Dear K Toon,
Do we have deadline on the submission? It will not be possible if the submission is the end of the month and expect by the first week of next month.
T&E will need to comply with HR. For other items, we will need to look at when the documents arrive to BKK. Then, plus two weeks or more to meet Friday processing date.
Vendor payment is 30 days due date. So, it can be after the first week.
We may need to clarify the information.
