# Wholesale distribution: how the industry works Canonical: https://industrywiki.org/industry/wholesale-distribution/ Published: 2026-10-26 Distributors bridge manufacturers and business buyers by holding inventory, extending credit and assembling reliable deliveries. Their value depends on availability and service relative to the capital and handling they consume. ## scope Merchant wholesalers that generally buy goods and resell them to businesses. Agents and brokers arrange sales without taking title and have different economics. The profile uses U.S. Census definitions and food distribution as one concrete example. ## classification ## segments ### name Broadline distribution ### description A wide assortment lets customers consolidate purchasing and deliveries. The distributor must manage many products with uneven demand. ### name Specialty distribution ### description Technical knowledge, regulated handling or a focused assortment supports a particular customer problem. ### name Drop shipping and agency ### description A merchant can own goods shipped directly by a supplier. An agent instead earns a fee for arranging a transaction; physical handling and title are separate questions. ## flow ### name Build the assortment ### description Buyers select suppliers, negotiate purchase terms and decide which products deserve inventory based on customer demand and replacement options. ### name Purchase and replenish ### description Forecasts become orders. Receiving and inventory records must distinguish available stock from committed, damaged or obsolete goods. ### name Sell and extend credit ### description Customers order against agreed prices, service levels and payment terms. Credit decisions expose the distributor to a separate risk from merchandise demand. ### name Assemble and deliver ### description Warehouses combine items into customer orders and delivery routes. Returns, substitutions and claims close the commercial loop. ## economics ### revenue Unit Products resold, sometimes supplemented by delivery charges, technical services or other agreed fees. ### payers Retailers, restaurants, contractors, institutions and other business buyers. ### costs #### name Merchandise #### explanation Purchase cost is reduced by applicable supplier arrangements and increased by losses, damage or obsolete stock; accounting depends on the agreement. #### name Fulfillment and service #### explanation Picking, transport, sales support and technical assistance depend on order complexity and customer behavior. #### name Credit and carrying cost #### explanation Financing inventory and receivables uses capital, while late payment and default can erase the profit on several successful orders. ### capital Warehouses, vehicles and handling systems support service, but inventory and receivables can also be substantial uses of funds. A business with modest fixed assets is not necessarily light on capital. ### working Capital Inventory plus customer receivables minus supplier payables is a useful simplified view of operating funds tied up. Faster growth can increase this need before it produces cash. ### mechanism The distributor earns a spread for making goods easier to buy and receive. Editorially, gross margin is only the starting point: an urgent small order with many lines and a distant delivery can cost more to serve than a large routine order. Product margin and customer contribution must therefore be examined together. ## operations ### activities - Manage assortment and supplier terms - Forecast replenishment and rotate stock - Price customer accounts and plan delivery routes ### assets - Inventory and warehouses - Delivery fleets or contracted transport - Supplier and customer account relationships ### roles - Category buyers - Sales and technical specialists - Warehouse, routing and credit teams ### records - Purchase orders and supplier agreements - Stock, expiry and customer order records - Invoices, credit limits and returns ### software - Enterprise resource planning - Warehouse and transport management - Customer pricing and credit control systems ### metrics #### name Inventory turns #### definition Cost of goods sold divided by average inventory valued on a compatible cost basis. #### why Connects merchandise throughput with funds tied up; sales-based ratios are not interchangeable. #### name Fill rate #### definition The share of ordered units or lines supplied as promised, with the chosen denominator disclosed. #### why Measures availability that customers are paying the distributor to provide. #### name Contribution after service #### definition Gross profit less the identifiable cost of handling, delivering and supporting an account. #### why Reveals customers whose apparent product margin disappears in expensive service. ## structure - A distributor compresses many supplier relationships into one purchasing interface. Customers benefit when assortment, availability and credit reduce their own procurement effort or stockholding. The distributor loses relevance when buyers can obtain the same reliability directly at lower total cost. - Local delivery density and product expertise can defend a business against larger rivals. Scale can improve purchasing, but carrying too many slow-moving products can dilute that advantage. Supplier exclusivity and customer concentration should be examined separately: a large sales book may still depend on one irreplaceable product line. ## risks ### risk Inventory obsolescence ### mechanism Products can expire, become technically outdated or lose demand before sale, turning recorded inventory into a loss. ### risk Credit losses ### mechanism Merchandise is delivered before payment; a customer failure leaves cash already spent on goods and delivery unrecovered. ### risk Direct-channel competition ### mechanism A supplier or platform may reach customers directly. The distributor must retain a service advantage beyond simply marking up a catalog. ## dependencies ### upstream #### slug food-processing #### label Food processing #### relationship Food distributors purchase packaged and prepared ingredients for business customers. #### slug trucking #### label Trucking #### relationship Carriers move goods from suppliers and between distribution points. ### downstream #### slug restaurants #### label Restaurants #### relationship Foodservice operators buy mixed ingredient and supply orders. #### slug grocery-retail #### label Grocery retail #### relationship Retailers use distributors for assortment, availability and replenishment. ### substitutes #### label Direct manufacturer purchasing #### relationship Can replace the intermediary when customers can absorb supplier minimums, lead times and purchasing complexity. ## worked Example ### title Growth consumes cash before it releases it ### assumptions - Illustrative distributor holds $300,000 of inventory and $200,000 of receivables, with $180,000 of supplier payables. - Average credit sales are $2,000 per day; other balances remain unchanged. ### calculation - Simplified operating working capital = $300,000 + $200,000 − $180,000 = $320,000. - Collecting customer invoices ten days sooner releases 10 × $2,000 = $20,000. - Working capital falls to $300,000 without any change in product gross margin. ### takeaway Payment discipline can free cash independently of sales growth. The calculation excludes cash balances, taxes, seasonality and disputed or uncollectible invoices. ## scenario ### change A customer requests daily delivery instead of twice weekly. ### effects - Average order size falls and stop frequency increases. - Handling and delivery costs rise even if weekly merchandise volume is unchanged. - The distributor must improve route density, revise the service agreement or accept lower contribution. ### watch - Gross profit per delivery - Order lines per stop - Customer payment days ## misconceptions ### claim A distributor only adds a markup. ### correction Inventory availability, credit, order consolidation and delivery can replace real costs the customer would otherwise incur. ## sources ### id census-wholesale ### title Monthly Wholesale Trade - Definitions ### organization U.S. Census Bureau ### url https://www.census.gov/wholesale/definitions.html ### supports Merchant wholesalers, agents, brokers, title to goods and wholesale inventory definitions. ### id usda-wholesale ### title Retailing & Wholesaling - Wholesaling ### organization USDA Economic Research Service ### url https://www.ers.usda.gov/topics/food-markets-prices/retailing-wholesaling/wholesaling ### supports Food wholesaling functions and intermediary types; a sector example rather than all wholesale markets. ### id sysco-2025 ### title Sysco Corporation 2025 Form 10-K ### organization Sysco Corporation ### url https://www.sec.gov/Archives/edgar/data/96021/000009602125000099/syy-20250628.htm ### supports Company example of foodservice customers, purchasing, warehousing, delivery and business risks. ## evidence ### scope - census-wholesale ### flow - usda-wholesale - sysco-2025 ### economics - census-wholesale - sysco-2025 ### operations - sysco-2025 ### structure - usda-wholesale ### risks - sysco-2025 ## related Concepts - working-capital - inventory-turns - economies-of-scale ## editorial Note Economic reasoning and the hypothetical calculation are editorial synthesis.
