Ask any small business owner who's used an hourly bookkeeper and you'll hear some version of the same story. The invoice was fine for a few months, then a quarter with more transactions, a staff change, or BAS time came along, and suddenly the bill was noticeably higher, with no warning.
Fixed price bookkeeping solves that by removing the variable entirely. You agree on a scope upfront, pay one monthly fee, and that fee doesn't move regardless of how busy the month gets. It's the same shift that's already happened in software, insurance, and most other business expenses. Bookkeeping is just catching up.
Here's exactly how it works, what it costs compared to hourly, and how to tell if it's the right model for your business.
The problem
How hourly bookkeeping actually costs you
Traditional bookkeepers in Australia typically charge $50 to $120 per hour, depending on experience and location. That structure creates a few predictable problems:
- Your invoice is a moving target. Budgeting for "bookkeeping" becomes budgeting for a range, not a number.
- Busy months cost more, right when cash flow is already tightest. A new hire, EOFY, or a spike in transactions all drive the bill up at the worst possible time.
- There's a built-in disincentive to ask questions. Every email or clarification is technically billable time, so business owners often just don't ask.
- You're paying for the bookkeeper's time, not for an outcome. Slower reconciliation and more back-and-forth mean more hours, and even with good intentions, the incentives aren't aligned with speed or clarity.
None of this makes hourly bookkeepers bad at their job. It just means the pricing model works against predictability, which is usually the thing small business owners want most from their finance function.
The alternative
How fixed price bookkeeping works
With a fixed-fee model, the structure flips:
- You choose a plan with a defined scope: what's reconciled, what's reported, how often, and by when.
- You pay that amount every month, regardless of transaction volume within the plan's scope.
- If your needs grow, you either add a defined add-on (BAS, payroll, catch-up) or move to a higher tier. Both come with their own fixed price, agreed before you commit.
At advancr, that looks like three plans:
| Plan | Monthly fee | Scope |
|---|---|---|
| Core | $249/mo | Ongoing bookkeeping, reconciliation, and compliance-ready records |
| Momentum | $449/mo | Everything in Core, plus a monthly financial summary and cash position visibility |
| Velocity | $749/mo | Everything in Momentum, plus forward-looking financial awareness and a quarterly review |
Add-ons follow the same logic. BAS Preparation & Lodgement is $140/quarter or $70/month, Payroll Processing starts at $150/month, and Catch-Up Bookkeeping is $249 per month of catch-up required. Every number is fixed before you agree to it. Nothing is billed retrospectively based on hours worked.
Side by side
Fixed price vs hourly: a direct comparison
| Hourly bookkeeping | Fixed price bookkeeping | |
|---|---|---|
| Monthly cost | Variable, depends on hours worked | Fixed, agreed upfront, same every month |
| Busy months | Cost more | Cost the same |
| Asking questions | Often billable | Included in the plan |
| Budgeting | Estimate a range | Know the exact number |
| Scope creep | Invoice grows quietly | Requires an explicit plan change or add-on |
| What you're paying for | Time spent | A defined outcome, delivered on a schedule |
The honest caveat: if your bookkeeping needs are extremely minimal and irregular, say a handful of transactions a few times a year, a low hourly bill might occasionally come in under a fixed monthly fee. But for any business with ongoing, regular transaction volume, predictability tends to win on both cost and stress, because the fixed fee accounts for your actual usage pattern rather than penalising the months you're busiest.
Beyond the invoice
A side benefit: your books are always ready when you need them
Fixed price bookkeeping isn't just about the invoice. It's also about what the structured, done-every-month workflow leaves you with.
Because reconciliation and record-keeping happen on a fixed monthly rhythm rather than getting picked up whenever there's budget for an hourly bookkeeper, your books stay current and accountant-ready by default. That matters most at the exact moments it's hardest to fix retroactively: a bank or lender asking for up-to-date management accounts as part of a loan application, a landlord or supplier requesting financials before extending trade credit, or an accountant needing clean numbers ahead of a deadline.
With hourly, ad-hoc bookkeeping, these requests often mean scrambling to catch up months of records first, sometimes at a rush rate. With a fixed monthly plan, the records already exist. There's no catch-up bookkeeping fee and no delay while someone reconstructs the last two quarters. Your books are simply ready, because keeping them that way was already part of what you were paying for.
Behind on your books already? Catch-up bookkeeping is priced the same way: a fixed $249 per month of catch-up required, added to your first payment, so there's no rush-rate surprise there either.
Before you switch
What to check before switching to a fixed-price provider
Not all "fixed price" offers are equal. Before signing up, confirm:
- What's actually included. A fixed price with a vague scope can still turn into scope-creep negotiations later. Look for a plan that spells out reconciliation frequency, reporting, and turnaround times, not just a dollar figure.
- What triggers an upgrade. You want to know upfront what happens if your transaction volume grows, not find out via a surprise invoice.
- Whether add-ons are also fixed price. BAS, payroll, and catch-up bookkeeping should have their own clear, fixed cost, not revert to hourly billing once you need something beyond the base plan.
- Software compatibility. Make sure the provider works natively with your platform (Xero, MYOB, QuickBooks) rather than requiring a migration.
Is it for you
Is fixed price bookkeeping right for your business?
If you're a sole trader, small business, or growing company that wants to know exactly what you're paying each month, and wants that number to reflect what you're actually receiving rather than how long it took someone to do it, fixed price bookkeeping is built for you. It removes the anxiety of an unpredictable invoice and replaces it with a plan you chose deliberately, while keeping your books ready for whatever comes next.
