In the event a Commercial/retail tenant has a rent-free period, if a credit is applied to an existing rent invoice, this is not recorded or reflected in the tenant ledger effectively. If a new employee was to take over, the ledger is extremely difficult to see if there was ever a credit applied, it just shows a lot of cancelled invoices and replacement invoices. A reason for the rent credit is requested when entering but is not noted down on the ledger once entered. The reason is only recorded on residential ledgers not commercial.
