NDIS service agreements: what to include.
An NDIS service agreement is the document that authorises a provider to draw on a participant's plan funds. Without one that is current, signed and on file, you have no billing authority — and it is the first thing an auditor asks for.
This guide covers what a valid agreement must contain, why providers get them wrong, when they expire, how e-signing works under Australian law, and a checklist for getting the process right from day one.
An NDIS service agreement is the written contract that authorises a provider to bill against a participant's plan. It must name each support with its NDIS item code, the price per unit, the funding category, the agreement dates, and a cancellation policy. Without a current, signed agreement on file, you have no authority to claim.
A service agreement is your billing authority
It is tempting to treat the service agreement as paperwork — a form to get signed and filed. It is more than that. The SA is the legal instrument that lets you claim against a participant's plan. Every shift you deliver, every case note you write, every claim you submit rests on it.
Without a current, signed agreement that covers the participant's active plan period, you cannot draw on the plan. It does not matter that the support was genuinely delivered or that the participant is happy with the service — if there is no agreement behind the claim, there is no authority for it. At audit, that gap reads the same as having no documentation at all.
Getting the SA right is not about ticking a compliance box. It is about making sure the money you bill is money you are actually entitled to claim.
What a service agreement must contain
Under the 2021 NDIS Practice Standards, registered providers must have a written service agreement in place for all regulated supports before those supports begin. A document with a signature on it is not enough on its own. A valid SA needs to cover all of the following.
- —The services to be provided, described clearly and matched to their NDIS support item codes
- —The price per unit for each support, at or below the current NDIS Pricing Arrangements limit
- —The funding category each support draws from: Core Supports, Capacity Building or Capital
- —The start and end dates of the agreement
- —The cancellation policy, including what counts as short notice (less than seven clear days) and what you will claim in that situation
- —The participant's right to request a review of the agreement at any time
- —How complaints are handled, and who the participant can contact
The codes and prices matter more than most providers realise. If an auditor asks why you billed a particular support at a particular rate, the answer has to live in the SA. If the agreement does not name the item code and the unit price, there is nothing to point to.
The cancellation clause matters too, for a specific reason: a short-notice cancellation claim is only valid when the agreement contained the cancellation terms upfront. If the participant never agreed to them in writing, the claim has no authority behind it — no matter how clearly the participant cancelled at late notice.
When service agreements expire
A participant's NDIS plan has a fixed end date, typically 12 months from approval. Your service agreement is tied to that plan period. When the plan is reviewed and a new one begins, the old plan ends — and the SA expires with it.
This creates a predictable gap. The plan review happens, the new plan is approved, and in the weeks in between, shifts keep running, case notes keep being submitted and claims keep being generated. If the agreement was not renewed before the old plan expired, those claims sit against an SA that no longer covers the current period.
A lapsed SA is as risky as no SA
At audit, a claim billed after the agreement's end date carries the same risk as a claim with no agreement at all. The billing authority has lapsed. Plan renewals often take longer than expected, and the gap between old-plan end and new-plan approval can run for weeks.
Plan reviews do not run to a perfectly predictable schedule — extensions, delays and early reviews all happen. A coordinator who waits for a plan manager to flag an expired SA is usually too late. Expiry dates need to be tracked proactively, with alerts triggered well before the agreement lapses, not after.
Where providers come unstuck
These are the failure modes that surface at audit, in roughly the order they tend to appear.
Paper SAs in a filing cabinet
Auditors can ask for a signed agreement at short notice. A document that was never scanned, or a folder that has been misplaced, becomes a compliance gap the moment it is under pressure to be produced.
Services listed without codes or prices
An SA that says "community access" without the item code and unit price cannot be validated against the price guide. The claim has no anchor in the written agreement, so there is nothing to justify the rate you billed.
No cancellation policy in the agreement
If the participant never agreed to the cancellation terms in writing, a short-notice cancellation claim has no authority behind it — regardless of how clearly the participant cancelled at late notice.
Unsigned agreements
An SA that was sent but never returned signed, or signed by the provider but not by the participant or their authorised nominee, has no legal standing. A half-signed agreement is, for audit purposes, no agreement.
Expired SA, billing continuing
The plan renewed, the old SA end date passed, and nobody noticed because no system flagged it. Claims kept going out against an agreement that had already lapsed.
Version chaos after amendments
The SA was changed mid-period, but the original was not formally superseded — or the amendment was a verbal change that never made it into a document. At audit, two contradictory versions exist and there is no clear authorised agreement to point to.
Digital service agreements and e-signing
E-signing is legally valid in Australia under the Electronic Transactions Act 1999. A participant, or their authorised nominee, can sign a service agreement on any device. That signature carries the same legal weight as ink on paper, provided the signer had the intention to sign and the capacity to do so.
The practical difference between digital and paper is not the signature itself — it is everything that happens around it. Most providers get this workflow through their NDIS case management software rather than a standalone e-signing tool. A well-designed digital SA workflow does three things automatically.
Generation from the funding setup
Services, NDIS codes and prices are pre-populated from what is already configured for the participant, rather than typed in from scratch each time. The agreement reflects the funding as it has been set up, with no manual re-entry to drift out of sync.
Secure e-signing for the participant or nominee
The participant or their authorised nominee receives a secure, unique link and signs on any device. No printing, no posting, no scanning a returned page and hoping it is legible.
Automatic storage and version control
The signed PDF is retained automatically, tied to the participant record, with a timestamp and a version number. If the SA is amended, the prior version is archived rather than overwritten, so historical claims can always be traced back to the agreement that authorised them.
A paper SA system makes expiry tracking and retrieval entirely dependent on someone remembering. A digital system makes both automatic.
The checklist: what your SA process should do
When you review your current process — or evaluate a practice management platform — look for these things.
- ✓Generate the SA from the participant's funded supports — codes and prices fill in automatically, not typed in by hand each time.
- ✓Include the cancellation policy as a standard clause — so the authority for short-notice claims is always in place before the situation arises.
- ✓Send the SA for e-signing via a secure link — the participant or nominee signs on any device, with no paper copy to chase.
- ✓Store the signed PDF against the participant record — encrypted and timestamped, retrievable immediately by any authorised user.
- ✓Alert coordinators before an SA expires — renewal happens before the agreement lapses, not after billing has run past the end date.
- ✓Create the funding records automatically when the SA is signed — billing is authorised from the moment the agreement is in place.
- ✓Retain all prior versions on file — historical claims can always be traced to the version of the agreement that covered that period.
- ✓Make the full trail visible in one place — signed SA, funded period, delivered shift, case note, billed claim, traceable end to end.
For NDIS providers using practice management software
Rostrel generates a service agreement directly from a participant's funded supports — NDIS item codes, unit prices, and funding categories pre-fill automatically so there is nothing to type in by hand. The participant or their authorised nominee receives a secure link to e-sign on any device, and the signed PDF is stored against their record with an audit timestamp the moment it is complete. Rostrel also tracks each agreement's end date against the participant's plan period and alerts coordinators before it lapses, so billing authority is always renewed before the old SA expires.
Frequently asked questions
What is an NDIS service agreement?
It is the written contract between a provider and a participant (or their authorised nominee) that sets out the supports to be delivered, the NDIS item codes and prices, the funding categories, the agreement dates, and the cancellation and complaints terms. It is also the document that authorises the provider to draw on the participant's plan funds.
Can I bill the NDIS without a signed service agreement?
No. A current, signed agreement is your billing authority. If there is none on file, or it has expired with the plan it was tied to, any claim you make sits against no authority at all. At audit, a claim with no valid SA behind it is one of the most common and most serious findings.
When does an NDIS service agreement expire?
The agreement is tied to the participant's plan period, which usually runs for 12 months from approval. When the plan is reviewed and a new one begins, the old plan ends and the SA expires with it. A new agreement must be in place for the new period before billing continues, so expiry dates need to be tracked proactively rather than discovered after a claim has already gone out.
Is an electronically signed service agreement legally valid in Australia?
Yes. Electronic signatures are valid under the Electronic Transactions Act 1999. A participant or their authorised nominee can sign on any device, and that signature carries the same legal weight as a handwritten one, provided the signer intended to sign and had the capacity to do so.
What must an NDIS service agreement include?
A valid SA should name the supports and match them to their NDIS item codes, state the price per unit at or below the current NDIS price limit, identify the funding category each support draws from, set the start and end dates, include a cancellation policy, note the participant's right to request a review, and explain how complaints are handled and who to contact.
Service agreements done right from day one
In Rostrel, creating a service agreement is the act that authorises billing. The SA modal pre-fills services, NDIS codes and prices from the participant's funding setup, sends a secure link for the participant or nominee to e-sign, stores the signed PDF in encrypted, access-controlled storage, and creates the funding records that authorise billing the moment it is signed.
