will we pay for next month if regular payment subsription is cancelled?

we dont want to pay $19 every month, just upgrade my account for 1 month trial.  i ask you if you recieve our payment and will we pay automatically for mext month?

If you subscribe, then cancel your subscription before the second month is billed, you will only be billed for a single month.  We have many users that upgrade for a month at a time when they have large events and things of that nature.  They then downgrade to a Free account when they no longer need the upgraded limits.
