Good small business bookkeeping in Perth starts with a separate business bank account, cloud accounting software and a simple weekly routine. Record every sale and expense, reconcile your bank feed, pay super with each pay run and lodge BAS on time. Many owners save time by using online bookkeeping services.

Starting or running a small business in Perth is exciting. But the paperwork can quickly get out of hand. Many owners only look at their books when BAS is due or when their accountant asks for records.

That approach costs money. This guide shows you how to set up simple, reliable bookkeeping that keeps you compliant and helps you grow.

Step 1: Separate Business and Personal Money

Open a dedicated business bank account. It sounds basic, but mixing personal and business spending is one of the most common bookkeeping problems for small businesses. A separate account:

• Makes tracking income and expenses far easier.
• Reduces the time (and cost) of tax preparation.
• Gives you clear records if the ATO asks questions.

Step 2: Choose Cloud Accounting Software

Cloud tools save hours every month. They link to your bank, pull in transactions automatically and help you send invoices and run payroll.

All three support Single Touch Payroll (STP) and BAS preparation. Pick one your bookkeeper and accountant know well.

Step 3: Build a Simple Weekly Routine

A 30-minute weekly habit beats a weekend of panic every quarter. Each week:

1. Reconcile your bank feed so every transaction is matched and coded.
2. Snap and upload receipts using your software’s mobile app.
3. Send invoices and follow up anything overdue.
4. Check upcoming bills and plan your cash flow.

Each month, review your profit and loss report. It shows you what is working and what is not.

Step 4: Get GST and BAS Right

If your business turnover is $75,000 or more, you must register for GST. Then you need to lodge a Business Activity Statement (BAS), usually quarterly.

Common BAS mistakes include:

• Claiming GST credits without a valid tax invoice.
• Using the wrong GST code on purchases with no GST (like bank fees).
• Forgetting to report PAYG withholding for staff.

Good bookkeeping makes BAS a 15-minute review, not a two-day job.

Step 5: Set Up Payroll for Payday Super

If you have employees, 2026 brings a big change. From 1 July 2026, Payday Super rules mean employers must pay super with wages, so it reaches the employee’s fund within 7 business days of payday (Fair Work Ombudsman).

To stay compliant:

• Make sure your payroll software calculates super at the 12% super guarantee rate.
• Pay super every pay run, not once a quarter.
• Keep employee super fund details up to date.
• Reconcile super payments each month.

Step 6: Use the $20,000 Instant Asset Write-Off

Small businesses with turnover under $10 million can immediately deduct eligible assets costing less than $20,000 each. The ATO confirms this has applied from 1 July 2026 and is now permanent (ATO).

To claim it, your books must clearly record each asset’s cost, purchase date and the date it was first used or installed. Clean records make this simple.
