How can I itemise invoice line items, i.e. number them?

When entering items onto an invoice you can leave the item code field blank and just type in a description, quantity and each value.

In SliQ Invoicing Plus, you can edit your invoice template and include an item number column on the printout/ email. The column won't appear while editing but will show when you print etc. For help on customizing columns, take a look at this page:

After checking the box to include an item number column, SliQ will automatically number each item you add to an invoice. The default heading for the item number column is #, but using the invoice template editor you can change the heading of the column as well as adjust its width. See these links for more info:
