• [ ] Prefilled data should be removed (i.e. only Account name and Email should have entries until the user fills them in).
• [ ] Placeholder image that appears under after clicking Edit needs to be displayed correctly.

  • [ ] 'Category' -> 'Organisation name'
  • [ ] 'Box' -> 'Street address (1)'
  • [ ] 'Street address (2)'
  • [ ] 'Organization number' -> 'Town/city'
  • [ ] 'State/region/county'
  • [ ] 'Postcode/zipcode'
  • [ ] 'Country'
• [ ] Remove 'Street address' and 'Town/city' from General information section, as redundant with Billing information.
