Sales, Marketing & Support

What they did

The builder wired Instagram DMs from Meta’s API into Claude Sonnet 4.6, giving it a knowledge base for all seven locations: menu items, ingredients, calories, allergens, delivery zones, hours, prep times, promos, and conversation rules. The agent chats with customers, answers menu questions, collects address and quantity, offers add-ons, sends a bank payment link, then pushes confirmed orders to the kitchen and logs them in the CRM and an owner dashboard; humans still handle calls, voice notes, photos, or explicit requests for a person.

How it went

The poster says the agent handles plain-text order chats almost entirely on its own, gets orders right about 98% of the time, and rarely needs human takeover beyond non-text cases. They also say roughly 97% of the large prompt is served from cache, cutting that portion of Claude input cost by about 90%, but allergen mistakes and stale menu data were raised as the key risk.

Worth knowing

The main practical catch is keeping menu and allergen data current; the post says the economics only worked because Claude prompt caching avoided reprocessing the full seven-location context on most messages.
