The questions you should be asking

Unofficial tools, the ones that connect by reading a QR code, break WhatsApp's terms and are the main cause of bans in this market. ZeraSync runs on Meta's official API, the same path any approved provider uses, so that specific risk does not exist here.

What does still exist, on every official platform in the world, is the quality of the number: if you blast messages at people who never asked for them and they block or report you, Meta lowers your quality rating and can cap how much you send. That is a Meta rule and nobody can get around it. What we do is warn you when quality drops and explain what to change, instead of telling you to go read the Terms of Use.

Zera is a Meta-approved Tech Provider, with access to the WhatsApp Business management and messaging permissions. In practice, that gives us the technical ability to register and run your number on the official API.

We are not a BSP and not a Solution Partner, and we do not resell messages: message billing stays between you and Meta. We would rather explain that than display a badge we do not hold.

We charge nothing per message. You attach your payment method directly to your Meta account and pay Meta for what you use, at Meta's public rates. We are not a middleman in that billing and we put no toll on top of it.

For conversations the customer starts, and for those that come from an ad with a free entry point, the message cost to Meta is usually zero. Anyone charging per message with a margin baked in is making money on your volume, and that is how surprise invoices of thousands of reais (BRL) show up on other platforms.

You add your card in the dashboard right after signing up, but the first charge only happens on the day Meta clears your number to send messages. If you back out before that, or if Meta does not clear it, you pay nothing and we close the registration. Any amount that shows up on your statement on sign-up day is a validity check run by your bank, not a charge, and it drops off on its own within 48 hours.

No. The only amounts that exist are the ones on the public price list, per connected number, plus BotSync if you turn it on. There is no setup fee, no per-agent fee, no minimum volume and no overage charge. If we ever change prices, you get an email at least 30 days in advance and you can cancel before the new price takes effect.

As many as you want, at no extra cost. The price is per connected WhatsApp number, not per person. If your team grows from three people to ten, your invoice stays the same.

Usually between 2 and 5 business days. Meta's review of your business display name takes 24 to 48 hours, and your first message template, if you need one, goes through a similar review. That timeline belongs to Meta and we have no way to speed it up. Any vendor promising that you sign up and WhatsApp goes live on the spot is leaving this step out.

Yes, in most cases. The number starts running on the official API and stays yours. Some details depend on the state of the number today: whether it is a landline, whether it sits with another provider, whether it has already been used on another business account. That check is the first step of signing up. If your case is not viable, we tell you before any charge.

You pay nothing. The first charge only happens on the day the number is cleared, so a rejection simply closes the registration at no cost. When a rejection can be fixed, and most can, we tell you exactly what has to change: a display name that breaks the rules, a business portfolio without verification, or a website that does not meet the WhatsApp Commerce Policy. If it cannot be fixed, we cancel and give you your time back instead of pushing one more attempt.

You can, and the rule is simple: you do not cancel your current vendor until your number is working here. The worst horror story in this market is the customer who cancelled the old platform expecting activation in seven days and left the whole team idle, with no platform at all. We set up your account and run the migration in parallel, and switching off the old vendor is the last step, not the first.

Zera API delivers the official Meta Cloud API credential in your company's name, plus the webhook pointing to your server. It does not include a shared inbox: conversations are handled inside the system you already have. It is the plan for companies that have their own software or CRM and only need the official channel.

ZeraSync includes all of that plus the shared inbox for the team, with unlimited agents, queue by waiting time, labels, filters and history kept inside the company. It is the plan for teams that want several people answering WhatsApp on the same number.

No, and that is on purpose. BotSync is menus and rules. It answers in the first second, always with the same thing, and routes the conversation to the right queue based on the option the customer picks. It runs no model, has no variable AI cost, invents no prices and does not change its answer from one conversation to the next.

You set the options up in a form. It is not a drag-and-drop flow builder, and it is not going to become one. When the case calls for artificial intelligence running the business process, that is a project, and it is called Neural Core.

Yes, and it is where we came from. It is not part of the subscription because it is not software, it is operational work: someone has to design the campaign, write the ads, watch the results and adjust. It is a separate project, with scope and price agreed in a conversation.

The advantage of having both under one roof is that the ad, the conversation and the sale start being measured as one thing, and Meta learns from the people who bought, not from the people who only clicked.

Support is in Portuguese, over WhatsApp and email, during business hours, Monday to Friday, handled by the people who built the platform. It is not an outsourced call center and it is not a bot.

Being honest about our size: we do not sell 24-hour coverage, a contractual response time or a dedicated account manager, because Zera is a small team and promising that would be a lie. Promising support that does not exist is the most common complaint against the big platforms in this market, and we are not joining that line.

No retention call and no penalty. Cancellation takes effect at the end of the cycle you have already paid for, and there is no lock-in and no minimum term.

If you want to take your number to another provider, it is yours: the WhatsApp Business account and the business portfolio have been in your name since day one, and we hold nothing back to make leaving harder.

Your WhatsApp Business account and your business portfolio stay in your name, at Meta. Conversations sit in your own account on the platform, isolated from other customers' accounts. You can export them and you can ask for deletion. We do not sell, do not share and do not use your conversations to train any model.
