Total revenue reached about $141 million. But the loss increased to roughly $54 million and reached 56 percent of this year's operating revenue, up from 51 percent in 2014.
Jeffries resignation was jarring as the short-term CFO had been base in the U.S. as part of several steps to shore up management in this country.
"This was a very difficult decision given Xero's momentum and business potential. The decision to leave is entirely based on my personal objectives and the timing is in no way a reflection of business or financial reporting concerns," Jeffries wrote in explaining his sudden exit.
This follows the departure of North American CEO Peter Karpas in September after six months on the job, with management publicly expressing its disapproval of the performance by leadership in this country. Xero has not replaced Karpas in the North American CEO job. However, in a presentation of 2015 results, Xero's slides refer to the U.S. leadership team as being in place.
The company's revenue grew as Xero reported ending the year with 475,000 paying customers, 67 percent higher than the year-earlier total.
The largest number of Xero users are in Australia. That total hit 203,000 at the end of the fiscal year, an increase of 86 percent from 2014. There were 138,000 in its home country, a rise of 35 percent; 73,000 in the United Kingdom, up 77 percent; and 35,000 in North America, a 94-percent increase. The number of subscribers in the rest of the world doubled to 16,000.
Xero's plans for North America include building an online direct sales model. The company will also develop more U.S.-specific applications, although it gave no details.
