The time it takes to credit INR after invoice clearance depends on the payment method. Payments are received instantly into your BRISKPE virtual account, but settling into your Indian bank account usually takes T+1 day (transaction day + 1 working day).
Whereas payments via PayU or PayPal payment links can take T+2 days, or the time specified in your Merchant Service Agreement (MSA) to reflect in your Indian bank account.
