FAQ

What is the best white-label AI voice agent platform in 2026?

For most agencies, Famulor. You get your domain, logo and colors, a workspace per client, your own prices and billing through Stripe Connect, with EU hosting in Frankfurt. Trillet suits agencies that want a $99 entry plan, Convocore agencies that need an EU region, and VoiceAIWrapper agencies already on Vapi or Retell. Famulor is our own product, so check the sources.

How do agencies make money reselling AI voice agents?

A common model is a monthly retainer per client plus a markup on minutes. Platforms support this with client workspaces and Stripe billing: Famulor through Stripe Connect, Trillet with custom minute markup on its Agency plan, and VoiceAIWrapper through your own Stripe account. Check who owns the billing relationship and whether your clients ever see the vendor.

What does a white-label AI voice platform cost?

Entry plans start at $79 to $99 a month: VoiceAIWrapper Growth at $79, Trillet Studio at $99 and Stammer AI Pro at $99. Unlimited client workspaces cost more, such as Trillet Agency at $299. Famulor’s Agency plan starts at €216/mo billed yearly, plus the €499/mo white label add-on. Compare the full cost per minute too.

Can clients see which platform powers my service?

Not on a full white-label setup. Famulor, Trillet, VoiceAIWrapper, Convocore and Stammer AI let you use your own domain and branding. Check the details plan by plan: custom domain, branded emails, client logins and invoices. On entry plans such as Trillet Studio the custom domain is not included, and Stammer AI’s Standard plan has no white label.

Which white-label voice AI platforms offer EU hosting?

Famulor is hosted in Frankfurt. Convocore offers EU-region infrastructure in Frankfurt, and Synthflow runs an EU cluster for its enterprise workspaces. Trillet lists residency across EMEA on Enterprise and Australian residency for clients who need it. We found no stated data location for VoiceAIWrapper, Stammer AI, Assistable.ai or HighLevel.

What changed at Synthflow for agencies in 2026?

Synthflow’s docs say in-product reselling through Stripe was removed on September 15, 2026. Subaccounts, custom domains and branding are still documented, but client billing now has to run outside the app. Its pricing page lists enterprise contracts from $30,000 a year. Agencies that rebilled clients inside Synthflow can compare Stripe-based options such as Famulor or Trillet.
