I want a custom WhatsApp-centric CRM that lets me work from one place instead of juggling multiple tools. At its core the system must handle automated responses, solid contact management and clear analytics/reporting, all powered through Meta API plus companion Web and App APIs so I can plug it into anything later without rewriting code. Beyond the usual CRM basics, I also need three business-critical add-ons built in: • Payment processing tied directly to chat threads • A lightweight ticketing flow for customer support • Marketing automation so I can trigger broadcasts or drip sequences from defined events Here is what success looks like to me: • Incoming WhatsApp messages are captured instantly and shown against the right contact record. • I can create rule-based auto-replies or chatbots through a simple UI. • Dashboards show message volumes, response times, conversion metrics and campaign performance at a glance. • Payment links or checkout widgets can be sent from inside the chat and reconciled back to each customer. • Support tickets open from a message, track status, and close when resolved. • Marketing workflows can be scheduled or triggered by tags, dates or transaction events. • The entire system exposes clean Meta, Web and App API endpoints so any future service can read or write data without friction. Keep the code modular and well-documented; I will need to hand it to in-house developers later. Let me know which tech stack you propose, estimated timeline, and any previous WhatsApp API projects you can point me to.

Hi there, I can see the real challenge here isn’t just a WhatsApp CRM , it’s building one clean system where messages, payments, tickets, and automation all stay perfectly in sync. I’ve built PHP/MySQL and API-driven business apps with modular architecture, and this fits well with a Laravel backend, Meta WhatsApp API integration, and a clean web UI for rules, contacts, reporting, and workflows. I’d approach this with a maintainable structure: WhatsApp event handling, contact/timeline storage, payment hooks, ticketing, and automation queues exposed through well-documented APIs for your in-house team. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. What payment provider should the chat-linked checkout use, and do you want the automation engine to support visual workflows or rule-based triggers only? Also, should the API be public with auth scopes or internal for your team first? Looking forward to your reply so we can finalize the exact plan. Thanks, Asad

You want one WhatsApp-centric CRM, end-to-end via Meta API plus companion Web/App APIs, so you can automate replies, manage contacts, and act on analytics without rewriting later. I’ll build a modular system that captures incoming messages instantly, maps them to the correct contact, and logs events for dashboards (message volume, response times, conversions, campaign performance). Add-ons built-in: (1) payment processing tied to chat threads with reconciliation back to each customer, (2) lightweight ticket flow launched from messages with status tracking/closure, and (3) marketing automation for broadcasts and drip sequences triggered by tags, dates, or transaction events. The admin UI will let you define rule-based auto-replies/chatbots and launch workflows. APIs will be clean and documented across Meta, Web, and App endpoints, enabling future services to read/write data safely. To start the right architecture, I will align on your required data model and workflow boundaries, then deliver iterative milestones for core CRM → messaging automation → payments/tickets → analytics and marketing.

WhatsApp CRMs fragment when each feature handles incoming messages in isolation instead of sharing a contact event stream. A webhook router feeding a unified contact graph, with modules subscribing to domain events independently, keeps every piece modular and hand-off-ready. The architecture: .NET 8 Web API receiving Meta webhooks, routing to a contact-centric domain model in PostgreSQL, Angular for the management UI, and a lightweight event bus decoupling payment reconciliation, ticketing, and marketing modules, each exposing its own REST endpoints for the Web and App API layer. The chatbot rule engine sits as middleware on the webhook router. Same pattern I used on the PMI hospitality SaaS, 70 tenants and 230+ hotels per tenant, where modules stayed isolated under async queue pressure. Every deliverable is covered: real-time message capture, chatbot builder UI, analytics dashboards, payment reconciliation per chat thread, ticketing flow, marketing workflows, and all three API layers. Happy to start with a small paid milestone, webhook ingestion plus contact model, so you can validate the foundation before committing to the full scope. Do you already have Meta Business API access approved, or does that need to be factored into the timeline?

Noticed you want a WhatsApp CRM with Meta API automation, contact management, payment processing in chat, ticketing, and broadcast campaigns — solid scope. We've built similar WhatsApp Business integrations using Node.js + React + MongoDB — webhook message capture, rule-based chatbot flows, multi-agent routing, and campaign scheduling. Adding payment links (Razorpay or your preferred gateway) inside chat threads is something we've done before. API-first architecture so you can extend or plug in other tools without rewrites. Each module (CRM core, payments, ticketing, marketing automation) can be scoped as a separate milestone for incremental review. Ping me to discuss your existing Meta Cloud API setup and preferred payment gateway.

Hi there, Your WhatsApp-centric CRM requirement will be resolved by building a modular system on top of Meta WhatsApp Cloud API where every message is captured in real time, linked to contacts, and used as the base for automation, payments, support, and marketing workflows. The system will include a rule-based automation engine for auto-replies and chatbot flows, a CRM layer for contact and conversation tracking, a ticketing module for support handling, and a marketing automation system triggered by tags, events, or transactions. Payment links will be generated inside chats and automatically mapped back to customer records.

I’ve worked on WhatsApp API automation and CRM-style systems where real-time messaging, workflows, and business actions are tightly connected in one platform. I can start immediately and will first define the architecture and data flow before development.
