FAQ
Q1: How does the milestone process work?
A: The project is delivered in 3 milestones — Requirements, First Draft, and Delivery. You'll review and approve each stage before payment is released for that milestone, so you always know what to expect and stay in control of the process.
Q2: What do you need from me before we start?
A: Your WhatsApp Business number (or help setting one up), basic property/project details, your brand name, and any preferred tone for the AI agent's persona. This is covered in the Requirements milestone.
Q3: Can I test the AI before final delivery?
A: Yes — the First Draft milestone includes a working version with the AI backend connected, so you can test real conversations and request changes before the final build.
Q4: Do I need a WhatsApp Business API account already set up?
A: No, I can help you set one up through Meta's Cloud API if you don't have it yet. This is coordinated during the Requirements milestone.
Q5: Can the AI understand Hindi/Hinglish messages?
A: Yes, the AI automatically detects the buyer's language and replies in the same style — Hindi, Hinglish, or English.
Q6: What happens if the AI can't answer a buyer's question?
A: Your sales team can click "Intervene" in the CRM dashboard to take over that chat manually anytime, and the AI will pause responding to that lead.
Q7: Do I need MongoDB, or is there a simpler option?
A: MongoDB is recommended for production use, but the system automatically falls back to local JSON file storage if MongoDB isn't configured — great for testing or smaller setups.
Q8: Is source code included?
A: Yes, full source code is transferred to you at the Delivery milestone, along with a walkthrough of the CRM dashboard.
Q9: Can I add more properties or features later?
A: Yes, additional property listings, integrations, or features can be added anytime as extra services after the initial delivery.
