The customer asks, the bot closes the order — and the business runs.

Case study by Achiya Cohen, founder of Achiya Automation

A WhatsApp bot for a business that sells over messages: it answers questions from a business info document the owner updates themselves in Google Docs, recognizes returning customers against a table, takes orders in a natural conversation — and knows when to throw up its hands and hand off to a human rep.

Before & After

Orders stuck on the phone A natural conversation, a tidy order

Before
  • The business owner answers the same questions over and over — prices, availability, deliveries
  • Orders jotted on notes and in chats — they get lost
  • A returning customer is treated like a stranger
  • When they're busy — customers simply get no answer
After
  • The bot answers from a business info document — prices, products, policy
  • Recognizes a returning customer against the customer table and tailors the conversation
  • Takes a complete order and summarizes it neatly
  • Complex case? Hands off to a human rep with all the context

Here's how it works inside

A description of each flow, with identifying details removed.

FLOW · 01

Message → customer recognition → AI → order or rep

Every message is first checked against the customer table — a new customer is registered automatically, a returning customer gets continuity. The AI agent answers from a live business info document (prices, products, terms) that the owner edits themselves. When the customer finishes an order, the bot summarizes it neatly; when the conversation gets complicated, it passes to a rep, and the bot knows not to interfere anymore.
