This option is applicable if you are running a business, or selling reptiles. If you are keeping a reptile as a pet or have no intention of breeding reptiles then this section can be skipped and left as default.
Custom Fields – There are 3 custom fields available for use in the Invoices module. As in other modules we have included these just in case you have a specific item you wish to record which has not already been covered. Here you can enter the label text for each of those fields.
