Payment methods

[mtotschnig]

Even without being able to export the payment method into the QIF file, I think it makes sense to add payment method as a data field to the interface. The following methods could be predefined and translated to the supported locales:
Cash
Cheque
Credit card
Deposit
Debit
Users will be able to define additional methods
A new transaction should have the last payment method used with the current account preset.
