Mark rent received, and send a reminder when it has not arrived.

Open a property's Finance tab and click Rent status (or click the property from the portfolio Rent status page). This is where you record a rent payment and, if it has not arrived, send a reminder. The picture above shows it.
The Chasing panel shows every reminder already sent and when.
When the balance has not moved, it recommends sending another and gives you a Chase rent button — one click sends the tenant a reminder in your name.
You are never chasing blind: the history is right there, so you know whether this is the first nudge or the third.

The Payments table below lists each month as received, due or overdue.
When rent arrives, mark that month received — the outstanding figure drops, any open chase closes itself, and the payment flows into the property's Finance and your tax estimate.
