submitting meter reading

hi this is my first time joining with bulb and first time ever going via direct debit… my question is do i submit my meter readings once a month be it the start or the middle of the month? and if i owe money say for that month how do i pay it? or do bulb just take out the extra i owe on top of my monthly diretc debit.thanks
