Supplier invoice auditing for growing businesses

Live demonstration
One invoice. Four lines. £290 back.
A real-looking print invoice, checked the way InvoiceHawk checks yours: each line against the price you agreed, the discounts you were promised and the fees you never signed up for.
- Matches what you agreed
- Money you're owed
Example: InvoiceHawk checks a four-line print invoice and finds £290.00 owed: an unagreed energy surcharge of £108.75 and a missing 5% volume discount of £181.25.
Six ways suppliers quietly take more.
None of them look like much on one invoice. Across a year of deliveries, they add up.
Missing discounts
The volume discount you negotiated, quietly left off the bill.

Surprise surcharges
Energy, fuel and admin fees that were never part of the deal.
Energy surcharge 3%Never agreed
Shrinking packs
Same price, less in the bag. The per-kilo cost is what counts.

Maths errors
Lines that don't add up, always somehow in the supplier's favour.

Duplicate invoices
The same invoice sent twice, so it can be paid twice.
