A white-label AI receptionist is an AI that answers your clients’ business phones 24/7 and books their appointments, sold under your agency’s brand at a price you set. You can build it on a voice-AI platform and wire everything else yourself, or resell a CRM that already has the receptionist inside it. The wholesale math between those two routes is what decides your margin. Here are both, with current prices (checked October 2026) and the numbers for three to ten clients.
Route 1: white-label a voice-only platform
Voice-AI platforms sell agencies a builder: you assemble the receptionist, wire up telephony, and resell the result.
- Synthflow has a white-label and reseller program, but its pricing page now lists only Enterprise contracts “from $30,000 annually,” scoped by sales. A third-party breakdown (October 2026, by a competitor) reports the white-label add-on at $2,000/mo and says the old self-serve agency plans are no longer offered to new users. Synthflow’s own billing docs add that in-product reselling ended on 15 September 2026, so it no longer bills your clients’ sub-accounts. Get a quote, and see our Synthflow alternatives.
- Developer platforms like Retell price by the minute ($0.07–$0.31/min depending on configuration, per Retell’s pricing page, October 2026), and you build everything around the call yourself.
You get control, and you also inherit the rest of the product: the client still needs somewhere for the booking to land, the contact to live, the follow-up to fire, and the invoice to go out. Every one of those is an integration project you own, per client, forever. Voice-only reselling suits agencies that are genuinely technical and want to sell voice as the whole offer.
Route 2: white-label the platform the receptionist lives in
The other route is reselling an AI receptionist that comes with the CRM around it. Stack Space is built as the AI receptionist that’s also your CRM: the receptionist answers and books, the call lands as a contact with a transcript, follow-up automations fire, and Stax, the AI brain, manages the 17-employee AI workforce behind it — all inside a sub-account wearing your brand. Stax trains the receptionist; it never answers the phone itself.
White-label reselling starts on the Professional plan ($355/mo): your logo on a branded subdomain of ours, retail plans you define, billing on your own Stripe. The Agency plan ($800/mo) scales it for a full client book. Wholesale has no per-sub-account base fee — just each client’s usage at posted rates: voice $0.30/min, texts $0.03/segment, AI actions $0.02, lead lookups a flat $0.13 each (any lead type), email free.
Hear the receptionist take a real call — it rings your phone in about a minute.
The margin math, with the edges shown
Pick your own retail price; this example uses $297/mo. Say you’re on the Professional plan and each client’s receptionist answers about 100 minutes a month (roughly 25–50 calls):
| Your book | Client billing (your Stripe) | Wholesale ($355 flat) | Usage (~100 min × $0.30) | AI phone numbers ($5 each) | Spread (before Stripe fees) |
|---|---|---|---|---|---|
| 3 clients | $891 | $355 | $90 | $15 | $431 |
| 5 clients | $1,485 | $355 | $150 | $25 | $955 |
| 10 clients | $2,970 | $355 | $300 | $50 | $2,265 |
Three footnotes that keep the table honest:
- This is arithmetic, not a promise. You still have to sign and keep the clients. Any vendor guaranteeing reseller income is selling income the software can’t deliver.
- Usage is real; budget it. The voice line above assumes moderate volume. Heavier clients cost more and should be priced higher, and the per-unit rates are posted so you can quote before you sell.
- The platform fee spreads; usage doesn’t. At 10 clients the $355 fee is $35.50 per client, and that share keeps falling as you add clients. Usage doesn’t: each client adds its own minutes (about $30 a month in this example) and its own AI phone number ($5/mo, since client sub-accounts don’t include one), so your all-in cost here is about $70.50 per client at 10 clients, and about $153 per client at 3. For comparison, GoHighLevel charges its AI Employee add-on at $50–$97/mo per sub-account on top of its plan (GoHighLevel pricing, October 2026). That structure is why we wrote a whole teardown at white-label CRM.
Break-even at $297 retail is two clients on Professional. The wider packaging playbook (what to bundle, what to charge) is in how to resell marketing services.
What are you actually selling?
The clients don’t want an AI receptionist. They want the 7am caller booked before a competitor answers, the after-hours emergency routed to a human, and proof it happened. Sell that:
- Coverage: answered 24/7, including the after-hours and weekend calls a small office can’t staff.
- Proof: every call transcribed, with a summary texted to the owner after each one.
- The loop closed: booked slot, follow-up sequence, review request, with appointment reminders and invoices going out by text from our registered number (or from a $15/mo managed number of the client’s own as soon as it’s added; a number the client brings waits on its carrier registration). A voice-only bot stops at the message; the platform version finishes the job.
Demo it the direct way: the receptionist answers live in the browser (the demo is on the AI receptionist page), so a prospect can try to stump it on your first call together. Nothing you say in a pitch converts like the owner hearing their own trade’s questions answered, and nothing builds trust like the recap landing in the CRM while you’re still in the meeting. Sell the demo, then let the first week of transcripts sell the renewal.
The lock-ins to dodge
Whatever route you pick, walk if you see:
- Per-location or per-seat AI fees. The feature your clients most want is the one you can least afford to rent by the unit.
- Rev-share instead of flat wholesale. If the vendor takes a percentage of your retail forever, your pricing is effectively theirs.
- Vendor-owned billing. If client payments run through the vendor, you don’t own the customer relationship.
- No exit. Month-to-month terms and exportable data, checked before onboarding, not after.

FAQ
What is a white-label AI receptionist? An AI phone answering service you resell under your own brand: your logo and brand on the platform, your retail price, billing on your Stripe, with the vendor running the AI invisibly. Clients get 24/7 answering and booking; you keep the spread between retail and wholesale.
How much does it cost to white-label an AI receptionist? Voice-only platforms run from per-minute developer pricing ($0.07–$0.31/min on Retell, October 2026) up to quoted programs: Synthflow now lists Enterprise contracts from $30,000 a year, and a third-party breakdown reports its white-label add-on at $2,000/mo. Add everything you build around them. Stack Space starts white-label reselling at $355/mo (Professional) with no per-sub-account base fee — client usage bills at posted wholesale rates, including 30¢ a voice minute. That per-minute rate is above the developer platforms’, and it comes with the CRM, booking, and follow-up already inside, so compare the delivered package rather than the meter.
What should I charge clients for an AI receptionist? There’s no standard price. Price against the client’s alternative: a human answering service, which still mostly takes messages (we broke down what answering services really cost). Bundle the receptionist with follow-up and reviews and you can justify charging more.
Do I need technical skills to resell an AI receptionist? On the platform route, no: create the sub-account, describe the client’s business in a paragraph, point the phone line, and test-call it together. On the voice-only route, yes — telephony, integrations, and guardrails are your build.
Can I try it before reselling? There’s no free trial — plans start at $30/mo (Launch), which is the honest way to test: put the receptionist on a real line, read a week of transcripts, then decide if it’s sellable. No contracts — cancel anytime.
Start with one client. Spin up one branded sub-account, forward a missed-call line to it, and show a prospect their own business being answered.
