I want to roll out a configurable, AI-driven WhatsApp solution that lets a small-to-medium business handle sales, marketing, and frontline support from a single number. The core focus is sales enablement—capturing and nurturing leads, booking appointments automatically, and pushing every interaction into our CRM—yet the same bot must still answer routine FAQs and process simple orders so human agents can focus on high-value conversations. Here is what I need from you: • A WhatsApp Business API–based bot powered by an LLM (ChatGPT or similar) that understands natural language in English and Spanish. • No-code style dashboard where I can edit the knowledge base, tweak conversation flows, and switch on/off modules such as lead generation, appointment booking, and order processing. • Native CRM integration (HubSpot at launch, with webhooks for others) so all leads, tags, and transcript data sync in real time. • Calendar connector for automatic appointment scheduling, with reminders sent over WhatsApp. • Secure order-capture flow (simple catalogue, cart, checkout link) that the AI can guide customers through. • Human-handoff logic: escalation to a live agent inside WhatsApp or via email when the bot’s confidence drops. • Deployment, brief documentation, and a short video walk-through so my team can manage the platform without developer intervention. Acceptance criteria 1. Bot can recognise and respond correctly to at least 90 % of a supplied FAQ list. 2. New lead records appear in HubSpot within 10 seconds of capture. 3. Appointment slots sync bidirectionally with Google Calendar. 4. All components run on my cloud account and pass a brief security review.

Hi, I understand you need a configurable bilingual WhatsApp Business API bot that supports sales enablement, FAQ automation, lead capture, HubSpot sync, Google Calendar booking, simple order capture, reminders, and human handoff from one business number. I have experience building WhatsApp API solutions, LLM-powered assistants, HubSpot integrations, webhook-based CRM sync, Google Calendar connectors, no-code style admin dashboards, order flows, multilingual knowledge bases, and secure cloud deployments. I can build a modular platform with editable flows and knowledge base, confidence-based escalation, real-time lead/transcript syncing, appointment automation, checkout-link order guidance, documentation, and a short walkthrough for your team. Q1: Are you using Meta WhatsApp Cloud API directly or a provider like Twilio or 360dialog? Q2: Should the dashboard be custom-built or based on an existing no-code/admin framework? Q3: Which cloud account should the solution run on: AWS, Google Cloud, Azure, or another provider? Best regards, Stratos

I see you're looking to build an AI-driven WhatsApp sales-support platform for small-to-medium businesses. That's a smart move to enhance customer support and lead generation. I have around 10 years of experience with AI chatbots and natural language processing, which should fit well with your vision. Your goal seems to be creating a configurable solution that can adapt to different business needs. That’s essential for helping clients engage effectively with their customers. Some similar things I've built include a regional booking platform for a tutoring company, an internal CRM for a property agency, and a React Native field-reporting app. Let’s bring your idea to life! Could you please clarify the following questions to help me better understand the project? Q1: What specific features or capabilities do you envision for the configurable AI solution? Q2: How do you plan to integrate this platform with existing sales or customer support systems? Q3: Are there any particular challenges or constraints you've identified that we should address early on?

Meta's WhatsApp Business API verification takes 3-10 business days for new accounts and it can't run in parallel with the build, so I'd want to know if your number is already approved before locking in 14 days. On the integrations: HubSpot and Google Calendar are both bidirectional, which means you need a source-of-truth rule per field. A contact updated from WhatsApp while HubSpot has a conflicting value will silently corrupt data if that isn't handled upfront. I'd wire sync logs so your team can see what changed and when. For the NLU layer, language detection works better at the message level than the conversation level, since users switch between English and Spanish mid-thread more than you'd expect. Routing intents before routing language tends to work well here. The no-code dashboard scope is worth a quick clarification too. Letting your team manage conversation flows via UI is a different build from letting them configure LLM prompts and handoff escalation rules via UI. Both are doable, they're just scoped differently. One milestone at $700, deployed to your own cloud, 14 days. This is an indicative estimate from the brief; I'll give you a firm quote once the scope is locked.

I understand you're looking for a robust AI WhatsApp platform that seamlessly integrates sales enablement with frontline support, similar to how platforms like Intercom or Drift automate customer journeys. My experience building custom chatbot solutions for lead qualification and automated appointment booking directly addresses your need for a single, intelligent interface for your SMB. My approach will involve leveraging the Twilio WhatsApp Business API for reliable messaging, integrated with a powerful LLM (like GPT-4 via OpenAI API) for natural language understanding and response generation. I'll design a state machine architecture to manage conversation flows, differentiating between sales, support, and order processing intents. This will include API integrations for CRM (e.g., HubSpot, Salesforce) to push leads and appointments, and potentially e-commerce platforms for simple order fulfillment. How do you envision the handover process from bot-qualified leads to human sales agents? Are there specific CRM fields you prioritize for automated data capture? I'm confident I can deliver a solution that meets your requirements and would be happy to discuss your project in more detail.

Hi, I hope you’re doing well. I reviewed your project details, and based on my recent experience, I believe I can help you a lot. I’ve worked with both the official and unofficial WhatsApp APIs, and I’m currently maintaining a system that has been using these APIs for over three years. Because of that, I think I can bring valuable experience to your project. I do have one question: are you planning to use the official WhatsApp API or an unofficial one? Are you familiar with the pros and cons of each approach? If you’d like to discuss it further, feel free to send me a message in the chat. I’d be happy to share my experience and help you choose the best option.

Hello! Keeping lead data in sync between WhatsApp, HubSpot, and a human agent without losing anything in the middle is the hardest part of this build and I have solved it before.

Hello, "WhatsApp Business API–based bot" needs a configurable AI‑driven solution that captures leads, books appointments and handles orders from a single number. I'll run the LLM in an async worker queue and cache the top‑10 FAQ intents so the bot replies under 2 seconds even on cold start, and I'll set up a HubSpot deduplication step to prevent duplicate lead records when the same phone number appears in multiple campaigns. The no‑code dashboard will be built with React and a JSON schema editor, letting you toggle modules without touching code. Do you already have a HubSpot API key and a Google service account ready for the integration? Looking forward to working with you. Artur Giżycki

Hi, I can build this as a WhatsApp Business API solution that feels useful for sales first, while still covering FAQs, bookings, simple orders, and clean handoff when a human should step in. I’d structure the bot around English/Spanish conversations, a managed knowledge base, HubSpot lead sync, Google Calendar booking, WhatsApp reminders, and a controlled order flow with catalogue/cart/checkout links. The LLM would be guided by business rules so it does not invent answers, and low-confidence or sensitive conversations would be escalated with the transcript and customer context attached. For the dashboard, I’d keep it no-code style: edit FAQs, update prompts/knowledge, toggle modules, adjust flows, and review activity without touching the backend. Everything would run in your cloud account, with webhooks ready for future CRMs. Question 1: Do you already have an approved WhatsApp Business API number, or should setup be included? Question 2: Should live handoff go to a shared inbox, HubSpot conversation, or a specific staff member by department? Regards, Houssame

Hello, there! I am highly confident in this project because my expertise in WhatsApp Business API, LLM integration, and CRM sync mirrors your exact requirements for a scalable sales enablement bot. I will start by setting up the WhatsApp API via Twilio or 360dialog, connecting it to a custom LLM middleware that handles dual-language NLP. This engine will be linked to a central knowledge base and HubSpot for real-time lead ingestion and tag management. I will implement a custom dashboard to give you full control over the conversation flows and modules without touching any code. Next, I will integrate the Google Calendar API for automated booking and reminders, alongside a secure checkout workflow for order processing. I will develop the human-handoff logic with confidence-score thresholds to ensure a seamless transition to your agents when needed. Finally, I will provide the full documentation and video tutorials to ensure your team has total operational independence. I would love to chat further to discuss the specific technical details and your preferred cloud environment. Best Regards, Mauro.
