Just received confirmation that my 3 GIROs are all up and ready. (2xUOB CC, 1xCDA) Whole approval process took about 1 month
I clarified with the CSO regarding the min payment for CC too. Say the bill $300, and you have paid $299, GIRO will still be triggered and deducts the min amount (provided you chose min amount in the GIRO form). Any excess will naturally be offset for next bill
Not sure about 'Pay Min Amount' but experience has shown that with a 'Pay Full Amount', as long as payments are paid prior to a certain trigger date, there will be no excess.
Thus, if $900 have already been paid, GIRO will pay exactly $100.01 by a certain trigger date (usually 3-4 days before due date) for a statement generated on 20 May and shows:
Total Payment Due: $1000.01
Minimum Payment Due:$1000.01
Payment Due Date: 11 June
If $100.01 is paid too near the GIRO trigger date, it is likely that GIRO will still proceed and there will be $100.01 excess for the next bill.
'Pay Min Amount' carries a risk of interest charges if total payments do not add up to the Total Payment Due.
