Fiscal Invoicing
We are an IT company with lots of experience, though only recently a member of Freelancer.com. We provide professional software design and development services. We have several years of experience designing, developing and administering web, desktop and mobile applications on all major platforms in a variety of languages.
We have read your list of requirements and we don't believe it is a difficult task. Please contact us on PM so we can clarify more aspects.
We have already worked on a invoicing app that uses HTML to generate the invoice PDF. If you want, we can implement something similar.
We are looking forward to collaborating with you.
