How to test a marketplace switch
Start with fee math, but do not end there. A platform with lower fees can still lose if the buyer pool is weaker, the listing format is a bad fit, or the expected sale price drops after the move.
Use the same sale price first, then run a second pass with the price you believe the target marketplace can actually support. The useful switch is the one that improves net payout after both fee structure and buyer demand are accounted for.
