You are right. Although I am not using Smartpay but still sharing how to get it done for SBI Cashback card.
Lets simplify first for other people here on why it fails?
Suppose your SBI Cashback card bill generated on 03-May-2025 with amount Rs.50000.
Your cashback for this statement was Rs.2500 (assuming all this 50K txns were online and had 5% cashback applicable).
Now on 4th SBI will credit Rs.2500. Your bill due now stands at Rs.47500 (50000-2500).
SBI allows maximum 5% extra on outstanding due: Rs.47500 + 5% = 49875. Now Smartpay will have 50K but you can not pay more than 49875 now. Due to this smartpay txn will fail.
How to get rid of this?
Before smartpay date arrives for auto-payment like if due date is 23-05-2025 then smartpay will trigger on 19-05-2025. Before this do txn of Rs.125 or more more depending on what due left you have. Smartpay won't fail now.
Current o/s on SBI Cashback card should be equal or greater than what smartpay bill value has.
