“GMO Post Pay” is a convenient payment method which handles billing and collecting fees on merchant’s behalf.
This means that there is no debt collecting risk on merchant’s side.
This payment type is suitable to those who are reluctant to pay by credit card or preferring to pay after a merchandise is delivered.
GMO Post Pay is available at convenience stores, post offices (Yu-cho Bank), as well as other banks.
