Bookkeeping for Mandurah’s mix of small businesses

Mandurah has a real mix of small businesses. Based on ABS business counts published by economy.id, the city had 5,199 registered businesses in 2025. Construction was the largest group, with 1,247 businesses, or 24.0%. Health care, professional services, real estate and transport businesses were also common.

Each type of business needs something a little different from its books. For example:

• Cafes and food businesses juggle daily takings, supplier bills, casual staff and award rates.
• Retailers and online sellers need stock, card payments and marketplace fees reconciled properly.
• Salons and health practitioners often manage bookings, contractors and payroll at the same time.
• Consultants and sole traders want simple, tidy records and a clear view of GST.
• Landlords need rental income and expenses tracked for each property.
• Tradies need job costs, materials and subbie payments recorded correctly.

So we don’t use a one-size-fits-all approach. Instead, we set up your bookkeeping around how your Mandurah business actually runs.

BAS and GST deadlines for Mandurah businesses

Most small businesses lodge BAS quarterly. According to the ATO, the quarterly BAS due dates are 28 October, 28 February, 28 April and 28 July. Monthly BAS is generally due on the 21st of the following month. In addition, a registered tax or BAS agent may be able to give you extra time.

GST is another common question. The ATO says you must register for GST once your GST turnover reaches $75,000 or more. Taxi and rideshare drivers must register regardless of turnover. Good bookkeeping helps you see that threshold coming, rather than finding out too late.

Record keeping and local rules

Clean records also make life easier with the ATO. The ATO says most business records must be kept for 5 years. Therefore, we keep your receipts, invoices and bank records organised in your software, ready when you need them.

Mandurah businesses may also have council costs to track, such as licences, permits or rates. We can record renewals like these in your books, so they don’t surprise you. For a snapshot of the local population, see the ABS 2021 Census QuickStats for Mandurah.

Common situations we help with

Tradies and building businesses. Construction is the biggest business group in Mandurah. We record job costs, materials and subcontractor payments. If you pay contractors for building and construction work, your records also need to support the ATO’s taxable payments annual report.

Employers. We set up payroll and Single Touch Payroll reporting. The ATO’s Payday Super page explains how super guarantee is paid with each pay run from 1 July 2026, and we can help you make the change.

Business owners with property or investments. We keep business and private spending separate and can track income and expenses for each rental property.
