Goods are products, such as bicycles or candles. Services are activities performed for the benefit of someone other than you or your company, such as bicycle repair services or catering.
The difference between goods and services can sometimes be confusing. Are your customers paying you to receive a product or to receive a specific activity? If your customers are paying you for a product, such as a bicycle, then you have a good. However, if your customers are paying you to perform an activity, such as repairing a bicycle, then you have a service.
You may list both goods and services in an application.
