The real problem with receipts
Most trade businesses do not lose money because one receipt goes missing. The bigger issue is that expenses become hard to explain later. A fuel receipt, tool purchase, material order, parking fee, or subcontractor bill is much more useful when it is recorded with the date, supplier, amount, category, and job reference.
If you wait until the end of the quarter or year, the transaction may still exist in your bank feed, but the context is often gone. Was it for a specific customer job? Was it partly private? Was it materials, tools, repairs, or vehicle running cost? Those details matter.
Capture the important fields
- Supplier name, transaction date, total amount, and GST amount when applicable.
- Receipt image, PDF, or tax invoice copy.
- Expense category such as materials, fuel, tools, subcontractors, equipment hire, insurance, software, phone, or vehicle costs.
- Job or customer reference when the cost belongs to a specific project.
- Short notes for unusual purchases or split business/private use.
Use categories consistently
A short category list is usually better than a complicated one that nobody uses consistently. Choose categories that match how you review the business: direct job materials, tools, vehicle, subcontractors, insurance, software, office, advertising, phone, and professional fees are common starting points.
Review categories monthly. Fixing ten transactions while you remember them is easier than fixing hundreds later.
Keep records long enough
Australian businesses generally need to keep records for several years, and the ATO has detailed guidance about record-keeping obligations. Make sure digital records are backed up and readable, not trapped in a personal phone gallery or a single email inbox.

Monthly routine
- Upload receipt images for cash and card purchases.
- Match large expenses to jobs or customers.
- Check supplier invoices against bank payments.
- Export or review a monthly expense summary.
- Ask your accountant about anything you are unsure how to classify.
Separate job costs from business overheads
It is useful to know the difference between costs that belong to a specific job and costs that keep the business running. Materials, equipment hire, and subcontractor invoices often belong to one job. Insurance, phone, software, registration, and general tools may be overheads.
That distinction helps you quote future work more accurately. If a job looks profitable until materials, hire, or subcontractor costs are added, the quote structure may need to change.
Watch for private-use expenses
Some expenses may have both business and private use, such as phones, vehicles, internet, or tools used outside the business. Do not guess at the end of the year. Keep notes while the details are fresh and ask your accountant how they want those records shown.
Tradie Biller supports this habit by keeping expenses alongside invoices, quotes, and clients, so day-to-day records are easier to find when you need them.
