The Bookkeeping Basics Every Tradie Should Get Right

When you're running a trade business, every dollar counts. You work hard to win jobs, manage staff, order materials, and keep customers happy,  but if your bookkeeping isn't keeping pace, small oversights can quickly eat into your profit margins.

The good news? A few simple bookkeeping routines can help you stay on top of your finances, improve cash flow, and make sure you're getting paid what you're worth.

1. Track Job Costs Properly

One of the biggest mistakes tradies make is not separating labour costs from materials when tracking jobs.

Let's say you're completing a bathroom renovation. You spend $4,500 on materials and 60 hours of labour. If you only track the total invoice amount and don't monitor those costs separately, it's difficult to know whether the job was actually profitable.

Using software such as Xero or MYOB allows you to allocate expenses to individual jobs and compare your estimated costs against actual costs. Over time, this helps you quote more accurately and identify which types of jobs generate the best returns.

2. Follow Up Debtors Quickly

Late payments can cause serious cash flow headaches for small businesses.

Many tradies finish a job, send the invoice, and then get busy with the next project. Before they know it, 30, 60, or even 90 days have passed without payment.

Establish a simple routine:

• Send invoices immediately after work is completed.

• Check outstanding invoices weekly.

• Follow up overdue accounts promptly.

• Use automated reminders through your accounting software.

The sooner you follow up, the more likely you are to get paid without lengthy delays.

3. Record Deductible Expenses As You Go

Missing receipts and forgotten purchases can add up over the course of a year.

Fuel, tools, work clothing, vehicle expenses, mobile phone costs, and small equipment purchases may all be deductible business expenses. However, they're only useful at tax time if they've been recorded properly.

Use receipt-capture apps connected to Xero or MYOB, or develop a habit of photographing receipts as soon as purchases are made. Spending a few seconds now can save hours later.

Real-World Example

A local electrical contractor was consistently busy but couldn't understand why profits weren't growing.

After implementing proper job-cost tracking, they discovered several projects where material costs had increased significantly but their pricing hadn't kept pace. By separating labour and materials in their bookkeeping system, they were able to adjust future quotes and improve profitability on similar jobs.

The result? Better margins without taking on additional work.
