Stop losing track of your regulars. This simple Google Sheets customer list template lets you record: name, phone number, Instagram handle, birthday, last visit date, what they bought, and personal notes (allergies, preferences, sizes). Includes a basic search guide so you can find anyone in seconds. Birthday reminder tab shows who has a birthday this month so you can send a personal message. No apps, no subscriptions — just your own private list that lives in your Google Drive.
