Self-managed vs plan-managed vs agency-managed: who do you invoice, and how you get paid

Who you invoice depends on how that part of the participant's NDIS plan is managed. A self-managed participant pays you themselves, so the invoice goes to them. A plan-managed participant has a plan manager who receives your invoice and pays you from the plan. An agency-managed (NDIA-managed) participant has no invoice at all on the provider side: a registered provider lodges a payment request in the NDIA's own portal and the NDIA pays. The service agreement should name the payer before the first visit, and the invoice goes to whoever it names.

The three arrangements are the NDIA's own, set out in its guide to management options. One plan can mix them: core supports self-managed and capital supports NDIA-managed, for example. So the question is never "how is this participant managed" but "how is the funding for this support managed".

What do the three management types actually mean?

The NDIA describes each one in terms of who pays providers and who keeps the financial records.

Self-managed. The participant, their nominee or their representative pays providers and keeps the records themselves. The NDIA calls this the option with the most flexibility, and it is the one where you are dealing with a person rather than an organisation.

Plan-managed. A registered plan manager holds the funding, pays providers and keeps the records. The participant's plan carries separate funding to pay for the plan manager, so it costs the participant nothing out of their support budget. The plan manager is a business, and to you it behaves like one: it has an invoices inbox, a checklist, and a turnaround time.

NDIA-managed. The NDIA itself pays providers and keeps the records. The NDIA's guide notes that this is "sometimes called Agency-managed", which is why you see both names in the same conversation.

Who holds the money, and who pays you?

This is the practical heart of it, and the NDIA's guide to getting paid spells out the provider's side of each arrangement.

	Self-managed	Plan-managed	Agency-managed (NDIA-managed)
Who holds the money	The participant draws it from the plan	The plan manager, from the plan	The NDIA
Who you send the invoice to	The participant (or nominee)	The plan manager	Nobody. You lodge a payment request in the NDIA's provider portal
Who pays you	The participant	The plan manager	The NDIA
Must you be a registered provider?	No	No	Yes
Typical timing	When the participant pays. They then claim from their plan	Ask the plan manager. NDSP, for example, publishes three to five days for most payments	Valid claims are usually paid in two to three business days, or around ten if the NDIA needs to check the claim

Two things in the table deserve a closer look.

The registration rule is the NDIS Commission's, not the NDIA's. Its registration page lists the supports that require registration, and one of them is any support to a participant with NDIA-managed funding. Unregistered providers can work with everyone else: in the Commission's words, only participants who self-manage or plan-manage can choose unregistered providers. If you are weighing up whether to register, registered vs unregistered walks through the trade.

The NDIA's payment terms apply to the NDIA's own claims. Its guide says valid claims are usually paid within two to three business days, and can take about ten business days if you are not recorded as a "my provider" on the participant's plan or the claim needs checking. Those numbers describe the NDIA's own processing; they say nothing about how quickly a plan manager or a self-managed participant pays you.

What does each payer need on the invoice?

The content of an NDIS invoice is mostly the same whoever receives it, and the full list with a checklist is in what an NDIS invoice must include. The differences are in emphasis.

• A self-managed participant needs enough detail to make a claim in the participant portal: the dates the support began and ended, the support category, the amount, your name and ABN, and a description. Once they have paid you, the NDIA asks you to send a receipt so they can acquit the expense against their plan.
• A plan manager needs everything a self-managed participant needs, plus the support item number, because the plan manager enters your invoice into the provider portal on your behalf. The NDIA's guide is specific that the invoice must carry a valid ABN unless you are exempt. Most plan managers publish their own checklist as well.
• The NDIA does not receive an invoice. A payment request needs the participant's name and NDIS number, the dates of support, the support item reference number and the price. The NDIA also asks for the request within 90 days of the end of a service booking, and never later than two years after the support was delivered.

What happens when a participant changes management type?

A participant can ask to change how their plan is managed at any time. The NDIA's guide says they do not have to wait for a new plan, and that the current plan is updated if the NDIA agrees. You usually hear about it from the participant, from a plan manager, or when an invoice comes back unpaid.

Nothing in the rules tells you retrospectively to re-invoice work already paid. What changes is where the next invoice goes. So when you hear of a change, check three things: the date it took effect, who is paying from that date, and whether any visits already delivered but not yet invoiced fall on the new side of the line. Then update the service agreement, because the agreement is where the payer is written down.

The one change that needs more than an email is a move to NDIA-managed funding. If you are not a registered provider, you cannot claim for that support, and the participant needs to know that before the change goes through, not after.

What does the workflow look like for a sole trader?

Strip away the vocabulary and the routine is short.

1. The service agreement names the payer. Before the first visit, write down whether the support is self-managed, plan-managed or NDIA-managed, and who the payer is: the participant's own details, the plan manager's business name and invoices email, or the NDIA. If one plan mixes management types, name the payer per support, not per participant.
2. The invoice goes to the payer the agreement names. Not to whoever is easiest to reach. A plan-managed invoice sent to the participant sits in a drawer; a self-managed invoice sent to a plan manager gets bounced.
3. The participant gets a copy. Even when the plan manager pays, the participant is the customer. Copying them in is good manners, and several plan managers ask for it so the participant can approve the invoice.

The idea underneath all of this is that the person who receives the care and the organisation that pays for it are two different records. The participant is always the client; the payer, the "bill-to", may be the participant, a plan manager, or another funder. Keeping the two apart is what lets you change the payer without touching anything about the client.

How HarvestFlow Care handles who pays

HarvestFlow Care keeps the client and the payer separate in exactly this way. A client is a person record. A payer is an account: an organisation, an individual, or in the Care edition a plan manager account, which carries its own billing email so invoices go straight to the plan manager's inbox rather than to the participant's home address.

The link between them is the service agreement. Each agreement records the funding source, the dates, the funded items and rates, and a bill-to account: the plan manager, the participant themselves, or another funder. When you raise an invoice from delivered visits, the payer is resolved from the agreement's bill-to account first, then from the client's own account, and finally as a private payer. The invoice is addressed to that payer, and the invoice list shows the payer and the client side by side, collapsing to one name when a self-managed participant is paying for themselves. A plan manager that pays for several of your clients can be marked for consolidated billing, so it receives one combined invoice instead of one per client.

When a participant switches management type, you edit the agreement's bill-to account and the next invoice goes to the new payer. The visits already invoiced are stamped with what billed them, so nothing is invoiced twice.

What HarvestFlow Care does not do: claim from the NDIA. For an agency-managed participant, lodging the payment request in the NDIA's provider portal is the registered provider's own act, with the provider's own credentials, and HarvestFlow Care does not do it on your behalf. It records the visits, prepares the figures and the export, and hands them to you. It is also why the price is a flat monthly amount rather than a cut of what you claim; see pricing and why we do not take a percentage. If you want to see the agreement and bill-to flow before you set anything up, the quick start guide walks through it with a first client.
