Factories can have a few small machines or many large machines, or any combination of machines. Contract embroidery is a term used to describe embroidery being done on goods that are supplied by the customer to the embroidery house. Contract embroidery is limited to the trade. A company offering "Contract Embroidery" is embroidering wearable items for brokers, other embroiderers, ad specialty firms and screen printers at a wholesale rate. The customer of a contract embroiderer usually supplies the items to the factory and only pays the factory for the embroidery service. Commercial Embroiderers offer their services to the public and supply the wearable items.
