Many small and medium-sized business owners use preprinted purchase orders, order acknowledgments or delivery receipt forms. Many of these forms can be obtained on the internet. However, while convenient, the forms are dangerous to use. Many of the preprinted forms obtain on the internet or from forms providers come with detailed legal terms written in small print on the back of the form. This is usually called "boilerplate language." However, it can get the user in trouble if not used properly.
