Serve customers across 13 locations on WhatsApp and Instagram with an OpenClaw agent

The owner of a 13-location sauna chain built Lucy, an OpenClaw assistant running on his own Mac mini, connected to WhatsApp, Instagram, Slack, Gmail, the Reenio booking system and Trello. She answers questions, checks availability, applies compensation rules and escalates complaints. He swapped an expensive model for MiniMax-M2.5 via OpenRouter.

How it works

  1. Install OpenClaw on a local machine and connect WhatsApp, Instagram, Slack and Gmail.

  2. Integrate the booking system and the task board (Reenio and Trello in the original case).

  3. Write strict rules: FAQ, when to apply compensation and when to escalate to a human.

  4. Set up long-term memory and daily logs for the agent.

  5. Track the monthly cost and switch to a cheaper model if quality stays good enough.

You are Lucy, the customer service agent for our sauna chain. Answer questions about opening hours, prices and locations using only the FAQ base. For availability, check the booking system before answering. Apply compensation only according to the rule (50% off or free entry) and forward to a human any complaint with a photo, request outside the rules or complex case, with a summary of the problem.

Reported result

Instant 24/7 service across all 13 locations and about 10 hours a week saved, with model costs dropping from over $200 to about $20 a month after switching to MiniMax-M2.5.
