You start by sending what you already have. That can be a list of your ten best-selling products, a spreadsheet with customer, product, and purchase date, or a simple description of your catalog, like pet food, litter, treats, and grooming products.
The AI sorts items that tend to get bought again, ones that pair with another product, and ones with no predictable restock pattern. Then it suggests when to reach out and flags whether that estimate has high, medium, or low confidence.
For example: if a customer bought a bag of pet food on a given date, you get a suggestion for when to reach out and a message like: "Hi! The pet food you picked up should be running low. Want me to set aside another bag for you?"
You don't need to load your whole catalog. Start with the products that sell the most or need frequent restocking, copy the table into your spreadsheet, and check the contact list each week.
