Full Description
Your customers are already on WhatsApp. The question is whether your business is keeping up with them — or leaving them waiting.
This service delivers a bespoke, GPT-4 powered WhatsApp chatbot built specifically around your business workflows. Whether you need to automate customer support, handle appointment scheduling, process orders, collect feedback, or run internal team communications, this chatbot is engineered to do exactly that — without relying on third-party API middleware that adds cost, complexity and potential failure points.
**What Your Chatbot Can Do**
Every chatbot is custom-built to your use case. Common applications include:
- Customer Support and FAQ Assistance — handle routine enquiries around the clock without human intervention
- Appointment Scheduling and Reminders — let customers book and receive confirmations automatically

- Surveys and Feedback Collection — gather structured responses at scale
- Promotions and Personalised Recommendations — deliver targeted messages based on customer input
- Event Management and Registration — manage sign-ups and send reminders via WhatsApp
- Internal Team Communication — streamline collaboration with automated workflows
**How It Works**
Once you place your order, share your requirements via the order chat. The development team will review your use case, ask any clarifying questions, and begin building your tailored solution. The chatbot is developed using GPT-4 AI and integrated directly with your existing WhatsApp setup — no third-party API required, keeping your stack clean and your costs lower. Delivery is provided within the agreed timeframe, with a revision round included so you can request refinements before sign-off.

Frequently Asked Questions
Yes, you will need an active WhatsApp Business account to integrate the chatbot with your WhatsApp presence. If you are unsure about your current setup, share the details in the order chat and the team will advise you on what is needed before development begins.
The chatbot is engineered to integrate directly with your WhatsApp system rather than routing through an additional third-party middleware layer. This keeps your technical stack simpler, reduces ongoing costs, and removes a potential point of failure in your automation.
After placing your order, describe your use case as clearly as possible — what you want the chatbot to do, who it will serve, any specific responses or flows you have in mind, and any relevant details about your business. The more context you share, the more precisely the chatbot can be tailored. If anything further is needed, the team will follow up via order chat.
The Starter package is optimised for a single focused use case to ensure quality and clear scope. The Boost and Premium packages support multiple use cases and more complex conversational flows within a single chatbot solution.
Once the initial build is delivered, you review it and submit your revision requests through the order chat. Each package includes a set number of revision rounds as stated. Additional revision rounds can be purchased as an add-on if required.
The chatbot can be customised for virtually any industry — including retail and e-commerce, healthcare and clinics, hospitality, professional services, events, and internal business operations. The solution is always tailored to your specific use case rather than built from a generic template.
This service is focused on WhatsApp automation. If you have requirements for other social media or messaging channels, mention this in your order details and the team will advise on what is feasible within your chosen package.
