# Custom Data

Custom data lets you store merchant-specific data to Products, Rate Plans, Billing Plans, Season Sets, Subscriptions, Accounts, and Payment Methods as a pair of matched text strings, called name-value pairs. These name-value pairs can help you categorize and sort aspects of your objects. Use **Name** to define a category, and **Value** to define a specific item in that category. For example, you could use name-value pairs to track your sales teams. Define a name-value pair with Office as the **Name** and the city in which the office is located as the **Value**.
