The move follows trials of 1Link and will enable Interleasing to source, order and track online all vehicles provided by its network of 200 preferred dealers.
The system was launched by automotive software specialist Epyx and is designed to simplify the new car ordering process for large fleets and leasing companies, as well as for franchised dealers, using the internet to link contract hire and leasing companies with dealers.
Monika Winterbourne, Interleasing's procurement director, said: 'Interleasing and its clients will benefit from a quicker and more efficient vehicle ordering process that can be fully audited, reducing the potential for errors.'
Greg Connell, Epyx managing director, said: 'This is a very significant event in the development of 1Link. The solution has already found a high level of acceptance among major leasing companies and dealer groups, but Interleasing is the first to completely switch to vehicle e-procurement in this way.'
