# New Languages for Checkouts, Proration for Plan Swaps, Refund Controls, & More ## Language Options for Your Customers Give customers a more seamless experience by letting them interact with your business in their preferred language. Set your account default language in _Company Settings_ for your checkouts, customer portal, affiliate pages, and transactional emails, with support for **English, Spanish, French, and Italian**. [Learn about Default Language settings](https://university.spiffy.co/account-settings/default-language.md) You can also force a specific supported language on a checkout with URL parameters. Customers whose browser prefers a different supported language will be given the option to switch while viewing your pages. After they make a purchase, their customer portal and emails continue in the same language, creating a more consistent experience from checkout through post-purchase.

These can be turned on or off and edited in Customer Notification Settings.
