[Customers](https://docs.kentico.com/k9/e-commerce-features/managing-your-store/customers.md) may want to change the information you store about them. For example, they may want you to change their addresses. Alternatively, if your customer is a company, they may want to change their contact person's name.

> **Info:** If you need to modify a customer's details in an existing order, you need to change the order's attributes. Learn more in [Orders](https://docs.kentico.com/k9/e-commerce-features/managing-your-store/orders.md).

With the following process, you can change the customer's:

- First and last name

You can also [create a user account](https://docs.kentico.com/display/K9/Registering+customers) for such customer. With a [user account](https://docs.kentico.com/display/K9/User+management), the customer can sign in on your website and buy their stuff on their own the next time.
