To create a billable activity, first set specific attributes within the Master Item window. Next, decide whether you are pricing this item using the Cost Plus or Price List method, or both, and perform the additional setup for those methods (See: Setting Up Item Costs and Prices). Finally, associate the activity to the asset group or asset number that is used to create the work order.
Navigate to the Master Item window.
Select the Invoicing tab.
Optionally select the Invoiceable Item check box to indicate that the current activity item can be invoiced. You can select this attribute at the Master Organization level.
Optionally select the Invoice Enabled check box to indicate that invoices are enabled for the current activity item.
Assign the current item to your organization.
Save your work.
