This increase was primarily the result of continued increases in active locations coming onto the platform, as well as increased transaction volumes. Active locations increased to approximately 82,000 as of March 31, 2022 from approximately 69,000 as of March 31, 2021, and ARPU decreased to approximately $516 for the three months ended March 31, 2022 from approximately $525 for the three months ended March 31, 2021. For the three months ended March 31, 2022 and 2021, 50.2% and 41.6% of our platform revenue was subscription revenue, respectively, and 49.8% and 58.4% was transaction revenue, respectively. Professional Services and Other Total professional services and other revenue increased $0.1 million, or 7.5%, to $1.3 million for the three months ended March 31, 2022 from $1.2 million for the three months ended March 31, 2021. While we expect professional services and other to increase primarily as a result of continued deployment of additional active locations, we expect this increase will be offset as our deployment teams become more efficient and shorten deployment periods.
