with their existing business accounts — no new passwords to manage.

Step 4: Configure Client Access and Billing

Set your pricing model: per-minute, per-call, monthly subscription plus overage, or flat retainer. Connect your Stripe account, and billing runs automatically. You can mark up Vapi’s underlying costs however you want — and control whether clients even see cost-per-call data.

Step 5: Assign Permissions

Decide what each client sees. Typically, you’ll give them:

• Dashboard view: Total calls, success rate, average duration
• Call logs: Date, time, duration, outcome for every call
• Transcripts: Read-only access to conversation transcripts
• Recordings: Listen to call recordings for quality assurance

You’ll keep hidden: prompt configurations, LLM model settings, API keys, knowledge base contents, and anything else that’s your competitive advantage.

Step 6: Onboard the Client

Send your client their branded URL and credentials. They log in, see their company’s portal, and immediately understand what their voice agent is doing — without ever knowing Vapi exists.

This changes the conversation from “Trust me, the agent is working” to “Here’s exactly what the agent did yesterday.” It transforms you from a technical contractor into a platform provider — and that’s a position you can charge significantly more for.

Security: The API Key Problem and How to Solve It

There’s one security concern that deserves special attention: API key exposure. If you’re embedding a Vapi widget on a client’s website, your public API key is visible in the browser. This is by design — the public key is meant to be exposed — but it still creates risks.

Here’s how to lock things down:

Use Organization-Specific Keys with Domain Restrictions. For each client, generate a unique organization-level public API key tied to their specific allowed origins. If someone copies the key, they can’t use it from any other domain.

Or Set Up a Proxy Server. Route calls through your own server instead of directly to Vapi. The client’s website never sees a Vapi key at all — it communicates with your proxy, which holds the credentials and forwards requests.

Why This Matters More Than You Think

If you’re building voice agents with Vapi, you’re standing at a fork in the road. One path leads to being a talented technician who builds agents for clients — good work, good money, but capped by the hours in your day. The other path leads to being a Voice-as-a-Service platform — recurring revenue, scalable operations, and a business you can eventually sell.

The difference isn’t your agent-building skills. It’s the layer of experience you wrap around the agent. And that layer has to be white-labeled, secure, and self-service.

Here’s what changes when you deploy a proper client portal:

• Onboarding becomes zero-touch. Instead of scheduling a training call to walk clients through Vapi’s interface, you send them a URL. They log in, and everything they need is there.
• Billing stops being a monthly headache. Usage is tracked automatically, invoices are generated, and payments are processed through Stripe. You stop being a collections agent.
• Client retention goes up. When clients can see the value — appointments booked, leads qualified, time saved — they don’t question the invoice. The dashboard proves your ROI every day.
• You can charge more. A branded, self-service platform commands higher prices than “I’ll send you a weekly report.” You’re selling a product, not a project.
