Note:
There is often a legal requirement for a company to display certain information about their company on official documentation.
For example in the UK a limited company must show their registered office address, company number and where the company is incorporated. Also if registered for VAT the VAT registration number must also be shown. This is not an exhaustive list and it is your responsibility to ensure that the documentation produced by BusinessFlow meets the legal requirements of your country.
