When you record the receipt of rent from tenants, while this money is passed to the landlord as rental income, in most cases, a percentage-based management fee will also be applied to the landlord (although this depends on your agency configuration).
However, if you subsequently delete the tenant receipt, this management fee is not automatically deleted from the landlord's account. This obviously has the potential to leave "orphan" charges which may no longer be valid, but which will require manual intervention to clear off the landlord's account. If you subsequently re-add the tenant receipt, this will result in multiple charges. A new warning has been added in the delete confirmation box advising that the fee will need to be removed separately.
These orphan property management charges, whose "parents" have been deleted are now highlighted by a red alert icon in the list of charges, as well as on on-screen statements; they are hidden on printed statements. Rather than having to look through all properties, there is also a new Orphan Property Management Fees report available via Reports > Accounting which will highlight any such charges across your entire account.
If the charges have not been paid you can simply remove these by viewing the charge and clicking Options > Delete. However, if the charge has been paid you may need to click on the charge receipt and remove the payment, which will put the money back on the landlord's account and allow you to then delete the charge. Alternatively, if the landlord is already aware of the duplicate charge you may apply a credit note to the property.
We may revisit this in the near future to remove fees where possible, and only leave those which have had payments received, but for now no management fees are automatically removed by the system so these alerts and reports will highlight those you need to be aware of.
