Commercial Lines Policy Admin Suite for MGAs

Commercial insurers and MGAs are increasingly acquiring or investing in innovative technologies — AI & predictive tools, process automation solutions, and specialized underwriting platforms, as highlighted by industry research from AM Best. 

Increased competition, embedded distribution, and E&S expansion are necessitating a faster response to market demands in 2026, especially in the SME risk marketplace, where precision and operational efficiency differentiate the insurance experience for agents and brokers. 

Lead authors of Conning’s 2024 Small Commercial Market Opportunities stated that small businesses, specifically, account for an estimated $140 billion in direct premium (with a 23% market growth from 2020 to 2024) and opportunity, with their unique risk management needs and volatility finding a large portion of this segment still uninsured and underserved. 

Recognizing the commercial markets’ needs and trends, Insillion tailors its MGA Policy Admin Systems to enable a frictionless insurance journey for every stakeholder involved. The core modules include:

Insillion’s Product Builder

The Product Builder enables an easy, UI-based product setup, made possible by Insillion’s Rater-to-API Excel solution. Instead of custom coding detailed policy journeys (a time and cost-intensive process), Insillion uses Excel, an application MGA underwriting and actuarial teams use every day, to convert existing rating models into high-performance, out-of-the-box-APIs.

How does Insillion’s Excel-to-API technology work?

Insillion automatically converts Excel-based rating logic into native JavaScript, which business analysts then configure and manage with low-code configurators. This: 

• Removes the need to run Excel in production, and
• Enables rapid implementation, sometimes within weeks.

Insillion also supports direct coding via plug-ins, giving MGAs the flexibility to choose the most efficient path without compromise. This allows MGA product teams to continue working in a familiar environment to make any premium logic or rating changes needed.

Insillion’s Product Builder also comes with: 

• Out-of-the-box APIs with Low-Code Document Generation 
• Version Control Testing 
• Bordereaux and Reporting 

Bordereaux & Reporting- MGA Software 

Insillion enables bordereaux reporting for the MGA’s capacity partners and any other authorized entities. Chosen data fields can be generated, viewed and shared as per the MGA’s discretion. Automated bordereau reporting by E-mail is also possible.

Rating Software for Commercial Lines 

An ideal Rating Engine is now more than just a back-office calculator — it is a strategic tool that provides a competitive edge in the market.  With its configurable, no-code interface, Insillion’s rating engine enables MGAs a speedy, efficient rate management system that bridges actuarial science with commercial reality. The Rate Modifier Functionality, in particular, greatly benefits commercial line MGAs by allowing easy, but tightly controlled deviation from standard rates. 

Insillion’s Approach to Rate Modification 

1. For the Whole Rating Table

Scope: Broad

Instead of defining adjustments for individual risk levels, underwriters can define a single discretionary range that applies to all risk parameters contained within a specific rating engine. 

Use Case: Ideal for portfolio-wide adjustments where the entire line or class of business requires a uniform margin of flexibility without granular tweaking. 

2. For Individual Risk Parameters

Scope: Targeted / Narrow

For granular control, underwriters can apply discretionary rating at specific levels, such as individual risk parameters or cover levels.

Use Case: Targeted loading or discounting on specific aspects of a risk, for eg: increasing the rate on the ‘Flood’ cover, while leaving the ‘Fire’ cover at base rate, without affecting the rest of the policy structure.

Insillion’s insurance rating systems also allow for flexible modification by value or percentage (defined relative to the base rate) as best suits the underwriting team’s needs.

Authorization & Defined Effective Timeframe 

The rate modifier can be configured to be used explicitly by the authorized underwriting groups, with a defined ‘effective period’ which ensures that discretionary ranges are reviewed periodically, preventing the persistence of outdated pricing strategies. 

Underwriting Workbenchfor Commercial Lines

Typically, MGAs distribute their commercial insurance products through brokers and agents, in many cases, competing to deliver their quote the quickest. With larger distribution partners who come with their own Agency Management Systems, MGAs need to be able quickly and seamlessly integrate with them to receive and respond to submissions easily. 

Insillion’s Underwriting Workbench enables commercial underwriters a speedy, structured underwriting lifecycle, starting with automated submission intake by Insillion’s Inflow. 

Intelligent Submissions Intake for Commercial Lines 

Inflow by Insillion extracts and validates risk information from any document format (ACORD, PDF, DOCX, etc.), through intake channels such as forms, email, messages, and broker portals against mandatory dropdown fields required for premium calculation. This: 

• Reduces manual rekeying, and 
• Ensures that client information aligns precisely with rating inputs before underwriting decisions are triggered. 

Submissions are also configured through rule-based pathways for Non-Straight Through Processing (NSTP) or referral flows. Pre-underwriting rules, such as submission blocking (preferred, referred, or declined risks) can be defined at intake, reducing hours spent on entry-level risk evaluation and simplifying data for human review. 

Granular Rating Capabilities for Commercial Lines 

The Workbench further supports granular underwriting actions, including the mapping of conditions, clauses, and warranties. These can be: 

• Automatically applied as mandatory requirements 
• Dynamically mapped based on selected coverages 
• Manually selected or deselected by underwriters where discretion is permitted 

All selections are reflected in policy documentation via automated document generation, as configured. 

3rd-Party Integrations & Enrichment 

Insillion also supports third-party risk integration with low IT lift via APIs, including data providers such as HazardHub, Veridion, and Elevon Data. External risk attributes are automatically fetched and mapped to underwriting fields, supporting policy review & decision-making. Actuarial inputs and updated pricing factors can similarly be maintained within master tables to ensure rating accuracy during premium calculation. 

Multi-Carrier Insurance Offerings 

MGAs that are starting out usually work with a single capacity provider on a straightforward product. As their business scales, however, MGAs may underwrite more complex products and feel the need to onboard more than one capacity provider. 

 A key strength of Insillion’s Underwriting Workbench is its multi-carrier capabilities. MGAs operating under delegated authority can manage: 

• LOB-level multi-carrier placement, where each line of business within a product can be presented to different capacity providers 
• Quote-level multi-carrier placement, where a single submission can be offered to multiple carriers for comparative terms and premium negotiation 

Role-Based Access Control (RBAC) ensures restricted data visibility when multiple carriers are involved, maintaining confidentiality and adherence to delegated carrier agreements.

Audit Trail & Premium Mapping 

Lastly, Insillion’s software ensures that every component of the computed premium is traceable, enabling audit trail and carrier transparency.
