To have this handled on a fixed monthly fee, see monthly bookkeeping without hourly billing.
A good fixed-price bookkeeping quote should spell out exactly what is included, the volumes it assumes, what happens if those volumes change, and what costs extra. If a quote does not cover reconciliation frequency, payroll, BAS lodgement, reporting and response times in writing, it is not really fixed. This checklist helps you read any quote, including ours, and compare providers fairly. For the broader case for fixed pricing, see our fixed-price bookkeeper Sydney page and fixed-price bookkeeping explained.
Our payroll service sets these out in writing.
See our reporting service and our guide to a useful monthly report.
A fixed price is based on assumptions. Ask for them in writing:
Proper fixed pricing tells you what is not included:
Our published packs are BAS Slayer from $900 a month plus GST, covering monthly reconciliation, quarterly BAS and a monthly profit and loss summary; Payroll Party from $1,500 a month plus GST, adding payroll; and The Lot from $2,200 a month plus GST, adding cash flow snapshots, supplier payment runs and a Xero clean-up. Each has a published range depending on volume or headcount. See our pricing.
Put the quotes side by side against this checklist. A cheaper quote that leaves out payroll, BAS lodgement or reporting is not cheaper once you add those back in. Our guide on hourly vs fixed-fee bookkeepers helps if one quote is hourly.
The review clause. A fixed price that can be increased at any time without notice is not much different from hourly billing. Look for clear volume assumptions and a stated process for reviewing the price.
A provider confident in their pricing will answer each question in writing. Vague answers usually mean the scope is vague too, which is when fixed prices start to drift.
Fixed pricing works best with a short review each year. Compare the agreed volumes with what actually happened, confirm the scope still matches your business, and agree any changes before the new financial year. Tell your bookkeeper early about changes that affect workload, such as new staff, a new bank account or a new sales channel. Small, planned adjustments keep the price fair for both sides and avoid surprises.
Any one of these is worth a question. Several together usually mean the fixed price is a starting figure rather than a firm one. Ask the provider to fix each point in writing before you sign, and compare their answers with this checklist.
Most businesses with regular transactions and payroll suit a fixed fee, because the work is predictable. A business with very irregular activity, such as a seasonal operation that is almost dormant for part of the year, may prefer a lower fixed fee for quiet months with an agreed price for busy ones. One-off projects, such as cleaning up several years of records, are usually quoted as a separate fixed project. The principle is the same each time: agree the scope and the price before the work starts.
Not always on the monthly invoice, but you know the cost in advance and there is no charge for questions. Compare like with like using a written scope.
A good quote explains how and when the price is reviewed. Ask for this in writing.
Usually not. Prior-period clean-ups are normally quoted separately.
For most businesses, yes. Make sure it is lodged by a registered BAS or tax agent.
Tell us your volumes and we will send a written scope and fixed price.
