# White-Label Voice AI: CallSphere Turnkey vs Vapi Build

> For agencies and resellers — what white-label voice AI launch actually requires. CallSphere bundles brand domain, RBAC, billing scoping. Vapi gives you primitives.

## TL;DR

White-label voice AI is what marketing agencies, MSPs, telecom resellers, and vertical SaaS companies actually want — to ship voice AI under their own brand with their own pricing. Doing this on Vapi means **building the platform around the platform**: dashboards, RBAC, multi-tenancy, billing scoping, brand theming. CallSphere ships a **white-label-ready platform** with brand domain, brand colors, scoped tenants, and reseller billing built in.

## The Hook: White-Label Is a Platform, Not a Theme

Most "white-label" pitches stop at slapping your logo on someone else's UI. Real white-label requires:

- **Brand domain** — the dashboard lives at agent.youragency.com
- **Brand theme** — your colors, your logo, your typography in every screen
- **Scoped tenancy** — each of your end-customers is a separate tenant; one customer cannot see another
- **Reseller billing** — you bill your customers, you owe the platform
- **Reseller analytics** — you see all your customers in a roll-up dashboard, but each customer only sees themselves
- **Reseller-grade RBAC** — admin / customer admin / customer manager / customer agent levels
- **Reseller support model** — your customers contact you; you contact CallSphere

Vapi customers rebuild every one of those. CallSphere ships them.

## Vapi Reality: Build Around the Platform

A typical Vapi-based white-label engagement takes 4–6 months and 1,000+ engineering hours. You build:

| Component | Approx hours |
| --- | --- |
| Brand domain + theme system | 80 |
| Multi-tenant data model | 60 |
| Reseller-grade RBAC | 80 |
| Customer dashboard build | 160 |
| Billing scoping (per-tenant invoicing) | 80 |
| Support workflow (your team triages) | 40 |
| Onboarding flow per new customer | 60 |
| Compliance for end-customer industries | 100+ |

Total: **~660 hours minimum**, on top of the 800 hours of base voice AI work. That is why most agencies abandon white-label after the first scoping doc.

## CallSphere Reality: White-Label As First-Class

CallSphere's multi-tenant model is the foundation. White-label is configuration, not engineering.

What you get on Growth tier or above (Enterprise for full reseller billing).

### Brand domain

Set up agent.youragency.com pointing at CallSphere. CallSphere serves the dashboards under that domain. Your customers think they are using your product because they are.

### Brand theme

Logo upload, color palette, typography presets, custom CSS overrides for power users. Every dashboard screen renders with your brand. PDF exports (e.g. compliance reports) carry your branding too.

### Scoped tenancy

Each of your end-customers is a top-level tenant (practice / company / org). Tenants cannot see each other. You can create unlimited tenants on Enterprise; tier-limited on Growth and Scale.

### Reseller billing

Set your customer's price; CallSphere bills you the platform fee. You pocket the margin. Invoicing automation per customer. Stripe Connect integration on the roadmap (Q3 2026); manual invoicing supported today.

### Reseller analytics

Roll-up dashboard sums calls, minutes, lead score distribution, escalations across all your customers. Drill in to a specific customer to see only their data. Per-vertical KPI tiles.

### Reseller-grade RBAC

Four role tiers — agency admin, agency manager, customer admin, customer manager / supervisor / viewer. Agency-level users can act on behalf of customers (with audit log) for support; customer-level users only see themselves.

### Onboarding flow

A reusable onboarding wizard you can run for each new customer in under 30 minutes. Pick vertical, configure data, bind number, invite users. Same wizard for every customer.

## Realistic Example: Healthcare Marketing Agency

A digital marketing agency that serves 60+ behavioral health practices wanted to add an "AI receptionist" line item to their retainer. Three options were on the table.

**Build on Vapi:** scoping doc estimated 4 months and ~$140k in engineering. Killed.

**Resell a competitor's white-label SaaS:** locked into their roadmap, no control over the verticals, lost margin to a long markup chain.

**CallSphere white-label (Growth tier):** brand domain set up day 1, first customer onboarded day 4. By month 2 they had 8 paying customers. Margin: $400/customer/month. Pure incremental ARR for their agency.

## How Reseller Billing Works in Practice

CallSphere bills you (the reseller) the platform fee monthly per tenant. You bill your end-customers whatever you want. The simplest pricing models we see:

- **Flat per-customer markup** — CallSphere costs you $X, you bill $X + $Y per customer
- **Tiered to verticals** — different markup for healthcare vs salon to match value capture
- **Bundled in retainer** — agency rolls voice AI into the retainer at a fixed line-item price
- **Usage uplift** — flat base + per-minute markup for outbound campaign customers

CallSphere does not enforce any specific model. We are the wholesale plumbing.

## FAQ

### Can I limit which verticals my customers see?

Yes. The reseller admin can enable/disable verticals per customer. A behavioral health agency might only enable Healthcare and After-Hours; a real estate marketing firm only Real Estate.

### Do my customers know they are using CallSphere?

Only if you want them to. Default is fully white-labeled (your domain, your logo, your support workflow). The HIPAA BAA chain still requires CallSphere as a sub-processor; you disclose that in your DPA.

### What about the support workflow?

Two-tier. Your customers contact your team. Your team triages and either resolves or escalates to CallSphere via a dedicated reseller queue. Most agencies learn enough in 60 days to resolve ~80% of tickets directly.

### Is there a minimum customer commit for Enterprise?

Yes. Enterprise white-label tier starts at a specified annual minimum; talk to sales for current numbers. Growth tier has no minimum but per-tenant fees apply.

### Can I migrate existing customers from another voice AI vendor?

Yes. The 7-day playbook works per customer. Most agencies migrate one or two customers as proof, then ramp.

### How does compliance work?

CallSphere holds the parent BAA / SOC2 / DPA chain. You sign reseller terms that pass the relevant clauses through to your end-customers. Healthcare resellers also sign a BAA with us.
