Custom Insurance Brokerage, Underwriting & Policy Administration Portals: Automating Quotes, Claims, and Commission Splits

Why Insurance Brokers and MGAs Lose Deals to Slow Manual Quoting

In motor, medical, marine cargo, domestic package, and corporate asset insurance, speed and accuracy win the client. Yet in most insurance brokerages, Managing General Agents (MGAs), and Bancassurance departments, generating a comparative quote across five underwriters still requires an account executive to open five different Excel rate cards, calculate levies (Training Levy, Policyholders Compensation Fund, Stamp Duty) by hand, type a Word quotation, and email it 24 hours later. Once the client pays via M-Pesa or bank transfer, operations staff manually re-key the data to issue a cover note, chase the lead underwriter for policy numbers, and spend days at month-end reconciling sub-agent commission clawbacks and insurer bordereaux spreadsheets.

Off-the-shelf Western agency management software rarely handles local multi-tier regulatory levies, mobile-money premium financing (IPF), or instantaneous integration with local motor/digital certificate registries. At devManue Insurance & Fintech Engineering, we build custom Policy Administration Systems (PAS), Multi-Insurer Aggregator Portals, and Claims Management Workflows tailored to your exact underwriting binders and brokerage operations.

1. Core Insurance Brokerage & Policy Administration Modules & Build Costs

We architect your insurance platform around four auditable modules that take a prospect from a 30-second self-service quote to instant digital policy issuance and automated commission settlement:

2. Deterministic Multi-Underwriter Rating & Statutory Levy Calculation in Python

Insurance rating rules are notoriously nuanced: a comprehensive commercial motor policy might apply a base rate of 4.25% of sum insured, subject to a minimum basic premium of KES 37,500, plus a 0.25% windscreen extension above KES 50,000, a Political Violence & Terrorism (PVT) rider, a 10% no-claim discount, followed by statutory Training Levy (0.20%), Policyholders Compensation Fund (0.25%), and fixed Stamp Duty (KES 40). Hardcoding these formulas in frontend JavaScript or fragile spreadsheets leads to under-quoted policies that the brokerage has to subsidize out of its own commission.

We implement a rule-driven PostgreSQL & Python Rating Engine that evaluates every active underwriter binder in parallel and returns auditable, cent-accurate premium breakdowns in under 25 milliseconds:

3. Boosting Policy Renewal Retention from 62% to 88%+ with Automated Workflows

In general insurance, acquiring a new policyholder costs 5x more than retaining an existing one—yet brokerages lose 30%+ of renewals simply because the renewal notice arrived late or required the client to fill out paper forms again. Our platform runs a daily Celery renewal scheduler that automatically recalculates the vehicle or asset's depreciated sum insured at 60, 30, 14, and 3 days prior to expiry, dispatches a personalized WhatsApp and email renewal quote with a one-click M-Pesa STK Push / Card payment link, and issues the renewed policy certificate within 10 seconds of payment confirmation.
