Which channels produced closed commissions?

A brokerage might close forty deals in a year. At that volume a single misattributed transaction distorts the whole ranking, which is precisely why lead counts are useless here.

Matching on the counterparty and ranking on commission earned means the report describes the deals that happened rather than the interest that did not.

Brokers reasonably say the business is relationship-driven, and then spend meaningfully on listing platforms and campaigns without ever testing which relationships those produced.

Putting outbound lists, platforms and campaigns on the same commission axis does not dispute that relationships close deals. It shows which spend puts brokers in front of the right people.

A commercial closing statement names an entity. A single purpose vehicle, a partnership, a fund, a numbered company formed for the transaction six weeks before it completed. That name appears nowhere in the inquiry history, because the person who first rang about the building was an acquisitions director, an asset manager, a family office adviser or a principal using a personal address, and the vehicle did not exist at the time. Any attempt to join the two lists on the entity name returns almost nothing, which is why brokers who have tried this in a spreadsheet concluded it could not be done.

Matching on the individual's direct dial and work email solves it, because those details persist across every deal that person will ever do. They appear on the original inquiry, on the confidentiality agreement, on the deal file and in the broker's own contact record, and they stay stable for years even as the entities around them are formed, funded and dissolved from one transaction to the next. A person changes employer perhaps every few years; a vehicle changes every deal, which is why one of them makes a usable key and the other does not.

That also means the matching improves as a relationship ages rather than decaying the way a tracking cookie does. A principal who bought through one vehicle in a previous year and another this year is the same person to the report, so a campaign that first reached them three transactions ago keeps earning credit for the business it started rather than losing it to whichever listing platform happened to carry the most recent instruction. In a market where the same few dozen buyers transact repeatedly, that distinction accounts for most of the difference between the two answers.

Commercial listing platforms are purchased as annual subscriptions, packages of featured slots, or promotions bought per instruction, and the invoices are substantial enough to reach the partners' agenda every year without fail. The reporting that arrives alongside them counts views, saved searches and inquiry forms, all of which are real activity and none of which is a commission. Renewal conversations therefore run on volume of interest, which a platform is uniquely well placed to generate and uniquely poorly placed to convert into anything the brokerage can bank.

The brokerage holds the other half of the answer and has done all along. Every closed deal has a counterparty with a name and a contact detail, and that counterparty either appears in the platform's inquiry export for the relevant instruction or does not. Running that comparison across a year of closings is a short exercise using two files the firm already possesses, and it answers the renewal question directly rather than by inference. No negotiation with the platform is required to obtain the inquiry list, because it was supplied as part of the service being paid for.

It cuts both ways, which is what makes it worth doing rather than merely satisfying. Platforms sometimes produce far fewer actual buyers than their inquiry counts imply, and sometimes produce the two transactions that carried the year while looking unremarkable on every metric they themselves report. Either finding is considerably more useful at the negotiating table than an opinion about whether the subscription feels expensive this year, and either one can be shown deal by deal rather than asserted as a total.

A commercial commission is rarely kept whole. It is split with a co-operating brokerage on the other side, shared with an introducing office in another market, divided between the producing broker and the firm under a schedule that moves as the broker crosses thresholds, and reduced again by a referral fee to whoever brought the instruction in. By the time the money settles, the firm may retain a modest fraction of the headline figure printed on the closing statement, and that fraction varies deal by deal rather than holding steady across the book.

Ranking channels on gross commission therefore ranks them on transaction size, which is an artefact of the asset class and the market rather than a statement about what the marketing produced. A campaign generating large co-brokered deals can look dominant in the table while contributing less to the firm than a quieter source producing smaller transactions the firm keeps in full. Nothing on a gross ranking reveals that, because the column that would reveal it is the one the firm chose not to export when it built the file.

Whichever figure the firm manages itself on is the one to export, and consistency matters more than which choice is made. The report ranks on the column it is given, so a brokerage that reports internally on retained fee receives a channel ranking that reconciles to its own profit and loss rather than to a press release about deal volume. That reconciliation is what makes the number usable in a partners' meeting, where the first question asked of any marketing figure is whether it ties to the accounts.
