So when transferring money between bank accounts where the bank changes a fee for he service. This is entered into Manager by splitting the transaction into two Manager transactions
The money which gets to the second account
And also a fee transaction
I suppose the convenience to having a single Manager transaction for inter account transactions vs splitting out the components would depend on how the data is received / entered and the reporting requirements (who is bearing the cost of the fee; the business or is it passed on to the customer).
These considerations maybe important when Manager adds support for bank import of inter account transfers and the associated transfer amount matching. Ability to convert two transactions to a Inter Account Transfer
