because the screen message on the Banking app said the account had to been frozen due to registered phone number not matching the account. AIS made sure my details were correct, copied passport and gave me a print out of details to give the bank.
Anonymous participant I think the reason they say "tax invoice" as apposed to just "invoice" is because in providing a tax invoice shows you're a legit/registered entity/business as these will have your company numbers and any tax details on, whereas an invoice could be given by anyone and not give as much detail..
Anonymous participant yeah that's what they are after, as long as it's the legal format in your country for invoicing and shows any VAT info. If I were you id give just a select few that cover that date range, not all of them.
