Wholesale-to-direct mapping — the commission step-up.

Wholesale-to-direct migration is the second synergy a carrier premium map reveals, and it's one of the cleanest — because converting a wholesale-placed policy to a direct appointment the buyer already holds lifts the commission on the same premium, same carrier, same client, with no new sale. The map finds the convertible premium by overlaying the target's wholesale placements against the buyer's direct appointments; the migration model turns that into a dollar figure.

§ 01 · The commission-lift ladderWhere the step-up comes from.

The commission-lift ladder shows where the step-up comes from. The biggest is wholesale to direct — a 300–500 basis-point lift, because a wholesaler captures a margin a direct appointment doesn't. Network or cluster to direct is 200–400 bps, and moving from one network to a better network is 50–150 bps. On top of the rate lift, converting off a network or cluster eliminates the access fee — 2%–4% of commission, sometimes higher on preferred markets. The underlying economics: wholesale pays a retail agency less than 60% of what a direct appointment on comparable business would, so the conversion recaptures the wholesaler's cut as the buyer's commission. A single $500K policy migrated at a 400 bps lift is $20K of incremental annual commission — roughly $140K of enterprise value at a 7× multiple, from one policy. The synergy-lens framework behind this is in market-access arbitrage.

§ 02 · The migration modelSizing the convertible premium.

The migration model is what turns the lift ladder into a defensible dollar figure, and it stacks four factors. Convertible premium — the wholesale-placed business on carriers the buyer holds directly. Rate differential — the lift from the ladder (say 4.0%). Migration percentage — the realistic share that actually converts, 70%–90%, accounting for underwriting fit and retention. And Year-1 renewal realization — roughly 50%, because conversions happen at each policy's renewal across the 12-month cycle, not on day one. The worked single-carrier model: $2M of wholesale premium × 4.0% × 80% × 50% = $32K of Year-1 lift, rising to $64K at full run-rate in Year 2, which is ~$448K of enterprise value at 7×. Post-rewrite retention runs 85%–95% (some accounts use the rewrite as an occasion to shop), which the model factors in. The pure-profit nature of this commission lift is in pure-profit contingency.

§ 03 · Wholesale share is hiddenThe four-step audit.

The convertible premium is the variable that decides the synergy size, and it's hidden — a seller rarely highlights how much of the book runs through wholesalers, because it's not a selling point. A buyer extracts it through a four-step pre-close audit. First, map the target's appointment footprint — which carriers it writes directly versus through wholesalers and networks. Second, overlay the buyer's direct appointments — because the arbitrage only works where the buyer can write directly what the target places wholesale. Third, segment by product line and class of business — because the conversion depends on the buyer's underwriting appetite fitting the business. Fourth, model on the actual renewal cadence — distributing the conversions across the renewal calendar rather than assuming instant migration. The audit is what produces the convertible-premium figure the migration model needs, and it's why wholesale-to-direct is a mapping exercise: the value lives in the overlap between the target's wholesale book and the buyer's direct appointments, which only a side-by-side map reveals.

§ 04 · Why it's a mapping synergyThe buyer-specific value.

Wholesale-to-direct migration is buyer-specific in the same way tier-jumping is: the synergy exists only for a buyer whose direct appointments overlap the target's wholesale book, so the same target is worth more to that buyer than to one without the appointments. That's why it belongs on the carrier premium map rather than in a generic synergy estimate — the map is the artifact that shows the overlap, segments it by line, and sizes the convertible premium. For a seller, surfacing the wholesale share proactively (a carrier-by-carrier breakdown of what's placed wholesale and could convert) earns higher offers from buyers who can capture it, the same way surfacing the tier-jump potential does. And the migration's durability is real — it doesn't depend on new sales or client behavior, only on administrative conversion at renewal — which is why it's one of the more reliable lines on the map. Built into the premium map alongside the tier-jump and the loss-ratio gate, wholesale-to-direct migration completes the picture of what a combined book is actually worth. How the appointments transfer to enable the conversion is in successor in interest.
