    Coral is sitting in a chair facing the camera. A pot plant, water jug, cup of water and pen and notepad sit on a small table beside her.


    When it comes to invoicing us for the treatment and rehabilitation services you’ve provided to our clients, we want you to get paid as soon as possible.

    To help with this, I’m going to share with you what to include on your invoice, how to get paid faster and some common reasons why payments are declined or delayed. Let's get into it!

    Once you've provided treatment or rehabilitation services for a client, you need to invoice us for the services you’ve provided. It's important to remember we can only pay ACC registered vendors and providers once we've accepted a claim and received your invoice.

    Like I said, we want you to get paid as soon as possible. To do this, we need to have the right information to process your invoice. This includes everything you would normally put on a GST invoice, plus five extra important details: The claim number, the client's full name, your Provider ID, our service code and a purchase order number if applicable.

    The claim number and PO number are important so we can match your invoice to the right claim.

    If your services require a PO you can find both the claim number and service code in the purchase approval letter, otherwise your contract will have this information. Our website also has a list of all service codes and rates under Cost of Treatment Regulations.

    The easiest way to get paid by us is to invoice electronically through your Practice Management System or by using our online services. This lets us get payment to you within 8 business days. To see if this is the right option for you, contact our Provider Helpline. You can still email or post us invoices but these need to be manually processed, which will take longer to issue payment.

    Another way to get paid faster is to send in your invoice as soon as you can. Ideally, we would like to receive it no later than 2 months after service, but it MUST be received within 12 months.

    Screen cuts back to Coral in the chair.


    The three most frequent reasons invoices might have a delayed payment are:

    Duplicate invoicing. So, make sure you're not billing for the same service more than once, as this will result in a delay.

    Another common issue is invoicing us instead of accredited employers. Payment of services under Accredited Employer claims are managed by the respective employers and not by us.

    So, ask your patient if they are working for an Accredited Employer first. There's also a list of Accredited Employers and their contact details on our website.

    And finally, making sure that the invoiced items have prior purchase approval. If we have purchased a service from you, you need to quote the purchase approval number on your invoice, use the approved service code and make sure that the invoiced service is between the approval dates.

    If you're having problems or you haven't received a payment from us, you'll find a reason code on your remittance advice that will give you more detail.

    If you've invoiced us online, you can view this under the 'payment advice' tab, and there is a full list of codes and what they mean on our website.

    If you need to get in touch with us, the Provider Helpline is your first port of call – you can reach them by phone or email during business hours.

    When to invoice us

    We generally expect providers and suppliers to invoice us within two month of the date of service.

    All invoicing must be submitted to us within 12 months of the service you’ve provided. For treatment injury claims, it’s the date the treatment injury was determined.

    Sending invoices online

    You can submit invoices online and keep track of them using our eBusiness Gateway or your practice management system (PMS). Our online systems are easy to use and you’ll get paid faster than doing it manually.

    Getting set up online

    Schedules, referrals and approval letters

    If you invoice online, you don’t have to send the printed schedule or copies of referral forms and approval letters. We may ask to see them to validate your claims and services provided, so make sure to keep copies of these on file.

    Sending invoices manually

    If you can’t submit your invoices through one of the online services, you can post them to us. They take longer to process and you don’t get paid as quickly.

    All invoices need to meet the Inland Revenue tax invoice standards and include:

    • the full ACC client name
    • the client’s claim number
    • the name (or trade name) and GST number of the vendor (if applicable)
    • our name, ie ACC
    • the date the invoice was issued
    • the correct service codes (using the wrong ones will hold up your payment)
    • a description of the goods and services supplied
    • the quantity or volume of the goods and services supplied, eg hours of physiotherapy, number of photocopied pages of a report
    • the amount, excluding tax, charged for the supply
    • if you charge an hourly rate, add the time you took to give the service
    • the GST and the total amount payable for the supply. Or a statement that GST has been included in the final price.

    Adding purchase order details to your invoice

    If a recovery team asks for your services, they’ll provide you with a purchase order that covers what services we’ve approved. Make sure you include on your invoice the:

    • purchase order number
    • service item code or description you're invoicing against
    • terms of the purchase order, eg quantity and service dates
    • address on the purchase order request or one of the addresses below.

    If the services you've provided exceed or have changed from what has been approved on the purchase order, contact our recovery team to have the purchase order reconsidered before submitting.

    Where to post your invoices

    Where you send your invoices depends on where and what services you've provided.

    Where to post your invoices

    Ordering manual ACC47 or ACC40 forms

    You can order manual ACC47 or ACC40 (Invoice for Services) tax invoice forms from the stationery order line:

    Phone 0800 802 444

    When you'll receive payment

    Processing times for manual billing or invoices sent by email are currently at 15 working days. 

    Once we have your invoice, you'll usually receive payment after:

    • eight working days for electronic billing
    • 10 working days for manual billing or invoices sent by email.

    Invoices that require investigation will result in longer processing times. We prioritise electronic invoices and encourage you to shift to electronic billing if you don’t already.

    Work with us using digital services like electronic billing 

    Receiving your remittance advice

    If you've invoiced us online, you can view your remittance advice any time under the 'payment advice' tab on the eBusiness Gateway. Please let us know if you don't want to receive remittance advice in the post.

    Guide to payment remittance advice access on eBusiness Gateway

    Phone 0800 802 444

    If you've invoiced us manually, a remittance advice will be sent to you by post to the address you have nominated.

    You should allow an additional week outside of payment timeframes to receive remittance advice.

    If you need to change the address where you receive your remittance advice, complete the change of vendor details form.
