Bookkeeping often feels like a chore for builders and tradies, but it plays a crucial role in keeping your business healthy and growing. Without clear financial records, you risk missing out on profits, paying unnecessary taxes, or struggling to manage cash flow. This post shares practical bookkeeping tips tailored for builders and tradies, helping you stay organised, save money, and make smarter business decisions.

Keep Your Receipts and Invoices in Order
One of the biggest bookkeeping challenges for builders and tradies is managing receipts and invoices. You handle many small purchases daily, from materials to tools, and every job generates invoices. Losing track of these documents can cause errors in your accounts and tax returns.
Use a dedicated folder or digital app to store receipts immediately.
Label invoices by job or client to simplify tracking payments.
Take photos of paper receipts if you prefer digital records.
Regularly update your records, ideally weekly, to avoid backlog.
For example, a tradie who uses a mobile app to scan receipts on-site saves hours of sorting paper later. This habit also helps when claiming expenses during tax time.
Separate Business and Personal Finances
Mixing personal and business finances is a common mistake that complicates bookkeeping. It makes it harder to see your business’s true financial health and can cause issues with tax authorities.
Open a separate bank account for your business transactions.
Use a dedicated credit card for business expenses.
Avoid withdrawing cash from business accounts for personal use.
Track all transfers between accounts carefully.
This separation provides a clear audit trail and simplifies preparing financial statements. For builders managing multiple projects, it also helps allocate costs accurately.
Track Your Job Costs Closely
Knowing how much each job costs is essential for pricing work correctly and maintaining profitability. Without detailed job costing, you might undercharge or miss opportunities to cut expenses.
Record all materials, labour hours, subcontractor fees, and equipment costs per job.
Use spreadsheets or job management software to monitor expenses.
Compare estimated costs with actual spending to improve future quotes.
Include indirect costs like transport and insurance in your calculations.
For instance, a builder who tracks labour hours and materials for each project can identify which jobs are most profitable and adjust bids accordingly.
Use Simple Accounting Software
Many builders and tradies avoid bookkeeping because they find accounting software complicated. However, modern tools are designed to be user-friendly and save time.
Choose software tailored for small businesses or trades, such as QuickBooks, Xero, or MYOB.
Automate invoicing, expense tracking, and bank reconciliation.
Generate reports to monitor cash flow, profit, and tax obligations.
Integrate with your bank for real-time updates.
Even if you’re not tech-savvy, investing time in learning basic software features can reduce errors and free you from manual record-keeping.
Keep Track of GST and Tax Obligations
Builders and tradies must stay on top of Goods and Services Tax (GST) and income tax requirements. Missing deadlines or miscalculating taxes can lead to penalties.
Register for GST if your turnover exceeds the threshold (usually $75,000).
Keep detailed records of GST collected and paid on purchases.
Set aside money regularly to cover tax payments.
Consult with an accountant for tax planning and lodgement.
For example, a tradie who sets aside 10% of income for tax avoids cash flow problems when tax bills arrive.
Regularly Review Your Financial Reports
Bookkeeping is not just about recording transactions but also understanding what the numbers mean for your business.
Review profit and loss statements monthly to see if you are making money.
Check your balance sheet to understand assets and liabilities.
Monitor cash flow reports to ensure you can cover expenses.
Use insights to plan for slow periods or invest in new equipment.
A builder who reviews reports regularly can spot trends early, such as rising material costs, and adjust accordingly.
Keep Backups and Secure Your Records
Losing financial records can be disastrous. Builders and tradies often work in environments where paper documents can get damaged or lost.
Back up digital records to cloud storage or external drives.
Keep paper copies in a safe, dry place.
Use password protection for accounting software.
Regularly update software to protect against security threats.
This practice ensures your bookkeeping data is safe and accessible when needed for audits or tax returns.
Consider Professional Help When Needed
While many builders and tradies handle bookkeeping themselves, professional help can save time and reduce errors.
Hire an accountant or bookkeeper for complex tasks like tax returns.
Use advisory services to improve financial management.
Outsource payroll if you have employees.
Seek advice on business structure and tax planning.
Even occasional consultations can provide valuable insights and keep your business compliant.
