A practical WhatsApp Business auto-reply pack for small shops (no API required)

If you run a cafe, a cleaning service, a clinic front desk, or a repair shop, customers already message you on WhatsApp. The official WhatsApp Business app (the free one, not the Cloud API) lets you set a welcome message, an away message, and saved replies. You do not need a developer or a monthly bot SaaS to cover the first 80% of questions.

This post is the structure I use before wiring anything fancy.

1. Welcome message (under 300 characters)

  • Who you are
  • What you can help with in chat
  • How to reach a human (type /human)
  • Reminder that prices may need an on-site quote

2. Away message

  • When you are closed
  • When you will reply
  • Emergency / urgent path if you have one (or say you do not)

3. Slash quick replies (start with these 12)

/hours /address /services /price /book /cancel /pay /invoice /promo /human /sorry /stop

For /price: never invent a firm number if you quote on-site. Reply with a range or "we confirm after a short checklist" and offer to collect details.

4. Hand-off rules (write these down)

The bot / quick-reply layer must not decide:

  • Medical, legal, or refund outcomes
  • Custom discounts
  • Anything that needs looking at a photo of damage
  • Complaints that sound angry — go straight to /human

5. Tags inside WhatsApp Business

Create tags such as new-lead, booked, waiting-quote, vip, do-not-message. Tag every chat before you archive it.

6. Fifteen-minute go-live checklist

  1. Welcome + away saved
  2. Twelve quick replies pasted and named
  3. /human reaches a real phone that is on
  4. Test from a second phone
  5. Prices language reviewed by the owner
  6. Privacy: do not ask for ID documents in chat unless required
  7. Add a short "AI / template assisted replies" note if your market expects disclosure

I published a ready-made eight-industry version of this pack (cafe, home service, salon, clinic desk, ecommerce, rental, tutoring, repair) on itch.io if you want to skip the typing:

Written with AI assistance; you still own the edits for your shop.
