ACC invoice review process

If you want to formally dispute an invoice on behalf of a client, you can apply for an independent review.

Review process at a glance

  • You must complete the ACC33 Application review (PDF21K) form and send it to us within three months of the invoice date.
  • On receipt of the application review form, we will appoint an independent reviewer.
  • Together with the reviewer, we will gather any further information required. You can also submit any additional information you think is relevant.
  • The review will take place within three months of application. You will be invited to attend, along with your client.
  • A decision will be made within 28 days of the hearing, and you will receive a copy of the reviewer’s decision soon after that.
  • If either we or your client disagree with the decision, you may appeal to the District Court.
  • You can withdraw a review application at any time.
