What happens when a white-label AI demo hits its cap?
When your demo hits its usage cap, the live voice and chat nodes pause and the rest of the page keeps working. Here is what a prospect sees, how other voice platforms handle overages, and when a hard pause is the wrong tradeoff.

When your white-label AI demo hits its usage cap, the live voice and chat parts pause until the next billing cycle, and everything else keeps working. The prospect sees a neutral message that the demo is not accepting calls right now. They never see a billing notice or your plan name, and you never get a surprise invoice. That is how it works on Lumina Sales, and it is a design choice worth understanding before you send a demo link to forty prospects.
This post covers what the cap is, what a prospect actually experiences, how other voice platforms handle the same moment, and the cases where a hard pause is the wrong tradeoff for you.
What counts as the cap on a Lumina Sales demo?
The plan is $49 a month, and the limits are listed next to the price: 100 live voice minutes, 500 chat messages, and 50 website audits per month, plus three published demos at once and a five-minute limit on any single call. Draft demos are unlimited.
Those voice minutes work out to about forty demo calls if the average call runs two and a half minutes. If every prospect talks for the full five minutes, you get twenty. We walked through that planning math in Will 100 voice minutes cover your demo pipeline?, so I will not repeat it here.
The cap is per month and per meter. Running out of voice minutes does not touch your chat messages, and running out of audits does not touch your voice minutes. Each one pauses on its own.
What does a prospect see when the cap hits?
Only the live nodes stop. The rest of your demo page still loads, still carries your logo and colors, and still shows your booking link. The portal and your dashboard keep working too.
On the live node, the prospect gets a short, neutral message that the demo is not accepting calls right now. It does not say "upgrade," it does not mention Lumina Sales, and it does not name your plan. From their side it reads like a business that is temporarily not picking up, which is a thing that happens to real businesses.
You can test this yourself. Open one of your own demos in a private window once you are near the cap and look at what a stranger would see. It takes thirty seconds and it is the only way to know your page degrades the way you want.
Why pause instead of bill overages?
The usual alternative is metered billing, where you keep going and pay for what you use. Plenty of voice platforms work that way, and the numbers can drift further than people expect.
Retell publishes a range of $0.07 to $0.31 per minute for pay-as-you-go voice agents, and includes 20 concurrent calls free per account. Its own guide on usage-based pricing lists the ways bills creep. because speech recognition keeps listening, test calls bill at production rates, and burst calls above your concurrency limit add a $0.10 per minute surcharge. A monthly budget, where available, emails you at 80% and 100% and pauses calls at 100%.
Deepgram's pricing page describes a similar shape for its Voice Agent API. Usage past prepaid credits on the Growth plan bills at the Growth rate plus 10%, and requests beyond a concurrency limit are "queued or rejected". Without a card on file, requests return a 402 once credits run out.
None of that is unreasonable for a production phone line. A client's receptionist should keep answering on the 31st even if the month was busy. But a demo is different. A demo is marketing spend, and nobody wants a marketing line item that can run away because one prospect forwarded the link to their whole team and everyone called at once.
So the plan pauses. You know the maximum cost of the demo side of your business before the month starts. It is $49.
Is the voice usage in a client build capped the same way?
No, and this trips people up. The 100 minutes belong to your demo, which is the thing you send before the close. Voice builds you order for paying clients are separate, and they are billed per minute at the wholesale rate agreed on your 30-minute pricing call. On the top tier that is $0.35 a minute on voice, on top of the setup fee and monthly.
That is a variable cost on a real client line, which is why we wrote how to charge clients for AI voice minutes. Bundle an allowance, set an overage rate above your cost, and check real usage at 60 days. Do not treat the demo cap and the client meter as the same thing.
When is a hard pause the wrong tradeoff?
I would rather you hear the downsides from us than find them in the middle of a campaign.
The first is timing. A pause is invisible to you unless you check. If you send a demo link to a hundred prospects on the 24th and the minutes ran out on the 22nd, those prospects click a link that politely refuses to talk. You paid the cost of the outreach and got the neutral message. Check the usage page in your dashboard before any large send, and do the math on the days left in the cycle.
The second is that the pricing page lists no pay-as-you-go top-up for demo minutes. If you run a high-volume outbound motion with many people on the same demo, one workspace may be too small for it. Spread prospects across your three published demos, but remember that all three share the same monthly pool.
The third is the five-minute limit on a single call. A curious prospect who wants to keep testing will hit it. That is on purpose, because it protects the pool, but it means the demo is a taste and not a trial. If your sale needs a ten-minute live conversation, book a call and run it yourself.
If you sell to very large teams where fifteen people will each want to try the voice agent on the same afternoon, a plan sized for a solo agency will pinch. This product is built for agencies of one to ten people sending demos to local service businesses. It is not built to be a call center load test.
How do you avoid running out mid-month?
A few habits keep the pause from ever reaching a prospect.
Send in waves. Instead of one blast, send ten to fifteen demos at a time and watch how many minutes they burn. Most prospects open the page, try the chat, and leave. A smaller share calls. Your own ratio will tell you more than our averages.
Use the audit and chat nodes first. They draw on separate meters with higher caps, so a prospect can see a website audit or chat with the agent without touching your voice minutes. Lead with those in the message and let the voice call be the second step.
Keep your own testing short. Every call you make while building a demo uses the same pool. Test with chat when you can, and save the voice minutes for the final check.
Watch the dashboard, since it also shows when a prospect opened your demo and how long they talked. That is useful sales information, and it doubles as a usage meter. See the platform overview for what the activity view shows.
FAQ
Does a paused demo hurt my brand?
Not much, if the message stays neutral. The prospect sees your branding on a page that says the demo is not accepting calls right now. That reads as a busy business, not a broken product. The sandbox disclosure stays visible either way, as covered in our post on demo sandbox disclosure.
Will I get a bill if I go over?
No. The plan never sends a metered invoice. When a limit is reached, the live node pauses until the next cycle. Client voice builds are the only per-minute billing, and those are agreed in advance on a pricing call.
What resets at the start of the next cycle?
The voice, chat, and audit meters all reset, and any paused nodes start taking calls again. Your page, portal, and drafts never stopped working. If you cancel, published demos unpublish and everything stays as a draft until you resubscribe.
Can a prospect see how many minutes I have left?
No. The prospect sees only the demo page and, at the cap, the neutral not-accepting-calls message. Usage numbers live in your dashboard.
Should I tell prospects the demo has limits?
If it comes up, yes, and say it plainly. The demo is a sandbox with a five-minute call limit, and the real system for their business has its own allowance agreed up front. Prospects trust the answer more when you volunteer the limit than when they find it.
Next step
Open your usage page today and write down three numbers: minutes used, days left in the cycle, and demos you plan to send. If the first number looks too high for the third, hold the next batch until the meters reset. If you do not have a workspace yet, you can start one at $49 a month, try the live demo on the homepage first, and read the full FAQ for the other limits.
