Wholesale distribution at a glance

Wholesale distribution is the business of buying goods from manufacturers in bulk and reselling them to other businesses: contractors, manufacturers, retailers, hospitals, restaurants and other distributors. It is a large, quiet part of the economy that runs on thin margins and a lot of inventory.

What a distributor does

A distributor sits between the companies that make things and the companies that use or resell them. The manufacturer wants to ship full truckloads to a few places. The customer wants a few cases, delivered tomorrow, on credit, with someone to call when something is wrong. The distributor closes that gap.

To close it, a distributor:

• Holds inventory close to customers so they do not have to.
• Breaks bulk, turning pallets into cases and cases into eaches.
• Extends credit, usually 30 days or more, to business buyers.
• Consolidates many suppliers into one order, one delivery and one invoice.
• Adds services such as kitting, cutting, light assembly, technical advice and vendor-managed inventory.

The official definition is close to this. The U.S. classification system describes wholesalers as selling goods, generally without transforming them, to business customers rather than the general public, usually from a warehouse or office with little or no display space (paraphrased from the NAICS and BLS descriptions linked below).

How the sector is organized

The North American Industry Classification System (NAICS) puts wholesale trade in sector 42 and splits it into three subsectors.

NAICS	Subsector	Who is in it	Takes title to goods?
423	Merchant wholesalers, durable goods	Distributors of things meant to last: auto parts, lumber, electrical supplies, hardware and plumbing, machinery, computers, metals	Yes
424	Merchant wholesalers, nondurable goods	Distributors of things used up quickly: groceries, drugs, paper, chemicals, petroleum, apparel, farm products, beverages	Yes
425	Wholesale trade agents and brokers, including electronic markets	Firms that arrange sales between buyers and sellers for a commission or fee	No

The line between 423 and 424 is about the goods. The line between merchant wholesalers and 425 is about the business model. A merchant wholesaler buys the goods, owns the inventory and carries the risk. An agent or broker never owns the goods. Most of what this section of the site covers (turns, fill rate, cash cycle, landed cost) applies to merchant wholesalers.

Manufacturers' sales branches

Census data separates independent merchant wholesalers from manufacturers' sales branches and offices, which are wholesale locations owned by the manufacturer itself. Several of the headline numbers below exclude those branches. When you compare figures, check which population each one covers.

How big it is

All figures below were retrieved on 2026-09-28. Each one names its source and period, because the different government programs count different things.

Employment and establishments

Measure	Figure	Source and period
Wholesale trade employees, all of sector 42	6,072,100	BLS Current Employment Statistics via Industries at a Glance, August 2026, seasonally adjusted, preliminary
of which 423 durable goods	3,418,600	Same, August 2026, preliminary
of which 424 nondurable goods	2,209,900	Same, August 2026, preliminary
of which 425 agents, brokers and electronic markets	443,600	Same, August 2026, preliminary
Private establishments, sector 42	628,831	BLS Quarterly Census of Employment and Wages (QCEW), 2025 annual average
of which 423	340,080	QCEW, 2025 annual average
of which 424	181,272	QCEW, 2025 annual average
of which 425	107,479	QCEW, 2025 annual average

An establishment in QCEW is a single physical location, not a company. A distributor with 12 branches counts 12 times, so the number of distributing companies is well below 628,831.

Sales and inventory

The Census Bureau's Monthly Wholesale Trade report for July 2026 (released 2026-09-10) put sales of merchant wholesalers, excluding manufacturers' sales branches and offices, at $801.3 billion for the month, seasonally adjusted. At that pace a year of sales comes to roughly $9.6 trillion (our arithmetic: 12 times the monthly figure). The same report put end-of-July inventories at $958.9 billion.

For a full year, the most recent annual benchmark is the Annual Wholesale Trade Survey for 2022, revised on 2026-08-31 to match the 2022 Economic Census:

2022 annual sales (AWTS, revised)	Amount
All merchant wholesalers, including manufacturers' sales branches	$11.08 trillion
Merchant wholesalers, excluding manufacturers' sales branches	$7.89 trillion
Manufacturers' sales branches and offices	$3.19 trillion

The Census Bureau has since folded the annual wholesale survey into its Annual Integrated Economic Survey, so later full-year figures will come from that program.

How distributors make money

A distributor's core income is the spread between what it pays for goods and what it sells them for. Everything else either widens that spread or protects it.

Source	What it is	Where it shows up
Gross margin on product	Selling price minus cost of the goods sold	The income statement, line by line on every invoice
Value-added services	Kitting, cutting, assembly, delivery, technical support, managed inventory, sometimes billed separately	Service revenue or a higher price on the product
Supplier rebates and allowances	Money back from suppliers for hitting volume targets, promoting a line or selling to specific customers	Usually a reduction to cost, often booked after the sale
Payment terms and discounts	Taking early-pay discounts from suppliers, or charging for credit	Cost of goods or financing income
Commissions	For agents and brokers only, a fee on sales they arrange	Commission revenue

The government numbers show how thin the result is. For 2022, the Annual Wholesale Trade Survey reports that merchant wholesalers excluding manufacturers' sales branches earned a gross margin of 20.3% of sales (27.2% for durable goods, 14.1% for nondurable goods) and spent 13.3% of sales on operating expenses. That leaves roughly seven cents on the dollar before interest, taxes and other items. Agents and brokers in the same survey earned commissions of 4.5% of the sales they arranged.

Those are sector averages across very different businesses. A grocery or pharmaceutical distributor lives on a few points of margin and enormous volume. An industrial or electrical distributor earns a wider margin on slower-moving, more technical products.

What makes the business hard

Thin margins leave little room for error

When the whole operation runs on a margin of about 20% and keeps about 7%, a small pricing mistake, an unbilled freight charge or a missed rebate claim can be a meaningful share of the profit on that customer. Price discipline matters more here than in most industries.

Cash is tied up in inventory and receivables

A distributor usually pays its suppliers before its customers pay it. In between, the money sits on the shelf as inventory and then in accounts receivable. The Census inventory-to-sales ratio for merchant wholesalers was 1.20 in July 2026, which means inventory on hand equaled about 1.2 months of sales. Growth makes this worse, because more sales mean more inventory and more receivables to fund before the cash comes back. We cover this in The cash conversion cycle.

SKU counts are large and demand is lumpy

A typical distributor carries thousands to hundreds of thousands of items, many of which sell a few times a year. Each needs a stocking decision, a reorder point, a price and a place in the warehouse. A small share of items produces most of the volume, and the long tail is where dead stock hides. See ABC analysis and cycle counting.

Prices move under you

Metals, lumber, fuel, chemicals and agricultural products can change price weekly. Supplier price increases arrive on their schedule, not yours, and customers often hold contract prices. A distributor that cannot see its true replacement cost and landed cost quickly will sell below cost without knowing it. See Landed cost and freight terms.

Customers expect it to be there

The whole point of a distributor is availability. Running out costs the order and, over time, the customer. Carrying too much ties up cash. Balancing the two is the daily job of purchasing, and the reason safety stock and reorder points and fill rate get so much attention.

Why the ERP sits at the center

In many industries the ERP is the accounting system with some operations attached. In distribution it is closer to the other way around. The decisions that make or lose money are made inside it, many times a day:

Area	What the ERP holds	Why it matters to profit
Inventory	Quantity on hand, on order and committed, by item and location; costing; units of measure	Availability, carrying cost and the accuracy of every margin number
Pricing	Price books, customer contracts, matrix and cost-plus pricing, rebates	The spread itself
Purchasing	Reorder points, suggested orders, supplier terms, receipts	How much cash goes onto the shelf, and when
Sales orders	Quotes, orders, allocation, backorders, shipping	Fill rate and customer experience
Accounts receivable	Credit limits, invoices, collections	How quickly cash comes back
Accounts payable	Supplier invoices, terms, discounts	How long you hold cash before paying

The metrics in this section, from inventory turns to the cash conversion cycle, all come out of this data. Whether you run Prophet 21 software, Epicor Kinetic or another system, the numbers are only as good as the item, cost and transaction records behind them.
