How can I add a summary line or description onto an invoice?

Sometimes, when entering multiple items on separate lines onto an invoice you may need to output a summary description, e.g. saying something like:

"The following items were charged for work done on X date as agreed with person Y"

If you want to include a summary line like this you won't want SliQ to output any figures for quantity, each or total when the invoice is printed. To make SliQ leave the figures off for a summary item, simply set the Quantity field value to 0.
