An invoice controls review Finance Career Foundry — original fictional practice exercise Review a fictional invoice log and turn exceptions into an evidence request. TASKS 1. Flag duplicate invoice references and payments without recorded approval. 2. Calculate the value requiring duplicate-payment investigation. 3. Write an evidence request and suggest a preventative control. Deliverable: one worksheet and a short written recommendation. Label your portfolio entry as a practice project using fictional data. WORKED CHECK INV101 appears twice: £2,400 is the potentially duplicated amount, not £4,800. INV102 is a £750 payment without recorded approval. These are exceptions for investigation, not proof of loss or fraud. Check source invoices, bank entries and approval records; propose duplicate detection and approval checks before payment.
