Bottom Line

Pick based on who's building it

If your agency has developers and wants full control over every line of the voice pipeline, Retell is a legitimate choice. If you want a resellable, white-label voice platform — inbound and outbound — your team can configure and brand this week without hiring engineers, that's what NovaReps is built for.

The calculator above is the concrete version of this trade-off: on a per-minute API, your platform cost rises every time a client's agent gets used more — the moment a client succeeds is the moment your margin tightens. On a flat fee with BYOK, your provider costs still scale with usage, but at cost, direct from OpenAI/Anthropic and Twilio — nothing is layered on top as your clients grow.

NovaReps vs Retell AI — Common Questions

Is Retell AI a bad product?
No — Retell is a strong developer platform if you have engineers and want full control over the voice pipeline. The comparison isn't about quality, it's about what you're buying: an API and toolkit, versus a finished product an agency can white-label and resell without an engineering team.
Can I white-label on Retell?
Retell's public positioning is a developer API, so white-label client account management, branded domains, and reseller billing are not marketed as built-in features — an agency wanting those would build them as a layer on top. NovaReps ships that layer natively.
Does NovaReps also support BYOK like Retell?
Yes. Bring your own OpenAI/Anthropic, Deepgram/ElevenLabs, and Twilio accounts — the same BYOK model, plus the white-label reseller layer and outbound campaign tooling on top.
Does NovaReps do outbound the way Retell's API can be used for outbound?
Yes — outbound dialer campaigns are a native, configurable product on NovaReps (not just an API primitive), with a built-in safety stack: calling-hour windows, daily caps, DNC list, cooldowns, and a kill switch.
How long does it take an agency to launch its first client on NovaReps vs. Retell?
Typically same-day on NovaReps once your branding and provider keys are connected — client account management, billing, and the reseller layer are already built. On Retell, that layer is something your team builds first; the API itself is fast to call, but the agency-facing product around it isn't included.
Does NovaReps offer per-tenant telephony isolation the way I'd build with Retell + my own Twilio?
Yes, natively — every client's calls and numbers run on isolated Twilio/Telnyx subaccounts by default, without your team having to design that isolation architecture yourselves.

Skip the build.
Resell a finished platform.

White-label, BYOK, your own Twilio, inbound + outbound — live in a day, not a dev sprint.
