you do not want to submit the data until you have that whole application filed out, and that means, proof of your location (that you're in Lao) proof of funds, CHECK the data that the MRZ auto filled when you scanned your passport, etc
It's not a race, 🙂 get it right (y) check it carefully, THEN submit it once you have it complete and ready to go
You'll get the confirmation (which you need to PRINT) and then you go to the consulate to pay for the visa (showing that print out to get in the gate)
