In certain use cases it is preferred not to have certain items printed on client invoice.  SpecVet has a feature where  items can be "invoiced" but not show up on printed invoice

Examples use Cases:

• You bill for  the euthanasia service but don't want the amount of euthanasia solution to be shown
• You use a bill code to indicate that charges above a certain date point have been entered and audited

You would manage this in the items table under the "billing tab"

There is a grey check box called "Include on Invoice"

When checked (which would be the default action) item will print on client invoice

When unchecked item will not print but be visible on user screens
