I dont see anything about this.
Can I sell products on upwork, like lets say I designed a business card for my client and I want to offer my client the service of printing the business cards and selling it to them ata retail price. I would go through upwork so there wouldn't be any violation or anything.
But is there something against that? what would be the pitfalls of doing that?
Given the nature of the product you mentioned looking to offer on Upwork, it can potentially be in violation of Upwork ToS. In order to confirm, please do submit a support request with specific details so we can advise. Thank you.
Goran, aside from OP's direct discussion with CS, it would be great if you or someone from Upwork could provide a general answer here. It's hard to see what aspect of TOS could be violated by the type of contract OP described--she clearly said all payment would go through Upwork.
It`s hard to give a specific answer on this when we don`t have all of the details, this type of concerns are reviewed on case to case basis.
I will follow up with our team and will share more details about a similar scenarios soon.
