Marlin GTX uses Cashbook entries record transactions that do not relate to customer sales or supplier purchases.
Unlike customer or supplier transactions, which are posted to the general ledger at End of Day (EOD), cashbook entries post directly to the account—without waiting for EOD processing—and update the bank account balance as soon as they are committed.
The Cashbook module can be accessed by selecting Main > Data Entry > Cashbook or Bank Reconciliation from the menu bar.

Register deposits and EFT settlements are automatically posted as part of the End of Day Close-Off.
Cashbook entries are therefore typically used for non-trade income or expenses, such as bank fees, interest, or miscellaneous receipts.
Cashbooks can also be used to add missing transactions when performing bank reconciliation.
Deposits entered at the head office can be distributed across multiple locations.
