A method for commercial brokers to measure placement share per client from the policy system: lines placed with the broker against lines the client holds, the renewal watch by producer, and the premium reconciliation that makes the book tie to the ledger.
A commercial broker retains most of its clients each year and still leaves money on the table with every one of them, because a client that places property and liability with the broker often places cyber, D&O and fleet with someone else. The policy system knows what was placed. This guide shows how to find what was not.
Per client:
Placement share = lines placed with the broker ÷ lines the client holds
Per producer:
Placement opportunity = Σ valued gaps across the producer's clients Renewal watch = renewals due in the window with no remarketing activity logged
The renewal watch is the retention half. Placement share is the growth half. Both come from the same export.
Client identifiers only. Names stay in the policy system.
The denominator has three sources and the report should say which applied.
A gap from the first two sources is a target. A gap from the third is a prospect. Both belong on the list, labelled.
written premium = Σ offices = Σ producers = Σ clients
The identity fails when a client sits under two producers after a book transfer, or when a mid-term adjustment was exported twice. Both are visible at exactly one level.
A manufacturing client, £40m revenue, five lines in the norm for that type.
| Line | Placed with us | Premium | Source | Gap value |
|---|---|---|---|---|
| Property | Yes | £62,000 | ||
| General liability | Yes | £18,000 | ||
| Motor fleet | No | Known, with another broker | £4,500 | |
| Cyber | No | Norm | £2,800 | |
| D&O | No | Lost at last renewal | £3,200 |
Placement share: two of five. Valued gap at the broker's commission rates: £10,500. The producer's list opens with the D&O line, because it was quoted and lost last year and the renewal is in eleven weeks.
For every policy expiring in the next ninety days, the report checks for a logged remarketing activity in the last sixty. None logged is the exception, ranked by premium. On a book of a few hundred clients this list is short and it is the retention plan for the quarter.
Lines named differently per system. A broker on two policy systems after an acquisition has "Fleet" and "Motor - Commercial" as separate lines. Map to one list before anything is computed.
Mid-term adjustments as new policies. An endorsement exported as a separate policy row doubles the line and the premium. The duplicate check catches identical client, line and inception; the reconciliation to written premium catches the rest.
Producer transfers. A book moved between producers mid-year appears under both. Decide the owner as of period end for the roll-up and keep the history as an attribute.
Carriers as clients. Some exports include carrier settlement rows alongside client policies. Filter by record type before the roll-up.
Mapped once, the export produces the same roll-up each quarter: placement share and valued gaps per client and producer, the renewal watch, and the premium reconciliation. Covirage builds it from the export as it is. The insurance brokers page describes the setup, and you can upload a sample policy export and see the roll-up in your browser.
Three ways, in order of certainty: the client told you at renewal, a placement you lost and recorded, or the norm for clients of that type and size in your own book. Record which one applies per line. A norm-based gap is a prospect; a known placement elsewhere is a target.
The lines your policy system uses: property, general liability, motor fleet, D&O, cyber, professional indemnity and so on. The set should be the one your producers quote, not a regulator's classification.
At your average commission on that line for clients of that size. State the basis. A list without values cannot be ranked.
