Why Customize Fields?

Salesforce provides several standard fields in each record. Standard fields are common to most CRM businesses, like company name, contact, account number, status, date, and amount. But every business is unique, and you may want to capture important info that’s not covered by a standard field.

Custom fields are the way to do this. You can create custom fields on standard Salesforce objects or on custom objects. When you create a custom field, you decide where it appears, what info it contains (1), what format it should be (such as number, text, date, or picklist) (2), and who sees it and who can change the field value. 

Data types you can choose to determine the format of a custom field.

Fields can store many different types of data. When you create a field, it’s important to define whether you want users to choose from a predefined list of options or whether you want them to enter raw info. For example, you might offer a common set of values for a custom field with the label Status—new, assigned, in progress, and complete—to track work consistently across multiple accounts. Or you might add a free-form text field for comments or account details that vary from record to record.

  6. Next, choose a data type. Choosing a data type helps you format the field input. For example, if you create a field with the Date data type, users can enter a date or pick one from a popup calendar. Account detail page showing rules and format for a date custom field.

Custom fields make Salesforce work better for you and your business. The total number of fields you can create depends on which edition of Salesforce you’re using. For Enterprise customers, the limit is usually 800 custom fields.
