The conversion date is effectively the system start date, the date from which you will start entering your day-to-day transactions into the new system.
You should only have rent, charges, receipts and payments that occur after this date in ShowHouse. Any activity occurring before this date should be reflected in balances from your previous property management or accounting system, and you can provide details of your outstanding rent and charges to ShowHouse as conversion balances to allow them to be processed into the new system.
By default the conversion date is set to the day the trial was set up. You can change this later in the Settings area via Agency Settings > Financial > Conversion Date.
The conversion date cannot be changed once accounting transactions have been entered into ShowHouse.
