Now live: P&C insurance accounting for MGAs and wholesalers, plus AAIS commercial lines platforms.
Excess insurance is rarely placed in isolation. It is layered, negotiated, and tied closely to underlying primary policies such as General Liability and Commercial Property. Many MGAs and wholesalers still rely on manual workflows, email negotiations, and disconnected carrier portals to place excess coverage.
Selectsys built a production-ready Excess Insurance rating platform that allows MGAs and wholesalers to rate, quote, bind, issue, and manage excess policies within a unified system. The platform is live today and designed to support layered structures, program business, and delegated authority workflows.
The Excess Insurance Rating Platform operates within the broader Selectsys Commercial & Specialty Rating Platform. This allows excess placement to be managed alongside primary lines such as General Liability, Commercial Property, and Workers Comp in a single operational environment.
See how MGAs and wholesalers scale this line using unified rating, binding, issuance, and accounting workflows.
For carriers that support API based workflows, Selectsys enables real time excess rating and quoting directly from the platform. Where supported, workflows extend from quote through bind and policy issuance.
New excess carrier API integrations can typically be delivered in approximately six weeks, assuming carrier access and documentation are available.
For excess programs that rely on ISO based rates, the platform supports standardized rating workflows while keeping submissions, underwriting, and placement centralized within a single system.
For delegated authority and specialty program business, Selectsys supports proprietary excess rating where rates and underwriting logic are owned by the MGA or carrier. This enables faster program launches and greater flexibility in structuring excess layers.
The Excess Insurance Rating Platform is integrated in production with multiple national and specialty carriers supporting excess and umbrella business.
