The corporate travel software firm, Serko, is expecting its March year revenue to be 4 to 6 percent lower than the $11 million dollars forecast in May last year.
The company said the shortfall was due in part to the delayed launch of Serko Mobile.
But it said the primary reason was some billable services' revenue being moved to the 2016 financial year.
Serko said its full-year operating loss was expected to be in line with its previous guidance.
It will release its annual results in late May.
