Accounting for commercial lines insurance brokerages

Commercial lines accounting is a trust problem. A meaningful share of the book is agency bill, which means the brokerage invoices the client, collects the full premium, holds it, and remits the net to the insurer after deducting its commission. That money is not the brokerage's. It sits in premium trust, and on a mid-sized book the balance can run well into seven figures.

Two things have to be right at all times: premiums payable to insurers, and the trust cash backing them. The premium trust reconciliation compares what is in the trust account against what is owed out of it, and a shortfall is a regulatory problem before it is an accounting one. Large single premiums, instalment plans, midterm endorsements, and cancellations all move that position between reconciliations.

Producer compensation is the second layer. Commercial producers usually work on splits — new business at one rate, renewals at another, sometimes with house accounts carved out. The brokerage recognizes the full commission as income and records the producer's share as expense or payable in the same period. When those splits live in a spreadsheet outside the ledger, the two stop agreeing, and year-end turns into a reconstruction.
