When a long-term asset like land or buildings is acquired certain cells on the Land and Building Screen as shown below must be entered. You can indicate if you are acquiring the asset by cash or by way of a mortgage bond and you can enter the amount in the install column. It's important to note that if there are existing mortgage bonds you enter the opening figure in the trial balance where space is provided. If the asset is acquired in the first month or prior to the first month then the full amount of the instalment must be entered on the trial balance otherwise it can be entered in the month that the instalment starts.
Enter the opening installments on the trial balance screen as shown below to the right of the trial balance.
