Attached invoice is fine but it should really be reissued and the name on the invoice should be
Klassisk Investment Limited
7A Chin Bee Drive
Level 3
Singapore 619858
If the hotel can’t issue an invoice to KIL then make the payment to GM from CFFT and then you will rebill Singapore and Angeline will tell you what to do for this
Its better if the agreement with hotel is with Singapore but its not critical and at this stage I want to do what is simplest for you.
Do you have all the details of GM and flights, otherwise I will get Judy to chase
