It's currently possible to record manual/offline payments for rental fees/surcharges/taxes but not possible to do that for security deposits. Ideally we'd be able to do that for security deposits as well and have the security deposit status updated when that happens (so that any triggers based on security deposit status are properly evaluated).
As an example, for longer-term guests we often will accept check as a payment method and the guest will include the security deposit in their check amount for the regular booking fees. If we record the security deposit as an offline/manual payment, that over-reports the revenue (and reports we use for sales taxes/other monthly reconciliations are skewed/inaccurate).
