The problem

Cross-border contractor invoices on a major infrastructure project needed checking before payment, to make sure the project paid only for what had actually been shipped.

What was done

  1. Audit of invoices

    Contractor invoices were audited line by line.

  2. Reconciliation to manifests

    Each invoice was reconciled against the shipping manifests at international ports.

  3. Differences resolved

    Where invoice and manifest did not match, the difference was identified before payment.

The resultOverpayment risk eliminated

Why this matters for your business

Paying for more than arrives is one of the most common leaks in any business that buys goods. If invoices are not matched to delivery records, short deliveries and double charges are paid without anyone noticing.

Signs it could apply to you

  • You buy goods or materials in volume
  • Invoices are approved without checking delivery notes
  • Deliveries arrive in parts, across several invoices
  • You have never matched a year of invoices to deliveries

How we would check it: Money you overpaid suppliers: we check every supplier invoice against the order, delivery record and agreed rate, and give you the evidence and a claim letter for each supplier.
