Work Log Payable:
The Payables tab in the job settings is where you can add the individual charges paid to the vendor for each of the job's payables and, if necessary, include or remove any discounts and/or surcharges. You can also override the minimum charge defined in the vendor's price profile and use the job's total value instead.
