Wholesale Trade Agents and Brokers (U.S.) — NAICS 425120

An investor's primer. Figures are U.S. federal statistics unless noted. "Agents and brokers" here means the commission middlemen of the goods economy — not stockbrokers or real-estate agents.

1. Overview

Wholesale trade agents and brokers are the intermediaries who arrange the sale of goods without ever owning them. A manufacturers' representative who sells a factory's products to distributors, an online marketplace that matches used-car dealers, a food broker who gets a snack brand onto grocery shelves, a hospital group-purchasing organization that negotiates supply contracts — all earn a commission or fee on transactions they facilitate, and all sit in this industry (North American Industry Classification System, or NAICS, code 425120).[1][2]

Census treats these businesses as wholesalers even though they neither manufacture goods nor own wholesale inventory. That is deliberate: the classification follows their role in arranging the wholesale distribution of goods.[3] It also means that "manufacturers' representative," "electronic marketplace" and "wholesale auction" can all sit in the same six-digit industry despite having very different operations.

Why an investor cares: this is the "toll booth" layer of business-to-business (B2B) commerce. Owners don't carry inventory, so the model is capital-light and high-margin on incremental volume — but revenue is a thin slice of the goods that flow through, and the whole layer is exposed to being cut out (disintermediated) when buyers and sellers connect directly. The economics reward intermediaries that add something hard to replicate — data, financing, logistics, retail relationships — and punish pure "order-passers."

  • Public-market route: a handful of scaled, mostly digital, marketplaces and outsourced sales agencies — auto-auction platforms, a manufacturing marketplace, a consumer-goods agency (tickers in §4 and §10). Note that some platforms record revenue as principals, not agents, despite calling themselves marketplaces.
  • Private route: the giant of the sector (Cox Automotive's Manheim) is privately held, the large healthcare purchasing groups are member-owned or recently taken private, and the long tail is tens of thousands of small independent rep agencies — an area for private-equity roll-ups and owner-operators rather than public shareholders.

2. What it is and how it's structured

The U.S. wholesale sector splits into two economic models. Merchant wholesalers take title — they buy goods, own the inventory, mark them up and resell (durable goods sit in NAICS 423; nondurable goods in NAICS 424). Agents and brokers (NAICS 425) do not take title — they never own the goods, carry no inventory, and are paid a fee for arranging the deal.[4][2] That single distinction — ownership vs. no ownership — is the whole industry's defining feature and drives its economics.

What 425120 includes:[1][2]

  • Independent and manufacturers' sales representatives — the largest population by headcount; independent contractors who sell a factory's line to wholesalers, retailers, or industrial buyers, usually carrying several non-competing lines.
  • Business-to-business electronic markets — online marketplaces for durable and nondurable goods.
  • Auction companies and automobile auction agents/brokers.
  • Group purchasing organizations (GPOs) acting as agents to negotiate supply contracts.
  • Commission merchants and import/export agents and brokers.

A traditional representative receives a territory or account mandate from a manufacturer, prospects and services customers, negotiates or solicits orders, and passes accepted orders to the principal or a distributor for fulfillment. Agencies often represent several complementary, noncompeting lines, spreading the cost of customer relationships across multiple principals. Compensation is generally a percentage of sales, although retainers, market-development fees and service fees are used when a new line requires substantial "missionary" work before producing orders.[5][6]

A NAICS 2022 change matters for anyone comparing older data: the former six-digit industry 425110 ("Business to Business Electronic Markets") was folded into 425120; Census concluded that Internet delivery had become a generic business method rather than a distinct production function. Historical series spanning that change should be treated cautiously.[7][1]

What it excludes (adjacent codes): merchant wholesalers who own inventory (423/424); retailers (44–45); securities and commodity brokers (523) and insurance agents (524) — those trade financial products, not goods; real-estate agents (531); and freight/customs brokers who arrange transportation rather than the sale of goods (freight transportation arrangement, 488510). "Business brokers" who sell whole companies are a services activity, not this code.

Ownership mix: a barbell. A small number of large corporations — digital marketplaces, national outsourced-sales agencies, and big purchasing organizations — sit atop a very long tail of tiny, often one-person independent rep firms.

3. How big it is

U.S. federal statistics for NAICS 425120 (employer businesses):

Metric Value Source
Establishments 34,962 Census County Business Patterns, 2023[8]
Paid employees 243,788 Census County Business Patterns, 2023[8]
Annual payroll $17.5 billion Census County Business Patterns, 2023[8]
Firms 32,160 2022 Economic Census[8]
Receipts ~$786 billion 2022 Economic Census[8]
Sales (2023 AIES) $856.4 billion Census Annual Integrated Economic Survey, 2023[9]
SBA small-business size standard 125 employees SBA, 2023[8]

BLS estimated 502,330 wage-and-salary jobs in May 2023, with a $30.60 median hourly wage; nontechnical wholesale sales representatives accounted for 130,340 of those jobs and averaged $91,220 annually. OEWS excludes self-employed workers and is not directly comparable with Census establishment counts.[10][11]

Read the "$786–856 billion" carefully — this is the single most important caveat. For agents and brokers, the Census has firms report two different numbers: the gross value of the goods they arrange the sale of (large) and the commissions and fees they actually keep (a fraction of it).[3] Census instructs an agent to report the gross selling value of goods sold for others separately from its commissions: its example converts $200,000 of commissions earned at a 5% rate into $4 million of gross selling value.[3] Accordingly, the receipts figures above are principally facilitated merchandise value — analogous to GMV — not broker turnover, gross profit or value added. The sanity check: $786 billion of "receipts" against only $17.5 billion of payroll and ~244,000 workers would be impossible if it were fee income — it implies the reported total is transaction value, and the real revenue pool (commissions) is far smaller, on the order of a few percent to low-teens percent of that value. Our federal ground-truth data does not include a separate national commission total, so this primer does not state one.

The undercount. County Business Patterns counts only employers. This industry is unusually full of nonemployer sole proprietors — independent reps working alone with no payroll. Private research house IBISWorld counts roughly 103,000 businesses in the industry (2024), versus the ~35,000 employer establishments above; the gap is tens of thousands of one-person rep shops the employer statistics miss.[12] A federal regulatory analysis using Census SUSB data states that approximately 99% of wholesale-agent and broker firms employ fewer than 125 people.[13] So the federal establishment and employment figures understate the true operator base — read them as the employer core of a much more fragmented cottage industry.

Employment history caveat. Even employment history is unusually classification-sensitive. A BLS recoding exercise associated with its 2018 benchmark moved about 336,000 jobs previously classified as wholesale trade agents and brokers into wholesale, retail, transportation and professional-services series — a warning against reading long-run employment charts as organic business growth or contraction.[14]

Concentration is low overall. The largest four firms earned 25.4% of receipts; the top eight, 31.0%; the top 20, 38.6%; the top 50, 44.8% (2022 Economic Census). The Herfindahl-Hirschman Index (a standard concentration measure) is suppressed in our data.[8] These economy-wide numbers mask the real story: specific sub-markets are far more concentrated (auto auctions and healthcare GPOs are near-oligopolies), while the manufacturers'-rep world is atomized.

4. The investable universe

There are only a handful of pure public plays, most of them digital marketplaces or outsourced-sales agencies. Note that the big auction names' formal industry codes vary, but their fee/consignment economics are the agent-broker archetype (auction companies are explicitly named in 425120).[1] Critically, investors must separate commission or service revenue from inventory sales, and evaluate GMV, take rate, client retention, service attachment and credit or guarantee exposure rather than relying on consolidated revenue alone.

Public companies (scale = most recent reported annual figures):

Company Ticker What it does (agent/broker model) Scale
OPENLANE KAR (NYSE) Digital wholesale used-vehicle marketplace + dealer floorplan financing 2024 revenue $1.79B; 1.4M vehicles; ~$27B gross merchandise value (GMV)[15]
Copart CPRT (Nasdaq) Online salvage & used-vehicle auctions (consignment) FY2024 revenue $4.2B; net income $1.4B[16]
RB Global RBA (NYSE) Commercial-asset & salvage-vehicle auction marketplaces (Ritchie Bros. + IAA) 2025: $16.2B gross transaction value; $3.5B service revenue; $1.1B inventory sales revenue[17]
Advantage Solutions ADV (Nasdaq) Outsourced sales, retail merchandising & consumer-goods (CPG) brokerage 2025 revenue $3.54B; adjusted EBITDA $332M[18]
ACV Auctions ACVA (Nasdaq) Online dealer-to-dealer wholesale vehicle auctions 2025: 829,276 marketplace units; $348M auction-marketplace revenue; $296M other marketplace revenue[19]
Liquidity Services LQDT (Nasdaq) Surplus-asset auctions and B2B marketplaces (consignment + purchase model) FY2025: consignment 81.3% of GMV (29.0% of revenue); purchase model 18.7% of GMV (65.1% of revenue)[20]
Xometry XMTR (Nasdaq) B2B marketplace for custom manufacturing 2024 revenue $545M ($486M marketplace)[21] — Note: Xometry records marketplace sales gross as principal, not agent[22]

(CPG = consumer packaged goods; EBITDA = earnings before interest, taxes, depreciation and amortization; GMV = gross merchandise value.)

Note on Xometry: Despite calling itself a marketplace, Xometry's 10-K concludes it is the principal in parts and assembly sales because it controls fulfillment, so it records marketplace sales gross rather than net of supplier costs. This makes it an imperfect comparable for pure agent economics.[22]

Note on Liquidity Services: This is a useful demonstration of why nominal revenue and gross margin cannot be compared without first separating agent from principal transactions: consignment (agent) transactions represented 81.3% of GMV but only 29.0% of revenue because only the fee is recognized, while purchase-model (principal) transactions were 18.7% of GMV but generated 65.1% of revenue because the full resale value is booked.[20]

Major private and member-owned players:

  • Cox Automotive / Manheim — the world's largest wholesale used-vehicle auction: ~8 million vehicles a year, ~$57 billion of value, ~$3 billion of revenue; part of privately held Cox Enterprises.[23] Manheim and OPENLANE are the two anchors of U.S. wholesale auto remarketing, with ACV and Copart the fast-growing digital challengers.
  • Acosta Group — a leading CPG sales-and-marketing agency; expanded after acquiring CROSSMARK and Product Connections (2024). CROSSMARK alone employs more than 25,000 people; Acosta's ADW unit focused on Costco reports more than 200 broker specialists in 11 global offices.[24][25][26]
  • Premier — formerly a public healthcare GPO (Nasdaq: PINC), Premier was taken private by Patient Square Capital in November 2025 in a $2.6 billion transaction and is therefore now private-market exposure.[27][28]
  • Vizient and HealthTrust — large, member-owned healthcare GPOs.
  • ~100,000 independent manufacturers'-rep agencies — mostly nonemployer or very small firms, connected through bodies like the Manufacturers' Agents National Association (MANA, founded 1947).[5][12]

Takeaway: the public options are concentrated in vehicle remarketing plus a few one-off franchises (a manufacturing marketplace, a consumer-goods agency, a surplus-asset platform). The broad "manufacturers' rep" economy is essentially not publicly investable except through the manufacturers whose goods they carry.

5. How the money works

Owners make money on the spread between fee income and a light cost base — mostly people, technology and, for marketplaces, a bit of working capital. There is no inventory to finance or write down. A true agent avoids merchandise purchases, inventory financing, warehousing, shrinkage and obsolescence. Its principal costs are sales compensation, account-management and support labor, travel, trade shows, CRM and data tools, marketing, insurance, legal costs and management overhead. This makes working-capital requirements low but human-capital intensity high. The metrics that matter:

  • Take rate (fee as a % of transaction value). This is the master gauge. For online vehicle marketplaces it runs in the mid-to-high single digits of GMV. For GPOs, administrative fees are typically 1.5%–3% of member purchasing (a cap that is also a regulatory line — see §7).[29] For manufacturers' reps, commissions commonly run 5%–15% of the net invoiced sales they generate for their principals. MANA's survey of members found common commission ranges of 5–7% for sales to OEMs (averaging 6%), 5–9% for distributors (averaging 7%), and 7–14% for end users (averaging 11%); however, the underlying surveys were conducted in 1999–2005 and should be treated as a directional range, not a current market tariff.[30][31]
  • Gross merchandise value / volume. Because revenue = volume × take rate, GMV and unit counts (vehicles sold, purchasing dollars run through contracts) are the top-line drivers investors watch.
  • Contribution margin per transaction and operating leverage. Marketplaces have high fixed costs (platform, sales force) and low marginal cost per deal, so profitability swings hard with volume. Traditional rep agencies are closer to a billable-people model — economics track headcount productivity and the value of the lines they carry. A percentage commission provides high incremental contribution once an account and territory are covered, but revenue can fall immediately when the underlying principal's orders decline.
  • Attach and adjacencies. The durable franchises layer higher-margin services onto the core match: OPENLANE bundles dealer floorplan financing; auction platforms sell inspection, transport and title services; GPOs and agencies sell data and analytics. These deepen the take rate and raise switching costs.
  • Working capital / float. Some models briefly touch the cash (financing arms, inventory-sale lines), but the core agent model is asset-light; return on capital is high when volume holds.

The core risk baked into every one of these lines: it is a thin, pass-through economics business. A few points of take rate on someone else's goods is a good living until a principal, a buyer, or a platform decides the middleman is optional.

6. What drives demand

  • The volume of goods that needs selling. Reps' commissions ride on their principals' sales, so industrial production, manufacturing output and B2B goods demand set the ceiling. When factories ship more, reps earn more.
  • The outsourcing calculus. Manufacturers use independent reps precisely because a commission-only, variable-cost sales force is cheaper and reaches fragmented buyers better than a fixed in-house team.[32][33] When companies cut fixed costs or enter new territories, rep demand rises. This is especially attractive for smaller or foreign manufacturers entering a new territory.
  • Used-vehicle supply (off-lease returns, dealer trade-ins, new-car availability, accident/salvage volumes) drives the auto-auction platforms — the most investable slice.
  • Healthcare spending and hospital purchasing drive GPO fee income.
  • Retail and CPG promotional activity — new-product launches, in-store merchandising, retail-media budgets — drive the sales-and-marketing agencies.
  • Retail and customer consolidation cuts both ways. Large accounts increasingly demand sophisticated category analytics, national coverage, electronic data integration and in-store execution, favoring scaled agencies. But fewer, larger buyers also gain negotiating power and can concentrate an agency's revenue.
  • Digitization cuts both ways: it grows online B2B marketplaces (double-digit growth at ACV, OPENLANE's marketplace segment, Xometry)[19][15][21] while threatening traditional reps whose match-making can be done by software. B2B marketplaces reduce search and transaction costs, improve price discovery and create network effects. At the same time, manufacturers can use direct e-commerce, CRM automation, retailer procurement systems and AI-assisted lead generation to bypass traditional representatives.

7. Regulation

The sector is lightly regulated as a whole — there is no single federal overseer of "agents and brokers," and most relationships are governed by ordinary contract and commercial law. The pockets that do face rules:

  • GPOs and the Anti-Kickback Statute. Healthcare purchasing organizations are paid by the vendors whose products they get onto hospital shelves — an arrangement that would otherwise look like an illegal kickback under the Social Security Act. A 1986 statutory safe harbor permits it if fees are disclosed and generally 3% or less of purchase price. HHS OIG explains that the GPO safe harbor protects vendor administrative fees only when its definition and disclosure conditions are met; a written customer agreement must specify the vendor fee, or its maximum, if it is not fixed at 3% or less.[29][34] The vendor-funded model draws periodic Congressional and GAO scrutiny over whether it truly lowers costs.[29]
  • State sales-representative statutes. Most states have laws requiring principals to pay independent reps their earned commissions promptly, often with penalties (up to treble damages) for wrongful nonpayment — the main legal protection for the rep population.
  • Auto auctions: state motor-vehicle-dealer licensing, title and salvage-title rules, and federal odometer-disclosure law (Truth in Mileage Act).
  • Agricultural products: USDA requires a produce broker negotiating for another person generally to obtain a PACA license from the first transaction.[35] Livestock dealers and market agencies buying on commission must register under the Packers and Stockyards Act and maintain a bond or equivalent.[36]
  • Worker classification: IRS analysis of independent-contractor vs. employee status turns on behavioral control, financial control and the nature of the relationship; misclassification can create employment-tax and benefit liabilities.[37][38]
  • Antitrust: relevant where B2B marketplaces or GPOs gain enough share to raise foreclosure or fee-setting concerns.

8. Competitive dynamics and consolidation

Two competitive worlds coexist. At the top, scaled digital platforms and national agencies compete on network density, data and bundled services, and are consolidating: Ritchie Bros. bought IAA to form RB Global (2023); Acosta absorbed CROSSMARK and Product Connections (2024); OPENLANE (formerly KAR) sold its U.S. physical ADESA auctions to Carvana (2023) to go digital-first; Advantage Solutions has been divesting to simplify; Patient Square Capital took Premier private (2025).[17][24][15][27] In vehicle remarketing, Manheim and OPENLANE anchor a market that ACV and Copart are attacking digitally; in healthcare, a few GPOs (Vizient, Premier, HealthTrust) dominate.

At the bottom, the manufacturers'-rep world stays atomized — low barriers to entry (a phone, relationships and product lines), high barriers to scale. This is where private-equity roll-ups and owner-operators play. The structural pressure across both worlds is digitization: platforms that pool liquidity and data compress the economics of, and can outright replace, the individual middleman.

9. Risks

  • Disintermediation. The existential risk. Principals sell direct, buyers buy direct, or an e-commerce platform replaces the human match.
  • Automation and AI. Software and AI erode the value of human match-making. The Bureau of Labor Statistics (BLS) projects wholesale and manufacturing sales-rep employment growing only ~1% over 2024–2034 — below average — citing e-commerce and AI as demand limiters.[39][32]
  • Cyclicality. Fee income tracks goods volumes, used-vehicle prices and industrial output, all cyclical. Industrial-equipment, machinery and construction-product representatives follow capital spending, manufacturing and building cycles. Consumer-staples brokerage is steadier, while discretionary consumer goods follow retail demand and inventories.
  • Take-rate and commission compression. Thin pass-through margins invite fee pressure from both sides of the trade and from competing platforms.
  • Concentration risk (for reps). A small agency that loses a key principal line can lose much of its income overnight. Losing one important line can remove both current income and the reason customers take the agency's calls.
  • Contractual risk. A principal can terminate an agency, take a major account in-house, redefine a territory, classify an account as a noncommissionable "house account," change the commission base or appoint a competing channel. State laws may protect post-termination commissions or impose damages, but rules vary.
  • Key-person risk. Founder and key-salesperson relationships may not transfer cleanly after an acquisition, making succession and retention critical.
  • Worker-classification risk. Misclassification of independent contractors can create employment-tax and benefit liabilities.[37][38]
  • Regulatory. The GPO vendor-fee model, in particular, could be curbed if the safe harbor is narrowed.[29] Agricultural brokers face PACA and Packers and Stockyards Act requirements.[35][36]

10. How to invest, and the outlook

Public routes. The cleanest exposure is vehicle remarketing — OPENLANE (KAR), ACV Auctions (ACVA), Copart (CPRT) and RB Global (RBA) — a structurally growing shift of a physical auction business onto digital rails. Beyond autos, exposure is idiosyncratic: Advantage Solutions (ADV) for consumer-goods brokerage, Liquidity Services (LQDT) for surplus-asset marketplaces. Xometry (XMTR), despite calling itself a marketplace, records sales gross as principal and is an imperfect agent comparable.[22] (Tickers, valuations and dividends should be assessed on each company's own merits; several of these trade more like software/marketplace growth names than like "wholesale" stocks.)

Private routes. The sector's largest asset — Manheim — is inside privately held Cox Enterprises and not directly investable.[23] Premier, formerly public, is now private following its 2025 acquisition.[27] The realistic private plays are (a) roll-ups of independent rep agencies and specialty brokers, where fragmentation creates buy-and-build opportunities, and (b) member-owned or PE-backed purchasing and agency platforms. Owner-operators can enter the rep business cheaply, which is both the opportunity and the reason margins stay competitive.

Private-market underwriting. Attractive targets have long-tenured principal relationships, repeat accounts, low customer churn, multiple complementary lines and a sales organization that is not entirely dependent on the founder. Underwriting should normalize actual commissions and fees — not facilitated merchandise value — and map revenue by principal, customer, product line and salesperson. Representative agreements should be tested for termination, assignability, territory exclusivity, change-of-control, house-account and post-termination commission provisions. The investor should also distinguish recurring account maintenance from founder-driven origination, confirm contractor classification and assess whether acquired relationships genuinely survive a change in ownership.

Near-term drivers to watch (forward-looking): the pace of the physical-to-digital shift in wholesale auctions; used-vehicle supply normalizing as leasing recovers; whether AI tools displace order-taking reps or augment the higher-value ones; retail-media and CPG promotional budgets for the agencies; and any move to tighten GPO fee rules. The through-line for the next several years: intermediaries that own data, liquidity, financing or logistics should compound; those that only pass orders along face slow erosion. Overall industry "size" (~$775 billion of goods value in 2024 by IBISWorld's estimate) has been roughly flat[12] — this is a share-shift and margin-quality story, not a rising-tide one.
