In a group program one worker supports several participants at once, and each participant is billed at the ratio that applied to them. Getting that wrong in either direction is either lost revenue or a claim you cannot defend.
Group services sil — how it works
A group shift has one worker and several participants attached. Rostery bills each participant at the support ratio that applied — 1:2, 1:3 and so on — using the catalogue item for that ratio, so a shift with three participants produces three correct claims rather than one divided by three.
The same mechanism covers SIL houses, where the ratio varies through the day and overnight arrangements differ from daytime. Because the shift knows its participants and its ratio, both the claim and the roster record reflect what actually happened.
Why it matters for NDIS providers
Group billing done manually is where providers most often under-claim, because working out the correct ratio item for each participant on each shift is tedious enough that a simpler approximation gets used instead.
- Ratio-correct claiming: each participant billed at the catalogue item for the ratio that applied.
- One shift, many participants: the roster reflects how the work was actually delivered.
- Covers SIL and day programs: the same model handles both.
What's included
- Group shifts. One worker, several participants, on a single shift record.
- Ratio-based billing. The correct catalogue item per participant for the applicable ratio.
- SIL rostering. House-based shifts including overnight and active-support arrangements.
- Per-participant records. Notes and attendance recorded per participant on the shift.
- Facility linkage. Group shifts attached to the site they were worked at.
Who it's for
Providers running SIL houses, day programs, group community access or centre-based supports. The larger the group, the more the ratio arithmetic matters — and the more likely it is currently being approximated.
Getting started
Group Services & SIL is included in your Rostery plan and works the moment your data is in — there is no separate module to buy or set up. Book a demo and we will show it on your own workflows, and use Rostery's “Smart Switch” data migration to bring your existing clients, staff, shifts and notes across from your current software in minutes.
