NDIS Invoicing Requirements: Complete Checklist
Every NDIS invoice you send must meet specific requirements set by the NDIA. Missing a single field can delay payment or trigger a compliance review. This guide covers everything your invoices must include.
Important reminder
An invoice can only be for one participant, but can include multiple supports delivered to that participant. Plan managers must also include the ABN of the third-party provider.
Required Invoice Fields
Provider's NDIS business name
Your registered business name as it appears in the NDIS provider portal.
Provider's ABN
Your Australian Business Number. Plan managers must also include the third-party provider's ABN.
Participant's name
Full legal name of the NDIS participant being supported.
Participant's NDIS number
The participant's unique NDIS reference number (previously called NDIS number).
Participant's address
Required for Specialist Disability Accommodation (SDA) supports — include postcode.
Support item number
The support item code from the NDIS Support Catalogue (e.g. 01_011_0107_1_1).
Amount and quantity for each unit
For example: "$51.09 each × 2 units". Do not just list a total.
Claim type
Specify if this is standard, non face-to-face support, provider travel, short notice cancellation, or an NDIS Requested Report.
Date(s) support was delivered
The actual dates the supports were delivered — not just the invoice date.
Total invoice amount
The grand total of all line items on the invoice.
GST component (if applicable)
Most NDIS supports are GST-free. Note this explicitly. Include GST amount only if applicable.
Claim Types Explained
Your invoice must specify the claim type for each line item. This tells the NDIA how the support was delivered.
| Claim Type | Code | When to Use |
|---|---|---|
| Standard | STD | Direct service delivery as per service agreement. |
| Non Face-to-Face | NF2F | Phone support, report writing, care coordination not done in person. |
| Provider Travel | TRAV | Travel by the support worker to the participant's location. |
| Short Notice Cancellation | CANC | Participant cancels within 2 business days — provider can claim up to 100% of quoted rate. |
| NDIS Requested Report | REPW | A formal report requested by the NDIA. |
GST and NDIS Invoices
Most NDIS supports are GST-free under the GST Act. You should clearly state "GST-free" on your invoices. You are not required to add GST to support prices listed in the NDIS Price Guide. However, some ancillary services (such as non-disability-related travel or consumables) may attract GST — consult the ATO website for GST-free NDIS supplies .
Finding Support Item Numbers
Every support you bill for must have a valid support item reference number from the NDIS Support Catalogue . These are structured as: XX_XXX_XXXX_X_X.
The number maps to a specific support category and type. Using the wrong item number will cause your claim to be rejected. Always verify against the current NDIS Pricing Arrangements and Price Limits document.
