Accounts payable is a current liability: what the contractor owes suppliers, subcontractors and other vendors for work and material already received. What customers owe the contractor is accounts receivable, an asset on the other side of the sheet. Cash is its own asset line and is separate from either. And the owner's investment is contributed capital inside equity, which is neither a receivable nor a payable.
