This is not a solution as billable expenses are only applicable in the case of time & material contracts versus lump sum contracts. The feeble attempt to resolve does not provide the appropriate data or reflect each customer's aging data on outstanding payables and neglects sufficient amounts of data. 

The request is simply to add the customer to the accounts payable aging detail report's customized fields. There is not a customized report in Quickbooks offering this important information and it impacts every construction and architectural firm, as well as their contractual obligations, using QBO.
