Selling Products Individually and in Groups
To set up a unit group, you must determine a primary unit. The primary unit is the lowest common unit of measure for the unit group.
Next, you must decide how the inventory will be sold, such as by the individual item, a dozen, or a case, or by the hour, week, or project. Each of these types of measurement is referred to as a unit. Each unit is defined in terms of any other unit in the unit group. A unit group is comprised of units that are related to each other.
After you determine a primary unit for a unit group, you can set up larger quantities that can be packaged. Unit groups define how the different base units relate to one another.
When you determine the primary unit for a unit group, you should use the most common unit of measurement that your product or service will sell.
