Bookkeeping for Dental Practices in Melbourne

What Makes Dental Practice Bookkeeping Different

A busy Melbourne dental practice can have five revenue streams, three payment channels, two types of practitioner arrangements and a cost structure that includes significant lab fees — all running simultaneously. A generalist bookkeeper typically sets up a single income account, codes everything in, and produces a P&L that tells the practice owner almost nothing useful about where money is actually coming from or which parts of the practice are most profitable. Getting the structure right from the start makes every business decision — scheduling, pricing, hiring — possible to make on real data rather than guesswork.

Revenue Streams: Clinical, Cosmetic and the GST Boundary

Most clinical dental services — examinations, fillings, extractions, root canals, orthodontics for medical reasons — are GST-free under the health services exemption in the GST Act. Purely cosmetic procedures are not. Teeth whitening and aesthetic-only veneers sit clearly in taxable territory. Some procedures — implants, complex cosmetic work that also has a clinical component — require judgement about the primary purpose of the treatment.

For a Melbourne practice offering a mix of clinical and cosmetic services, income needs to be tracked by treatment type so the BAS correctly identifies what is and isn't subject to GST. A practice that applies GST-free treatment to all dental income is understating its GST liability on cosmetic work. A practice that applies GST to everything is overcharging patients on clinical services and paying too much to the ATO. Neither is a small error at the volumes a busy practice operates.

HICAPS and Private Health Fund Reconciliation

HICAPS is the system that processes private health fund rebates at the point of service. When a patient presents their health fund card, HICAPS checks their cover and processes the rebate in real time. The patient pays the gap, and the fund settles the rebate amount to the practice in a batch payment — usually daily or every few days, but not immediately and not in amounts that match individual appointment invoices.

This creates a structural reconciliation challenge. A single day of patient appointments generates gaps paid in cash or card on the day plus multiple HICAPS batch settlements arriving over the following days from different funds (Medibank, Bupa, HCF, NIB and others all run their own settlement cycles). Matching these settlements to the underlying appointments requires systematic reconciliation — not just matching the bank deposit to "today's income" — or the practice ends up with a growing list of unreconciled transactions that distort the P&L and inflate apparent debtors.

Associate Dentists: Contractor or Employee?

The most common arrangement for associate dentists in Melbourne practices is a contractor agreement — a percentage of billings, ABN invoicing, no leave or super entitlements. This arrangement is administratively convenient, but it creates serious compliance risk when the underlying relationship doesn't satisfy the legal contractor definition.

Following the 2024 High Court decisions on worker classification and the ATO's updated guidance, an associate who works defined days at the practice, uses the practice's equipment and chair, sees patients booked through the practice's systems, cannot work for other practices during those hours, and has no real ability to subcontract their work is very likely an employee. The fact that both parties signed a contractor agreement doesn't change this classification.

The consequences of getting this wrong are substantial: back-payment of superannuation under the Superannuation Guarantee Charge (with 10% interest and administration fees), unpaid PAYG withholding obligations, and potential exposure under the Fair Work Act. A bookkeeper who correctly identifies the nature of associate arrangements — not just processes the invoices — can flag this risk before it becomes a liability.

Lab Fees as Cost of Goods

Dental laboratories charge the practice for crowns, bridges, dentures, veneers, aligners and other prosthetic work. These fees are a direct cost of delivering specific treatments — they don't exist unless the treatment was performed, and their cost directly affects the margin on that treatment. Recording them as general operating expenses conflates them with rent, power and administrative costs, making it impossible to understand what each treatment type actually costs the practice to deliver.

In a correctly structured Xero setup for a dental practice, lab fees are recorded as cost of goods sold against the treatment category they relate to. This allows the practice to see — at a glance — the gross margin on crown and bridge work versus simple restorative versus orthodontic, which is the information needed to make intelligent decisions about which services to promote and which to price differently.

Equipment: Depreciation and the Instant Asset Write-Off

Dental equipment — chairs, digital X-ray units, CBCT scanners, CAD/CAM mills — is expensive and long-lived. The depreciation treatment for these assets affects the P&L significantly in the year of purchase and in subsequent years. The instant asset write-off threshold (which has varied significantly in recent Federal Budgets) may allow immediate deduction for some equipment purchases, while others must be depreciated over their effective life. A bookkeeper needs to apply the correct treatment for each asset and track the asset register accurately so depreciation is calculated correctly each year.
