Single word for "product or service"
Offerings works quite well.
a thing produced or manufactured for entertainment or sale. –Google
"Companies won't succeed unless they can provide their offerings at a fair price."
By the definition used in economics, products include services! Not all products have to be tangible goods. It is perfectly acceptable to say, for example, that a haircut is a product of a barbershop.
Good, but that seems to be more of a product and less of a service.
'produce wanted goods' sounds not bad.
