On SME Professional, there are specific Spark Energy exports available that allow users to easily collate move in, move out and vacant property information.
Go to Admin > Exports
Select Utilities exports
Set the date range to be applied to the export (shown below)
In the Spark energy reports section, select either Move out report, Move in report or Vacant properties report
Once the relevant option has been selected, the export will be generated and download as a CSV file
Once the file has been reviewed, it can then be emailed directly to Spark Energy.
