The National Computing Centre will this week help launch an IT quality standard for SME IT suppliers.
The NCC says SMEs are wary of purchasing technology because they have no way of knowing whether a supplier will be able to fulfil its promises.
It said that SME technology suppliers find it hard to get on big company purchasing short-lists because they have no independent mark of quality assurance.
NCC partner AccreditUK aims to solve these problems by creating a quality mark that both groups value.
The AccreditUK standard has been piloted over the last year and those pilot organisations have now become accredited.
The scheme has been trialled in the West Midlands and will now be launched nationally.
The scheme will be launched at the National Motorcycle Museum in Birmingham this Thursday.
