What must an NDIS invoice include?

A compliant NDIS invoice needs the provider's name, ABN and contact details, an invoice number and date, the participant's name and NDIS number, the dates the support was delivered, a clear description of the support, the relevant support item detail, unit price and quantity, correct GST treatment, the total amount, and payment details.

Why was my NDIS invoice rejected?

Common reasons include a description that doesn't match an approved support, service dates outside the current plan period, charges above the current price limit, incorrect GST, unitemised travel or cancellation fees, mismatched participant details, or insufficient remaining budget in that support category.

Can plan-managed participants use unregistered providers?

Plan-managed participants can generally use both registered and unregistered providers where this is permitted under current NDIS rules, which is one of the advantages of plan management. Some supports have specific registration requirements, so check the current position on the NDIS website or ask your plan manager.

Where do providers send invoices?

Send invoices to the participant's plan manager using the details on the service agreement or referral. If you're not sure where to send an invoice for a Forward Planning Plus participant, contact us and we'll confirm the right process.

NDIS invoice requirements: what a compliant invoice must include

A compliant NDIS invoice needs provider and participant identifying details, correctly dated service information, a clear description of the support, itemised pricing that matches current NDIS price limits, correct GST treatment and valid payment details. Missing or mismatched detail is the most common reason invoices are delayed rather than processed.

What a compliant NDIS invoice must contain

These are the fields providers should check before submitting an invoice for an NDIS-funded support.

Required NDIS invoice fields and why each one matters
Field	What it must show	Why it matters
Provider name and ABN	The registered business name and Australian Business Number of the provider issuing the invoice.	Confirms who is claiming payment and lets the plan manager verify the provider is who they say they are.
Provider contact details	A phone number or email address for the provider.	Needed if the plan manager or NDIA needs to query a line item before it can be processed.
Invoice number and date	A unique invoice number and the date the invoice was issued.	Prevents duplicate claims and confirms the invoice falls within the plan's active dates.
Participant name and NDIS number	The full name of the participant and their NDIS number.	Matches the claim to the correct participant's plan and budget.
Service dates	The date, or date range, the support was actually delivered.	Claims must relate to supports delivered inside the current plan period.
Description of the support delivered	A clear, plain-language description of what was provided, not just a support item code.	Lets the plan manager confirm the claim matches an approved support in the participant's plan.
NDIS support item and line detail	The relevant support item number from the NDIS Support Catalogue, where applicable.	Confirms the claim maps to a funded category and budget in the plan.
Unit price and quantity	The rate charged per unit (e.g. per hour) and the number of units delivered.	Allows the total to be checked against current NDIS pricing arrangements and price limits.
GST treatment	Whether GST applies, and if so, that it is itemised correctly for the support type.	Most NDIS supports are GST-free, so incorrect GST is a common reason invoices need correcting.
Total amount	The total amount being claimed for the invoice.	Must equal the sum of the line items, including any GST, travel or cancellation charges shown separately.
Payment or bank details	The account the payment should be made to.	Payment cannot be released without valid, matching payment details.
Travel or cancellation charges	Any travel time, travel costs or short-notice cancellation fees shown as separate, clearly labelled line items.	These are only claimable in specific circumstances, so they need to be identifiable rather than folded into the service fee.

Support item detail and price limits change over time. Always check the current NDIS Pricing Arrangements and Price Limits on the NDIS website before invoicing.

Why NDIS invoices actually get rejected or delayed

1
The description doesn't match an approved support in the participant's plan.
Fix: Use plain language that matches the support category and, where relevant, the correct support item number.
2
Service dates fall outside the participant's current plan period.
Fix: Check the plan's start and end dates before invoicing, and split invoices that straddle a plan rollover.
3
The total charged exceeds the current NDIS price limit for that support.
Fix: Check the current NDIS Pricing Arrangements and Price Limits before setting your rate.
4
GST has been added to a support that is GST-free.
Fix: Confirm the GST treatment for the specific support item before invoicing.
5
Travel or cancellation fees are bundled into the service fee instead of itemised.
Fix: List travel and cancellation charges as separate, clearly labelled lines.
6
The participant's NDIS number or name doesn't match plan management records.
Fix: Confirm participant details at the start of service, and use them exactly as recorded.
7
There isn't enough budget remaining in the relevant support category.
Fix: Check current budget balances with the plan manager or participant before delivering additional supports.

How Forward Planning Plus processes invoices

Valid, correctly submitted invoices are processed within 1–2 business days. We check each invoice against current NDIS pricing and the participant's available budget before it is claimed, and we contact the provider directly if something needs correcting.

Processing is the step we control. Final payment timing can also depend on NDIA processing and whether we need to clarify details with a provider.

For more on how invoices, payments and reimbursements work end to end, see our guide on how NDIS invoices, payments and reimbursements work, or read about common invoice mistakes that delay payments. If your current plan manager isn't processing invoices reliably, you can switch NDIS plan managers without needing NDIA approval.
