Sub-Accounts allow you to have multiple user logins under one user. This allows you to switch back and forth between accounts without having to login each time.
Common uses for sub-accounts are monitoring your children's spending, keeping personal finances separate from your business expenses, or giving family members their own account to use. Once subscribed, each sub-account is also a subscribed account so they can take advantage of features like charts, unlimited data entry, and File Storage.
The Co-Branding feature allows you to brand the BudgetTracker site as your own anywhere from adding your logo and colors to creating your own links.
The Co-Branding feature differs from sub-accounts in that you have the ability to completely customize the experience for your users which includes changing the Logo, Colors, Fonts, Links, which Tabs to show, and an exclusive Social Network that only the users of your brand can communicate in.
