NDIS Plan-Managed vs Self-Managed vs Agency-Managed Billing: What Providers Need to Know

NDIS • BOOKKEEPING

If you provide NDIS supports, one of the most important questions to ask is: how is the participant's plan managed? The answer affects who you invoice, how quickly you get paid, what records you need to keep, and how your business should be set up.

This guide explains the difference between plan-managed, self-managed, and agency-managed funding, and what each one means for invoicing, cash flow, and compliance.

The three funding types

PLAN-MANAGED

A registered plan manager handles the participant's funding. You invoice the plan manager directly and they pay you from the participant's funds.

SELF-MANAGED

The participant or nominee manages the funding. You invoice the participant directly and payment timing can vary.

AGENCY-MANAGED

The NDIA manages the funding directly. Providers claim through the NDIS portal and only registered providers can claim agency-managed supports.

Invoicing differences

PLAN-MANAGED INVOICING

Your invoice goes to the plan manager, not the participant.

• Participant full name
• NDIS number
• Support item number and name
• Date of service
• Unit price
• Quantity
• Total amount

SELF-MANAGED INVOICING

You invoice the participant directly and payment depends on their budget and agreement terms.

AGENCY-MANAGED INVOICING

Claims are submitted through the NDIS portal and must be supported by accurate records.

Cash flow impact

Plan-managed payments are usually faster than self-managed payments, but turnaround depends on the plan manager.

For cash flow forecasting, it helps to separate debtors by funding type. That makes it easier to see where delays are happening and which clients are affecting your working capital.

Comparison at a glance

Area	Plan-managed	Self-managed	Agency-managed
Who you invoice	Plan manager	Participant or nominee	NDIA via portal
Registration required	Not necessarily	Not necessarily	Yes
Price limits	Usually apply	Often negotiable	Strictly apply
Payment speed	Moderate	Variable	Usually predictable

Bookkeeping setup that works

A practical setup looks like this:

Code all NDIS income to one NDIS income account

Track plan managers as separate contacts

Reconcile portal payments monthly

Keep service agreements and delivery notes in your practice management system

Check GST treatment for each service type

Keep audit-ready records for all delivered supports

GST considerations

Most NDIS supports are GST-free, but not all of them are. Apply GST treatment consistently across your business.

Final thoughts

The providers who handle NDIS billing well are the ones who build systems around the way the sector actually works.

If your current setup treats all NDIS billing the same, this is the right time to fix it.
