Frequently asked questions
Are Voice AI and WhatsApp AI the same agent?
No. They are two different agents: one handles calls and the other chats over WhatsApp. They are built and managed on the same platform and share the same balance.
Do I need to sign up for both?
No. You turn on the channel you need, when you need it, without adding another vendor.
Who builds the agents?
You do: Go4Clients lets you build them with a wizard or from templates. And if you prefer, you can ask our experts to build them for you.
What happens when the AI can't resolve something?
On voice, you decide what the agent does: it can say it doesn't have that information or transfer the call to someone on your team. On WhatsApp, the conversation goes to a human agent in the chat desk.
How does the balance work?
You top up every month and use it on calls or on AI messages. Validity is 30 days and unused balance expires at the end of the cycle. You can top up manually or schedule automatic top-ups, and there is no lock-in. If your balance runs short, you can also make an additional manual top-up whenever you need.
How is each channel billed?
Voice is billed per minute (the first 20 seconds of each answered call, then per second). If a voicemail is detected, only the detection ($0.0075) is charged and that call does not use minutes. WhatsApp is billed per AI message: each reply the AI sends counts as one message, no matter how long it is.
What doesn't Go4Clients charge for on WhatsApp?
Nothing from Meta, nor the messages sent by the end customer, nor those sent by a human agent from the chat desk. WhatsApp numbers are not included in the offer.
Can I try it before committing?
Yes. If you sign up for any plan, the proof of concept is included: you use your plan's minutes and we build your first agent. If you'd rather test before choosing a plan, you can buy the proof of concept for $100 USD (one-time payment), which includes 400 minutes and the build of your first agent.
How do I link my business to WhatsApp?
Your business is linked through its Meta business account (WhatsApp Business). Your business must be available in that account, or you need a WhatsApp number to link it.
What does the customer pay Meta directly?
Meta charges for each template and, starting October 1, 2026, for each reply within 24 hours, at the recipient's country rate. You need an active payment method in your Meta account (Billing Hub).
Do you help with Meta?
Yes. We guide you through Meta onboarding: verification, WABA account and number.
