This feature will automatically calculate the extended weight for each line in an invoice, sales order or estimate (quantity X unit weight), as well as a total weight for the order. Note that only the item types that were selected in the Order Preferences earlier will be included in these calculations.

Select Enable if you wish to use this feature.
The Weight feature requires three custom fields:
• Unit Weight: You will store the unit weight for the item in this field – it will be a “custom field” in the Item List. The dropdown list will show you the existing custom fields (if any) that you have defined for items. If you have already defined one for the unit weight for items, select that. If there is room to add another field (the limit in QuickBooks is five custom fields in the item list) then the wizard will add the choice “Unit Weight” to the list of fields. If you select this, and it hasn’t been defined in QuickBooks already, the program will create it.
• Extended Weight: You won’t store information here – we need a place to store the calculated weight for each detail line (quantity X unit weight). This is added to the item list – select “Ext Weight” if it shows, rather than using one of your existing fields.
• Total Weight: This is the custom field to hold the total weight for the order. This is added to the customer list. You can select an existing field, or “Total Weight”.
