Frequently asked questions

Can the chatbot use our existing WhatsApp number?
Yes. The number is connected to the WhatsApp Business Platform (the API). Depending on your country and provider, it either moves fully to the API, with your team replying from a shared inbox, or keeps the WhatsApp Business app on the same number alongside the API. We confirm which applies during setup.
How does Meta charge for WhatsApp messages?
Per delivered message. Template messages (marketing, utility and authentication) are billed by category and country. Since 1 October 2026, service replies inside the 24-hour window are also billed after the first 1,000 per phone number each month. We estimate your monthly fees from your real chat volumes before you commit.
Does Meta allow AI chatbots on WhatsApp?
Yes, for bots that serve your own customers, such as support, sales, bookings and order updates, as long as you follow the opt-in, template and quality rules. Meta does not allow general-purpose AI assistants as the main product on the Business Platform.
Can it reply in Urdu and Roman Urdu?
Yes, including messages that mix Urdu, Roman Urdu and English, and voice notes, which are transcribed before the bot answers. We test it on real local conversations before launch.
How long does it take, and who owns it?
A focused chatbot for one use case typically takes 2–4 weeks; links to a CRM, ERP or payments add time. You own the code and the data: it runs in your accounts, not on a monthly per-seat platform.
