Customer and lead records allow you to record the number of employees for that company.
These numbers can be stored in three different formats. This can be set company-wide from Settings - Company Setup, with the Employee Number Type setting.
The options are as follows:
List Options
This lets you select from a number of fixed ranges
Value
This lets you enter a specific number against each record
Custom List Options
This lets you select from a number of ranges that you determine
If you select Custom List Options and save, you'll see a link to the area that lets you define the Employee Ranges.
Custom Employee Ranges
This can also be accessed from Settings - Custom Employee Ranges.
Here you can add employee ranges. You can also edit or delete existing ranges, though this should be done with caution.
Ranges cannot overlap, and there should be no gaps between them.
