One of the most common questions we get at AIIM Choices Plan Managers is: “Can you actually refuse to pay my NDIS invoice from my provider?” The short answer is yes. And while it might feel like a roadblock at first, a plan manager’s “no” is often the most powerful shield you have in the NDIS.

In 2026, with the introduction of the NDIS “New Framework” and stricter 2025–2026 Pricing Arrangements, the rules around what can and cannot be funded have become much more precise. When an NDIS plan manager flags an invoice, they aren’t trying to be difficult; they are performing a critical compliance check that protects your funding from being clawed back later by the NDIS (ouch!).

So, what does it actually mean when your NDIS plan manager says no to an invoice? Let’s walk through the most common reasons and how each one helps protect your funding.

How NDIS Plan Managers Protect You Against “Over-Charging”

NDIS plan managers protect you from overcharging by checking that all invoices follow the NDIS price limits. The NDIS sets strict maximum price limits for almost every type of support. If a therapist or support worker sends an invoice that is even a few dollars over the NDIS Support Catalogue limit, the NDIS will automatically reject it.

If NDIS plan managers were to pay for that overcharged invoice out of your budget, you would be left with a debt when the NDIS eventually audits the plan. By saying “no” to an incorrect rate, we encourage the provider to correct their billing, ensuring you only pay the fair and legal rate. 

How Plan Managers Flag “Non-NDIS” Supports

NDIS plan managers flag non-NDIS supports to make sure your funding is only used for approved and relevant services. The 2026 NDIS rules have a specific list of what is considered a Funded Support versus a “Lifestyle Expense”. Sometimes, a provider might unintentionally bill for something the NDIS considers an everyday living cost, like general groceries, rent, or a gym membership that isn’t specifically linked to a disability-related therapy goal.

If we pay for a non-fundable item, the NDIS may view it as a misuse of funds. When we reject these invoices, we protect you from compliance risk. We work with you to find an alternative solution that still meets your needs without breaking the rules.

What is “Double-Dipping” & How Can Plan Managers Prevent It?

Double-dipping happens more often than you’d think: a provider accidentally sends the same invoice twice, or two different providers bill for the exact same hour of service. Our NDIS plan managers at AIIM Choices are dedicated to catching these duplicates instantly. By saying “no” to a duplicate or overlapping invoice, we ensure that your funding is spent correctly.

What Plan Managers Do to Ensure Service Delivery

NDIS plan managers help ensure you only pay for services you actually receive. As your NDIS plan manager, we act as a second pair of eyes. When we say “no”, it is a barrier against potential fraud or overservicing. We ensure you only pay for the support you received.

How Plan Managers Catch “Back-Dated” or Out-of-Plan Invoices

NDIS plan managers check invoice dates to ensure they match your plan period and funding rules. The NDIS uses staged funding periods where funding cannot be interchanged between periods. 

For example, if your plan runs from 1^st of October 2024 to 31^st of September 2025, then you cannot claim funds in your current plan period from previous plans. This would need to be submitted as a manual claim.

If a provider is late sending an invoice and tries to claim it against the wrong period, the NDIS will reject it. Following the completion date of a plan, the service provider must submit their invoices within 3 months of plan end date.
