What an AI chatbot does for a small business
- Never misses an after-hours enquiry. Prices, opening hours, location and policies are answered at 11 pm and on Sundays.
- Captures leads automatically. Name, phone, email and need go straight to your inbox, spreadsheet or CRM.
- Qualifies before your team calls. A few questions separate ready buyers from browsers.
- Hands over at the right moment. Complaints, complex questions and ready buyers go to a person, with a summary.
- Frees your staff from answering the same ten questions all day.
Why small businesses lose customers in chat
- Replies take hours, and the customer has already contacted a competitor.
- Staff answer differently, and customers get mixed information.
- Contact details from chats are never recorded.
- Simple rule-based bots frustrate customers with rigid menus.

Frequently asked questions
Will the chatbot give wrong answers?
We build from your approved information, set limits on topics the bot will not answer and route uncertain questions to a person. We test before launch and review real conversations monthly.
Can the chatbot speak Vietnamese and English?
Yes, depending on the model and your content. We test each language before launch.
Do I need a website to use a chatbot?
No. A chatbot can run on Facebook Messenger or Zalo OA without a website.
Can you guarantee more sales?
No. We commit to a defined build, testing before launch and monthly improvement based on real conversations.
Limits and honest expectations
A chatbot is only as good as the information it is given, and some questions should always go to a person, especially medical, legal and financial advice. Platform pricing and features change, so third-party costs are confirmed at the time of quoting.
