Ask Should freelancers explain platform costs to clients?

[Edward22]

Some freelancers believe that being open about platform costs helps build trust, since clients get to see exactly why certain rates are set the way they are. Others think this kind of explanation is unnecessary and even unprofessional, since business costs are usually the seller's own responsibility to manage quietly. There is no single right answer here, and different clients may react differently depending on their experience. Do you think freelancers should openly explain these platform costs to their clients directly?
