Most small businesses need far less than a full-time bookkeeper, but more than the Friday afternoon the owner gives it. The answer depends on four things you can count: bank transactions, bills and invoices, pay runs, and reporting deadlines. This guide shows how to estimate your hours, what part-time hours cost in 2026-27, and when an outsourced finance team is the cheaper way to buy them.
Published: October 2026
Bookkeeping time is driven by volume and complexity, not by revenue. A $10 million business with 50 large invoices a month can need fewer hours than a $2 million cafe with 2,000 card transactions.
The main drivers are:
Our guide to what a bookkeeper actually does each month covers each task in detail.
Count last month's volumes, then put a time against each. Here is an illustrative example for a hypothetical services business with 12 staff paid fortnightly. The minutes per task are planning assumptions for a clean Xero file with bank rules set up, not an industry benchmark, so replace them with your own.
Total: about 26.4 hours a month, or roughly 6 hours a week.
That is less than one day a week. Yet the work cannot all be done in one day, because payroll, super and supplier runs fall on fixed dates. This is why part-time bookkeeping roles often turn into two or three short days spread through the week.
For a quick estimate based on your own volumes, use our bookkeeping cost estimator, or take the do you need a bookkeeper assessment.
Add time for any of these:
Our guide to Payday Super by pay frequency shows how weekly payroll adds to the super workload.
You have three ways to buy the hours.
An employed bookkeeper doing Level 3 or Level 4 work under the Clerks Award must be paid at least $31.11 or $32.67 an hour respectively from the first full pay period on or after 1 July 2026. Casual Level 3 rates are at least $38.89 an hour, including the 25% casual loading. The full rate table is in our Clerks Award reference for 2026-27.
Market rates for experienced bookkeepers sit well above award minimums. Robert Half's 2026 data puts a Sydney bookkeeper at a median base salary of $92,650, which works out to about $46.89 an hour across a 38-hour week. A two-day-a-week role at that rate is about $37,060 a year, or $41,507 with 12% super, before leave cover, software and management time.
Freelancers charge by the hour or by the job, and you pay only for time used. The trade-off is reliability: a sole operator's holidays, illness or full client list become your problem. Our freelance bookkeeper guide covers what to check.
A fixed monthly fee covers the hours, plus the cover, review and systems that a single person cannot provide. Scale Suite packages start from $1,500 per month, and most clients invest $2,500 to $6,000 per month for a complete finance function including payroll, BAS and reporting.

How many hours a week does a small business need a bookkeeper?
It depends on volume. A small services business with a few hundred bank transactions and a fortnightly payroll might need around 6 hours a week, spread across several days. Count your own transactions to estimate yours.
Can a bookkeeper work one day a week?
Some can, but fixed dates for payroll, super and supplier payments often mean the work is better split into short blocks across the week.
How much does a part-time bookkeeper cost in 2026-27?
The Clerks Award minimum for Level 3 work is $31.11 an hour from the first full pay period on or after 1 July 2026. Experienced Sydney bookkeepers are paid well above that, with a Robert Half median of $92,650 a year full-time.
How long does a bank reconciliation take?
With bank rules and clean data, matching a transaction can take a minute or two. Unclear transactions, missing receipts and old unreconciled items take much longer.
Does Payday Super increase bookkeeping hours?
Yes, for many businesses. Super now has to reach each employee's fund within 7 business days of every payday, so there are more payments to make and check than under quarterly super.
Is outsourcing cheaper than a part-time bookkeeper?
Often, once you add super, leave, cover and review. Scale Suite packages start from $1,500 per month, and most clients invest $2,500 to $6,000 per month for a complete finance function including payroll, BAS and reporting.
