Service agreements that protect both sides: a guide for NDIS providers

A service agreement is not just a formality. For NDIS providers, it is the document that defines what you deliver, what you charge, how you handle cancellations, and what happens when things go wrong. Get it right and it protects both you and the participant. Get it wrong and you risk underpayment, disputes, NDIS Commission scrutiny, and damaged relationships with the people you are there to support.

This guide is written for registered and unregistered NDIS provider operators who want practical, plain-English advice on building service agreements that hold up in the real world.

Why service agreements matter more than most providers realise

The NDIS Commission requires registered providers to have written service agreements in place before delivering most funded supports. But even unregistered providers who work with self-managed or plan-managed participants benefit enormously from having a clear written agreement.

Without one, you are relying on verbal understandings that are almost impossible to enforce. A participant or their family might dispute an invoice. A cancellation might go unpaid. A scope of support might be interpreted differently by each party. These situations are stressful, time-consuming, and often avoidable.

A good service agreement also signals professionalism. Participants and support coordinators are increasingly savvy about what a quality provider looks like. When a support coordinator is shortlisting NDIS providers for a participant, a provider who presents a clear, readable agreement stands out from one who hands over a dense legal document or nothing at all.

What the NDIS rules actually require

The NDIS Commission's Practice Standards and the NDIS Act set out the baseline requirements for service agreements with registered providers. Here is a plain-English summary of what the rules expect.

The agreement must be participant-centred

The NDIS Commission says the agreement must be written in a way the participant can understand. That means plain language, accessible formatting, and, where needed, an Easy Read version or a translated version. If a participant has a guardian or nominee, the agreement should reflect how decisions are made in their situation.

You must give the participant a copy of the signed agreement and keep a copy on file. This sounds obvious, but many providers skip it or delay it.

Pricing must align with the NDIS Pricing Arrangements

Under the NDIS Pricing Arrangements and Price Limits (updated annually by the NDIA), registered providers must not charge above the published price limits for each support item. Your service agreement must specify the support item numbers, the agreed price per unit, and how the support will be delivered (for example, in-person, remote, or a mix).

If you plan to charge for travel, non-face-to-face time, or short-notice cancellations, these must be spelled out in the agreement before you deliver any supports. You cannot add these charges retrospectively.

Cancellation policies must be explicit

The NDIS Pricing Arrangements include specific rules about short-notice cancellations. As of the current pricing arrangements, registered providers can charge for a cancellation if the participant gives less than the required notice (generally two business days for most supports, seven days for some specialist supports). But you can only charge this if the cancellation policy is written into the service agreement and the participant has agreed to it.

This is one of the most common compliance gaps. A provider delivers a support, the participant cancels at the last minute, and the provider tries to claim a cancellation fee, only to find it was never in the agreement. The claim is then rejected by the plan manager or disputed by the participant.

What every service agreement should cover

Whether you are a sole trader delivering community access or a large organisation providing supported independent living, your service agreement should address the following areas.

1. Who the parties are

Full legal name of the provider, ABN, and the participant's full name and NDIS number. If a plan nominee, parent, or legal guardian is signing on behalf of the participant, record their name and relationship clearly.

2. Scope of supports

Describe what you will deliver in plain terms. Reference the relevant support item numbers from the NDIS Support Catalogue. Be specific enough that both parties understand what is included and what is not. Vague descriptions like "community support as needed" cause disputes. Something like "community access support, up to 8 hours per fortnight, to assist the participant to attend social activities of their choosing" is far more useful.

3. Pricing and billing

State the agreed price per hour or per session. Specify whether GST applies (most NDIS supports are GST-free, but check your specific items). Explain how and when invoices will be issued and what the payment terms are. If you work with plan managers, note that invoices will be submitted to the plan manager rather than directly to the participant.

4. Cancellation and no-show policy

Write this out clearly. Include the notice period required, the percentage of the support item rate you will charge for a short-notice cancellation, and any exceptions (for example, where the participant was hospitalised). Align this with the current NDIS Pricing Arrangements.

5. Responsibilities of both parties

Be explicit about what you will do and what you expect from the participant. This might include things like: the provider will arrive at the agreed time; the participant will notify the provider by 5pm the day before if a session needs to be changed; the provider will keep a record of each support delivered.

6. How to raise a concern or make a complaint

Every service agreement must include information about how to raise a concern or complaint. This includes your internal complaints process and the participant's right to contact the NDIS Commission directly. The NDIS Commission's contact details should be included or referenced.

7. How the agreement can be changed or ended

Either party should be able to end the agreement with reasonable notice. Specify what "reasonable" means, for example 14 days' written notice. Explain how changes to the agreement will be made, typically in writing and signed by both parties.

8. Privacy and information sharing

Explain what personal information you collect, how you store it, and who you share it with. Reference your privacy policy if you have one. This is particularly important if you share information with other providers, support coordinators, or allied health professionals as part of a coordinated support arrangement.

Common mistakes providers make with service agreements

Even experienced providers make avoidable errors. Here are the most common ones.

• Using a generic template without customising it. A template is a starting point, not a finished document. Every participant's supports are different and the agreement should reflect that.
• Not updating agreements when pricing changes. The NDIS Pricing Arrangements are updated at least annually. If your agreement references an old price and you charge a higher current rate, you may be in breach of the agreement.
• Signing before the plan is confirmed. If a participant's plan has not yet been approved or the funding category is unclear, avoid locking in specific support item numbers until you have seen the plan.
• Forgetting to get a signed copy back. Sending an agreement is not the same as having a signed agreement. Follow up and keep the signed copy on file.
• Making the document too long or too legible only to lawyers. A participant who cannot understand their agreement cannot meaningfully consent to it. That is a compliance risk, not just a communication issue.

A realistic example: what goes wrong without a proper agreement

Consider a small provider delivering in-home daily living support to three participants. They have been working with one participant for six months on a verbal arrangement and a rough email exchange. The participant's plan is renewed, the funding drops, and the participant's family disputes the last four weeks of invoices, claiming the rate was never agreed in writing.

The provider cannot produce a signed agreement. The plan manager puts the invoices on hold. The provider spends three weeks in back-and-forth trying to reconstruct what was agreed. Two of those invoices are ultimately written off.

This is not a rare scenario. It happens regularly, and it is almost always preventable with a clear, signed service agreement from the start.

If you are building or improving your provider operations, the provider resources and sign-up information on OpenWay can help you understand what participants and support coordinators are looking for when they evaluate a provider.

Reviewing and updating your agreements

A service agreement is a living document. Review yours at least once a year, or whenever any of the following happen.

1. The NDIS Pricing Arrangements are updated (usually July each year).
2. The participant's plan is reviewed and their funding or goals change.
3. You add new support types or change how you deliver existing ones.
4. There is a change in the participant's circumstances, such as a new decision-maker or a change in living situation.
5. You receive a complaint or dispute that reveals a gap in your current agreement.

When you make a change, both parties should sign an updated version or a written amendment. Do not simply tell a participant verbally that the rate is changing from next month.

Frequently asked

Do unregistered providers need a service agreement?

The NDIS Commission's formal requirement for written service agreements applies to registered providers. However, unregistered providers who work with self-managed or plan-managed participants are strongly advised to use them. A written agreement protects both parties and is considered best practice. Many plan managers will also request one before processing invoices.

Can a participant refuse to sign a service agreement?

A participant can choose not to sign. In that case, you need to decide whether you are comfortable proceeding without one. For most supports, the risk of proceeding without a written agreement falls primarily on the provider. If a participant has capacity concerns or communication needs, work with their support coordinator or nominee to find an accessible format they can engage with.

What happens if there is a dispute about the agreement?

Start with your internal complaints process, which should be described in the agreement itself. If the dispute cannot be resolved, either party can contact the NDIS Commission. For financial disputes involving plan managers, the plan manager may also have a formal dispute process. Keeping detailed records of supports delivered, communications, and signed documents is your best protection in any dispute.

How OpenWay can help

OpenWay is a marketplace where NDIS participants, families, and support coordinators can browse and compare NDIS service providers across Australia. For providers, being listed on OpenWay means your services are visible to participants and coordinators who are actively looking for support.

If you are a provider looking to grow your presence and connect with participants who need what you offer, you can learn more about listing your services on OpenWay. A complete, professional profile, including clear information about your service agreements and how you work, helps participants and coordinators feel confident reaching out.

OpenWay does not deliver supports, handle NDIS plan funds, or make placement decisions. It is a discovery tool, free for participants and families to use.

OpenWay is not part of the NDIS, NDIA or NDIS Commission. Final scope, pricing, travel, cancellation rules and non-face-to-face charges must be confirmed in a written service agreement between the participant (or their authorised support person) and the provider.
