Invoice payment query

I will be registering for NOV26 L2, now the early bird deadline is 15 april and INVOICE PAYMENT deadline is 2 july.

From what I read about this method of payment is institure will generate an invoice with all the details and I have to go my bank and transfer the funds directly to their account

Now if today I generate an invoice does that mean I can pay anytime before 2 july? Like I can generate the invoice but maybe go to the bank in June(30 days before invoice deadline).

Also let me know anything I should be careful about before making this payment.
