Aynax offers a fully customizable template, along with the ability to print, download or save the invoice. Users can add purchase order numbers, taxes or discounts and upload their company's logo. International companies can choose from a variety of foreign currencies and languages. The preview feature displays a draft invoice and gives the user another opportunity to make customizations.
