Setting up multi-store functionality in Magento 2 is one of the platform’s strong points, and it’s fairly straightforward once you understand the basics. Magento allows you to manage multiple stores with different domains, languages, or currencies, all from a single backend. The main challenges could be configuring the correct settings and ensuring performance isn’t impacted by the additional load. Extensions like amasty FAQ from Amasty can help optimize multi-store setups, making it easier to handle inventory, orders, and shipping across different regions.
