This looks like what a good web designer with little knowledge of actual accounting requirements would do. Not what I would expect from a company specialising in accounting software. It makes me seriously doubt that they can actually fill my accounting needs, so instead of creating a lead, I can't help having doubts about their capabilities.

The first thing I would expect from such a tool is either to explicitly point out the limitations of the free offer (eg 'only valid for retail in the Netherlands!'), or, if you expect users to believe you are capable of fulfilling their invoicing needs, you have to ask which business sector and which country you are creating invoices for, and actually update the template to suit the legal requirements of the user's domain (taxes, legal mentions, display of business registration, etc).
