Call centre software provider Netcall has ramped up both revenues and earnings during the year to June as customers gained confidence. The company enjoyed an upsurge in its second half which it attributed to a recovery in the private sector and orders for its business process management and software-as-a-service (Saas) products. Chief Executive Officer Henrik Bang said the board now expected to report adjusted earnings before interest, tax, depreciation and amortisation "comfortably" in line with expectations" for the full year, with a "significant increase" in revenue and adjusted earnings. Bang explained that as Saas orders are an increasing proportion of new business, Netcall has looked to take advantage of this by enlarging its Saas-based Liberty customer service platform. "We have built a larger and more diversified pipeline and continue to move forward with investment in our Saas capability and product suite; which together with our strong balance sheet, positions Netcall well for the future," said Bang.The companny said the Liberty launch has been well received, with many customers upgrading, while September 2012 acquisition Serengeti Systems has been reorganised and integrated, and is creating "incremental opportunities" from the group's existing customers.Shares in Netcall were up 3.8% at 41.25p by 16:20 on Thursday.
