The short answer: occupational therapy bookkeeping has to reconcile several different funding streams, most commonly NDIS, private health fund rebates and direct private fees, each arriving on a different schedule and needing separate tracking. Add home and community visit travel, which is a genuine cost and claim item rather than an afterthought, and report writing time, which is real clinical work that needs to be billed, not absorbed, and you have the shape of what OT-specific bookkeeping actually covers.

Key takeaways

  • OT income usually splits across NDIS, private health rebates and direct private fees, each needing its own tracking and its own claim rhythm.
  • Home and community visits mean travel time and kilometre claims are a genuine part of an OT's billable and cost picture, not an afterthought.
  • NDIS OT claims sit inside the same 90-day claim window as every other NDIS provider, and OT-specific line items and price limits change the detail.
  • Report writing time is real, billable clinical work, and practices that don't track it are giving it away for free.

Three Funding Streams, One Practice

Most Mornington Peninsula OT practices see a mix of NDIS-funded participants, private clients claiming a health fund rebate, and clients paying privately with no third-party funding at all. Each of these needs to be tracked separately in the books, because each has different claim timing, different documentation requirements, and different GST treatment. Blending them into a single "fees received" line makes it impossible to see which funding source is actually driving the practice's growth, or its cash flow gaps.

NDIS Claims: The 90-Day Window Still Applies

Occupational therapy delivered under an NDIS plan is claimed against specific line items within the current pricing arrangements, and agency-managed claims still need to be lodged within 90 days of the service booking ending. The OT-specific detail is in the line items themselves, assessments, therapy, home modifications assessments and reports each sit under their own code and price limit, so a claim coded generically rather than against the correct item risks rejection.

Travel: A Real Cost and a Real Claim

Home and community visits are core to OT practice, and the travel involved is neither free to the practice nor invisible to funding bodies. NDIS travel claims have their own rules around how much can be charged and under what circumstances, and internally, tracking actual travel time and kilometres against what's being claimed is the only way to know whether a home visit is actually profitable once travel is accounted for.

Report Writing Is Billable Work, Not Overhead

Assessment reports, NDIS plan reports and home modification recommendations take real clinical time to write, often as much as the session that prompted them. Practices that don't separately track and bill this time are effectively donating hours every week. Time recording that captures report writing as its own billable category is one of the simplest changes that improves an OT practice's real margin without seeing a single extra client.

ReportWhat it tells a practice owner
Revenue by funding streamWhether NDIS, health fund or private fees are driving growth
Claims lodged vs claims paidGaps between delivered and claimed NDIS work
Travel cost vs travel claimedWhether home visits are genuinely profitable
Billable hours vs report-writing hoursWhether clinical time is being captured or given away

Utilisation for a Practice That Travels

Utilisation, delivered hours against available hours, matters just as much for OT as it does for any allied health practice, but home and community visit travel time genuinely eats into a clinician's available capacity in a way a clinic-based practice never experiences. A practitioner who looks fully booked on the calendar may actually be delivering far fewer billable hours once travel between visits is accounted for. Tracking utilisation net of travel, rather than gross calendar bookings, is what tells a growing practice whether it genuinely needs another OT, or whether tightening the visit schedule and grouping nearby appointments would free up the same capacity without a new hire.

What to Ask Before You Hire

  • "Have you reconciled NDIS OT claims against the current pricing arrangements before?"
  • "How do you track home visit travel against what's claimed?"
  • "Is report writing time captured separately in your billing setup?"
  • "Are you a registered BAS agent?" Verify at tpb.gov.au.

Equipment and Home Modification Assessments

OT practices doing home modification and equipment assessment work often coordinate with suppliers and installers, sometimes handling quotes and invoices on a client's behalf as part of the service. This creates a genuine bookkeeping question: money moving through the practice for equipment that isn't the practice's own revenue needs to be tracked separately from clinical fee income, similar in spirit to how disbursements work in a legal or conveyancing practice. Blending the two makes both the practice's real revenue and its GST position harder to see clearly, and it also makes it harder to prove to a funding body exactly what the practice charged for its own service versus what was simply passed through on the client's behalf.

Group Practices and Multiple Clinicians

As an OT practice grows past a solo operator to include associate OTs or allied health assistants, payroll and revenue-per-clinician reporting become genuinely important rather than optional extras. A practice owner who can see each clinician's revenue, claim success rate and utilisation separately is running the business on real information. One who only sees the combined total is making hiring and caseload decisions on a guess, no matter how well-intentioned that guess is, and guesses are an expensive way to grow a small practice.

What This Typically Costs

Fixed monthly bookkeeping for a Mornington Peninsula OT practice generally sits between $350 and $900, depending on caseload size, the mix of NDIS versus private work, and whether the practice runs additional clinicians. As with any allied health practice, the figure is quoted after a free look at your file, since NDIS-heavy caseloads with high claim volumes genuinely take more reconciliation time than a mostly private-fee practice of the same size.

The Bottom Line

OT bookkeeping done properly keeps three funding streams honestly separated, treats travel as a real number instead of a shrug, and makes sure report writing gets billed like the clinical work it is. None of that requires seeing more clients, it requires books built to show what's already happening.
