When using the “Extra Cost” option in the bill, any additional charges entered (such as freight, travel, or handling) must be automatically added to the final price of the product in the customer invoice. At the same time, these extra costs should be recorded separately from the supplier’s original bill value. Merging them into the supplier’s purchase amount distorts the actual procurement cost and creates inaccuracies in the balance sheet by inflating the supplier liability instead of reflecting them as operational or landed expenses. The supplier bill should strictly represent the vendor’s invoiced amount, while all internally added expenses must be treated as distinct cost components that adjust the product’s effective landed cost without altering the supplier payable. This isn’t just a formatting issue — if you keep mixing internal expenses into supplier bills, you’re literally corrupting your financial statements. It will overstate payables, understate operating expenses, and your inventory valuation will become unreliable. That’s how people end up not knowing their real margins.
