Automation of Transporter Liability and Loading Labor Liability Through Delivery Note

Hello
Is it possible To automate Transporters Liability and Loading Labor Wages through Delivery Note Creation.
According To Our Current Practice We Create Service AP Invoice in Concern BP Ledger and Hit Our Operational Expenses (COGS).
Now The Owner Says To Automate This Activity With DO Creating Liability of Transporter and Labors with a Constant Per Unit Price. Mean To Say If we Sold 10 Units And we Pay 10$ per Unit for Transport so it should hit 100$ To Transporter B.P Account and If 1$ Per Unit for Labor Loading then DO Should Hit 10$ to Loading paybales
