Bill Pay limit is the portion of your total credit limit that you can spend towards Bill Pay. Like your credit limit, your Bill Pay limit is determined by a variety of factors. You can see your Bill Pay limit by going to Settings > Company & Personal > My Credit & Bill Pay.
When making a payment, how much you have available to spend on bill pay is equal to the minimum of the amount available between your credit limit, bill pay limit, and weekly/monthly limit. For example, if you do not have a weekly / monthly limit and you have not used any of your Bill Pay limit, but only have $5,000 available on your credit limit, then you can only spend $5,000 on Bill Pay.
To free-up your Bill Pay limit, you will need to pay Parker for all billing periods before and including the billing period during which your last recent Bill Pay transaction was made. For example, if your last recent Bill Pay transaction was made 30 days ago and was for $10,000, then to make $10,000 of your Bill Pay limit available, you would have to pay Parker for all Billing Periods that took place before 30 days ago as well as for the Billing Period that took place 30 days ago.
