Capital Accounts

First, you need to update your software. Cash in hand, as a separate module, was discontinued long ago. All cash account, whether in hand or in bank, are now under the single Cash Accounts tab.

Second, before you can enter any cash transaction, you must create the relevant cash accounts.

Third, cash transactions can only be entered under the Cash Accounts tab, not as Journal Entries.
