Profits plunged at Netcall in the first half, but the queuebuster call-back software company has made an "encouraging" start to the second half.Profit before tax sank 77% to £102,400 during the six months to 31 December, down from £438,600 in 2008. Before non-operating costs and tax it fell 35% to £350,000.Revenue dropped 7% to £1.86m, but recurring revenue from hosted platforms and maintenance & support agreements grew to £1.6m, representing 87% of the overall revenue. Results benefited from October's acquisition of Q-Max for £2.5m."Netcall's start to the second half of the year has been encouraging with early sales combined with a strong pipeline," said boss Henrik Bang. "It is expected that the full year results will show a bias towards the second half due to longer sales cycles relating to general market conditions.""Whilst market conditions remain challenging, the board remains confident of a successful outcome to the year."
