I have two different payment methods?
I use my id for personal and business. Can I split my purchases into two different payment sources?
Keep your private primary Apple ID separate from your work Apple ID.
A business Apple ID is usually name@ company.xxx
With a managed ID you have many limitations, such as:
App Store is disabled and its icon is removed from the Home Screen.
The iTunes Store is disabled and its icon is removed from the Home Screen.
Users can't make in-app purchases.
For private, you can have a credit card / debit card on file and an Apple Account balance.
Your default payment method will be used first by Apple when you need to make a payment.
If you have set your Apple Account balance as your default payment method and you have a CC / debit card, you pay from your default payment method.
If you have 2 CC, and you have set one CC as your default payment method that will be charge by Apple.
