What is commercial use feature? please explain anyone.
If a gig has a “commercial use” extra, you would need to use that option to be able to use the delivery commercially eg. for business purposes (ie. making money from it) eg. if you wanted to re-sell it or use it as part of a product that you will sell. If you only want to use it for personal use you don’t need that extra.
If the gig doesn’t have a “commercial use” option/extra buyers will automatically get the rights to use it commercially (unless stated otherwise in the gig).
You can see the Fiver terms of service page for their description about it.
Thank you so much @uk1000
