NDIS Invoice Template (2026): How to Invoice NDIS Clients Correctly

Creating a regular invoice is simple — until you start working with the NDIS. Then, small details suddenly matter a lot.

Under Australia’s National Disability Insurance Scheme (NDIS), invoices must follow specific structure and pricing rules. If something is missing — even a support item code — your invoice can be delayed or rejected.

Whether you’re a sole provider, therapist, or small service business, this guide explains how to create an NDIS invoice template that gets paid without issues.

When You Must Issue an NDIS Invoice

If you provide services under the NDIS, you must issue an invoice whenever you:

  • deliver a support or service
  • claim payment from a participant, plan manager, or the NDIA

Example:
You’re a support worker providing 3 hours of community access support. After the session, you issue an invoice reflecting the service delivered — not before.

Unlike standard freelancing, invoices here are not just for payment — they are also used for plan tracking and compliance.

What an NDIS Invoice Must Include

NDIS invoices are more structured than typical business invoices.

At a minimum, your invoice should include:

  • Your business name and ABN
  • Provider contact details (address, email, phone)
  • Invoice number (recommended for tracking and clarity)
  • Invoice date
  • Participant’s full name
  • NDIS number (participant identifier)
  • Plan manager details (if applicable)
  • Description of supports provided
  • Date(s) of service (separate from invoice date)
  • Unit type (e.g. hours, kilometres)
  • Quantity
  • Unit price
  • Total amount
  • NDIS support item code
  • GST (if applicable)
  • Payment details (e.g. bank account)
  • Due date

Example (core structure)

Instead of writing:

Support services — $150

You should structure it like:

Assistance with daily life
3 hours × $50 — $150
Support item: 01_011_0107_1_1

This level of detail is essential for approval and reimbursement.

GST and NDIS: What You Need to Know

Most NDIS-funded supports are GST-free under Australian tax law, but not all.

GST-free supports

  • Personal care
  • Therapy services
  • Most disability supports

Taxable (GST applies)

  • Some non-core or additional services
  • Non-NDIS services billed separately
  • Certain items like equipment or mileage (depending on context)

Example:

Support services — $200
GST — $0 (NDIS GST-free support)

⚠️ Important:
GST-free is not the same as exempt — it means GST is not charged, but the service is still within the tax system.

Pricing Rules (NDIS Price Guide)

NDIS pricing is not flexible like typical freelancing.

  • Maximum rates are set by the NDIS Pricing Arrangements and Price Limits
  • You cannot charge above the cap

Example:
If the hourly limit is $67, charging $75 may result in rejection.

👉 Always match your invoice rate with the official price limits.

Step-by-Step: How to Create an NDIS Invoice

Let’s walk through a realistic example.

You’re a sole trader providing support work.

Start with your business details, ABN, and contact information. Then add participant information and (if relevant) plan manager details.

Now describe the service clearly:

Community access support
4 hours × $65 — $260

Add the support item code:

04_104_0125_6_1

Make sure you include service dates separately from the invoice date.

Then finalize the invoice with total, GST status, payment details, and due date.

At this stage, many providers prefer not to build invoices manually — especially when dealing with item codes, pricing limits, and compliance requirements. Tools like InVault can help generate structured invoices and reduce formatting errors, which is useful if you manage multiple participants.

Types of NDIS Invoices

Not all invoices are used the same way.

A standard invoice is used after delivering services.

A progress or periodic invoice may be used for ongoing support delivered weekly or monthly.

In some cases, providers also include travel or additional costs — but these must follow NDIS rules and be clearly itemized (for example, kilometres travelled).

Special Rules to Watch

NDIS invoicing has a few strict requirements.

Plan-managed vs NDIA-managed

  • Plan-managed → invoice goes to plan manager
  • NDIA-managed → claim is submitted via the portal

This affects how invoices are processed, not how they are structured.

Support item codes are mandatory

Missing or incorrect codes can delay payment.

Always match:

  • service delivered
  • correct NDIS item code

No overcharging

Even small discrepancies above price limits can cause rejection.

Cross-Border / Non-Standard Cases

NDIS is an Australian system, so:

  • invoices are always tied to Australian rules
  • currency is AUD

However, providers working remotely (e.g. telehealth) must still:

  • follow NDIS pricing
  • use correct item codes

Currency and Language

  • Currency: AUD (Australian dollars)
  • Language: English

Invoices must be clear and readable for plan managers and NDIA processing.

Deadlines

Invoices should be issued:

  • after service delivery
  • as soon as possible for timely payment

Delays can affect:

  • cash flow
  • claim processing

Record Keeping

NDIS providers should keep records for at least 5 years, in line with Australian tax requirements.

Keep:

  • invoices
  • service agreements
  • session notes

This is important for audits and compliance.

Common Mistakes

A common mistake is missing the support item code.

Another is using incorrect pricing that doesn’t match NDIS limits.

Some providers also forget to include payment details or the participant’s NDIS number — which can delay processing.
