There is no way 1 person does everything. I ran my Interior Design business from my home for the last 20 years before I retired. No direct employees, I had a fleet of independent consultants, Architects, Decorators, Draftspersons, Engineers, Acoustic Consultants .... that helped me as needed on large or small projects, via hourly or sub-contracts the client may or may not know about..
In my case, a business service (no product), I billed my direct consultants hourly work on my invoices the client saw. I approved sub-consultants invoices like acoustic engineers, hvac engineers ... before client paid them directly.
Clients may or may not have met them along the way. Products, you never knows who is doing what.
