Website and WhatsApp chatbots
AI chatbots that answer customers and know when to hand over
TechZone Services provides AI chatbot development services for websites and WhatsApp, building assistants that answer from your approved content, capture and qualify leads, and pass conversations to your team when a person is needed. We connect each chatbot to the tools you already use and test it on your real customer questions before it goes live.
Chatbots with guardrails
A good chatbot answers well or steps aside
Most customer questions repeat: prices, delivery areas, opening hours, order status, how to book. A well-built chatbot answers these at any hour from your own approved content, collects the details your team needs, and hands over to a person when a question falls outside what it knows. Our AI chatbot development services cover the full build: the knowledge base, the conversation design, the integrations and the testing that decides whether it is ready for customers.
We build chatbots for your website and for WhatsApp through Meta’s WhatsApp Business Platform. Each bot is grounded in your content, so it answers from your FAQs, policies and service or product details instead of guessing. It is designed to admit when it does not know and route the chat to your team, and anything high-stakes stays under human review. For other places AI can help, see our guide to AI in digital marketing for small business.
This service is part of our wider AI solutions work and follows the same rule: start with one clear job. If a simple menu, a form or a rule-based flow would serve your customers better than an AI model, we will say so before you spend money on something more complex. Our guide to choosing a realistic first AI project explains how we make that call.
Ideal for
- Businesses answering the same questions daily
- Teams handling inquiries on WhatsApp
- Service firms that need leads qualified
- Stores fielding order and delivery questions
Challenges we solve
Why many business chatbots disappoint
The AI model is rarely the problem: weak content, no route to a person and no testing before launch cause most failures.
Confident answers that are wrong
A chatbot connected to a language model without your approved content can invent prices, policies or availability. One wrong answer about a refund or a delivery date costs more trust than the bot will ever save.
No way to reach a person
Customers stuck in a loop of canned replies leave or complain. WhatsApp’s own Business Messaging Policy requires businesses that automate replies to offer clear escalation paths, such as a transfer to a human agent.
Leads that go nowhere
A bot that chats but never records a name, need or phone number, or stores them somewhere nobody checks, adds another inbox to watch instead of handing your sales team qualified inquiries.
Unclear handling of customer data
Conversations often include names, phone numbers, order details and sometimes health or financial information. Without clear rules on what is stored, where and for how long, a chatbot quickly becomes a privacy risk.
Our approach
How we build chatbots you can trust
We start with the questions your team actually receives, taken from your inbox, WhatsApp chats and call notes, and agree what the chatbot should and should not handle. We build its knowledge base from content you approve, choose a model based on accuracy, cost and privacy needs, and test it against real questions before launch. After go-live, we review conversations with you and fix gaps in the content rather than letting the bot guess.
- Scope agreed from real customer questions, not assumptions
- Answers grounded in content you have approved
- Clear handoff to your team for anything outside scope
- Only the data the chatbot needs, kept as long as you decide
- Tested on real examples before any customer sees it
What's included
What's included in our AI chatbot development
Every chatbot is scoped to your business, connected to your tools and tested before launch.
Knowledge-base answers
We organize your FAQs, policies, service pages and product information into a knowledge base the chatbot answers from, with source references so your team can check where each answer came from.
Chatbot for your website
We add a chatbot for website visitors on WordPress, Shopify or a custom-built site, styled to your brand, with suggested questions and a clear option to contact a person at any point.
WhatsApp chatbot for business
We connect a chatbot to your number through the WhatsApp Business Platform, using message templates where Meta requires them and following opt-in rules for any message you send first.
Lead capture and qualification
The chatbot asks the questions your sales team would ask, such as the service needed, location, budget range or timeline, and sends complete lead details to your CRM, email or spreadsheet.
Human handoff
When a customer asks for a person, gets frustrated or raises something outside the bot’s scope, the conversation passes to your team with the full chat history, so nobody has to repeat themselves.
Integrations and reporting
We connect the chatbot to your CRM, booking system, helpdesk or online store, and set up conversation logs and reports that show common questions, unanswered topics and how often chats are handed over.
01
Honest scoping
We tell you which questions a chatbot can answer reliably and which should stay with your team. If a form or one of the simple workflows in our marketing automation guide would work better, we say so first.
02
Privacy decided up front
We map what personal data the chatbot collects, limit what is sent to the AI provider, and agree retention and deletion rules with you. Where possible, we use API options that keep your inputs out of model training.
03
Engineering, not just prompts
Our Python developers build the integrations, databases and admin tools around the model, so your chatbot is maintained software with logs and access controls, not a prompt pasted into a chat widget.
04
Your accounts, your data
Your WhatsApp Business account, Meta business portfolio, AI provider account and conversation data stay under your ownership. We work through access you can remove, and hand over code, documentation and admin access.

How it works
How we take a chatbot from idea to launch
01
Discovery
We collect a sample of real customer questions and agree the chatbot’s job, the topics it must never answer, and where conversations go when it hands over.
02
Content and data
We gather and tidy the content the bot will answer from, agree privacy rules, and decide which personal details it collects and where they are stored.
03
Pilot build
We build a working version on a staging page or test WhatsApp number, compare candidate models on your real questions, and share the accuracy results openly.
04
Guardrails and testing
We add fallback replies, handoff rules, usage limits and logging, then test with your team, including awkward and off-topic questions, before any customer sees it.
05
Launch and review
We go live, review conversations with you over the first weeks, fix content gaps and adjust handoff rules, then agree how ongoing monitoring will work.

FAQ
Questions we often hear
Can’t find what you’re looking for? Send us a message and we’ll answer it directly.
Will the chatbot give customers wrong answers?
No AI chatbot is right every time, so we design around that. The bot answers only from content you approve, logs the source behind each answer, and hands over to your team when a question falls outside that content. We test it on real questions from your business before launch and share the results, so you decide when it is ready.
Can we use an AI chatbot on WhatsApp?
Yes, through Meta’s WhatsApp Business Platform. Meta’s terms restrict AI companies from offering general-purpose assistants on the platform, which is different from a business using a chatbot to serve its own customers. People you message first must have opted in, and messages outside the 24-hour customer service window use templates Meta reviews. Our WhatsApp guide covers the rules.
What happens to our customers' data?
We agree the data rules with you before building: what the chatbot collects, what is sent to the AI provider, where conversations are stored and when they are deleted. Where possible, we use API options that do not train on your inputs, mask sensitive details and keep logs in systems you control. We also recommend having your privacy notice reviewed to cover the chatbot.
Can the chatbot hand conversations to our staff?
Yes, and we treat handoff as a core feature. You decide the triggers, such as a customer asking for a person, a complaint, a high-value inquiry or a question the bot cannot answer. The conversation then passes to your team inbox, WhatsApp or helpdesk with the full history, and outside working hours the bot can collect details for a callback.
What does an AI chatbot cost to build and run?
A website chatbot starts from $150 and a WhatsApp chatbot from $200. The build depends on channels, integrations and how much content needs organizing. Running costs include AI provider usage fees and, on WhatsApp, Meta’s messaging charges plus any partner fees. We estimate usage during the pilot with your real volumes and set out the build cost in a written proposal. See our pricing or book a free call.
