As part of their Second Quarter Earnings Report on February 25th, Intuit announced that the total number of QuickBooks Online subscribers had increased by 49% "to 1.257-million customers worldwide as of January 31, 2016."
Shortly thereafter it was also announced that within the United States alone, "the number of QuickBooks Online subscribers had broken the 1-million mark."
Based upon these strong subscriber growth trends, Intuit raised their subscriber outlook for the remainder of fiscal year 2016 from 1.475-million to 1.5-million subscribers.
Certainly looks to me like, 'QBO is on the grow.'
