Need help

HELLO actually i have a question regarding gst portal we haven't filed any return after gst, due to non maintaining any records. But, Now we are maintaining our database, but it will take time. so till then, can i submit amount through my bank for ledger balance. and when my data would be maintained, i can file return monthly through that cash ledger? Is there any problem? or is there any need to submit tax side by side instead of submit at a time? Please help me
