Can I pay in KRW?

In order to avoid an extra charge of Korean 10% VAT, the payment has to be in USD. If we receive a transfer from an another Korean bank or KRW via Wise, it will not be considered as an export and we will be charged 10% VAT. In this case, we would have to charge our customers. This came up recently during our tax review and to comply with all the tax laws we have to accept payments in USD.
