What remains on the original invoice, and what is the total parts cost in this example?

$312 less the $300 credit leaves $12 on the wrong-side lamp. The correct lamp costs $340, so the two transactions leave $352 of net parts cost before tax. The expected $300 credit stays open between pickup and posting.

Run the handoff

  1. Receive the shipment as an exception. Return the wrong lamp and order its replacement. Ask parts staff to show what is physically available to fit.
  2. Post the $300 memo on a later date. Have accounting trace the remaining $12 without reducing the correct lamp’s cost.

Where AutoHound fits

AutoHound describes purchase orders, invoice matching, return authorizations and allocation of vendor credit memos. Ask the parts lead to work the queue while accounting checks the cost trail. Read the AutoHound field guide.

What to record

A part marked returned and a credit marked received are two different events. Look for separate dates and evidence. Write down the role, screen and document that prove the result.
