What types of financial accounts should be created as Bank Accounts?

Most obvious, of course, will be current or deposit bank accounts and credit cards.

If there are cheques/checks written on the account then you should certainly operate it as a Bank Account for reconciliation purposes alone.

Other accounts to consider may be: loan, lease, hire purchase, PayPal accounts, etc. or even petty cash.

As you'll notice, you can classify Bank Accounts as any kind of Asset or Liability class. This is done purposely to allow complete flexibility as to what accounts you want to operate as a Bank Account.
