Businesses that provide wholesale services on a fee or contract basis act as intermediaries between manufacturers, importers or other suppliers and trade buyers. Rather than buying and reselling goods themselves, they typically arrange sales in return for a commission, brokerage fee or agreed contract payment. Their work can cover a range of products, including food and drink, clothing, household goods, machinery, building materials and industrial supplies. Typical services include finding suitable suppliers or customers, presenting product information, negotiating terms, processing or coordinating orders and helping to arrange delivery. Some businesses represent a supplier within a particular market, while others source goods for buyers or broker individual transactions. The goods are generally supplied directly by the seller to the buyer, although the intermediary may assist with paperwork, import or export arrangements and communication between the parties.
