Your practice sees 400 patients a week, bulk bills half of them, splits fees with six doctors, and runs a nursing and admin payroll that never sleeps. Barry, meanwhile, has coded three months of Medicare batch payments to "miscellaneous income" and calls the clearing account "the mystery bucket". Mate, that's not bookkeeping, that's malpractice with a spreadsheet. Medical practices have some of the most distinctive books in Sydney small business, and most of the horror files we open were done by someone who treated a clinic like a cafe with stethoscopes. Here's what a medical practice bookkeeper actually has to handle.

What Makes Medical Practice Books Different

Three structural things, and they compound.

Money arrives in batches, not transactions. Private fees through the terminal, Medicare bulk-bill batches, health fund payments, DVA claims, all landing as lump deposits that have to reconcile back to individual consults in the practice software. Done right, a clearing account matches every batch to its claims weekly and sits at zero. Done Barry-style, the clearing account grows like a tumour and nobody can say which doctor earned what. Weekly reconciliation of the batch flows is the core of proper monthly bookkeeping for a practice, and it is non-negotiable, because every other number in the clinic depends on it.

The practice usually isn't the doctors. Most Sydney clinics run a service arrangement: the practice entity provides rooms, staff, and admin, collects the fees, and pays each practitioner their percentage, or charges them a service fee. That means two sets of books talking to each other, doctor payment calculations that must be right to the dollar every cycle, and paperwork behind the arrangement that matters enormously (more on that below). A bookkeeper who doesn't understand the split ends up with revenue that belongs to doctors sitting in the practice's P&L, which flatters the numbers right up until it wrecks them.

GST goes both ways at once. Patient consultations are generally GST-free. The service fees the practice charges its doctors are generally taxable. A clinic therefore runs GST-free income and taxable income through the same file, claims input credits on a mixed basis, and produces a BAS with more moving parts than almost any business its size. We have seen practices paying GST on income that never should have carried it, and practices not charging it where they must. Both are fixable; neither is optional. BAS for a clinic belongs with a registered agent who lodges it properly, full stop.

The Payroll Tax Issue Every Practice Owner Has Heard About

You've read the headlines: state revenue offices have been treating payments to contractor doctors under some service arrangements as wages for payroll tax, and several states have since introduced exemptions or rebates, some tied to bulk-billing levels. The rules differ by state, they turn on the exact wording and operation of your agreements and payment flows, and they are moving. We are not going to pretend a blog post settles it, and you should treat anyone who does with suspicion.

What the bookkeeping side must do, regardless: keep the doctor payment flows clean, consistent, and matching the written agreements, so that whatever position your tax advisor takes, the records actually support it. Payment flows that drift from the paperwork are how practices lose these arguments. Get the structure advice from your accountant or lawyer; get the flows recorded properly every single week from your bookkeeper. Both, not either.

Payroll for the People Who Actually Run the Place

Nurses, receptionists, practice managers: award-covered, often part-time, often across split shifts, and since 1 July 2026 their super has to land in their funds within 7 business days of every payday under the new Payday Super rules. A clinic on weekly or fortnightly pays now generates a super deadline almost constantly, and the redesigned penalty regime notices automatically. Add the usual clinic patterns, leave loading, weekend rates, allowances, and payroll becomes the second place a generalist quietly drowns. It's the second thing we check on every new practice file, right after the mystery bucket.

A Worked Example: The Clinic That Thought It Made $310K

A hypothetical, assembled from the usual pattern. A $2.8M three-doctor practice in Sydney's north, from Macquarie Street specialists down to suburban GP clinics around Chatswood, the shape repeats. On paper: $310K profit. In the file: $146,000 sitting in a clearing account nobody had reconciled in seven months, doctor percentages calculated off gross deposits instead of net batch amounts (two doctors overpaid, one underpaid, all three now grumpy), GST charged on precisely nothing including the service fees where it belonged, and a receptionist's super running a fortnight behind the new deadline since day one of July.

None of that was fraud. It was a clinic-shaped business with a cafe-shaped bookkeeper. The cleanup ran as a fixed-price catch-up job, the doctor splits were rebuilt off reconciled batches, and the real profit figure turned out to be a different number, which is the entire point: you cannot run a practice on numbers that include other people's money.

What a Medical Practice Bookkeeper Should Cost in Sydney

Fixed monthly, scoped on batch volume, number of practitioners, payroll headcount and frequency, and the state of the file on arrival. Not hourly, because batch reconciliation is exactly the kind of work an $80-to-$150-an-hour operator can graze on indefinitely, and you will never be able to tell four hours from nine. The quote should name the scope line by line: weekly batch and clearing reconciliation, doctor payment calculations, payroll with payday-timed super, BAS through a registered agent (check the registration yourself on the Tax Practitioners Board register), and month-end reports that split practice income from doctor flows. If any of those are "extra", the headline price is fiction. Allied health group with a similar shape? The allied health bookkeeper guide covers your version. We've got you either way.

FAQ

What does a medical practice bookkeeper do that a normal bookkeeper doesn't?

Weekly reconciliation of Medicare, health fund, and DVA batches through a clearing account, doctor service-fee and percentage calculations, the GST-free versus taxable income split, and award payroll with payday-timed super. A generalist reconciles the bank; a practice bookkeeper reconciles the batches behind it.

How should Medicare payments be recorded in Xero?

As batch deposits matched through a clearing account back to the individual claims in the practice software, reconciled weekly so the clearing account returns to zero. A growing clearing balance means the practice's income figures are guesses.

Are GP consultations GST-free?

Most medical services are GST-free, but the service fees a practice charges its practitioners are generally taxable, so a clinic runs both treatments through one file. The split needs to be set up correctly and reflected properly in every BAS.

What is the payroll tax issue with contractor doctors?

State revenue offices have treated some contractor-doctor arrangements as wages for payroll tax, and several states have introduced exemptions or rebates with conditions. It is state-specific, fact-specific, and changing, so take structure advice from your accountant or lawyer, and make sure the bookkeeping matches the agreements exactly.

How does Payday Super affect medical practices?

From 1 July 2026, super for your nurses, reception, and admin staff must reach their funds within 7 business days of each payday. Weekly and fortnightly clinic payrolls now carry near-constant super deadlines, so payroll process discipline matters more than ever.

How much does a medical practice bookkeeper cost in Sydney?

Fixed monthly, scoped on batch volume, practitioner count, and payroll size. Avoid hourly billing on practice files; batch reconciliation is the worst possible place for an open meter.

Can you fix a practice file with months of unreconciled batches?

Yes, as a fixed-price catch-up: batches matched to claims, the clearing account cleared, doctor splits recalculated off reconciled figures, and GST corrected properly through a registered agent where lodgements were wrong.

Do you work with specialists and allied health as well as GPs?

Yes. Specialist rooms, GP clinics, and multi-practitioner allied health groups share the same batch-and-split structure; the mix of payers changes, the bookkeeping discipline doesn't.
