Overall most retailers are pleased with the latest retail figures released by the Australian Bureau of Statistics (ABS). It shows a moderate increase. The report itself is available here.
Now since this is coming out in excel, what you might want to do is merge your figures with an appropriate set of figures from this report to see how you compare with an average appropriate to you.
This you can do as unlike most point of sale software that can only produce standard reports, which works about 80% of the time. Ours has ad-hoc reporting so all you need to do is export your information into a spreadsheet and put it into the Australian Bureau of Statistics report.
If you have Microsoft Excel, you can use that, or you can use the free OpenOffice available here, both as very good.
If you are unsure how to the export here is a training video which shows you how to do these exports.
