Remco When you want a business account, you have to create a "business easy money". After you create it, you can add it to your pack.
You can be logged in to your business account and personal account at the same time. To manage this, long press the "Profile"-button at the bottom. You can also merge your personal and business account after you create it.
PS: The personal account and the business account are not monetary account. Within your personal (or business) account, you can create multiple monetary accounts, each with their own IBAN.
To summarize: Within your pack you have an "easyMoney" and and "easyMoney business", merged together or not, and within your "easyMoney" and "easyMoney business", you can have one or more monetary accounts (up to 25).
