Bookkeeping for Electricians: A Practical Guide for Australian Electrical Businesses

Why Bookkeeping Matters More Than You Think for Electricians

Most electricians go into business to do electrical work, not to sit behind a desk managing spreadsheets. But the financial side of running an electrical business is what determines whether you end up with a profitable trade or a stressful one.

Poor bookkeeping is one of the top reasons trade businesses fail within the first five years. Not because the work dries up, but because the owner cannot see clearly where money is going, undercharges on jobs, misses BAS deadlines, or faces a nasty tax bill they were not prepared for.

The good news is that with the right tools and habits, bookkeeping for an electrical business does not need to take more than a few hours a month.

How an Electrical Business Is Different from Other Industries

Before getting into specifics, it helps to understand what makes bookkeeping for electricians a little different from, say, bookkeeping for a retailer or a consultant.

Job-based revenue. Almost all your income comes from individual jobs. Each job may have its own quote, materials list, labour component, and invoice. Tracking profitability job by job is important and harder to do without the right setup.

Materials and stock. You carry consumables, cable, fittings, and equipment. Some of this gets charged directly to jobs, some sits in your van or workshop, and some gets used up or written off. Managing materials in your books requires a bit of extra thought.

Vehicles and tools. Electricians often have significant assets in vehicles and test equipment. These need to be depreciated correctly, and the ongoing costs of running and maintaining them need to be tracked.

Subcontractors. Many electrical businesses use subcontractors for larger jobs or when capacity is tight. Payments to subs need to be recorded and reported correctly, including any PAYG withholding obligations.

Setting Up Xero for an Electrical Business

Xero is the go-to accounting platform for Australian trades, and for good reason. It integrates with job management apps, connects directly to your bank, and handles BAS preparation in a way that makes lodgement straightforward.

Here is how to set it up properly from the start.

Chart of Accounts

Your chart of accounts is the backbone of your bookkeeping. For an electrical business, the categories you will use most often include:

Income:

• Electrical Labour
• Materials Supplied
• Service Call Revenue
• Commercial Work
• Residential Work

You can keep it simple or break it down by job type. The more detail you track, the more useful your reports will be, but do not overcomplicate it early on.

Expenses:

• Materials and Consumables
• Tools and Equipment (under $150 expensed, over $150 depreciated as an asset)
• Motor Vehicle Expenses
• Fuel
• Subcontractors
• Insurance (public liability, workers compensation, vehicle)
• Licences and Registrations
• Advertising and Marketing
• Accounting and Bookkeeping Fees
• Protective Clothing and Uniforms

Tracking Categories

If you work on multiple job types or across different regions, Xero's tracking categories let you report on profitability by segment. For example, you could set up a tracking category called Job Type with options like Residential, Commercial, and Industrial. This lets you see at a glance which type of work is most profitable.

Connecting Bank Feeds

Connect your business bank account and any business credit cards to Xero. This pulls transactions in automatically and makes reconciliation far faster. Most Australian banks support direct feeds with Xero.

Managing Job Costing

One of the most valuable things you can do as an electrician is track your actual costs versus quoted costs on each job. This is called job costing, and it reveals whether your quoting is accurate or whether you are regularly undercharging.

In Xero, you can do basic job costing by using the tracking categories mentioned above. For more detailed job costing, consider a connected job management app like ServiceM8, Tradify, or AroFlo. These apps let you build quotes, schedule jobs, record time on site, and attach materials to specific jobs, then sync everything back to Xero.

GST and BAS for Electricians

All Australian electricians with annual turnover above $75,000 must be registered for GST. If you are under that threshold, registration is optional but often worth doing if your clients are businesses who can claim back the GST.

How GST works on your invoices:

Most of your electrical work will attract GST at 10%. If you charge a client $1,100 for a job, $100 of that belongs to the ATO. You are collecting it on their behalf and must remit it in your next BAS.

GST credits on purchases:

You can claim back the GST you pay on business expenses. Materials, tools, fuel, and other business costs typically include GST that you can offset against what you owe. This is called an input tax credit.

BAS lodgement:

Your BAS is lodged either monthly or quarterly depending on your turnover. Most small electrical businesses lodge quarterly. The due dates are:

• Quarter ending 30 September: due 28 October
• Quarter ending 31 December: due 28 February
• Quarter ending 31 March: due 28 April
• Quarter ending 30 June: due 28 July

Xero calculates your BAS figures automatically once your transactions are reconciled and coded correctly. If you use a BAS agent, they can lodge directly from Xero.

Tax Deductions Electricians Often Miss

There are several legitimate deductions that electrical businesses frequently overlook or underclaim.

Tools and Equipment

Tools used exclusively for work are fully deductible. Under the instant asset write-off rules, small businesses can often deduct the full cost of equipment in the year of purchase rather than depreciating it over several years. Check with your accountant for the current threshold and eligibility rules.

Vehicle Expenses

If you use a vehicle for work, you can claim a deduction for business use. The method depends on whether you use the logbook method or the cents per kilometre method. For most electricians who use their van almost entirely for work, the logbook method will result in a larger deduction.

You can claim fuel, registration, insurance, servicing, and depreciation on the vehicle itself.

Home Office

If you do quoting, administration, or scheduling from a home office, you may be able to claim a portion of home running costs. The ATO has an updated fixed rate method that simplifies this calculation.

Protective Clothing and Uniforms

Clothing that is genuinely protective (steel-capped boots, hi-vis workwear) or a registered and distinctive uniform is deductible. Generic clothing is not, even if you only wear it for work.

Licences and Professional Memberships

Electrical licences, Master Electricians membership fees, and continuing education costs are all deductible as they relate directly to earning your income.

Payroll for Electrical Businesses

If you employ apprentices or other staff, payroll adds a layer of complexity to your bookkeeping. Xero Payroll handles the following automatically once set up:

• Gross pay calculations based on hours worked
• Tax (PAYG withholding) deductions
• Superannuation calculations and payment notifications
• Single Touch Payroll (STP) reporting to the ATO
• Leave accruals

The most important thing is to get employees set up correctly from day one, including the right award or enterprise agreement. Electrical workers are typically covered by the Electrical, Electronic and Communications Contracting Award. Getting pay rates and allowances right upfront avoids costly corrections later.

Managing Subcontractors

Using subbies is common in the electrical trade. From a bookkeeping perspective, there are a few important things to get right.

Separate from employees: Subcontractors are not employees and are not on your payroll. You pay them their invoice amount, which is a business expense.

GST on subbies: If a subcontractor is registered for GST, their invoice will include GST that you can claim as an input tax credit.

Taxable Payments Annual Report (TPAR): This is one that many electrical businesses miss. If you pay subcontractors for building and construction services, you must lodge a Taxable Payments Annual Report with the ATO each year by 28 August. Xero can generate this report automatically if you have set up your supplier records correctly.

Cash Flow Tips for Electricians

Cash flow is the number one financial pressure for most trade businesses. A few habits make a big difference.

Invoice promptly. The longer you wait to invoice after a job, the longer you wait to get paid. Ideally, invoice on the day the job is complete.

Set clear payment terms. Net 7 or Net 14 is standard for residential work. For commercial clients, Net 30 is common but push for faster where you can.

Follow up on overdue invoices. Xero can send automatic payment reminders. Turn these on. Chasing money is uncomfortable, but automated reminders are neutral and effective.

Hold back some cash for BAS and tax. A simple rule: set aside 25 to 30% of your net income as each payment comes in, and keep it in a separate account. When your BAS or tax bill arrives, you will have the funds ready.

Using AI Tools to Simplify Your Bookkeeping

Tools like SortBooks take the most time-consuming parts of bookkeeping off your plate. By connecting to Xero, SortBooks can automatically categorise your transactions, flag anything that looks unusual, and keep your bank reconciliation up to date without you having to do it manually.

For a busy electrician who is on the tools most of the day, this kind of automation can mean the difference between doing your bookkeeping on a Sunday evening for two hours versus spending fifteen minutes reviewing what the system has already done for you.

Clean, up-to-date books mean you always know where your business stands, you never miss a BAS deadline, and your accountant spends less time sorting out your records at tax time, which saves you money.

Getting Started

You do not need to overhaul everything at once. Start with the basics:

1. Open a dedicated business bank account if you have not already
2. Set up Xero with a chart of accounts suited to an electrical business
3. Connect your bank feed
4. Create a template invoice with your payment terms
5. Start coding transactions as they come through

Once those habits are in place, you can layer in job costing, payroll, and more sophisticated reporting as your business grows.

The goal is clean books that give you a clear picture of your financial position at any point in time. For an electrician running their own business, that clarity is worth more than most people realise.
