Hi,
Thank you for the reply. The current status is that I received money from MEET TAIWAN to my personal account. I was planning to refund Paul Liu and myself (who are payees of these reimbursements) and transfer the surplus to OCF.tw.
OCF.tw's reimbursement requires physical receipts and VAT ID/payer to be exact. These receipts have payer written as NCTU to reimburse via MEET TAIWAN for day trip, which has budget capped at TWD 96,000. The remaining TWD 36,115 was planned to reimburse through SPI, and I told NCTU no need to send back the physical receipt since reimbursing through SPI don't take them. I think I did a mistake here.
