SSP has revised its turnover target to £60m by the end of 2009.
The software provider had set a target of £40m at the start of 2005, but the acquisitions of Sectornet and Insure+ Solutions has improved the company's growth prospects.
SSP's executive chairman, David Rasche, said the new goal was realistic and was based on the successful integration of recent acquisitions into the business and a buoyant market.
Rasche commented: "Approximately £7.5m of our increase in turnover has been organic growth and £12.5m has come through acquisition. We've grown by nearly 50 per cent organically since we acquired the business in 2002 and we are looking to achieve that growth again over the next three years, so to meet our new target we will need a further £15m of acquired revenue."
Rasche also stressed that no decision had been made either way about flotation, which could value the company for as much as £100m.
