How do you calculate the verified cost of a temperature event?

Match lot, invoice, and product disposition; calculate extra transport and labour from records.

Short answer

Link lot and quantity, purchase or sales invoices, return or disposal decision, and extra transport or labour records in one event file. Sum only realised, documented items and show estimates separately. This cost calculation does not determine whether goods are safe or saleable; the authorised quality owner must decide under the product procedure.

For a temperature event, file verifiable cost items tied to the same lot rather than one invoice total. Product quantity, event date, and disposition record should link each document.

Use purchase invoices or internal cost records for product cost; use receipts, invoices, and transport records for return, disposal, collection, and reshipment. Verify extra labour hours from work records.

Do not add unmeasured customer impact or lost sales to realised costs. If an estimate is needed, mark its method and assumptions separately; remove duplicate entries.

Compare event costs with dated quotes for preventive options. Product release, rejection, or disposal is a separate quality decision made by an authorised person under the relevant product instructions.
