I’m implementing a fully-automated sales closer that can greet every new lead, hold a natural back-and-forth conversation, qualify intent, answer common questions, book appointments and then push the entire interaction straight into our CRM for sales follow-up. The assistant must converse on the channels my customers actually use: WhatsApp, Email, Website chat, SMS, LinkedIn DMs, Instagram and Facebook Messenger. For prospects who prefer to talk, an AI voice agent should be able to pick up the phone, speak conversationally, and keep the call summary and recording logged back to the CRM as well. Key workflow requirements • Unified multichannel inbox and bot that responds instantly 24/7, hands off to a live rep when needed, and preserves the full chat or call history. • Lead qualification logic (e.g., budget, timeline, decision-maker) stored as structured data and synced to the CRM in real time. • Calendar integration so the bot or voice agent can offer open slots, book meetings and send reminders automatically. • Automated follow-up sequences based on stage or inactivity. • Visual dashboard that shows new leads, conversions, drop-off points and revenue attribution. Acceptance criteria 1. A working chatbot and voice agent live on all specified channels, answering at least 80 % of FAQs without human intervention. 2. Seamless sync with the chosen CRM (contacts, notes, deal stage, call recordings). 3. Appointment bookings reflected both in the CRM and Google/Outlook calendar. 4. Weekly performance report generated automatically and emailed to my team. 5. Clear handover documentation so future staff can adjust intents, flows and integration keys. Please architect, build, test and deploy the solution end-to-end, using the AI/automation stack you are most confident with (Dialogflow, GPT, Twilio, Make/Zapier, HubSpot API, etc.) as long as it meets the criteria above and is maintainable.

I can help with this, I will build your AI sales closer — multichannel chatbot, voice agent, CRM sync, calendar booking, and automated follow-ups — all deployed across WhatsApp, SMS, email, web chat, and social DMs. For the voice agent, I will use Twilio with a GPT-powered backend that streams responses in near real-time, keeping latency under two seconds so calls feel natural. Each call summary and recording will push directly into your CRM as a structured note tied to the contact and deal stage — no manual logging needed. Questions: 1) Which CRM are you currently using — HubSpot, GoHighLevel, or another platform? 2) Do you have existing FAQ content or sales scripts I should use to train the initial intent model? Ready to start whenever you are. Kamran

Your project is clear and ambitious. I’ve built similar AI-driven sales automation systems that integrate multichannel messaging and voice, syncing directly with CRMs like HubSpot and Salesforce. The main challenge is ensuring smooth handoff between AI and live reps without losing conversation context. I suggest using GPT for conversation flow combined with Twilio for voice and WhatsApp, plus Make for the automation and CRM sync—this stack handles real-time lead qualification and booking reliably. A quick question: do you have a preferred CRM in mind, or should I recommend one best suited for deep API integration and scheduling? Also, for voice calls, do you want full AI-driven conversations or limited to simple qualification and booking before handing off? Once we clarify those, I can design the unified inbox and visual dashboard to track all KPIs and automate weekly reports. I’ll deliver working bots on each channel that respond to 80%+ FAQs, sync all lead data, book calendars, and generate handover docs so your team can iterate easily. Ready to start architecting and building your AI sales closer system end to end.

Hey, I’ve reviewed your project and understand you need a fully automated AI sales closer that engages new leads across WhatsApp, email, website chat, SMS, LinkedIn, Instagram and Facebook Messenger along with voice calls. The goal is a unified system that responds instantly, qualifies prospects through natural conversation, handles objections and converts them into booked meetings across all channels. I will design a scalable automation setup using GPT based conversational agents with Twilio, WhatsApp Business API, Meta messaging APIs and an automation layer like Make or n8n.

Follow up sequences will trigger automatically based on inactivity or stage progression, while the voice agent handles calls and logs summaries and recordings into the CRM. You will get a fully deployed system including chatbot, voice agent, CRM integration, calendar booking and a reporting dashboard showing conversions, drop offs and lead quality. It will be tested to ensure strong FAQ coverage with smooth escalation to your team when needed.

Hey, this is exactly the kind of system I like building. I’d wire up a central AI layer (GPT-based) that handles conversations across channels, backed by a message orchestration layer so everything—chat, email, DMs, and voice—feeds into one unified flow. For messaging + voice, I’d integrate providers like Twilio, and connect socials (WhatsApp, IG, FB, LinkedIn) via their APIs or approved gateways. On the backend, I’d structure qualification as real data (not just chat logs), then sync it live into your CRM—whether that’s HubSpot, Zoho CRM, or a custom one—along with transcripts, call recordings, and stage updates. Calendar booking will plug directly into Google/Outlook with availability checks + auto reminders. You’ll get smart follow-ups triggered by behavior, plus a clean dashboard showing pipeline movement and attribution. I’ll also make sure human handoff is seamless so your team can jump in anytime without losing context. End result: runs 24/7, handles most conversations on its own, and keeps everything organized without manual work. I can move fast on this and keep it maintainable so your team can tweak flows later without breaking things.

I won’t build a basic chatbot—I’ll design a full AI sales system that actually qualifies, converts, and hands over clean data to your CRM. I’ll use a GPT-based conversational engine with structured output (for budget, timeline, intent), integrated across WhatsApp, email, web chat, SMS, and social channels via APIs. Voice agent will run through Twilio with real-time speech-to-text and natural responses. Calendar booking, follow-ups, and CRM sync (HubSpot/Zoho/etc.) will be automated with clear workflows. You’ll also get a dashboard tracking leads, conversions, and drop-offs.

Building a unified inbox that routes WhatsApp, Messenger, IG, LinkedIn, SMS, email, and web chat into one thread while keeping context is the tricky part here. I built an AI travel planner that handled multi-turn conversations with Claude and can wire up something similar for lead qualification, but this time routing across channels with a fallback to live handoff when the bot hits confidence thresholds. I'd use Twilio for SMS and voice, Meta Business API for Facebook/IG/WhatsApp, and webhook listeners for email and web chat, all feeding into a central state machine that logs to your CRM in real time. Voice agent can transcribe with Deepgram or similar, run the conversation through the same qualification logic, then dump call summary and recording as CRM notes. Calendar sync is straightforward once I see which CRM and calendar you're using. More examples at ffulb.com. If you can share API access or credentials for your CRM, WhatsApp Business, and preferred voice service I can assess the exact integration points and start wiring it up.

Hi there, I read your requirements for the AI Sales Closer Automation System. Building a unified system covering Voice, all requested text-based messaging platforms, Calendar, and CRM is a fantastic initiative. However, doing it from scratch or with disjointed tools will cause maintenance nightmares. As an AI Agent Developer, my approach is to use top-tier, trusted automation stacks and API integrations. This ensures the AI can seamlessly handle lead qualification, follow-ups, and answer 80% of FAQs automatically, while maintaining a unified inbox and visual dashboard. Proposed Terms: Budget: \650$ (Fixed Price) Timeline: 10 to 14 days Why this timeline and budget? A fixed milestone of \650$ ensures we have ample time (about two weeks) for rigorous testing across all integrated text channels, voice agents, and CRM syncing. Proper QA is crucial for a multi-channel system to ensure it actually closes sales rather than frustrating leads. I would love to discuss the specific CRM and calendar tools you prefer to use for this build. Looking forward to your response.
