Our approved sales volumes are on a rolling 24 hour time frame. This means that when an invoice is fully paid, the paid amount is reduced from your approved sales volume for 24 hours.
Let us say you have an approved sales volume of $100 per day and your client creates and fully pays an invoice for $25 on January 1, 2014 at 12:00 UTC. Your approved sales volume will be reduced by $25 until January 2, 2014 at 12:00 UTC. On January 2, 2014 at 12:01 UTC, your approved sales volume will be reverted back to $100 until another invoice has been fully paid.
