The BRC-KPMG Online Retail Sales Monitor (ORSM) is an accurate monthly measure of online retail sales performance that acts as both a benchmark for participating retailers and as an economic indicator.

The ORSM measures changes in the actual value of non-food transactions which take place over the internet, or via mail order or phone, based on figures supplied directly by participating members. It is a guide to the growth of non-food sales made by all non-store channels. It provides a greater understanding of the way in which online is changing the way we shop.
