Acturis has landed the multi-million pound contract to provide the software for Marsh's recently launched Risk Trading Practice (RTP).
RTP is part of Marsh's UK retail business and arranges cover for small and medium-sized firms from 15 locations around the UK.
Acturis co-chief executive Theo Duchen said: "This is the biggest deal any software house has signed this year and probably the largest any will pick up for the foreseeable future. Marsh's RTP is probably a UK top five broker in its own right, so we're obviously delighted."
The deal is for three years and will allow Marsh brokers to trade electronically with the company's panel of 12 insurers.
Ron Hayes, executive director of RTP, said: "Acturis offered the strongest all-round proposition for our Risk Trading Practice."
He added: "We are committed to implementing a radical new business model using a paperless process, elimination of duplication through integration with insurer processes and electronic trading of commercial business. This transformation will eliminate the double-handling overhead, paper-based processes and re-work of the past, ensuring a much faster and efficient service for clients."
Broker Alexander Forbes also went live with the Acturis system for its insolvency schemes practice this week.
Duchen said: "We are leading the way in helping brokers to do commercial business electronically and that may go some way to explain our recent success."
