Property management bookkeeping goes wrong slowly and is discovered suddenly, usually at a year end or when an owner asks a question. The defence is a short monthly routine run in a particular order, because the order is what surfaces errors while they are still explainable. This page is that routine, for a small operation without a bookkeeper.
First: reconcile the bank, all of them
Operating, client and deposit accounts, each against its own ledger, every month. Doing this first is deliberate: almost every error eventually shows up as a bank difference, and finding it here means finding it before it has been built on. A reconciliation that will not balance is information, not a failure, and it is cheapest to chase within the month.
Second: rent charged against rent received
For each tenancy, what should have been charged this month, what arrived, and what the balance is. This catches the payment that was received and never recorded, the charge that was never raised, and the tenant quietly slipping into arrears. It is also the point at which receipts should be issued if they have not been.
Third: expenses coded to the property
Every invoice against a property and, where it matters, a unit. Coding at the point of entry takes seconds and reconstructing it at year end takes days. This is also where a markup or a management fee should be recorded as your income rather than netted off silently, because netting is what makes your own accounts unreadable.
Fourth: the exceptions list
Anything unexplained: an unallocated payment, a deposit that does not match a tenancy, an invoice with no property. Keep it as a short list rather than resolving each immediately, and work it before the next month's routine. An exceptions list that grows month on month is the signal that the routine has stopped working, which is worth knowing early.
Questions people ask about property management bookkeeping
How long should this take?
For a small portfolio, an hour or two a month once the routine is established. The first few are longer because they surface a backlog.
Do I need a bookkeeper?
Not necessarily, and you do need the routine. A bookkeeper who receives clean coded records costs far less than one who receives a shoebox.
What about the tax year end?
It stops being an event if the monthly routine has been kept. The IRS sets out what a rental owner is expected to show, and a per-property record produces it directly.
