Why Did My Plan Manager Decline an NDIS Payment? (And How to Fix It)

A plan manager usually declines an NDIS payment because the support category is not in your plan, the budget has run out, the service dates fall outside your plan, or the invoice has an error such as a missing ABN or wrong item code. Ask your plan manager for the exact reason in writing, then fix the invoice or the plan.

It is stressful when a provider says they have not been paid, or you see a "declined" or "paused" message on an invoice. The good news is that most declined payments have a simple cause and can be fixed within days. This guide lists the eight most common reasons, what each one means and what you can do about it.

Step 1: Find out the exact reason

Do not guess. A declined payment always has a reason, and your plan manager can tell you what it is.

• Check your participant portal or app. Many plan managers show a status for each invoice, with a short reason if it is paused or declined.
• Ask your plan manager. Contact them and ask for the reason in writing, by email or message. Having it in writing helps if you need to follow up later.
• Ask which invoice and which date. Note the provider name, invoice number and the amount, so you are talking about the same payment.

8 common reasons a plan manager declines an NDIS payment

1. The support category is not in your plan

What it means: Your plan has separate budgets, called support categories. If a provider invoices for a support that falls under a category you do not have, the payment cannot be made. For example, a therapy invoice may be declined if your plan has no capacity building funding for that type of support.

What to do: Ask your plan manager which category the invoice was claimed against. If the support is genuinely needed, talk to your support coordinator or the NDIS about it at your next plan review, or ask whether it can be claimed under another category in your plan.

2. Your budget has run out

What it means: There is not enough money left in that support category to pay the invoice. A payment can be declined in full or only partly paid.

What to do: Ask your plan manager for your current budget balance. Slowing down or changing your supports may help. If you have overspent, a plan manager may be able to submit a claim for the NDIS to assess, but this does not guarantee payment, so ask before booking more services. A plan review request may be needed if your needs have changed.

3. The service dates are outside your plan period

What it means: A plan can only pay for support delivered between its start and end dates. An invoice with dates before the plan started, or after it ended, will be declined.

What to do: Check the dates on the invoice against your plan dates. If a provider made a typing mistake, ask them to send a corrected invoice. If the service really was outside your plan, talk to your plan manager about what options are available.

4. The item code or price is wrong

What it means: Every NDIS support has an item code and a maximum price. An invoice with an old or incorrect code, or with a price above the NDIS limit for that support and location, can be declined.

What to do: Ask your plan manager what the problem is. The provider usually needs to send a corrected invoice with the right code or price. Our guide to NDIS price limits and plan management costs in WA explains how the limits work.

5. The invoice is missing details

What it means: A valid invoice needs the provider's details, including an ABN (or a supplier statement if they are exempt), the service dates, a description and the amount. Missing or wrong information, such as an incorrect participant's NDIS number, can stop the payment.

What to do: Ask your plan manager what is missing. The provider can send a corrected invoice. You can speed things up by asking providers to include your full details whenever they invoice.

6. The invoice does not match your service agreement or quote

What it means: If the provider charged more than the agreed price, added a service you did not agree to, or billed for something outside the booking, your plan manager may pause the payment to check with you.

What to do: Look at your service agreement or quote. If the invoice is wrong, ask the provider to correct it. If the invoice is right and you agreed to the change, let your plan manager know, in writing.

7. The support is not something the NDIS can fund

What it means: Funding must be for supports that are reasonable and necessary and that fit the purpose of your plan. Everyday living costs and items not related to your disability support are usually not funded.

What to do: Ask your plan manager to explain why they believe the support is not eligible, and check the NDIS website or your support coordinator if you disagree. If you think the decision is wrong, you can ask for it to be looked at again.

8. You disputed the service or asked for payment to be held

What it means: You have the right to question an invoice. If you told your plan manager that a service was not delivered, or not delivered properly, they may hold the payment until it is sorted out.

What to do: Make sure your plan manager and the provider both know what is being disputed. Keep notes or messages. Once it is resolved, tell your plan manager so they can release or cancel the payment.

What if my plan manager still will not pay?

1. Ask for the reason in writing and keep a copy.
2. Ask what the next step is. Do they need a corrected invoice from the provider, more information from you, or a decision from the NDIS?
3. Raise a complaint with your plan manager. Registered providers must have a complaints process. Ours is on our feedback and complaints page.
4. Contact the NDIS. The NDIS helpline is 1800 800 110. Check the number on ndis.gov.au before you call.
5. Contact the NDIS Quality and Safeguards Commission if your complaint is not resolved. They handle concerns about registered NDIS providers.

How to avoid declined payments

• Tell providers you are plan managed and give them your plan manager's invoice email address.
• Ask providers to put your NDIS number, service dates and item codes on every invoice.
• Check your budget balance regularly, especially before booking a block of services.
• Write down what you agreed with each provider, including prices and how often they will visit.
• Tell your plan manager early if a service changes or if you have a concern about an invoice.

A plan manager who explains problems clearly and pays correct invoices on time makes this far easier. See our checklist for choosing an NDIS plan manager if you are thinking about a change, or read what NDIS plan management is and how to start.

Frequently asked questions

Why was my NDIS invoice rejected?

The most common reasons are a support category that is not in your plan, an empty budget, service dates outside your plan period, an incorrect item code or price, or missing details such as an ABN. Ask your plan manager for the exact reason.

What happens if my NDIS budget runs out?

Your plan manager cannot pay invoices from a category with no funds left. Ask for your balance, talk to your support coordinator, and consider asking for a plan review if your needs have changed.

Who do I call if my plan manager will not pay?

Start with your plan manager and ask for the reason in writing. If it is not resolved, you can call the NDIS helpline on 1800 800 110, or contact the NDIS Quality and Safeguards Commission about a registered provider.

How long does a plan manager take to pay an invoice?

It depends on the plan manager. Ask yours how long payments usually take and how they tell you when an invoice is paused. Choose a plan manager that gives you clear statements and quick updates.

Can I change my plan manager if payments keep being declined?

Yes. You can change plan managers during your plan. Your NDIS funding does not change when you switch. Ask your current plan manager for notice requirements and make sure the new one knows about any unpaid invoices.
