# 🏬 Core concepts: stores and multi-store publishing

Peak PIM is built to manage one catalog across several Shopify stores.

# The key idea

You keep one product in Peak PIM, but each store can show its own version of it. The same t-shirt can have a different title, description, price or tags in each store, while still being a single product you manage in one place.

# How publishing works

When you're done editing, you choose which stores to publish to. Stores you don't select stay exactly as they are.

This lets you tailor your catalog per store without ever duplicating your work.
