Lumen Electrical Co.

A licensed home-services company: rates, coverage area, booking lead time, and emergency call-out — no catalog or shipping fields.

Willowbrook Family Clinic

An appointment-based clinic: hours, booking, insurance, and a hard rule that symptoms never get an automated medical answer.

Field & Ember Outfitters

One sample of selling goods: products, prices, shipping, stock, and optional cash-on-delivery for pickup — not required for other businesses.
