You can add up to five (5) custom fields for items. The fields will be available for all item types except subtotals, sales tax items, and sales tax group items. After you've added the custom fields, you can add them to customized forms.
Learn more about custom fields
Custom fields let you add to the information that QuickBooks tracks about
your customers, vendors, and employees, and the items that you purchase and
When you set up custom fields for items, QuickBooks adds your
custom fields to the fields you work with when you set up new items or make
changes to existing items.
You can also add your custom fields, which appear as additional columns, to your customized forms. The information you enter in a custom field transfers automatically to any customized form in which the custom field appears.
For instance, if the custom field is named "Color" and you entered "navy blue" as the color of a particular item, the Color field on your customized form prefills to "navy blue" each time you enter a sale of the custom item.
