OLD INVOICES? DON’T LEAVE THEM SITTING. ⏰
If you’ve got old invoices sitting in your system waiting to be sent, now is a very good time to get them sorted.
From 1 December 2026, NDIS claims must be submitted within 90 days of the support being delivered.
That means the date that matters is the date the support was actually delivered — not the date you eventually create the invoice or send it to your Plan Manager.
And there’s another reason not to leave invoices sitting around.
The NDIA is already applying additional integrity checks to older claims. Since July 2026, claims submitted 6 months or more after a support was delivered may be held for additional review, which can take up to 28 days.
So our message to providers is pretty simple:
• check your accounts for any outstanding NDIS invoices
• make sure all supports already delivered have been invoiced
• check that dates, support items, rates and participant details are correct
• send invoices promptly rather than allowing them to accumulate
• if we query something, respond as soon as possible so we can keep the claim moving.
And please don’t treat 90 days as the new invoicing schedule. 😂
It’s a deadline — not a target.
Regular, timely invoicing makes it easier for providers, participants and Plan Managers to identify issues while the information is still current.
December will be here before we know it.
Get the old ones sorted. Keep the new ones current. And don’t wait until day 89. 😉
