A sample answer to question 1

Talk me through the purchase-to-pay process from receiving an invoice to the supplier being paid.

It begins with a purchase requisition and an approved purchase order. When goods or services arrive, a goods received note is created. The supplier's invoice then arrives, ideally by email into a shared mailbox or through an OCR tool, and I would check it is addressed correctly, has a valid VAT number and sensible dates, and that it is not a duplicate. I match it to the purchase order and goods received note, and any price or quantity differences go back to the buyer for resolution. Once matched, I code it to the right nominal account and cost centre, post it to the purchase ledger, and route it for approval within the authority limits. Approved invoices are then scheduled into a payment run according to agreed terms, usually 30 days, and payment is made by BACS or Faster Payments after a second person authorises it. Finally, I send remittance advices and file everything for audit.

Common mistake to avoid: Skipping controls; forgetting the audit trail
