Insurance brokers that use the Sirius system will soon have direct access to AXA's commercial quotations and product information.
The two companies have agreed to link Sirius for Broking with AXA's e-commerce portal, business-risk.com. The launch is scheduled for September.
The move is intended to streamline the process for commercial lines business placement by eliminating the need to re-key data. Information and quotation data will pass directly from AXA into the Sirius back-office system.
AXA commercial and intermediary lines director Mark Cliff said: "Sirius has a customer profile that closely matches our target broker.
"To be able to interact electronically with the Sirius broker population will be a real plus for all parties."
Initial work is being carried out on policies for commercial contractors, flats, property owners and small combined business.
The tie-up is the first of several for AXA. In early May, it said it was negotiating with four software houses to integrate their brokers' back-office systems with business-risk.com.
A deal with Acturis is also believed to be in the pipeline.
Sirius also plans to provide access to other insurers' e-commerce platforms.
Insurance division managing director Mike Dodd said: "This development paves the way for us to work with other insurer extranets and electronic channels."
He added that Sirius was in talks with most of the large insurers and predicted that the company would have a deal in place with another major insurer "in a matter of weeks".
If Sirius were to provide a single point of entry into a number of insurer extranets, it could mean the start of competition for the new Polaris initiative, E-Market.
E-Market's is still under development, but is on track to go live with phase one early next year.
Initially it will be a portal that provides a single sign-on for the extranets of its large insurer investors.
