Is an electrical business profitable? Where the money goes, and how to keep it

Use AxiomBlue’s quote, time, material and billing records to review the quoted installation on a consistent basis. Calculate contribution after checking direct costs, then review overhead, owner pay and cash separately; an ATO expense ratio is not a profit margin.

Key facts

What the worked example measuresDirect contribution: agreed revenue less the specified direct costs, before business overheads, owner management pay and tax.
What the benchmark measuresATO 2023-24 total-expense-to-turnover ratios for the stated industry; not a profit or salary measure.
What cash measuresReceipts and payments in the period. An invoiced amount is not proof that cash has arrived.

Use AxiomBlue job records to review the quoted installation

  1. Open the accepted AxiomBlue installation quote and job, check Time Tracking and Materials including parts used from van stock, and retain testing/return-work costs. Reconcile an approved extra circuit through Professional Variations rather than treating every cost overrun as billable.
  2. Check the agreed revenue and direct costs against the worked example below, using the job reference to find missing entries or supporting supplier records. Apply the stated labour-cost basis; do not use the customer’s billable rate as an employee wage cost. Calculate the example/worksheet totals explicitly rather than assuming an incomplete record is the final result.
  3. Review the related invoice/claim and customer balance in AxiomBlue to distinguish billed value from payment. Use the resulting cost evidence to revise the next quote. Your accountant or accounting system supplies the wider overhead, net-profit, tax and owner-pay assessment; these job records do not produce that conclusion by themselves.

Check the work and the costs you are comparing

Include preparation, site access, testing, travel and parts used from van stock. Keep approved additions separate from work already included in the quote.

Use the same scope and period on both sides of the comparison. Include the work needed to deliver the service, including travel, setup and return visits where relevant. Use actual current employment and supplier costs; the illustrative rates below are not award rates or recommended prices.

Read the ATO expense benchmark as expenses, not take-home profit

The ATO’s 2023-24 benchmark for electrical services reports total expenses as a percentage of turnover, excluding GST. The average expense ratios are 59%, 67%, 81% for the turnover bands below. These are expense-to-turnover ratios, not net profit margins or owner salaries.

Scope matters: Installation, repair, maintenance, assembly, identification and design of electrical equipment/networks; excludes auto electricians and air-conditioning specialists.

The ATO calculation subtracts payments to associated persons from total expenses. An owner’s drawings are also not the same as a delivery wage or a business expense. Subtracting a benchmark expense ratio from 100% does not show profit after paying an owner for all their work. Compare like-for-like records and budget owner delivery and management time separately.

Use the industry table to investigate differences, not to price an individual job. Businesses in different turnover bands are different populations; the table does not prove that growing your business will cause its margin to fall.

Annual turnover, ex GSTTotal expenses ÷ turnover rangeAverage total expenses ÷ turnover
$50,000 – $200,00051% to 68%59%
$200,001 – $500,00059% to 75%67%
More than $500,00075% to 86%81%

Worked example: a quoted installation

Illustrative assumptions, all amounts excluding GST: An agreed $2,000 installation; ten planned paid hours at an assumed loaded cost of $60, plus $900 parts and other direct costs. Access and testing require three more paid hours.

The assumed delivery labour cost includes a budget allowance for the person doing the work, including owner delivery time where applicable. It is not a current legal pay minimum. Business overheads, owner management/admin time, finance costs and tax still need to be considered separately.

Planned direct contribution is $2,000 − $600 − $900 = $500 (25.0%). Actual direct contribution is $2,000 − $780 − $900 = $320 (16.0%). The $180 difference is the specified additional delivery cost; it is not an industry result or a claim about typical software savings.

Keep any approved extra revenue as a separate change to the calculation. For a fixed-price agreement, more recorded hours do not automatically increase the agreed price. If an invoice remains unpaid, the contribution calculation does not make it cash.

Example measurePlannedActual
Agreed revenue$2,000$2,000
Specified delivery labour$600$780
Other specified direct costs$900$900
Direct contribution before overhead and other owner work$500 / 25.0%$320 / 16.0%

Separate job contribution, business profit and owner pay

Job contribution helps identify underpriced scope or a delivery overrun. Business profit also depends on overheads and other costs across the period. Owner pay and drawings must be interpreted for your business structure; the amount left in the example is not a salary estimate.

Use a cost rate that reflects what delivery actually costs your business. Mark missing time or material records before relying on a job margin. If a job cost view excludes an expense, allow for it in the wider business review rather than treating the displayed margin as net profit.

Keep the records needed for the next pricing decision

In AxiomBlue, keep job time, materials and the agreed price together so you can review delivery and billing. Free supports a limited one-user core workflow; Basic adds capacity and photo/document uploads.

Professional is required for recurring job series, variation approvals, weekly timesheets, business reports and workflow automation. Inspect the relevant records in the demo or on the required plan. A job cost view does not replace a profit and loss statement, payroll or bank reconciliation.

Check completed work against invoices and receipts. Record agreed scope changes before including them in revenue, and review work already billed before preparing another invoice.

Use the review to change the next quote or contract

Look for a repeated cause: underestimated preparation, travel, a return visit, extra scope or missing cost records. Update the estimate and explain any revised price or exclusion before the next job is agreed.

Check a week or month that includes ordinary work and an exception. Review the underlying records with your bookkeeper or accountant when the job contribution and business accounts tell different stories. Check current employment, tax and contractual obligations against the relevant official guidance.

Common questions

Questions about electrical profitability

Is an electrical business profitable?

A electrical business is profitable when its revenue covers delivery costs, overheads and an appropriate allowance for the owner’s work. Start with actual completed work and costs, then check whether the invoices have been paid.

Does an ATO expense ratio tell me my profit margin?

No. It compares specified tax-return expenses with turnover for a stated industry and year. Associated-person payments are removed from the ATO expense calculation. It does not establish net profit after owner pay, drawings or cash available to take home.

What does the worked example leave out?

The example identifies the specified direct costs and contribution. Business overheads, owner management/admin work, finance costs and tax remain outside it. Its rates are illustrative assumptions, not award rates or recommended customer prices.

Can a profitable job still cause a cash problem?

Yes. Work and costs can be recorded before the customer pays. Check invoices, receipts, supplier commitments and other outgoing payments alongside the contribution calculation.

Which AxiomBlue plan do the records need?

Free supports one user and limited core jobs, time and invoicing. Uploads start on Basic. Recurring series, variation approvals, weekly timesheets, reports and automations require Professional; inspect those in the demo or on the required plan.

Put it to work

Your practical checklist

  1. Select completed work and the matching agreed price.
  2. Check paid delivery time, materials, travel and missing records.
  3. Allow for overheads and the owner’s delivery and management work.
  4. Use the benchmark only if its industry and measure match your business.
  5. Reconcile invoices and receipts, then update the next estimate.
