There are two levels of unit of measure for items in Point of Sale.
Single Unit of Measure (Basic)
A unit of measure can be added to item records and can then be used to filter and sort your item list and reports.
For example, a candy store might define units of measure of "ounces" and "lbs" and then assign one of those units to each of their candy items.
Define the allowed units on the Inventory page of company preferences.
Multiple Units of Measure (Pro)
Using multiple units of measure allows you to purchase and sell items by different units. For example, when you purchase an item by the case but sell it by the bottle, or buy in bulk but sell by the pound.
Select the I Want to set up multiple units of measure… checkbox on the Inventory page in company preferences to enable this feature. Then, on the item record, you can define a base unit of measure and up to three alternate units that you buy or sell by (such as case, six pack, can, 100 lb bag, one pound, etc.). Each unit of measure can have a different UPC code, alternate lookup value, and sales price, allowing you to list any of the units of measure on documents. You can also specify your default purchase and sell-by units.
If the multiple unit of measure feature is turned off, you still retain the single unit of measure capability.

If importing item information, you can import the unique information for each of your units.
