Companies using an ASP could avoid being overcharged by using a new software tool which may lead to pay-per-use services.
ASP Usage Manager, developed by application management and usage supplier Emerald Lizard, will allow ASPs to keep an itemised record of the application and software used by large corporate customers.
While the ASP market has shown sharp growth over the past few years, there is still widespread scepticism among IT managers over the benefits of using an ASP service.
Analysts said Lizard's product could fill a gap in the market where ASP billing is based on flat-rate charging. But they also warned that the complexity of the pay-as-you go charging model would only make it worthwhile for larger users.
ASP Usage Manager can monitor applications that run on a Windows Terminal Server or a Citrix operating system.
Graham Titterington, senior consultant at IT analyst Ovum, said, "They are probably on to a winner but the installation and complexity of use for ASPs could be passed onto the user."
