Parts Tracking for Appliance Repair Businesses in Australia

Why parts tracking matters more than you think

In appliance repair, parts can represent 30–60% of a job's total cost. If you're not tracking parts expenses accurately, you don't know your real profit margin on any given job. A $250 washing machine repair might look profitable until you realise the control board cost you $140 wholesale, the seal kit was $35, and you spent 30 minutes driving to the supplier. Suddenly your margin is razor-thin. Systematic parts tracking reveals which jobs are genuinely profitable and which ones you're doing at a loss.

Tracking parts costs per job

Every part you use should be linked to a specific job. This sounds obvious, but most solo operators buy parts in bulk or grab multiple items from a supplier in one trip and lose track of which part went where.

• •Record the part description, part number, supplier, and cost against each job when you order — not when you install
• •Apply a consistent markup: 25–40% on parts is standard in the Australian appliance repair industry
• •Track shipping or delivery costs separately — these eat into margins if you don't account for them
• •Note warranty status: is the part covered under the appliance's manufacturer warranty, or is the client paying?
• •Use a per-job expense log (even a simple spreadsheet) rather than relying on memory or a pile of receipts

Managing supplier receipts and warranty parts

Suppliers issue receipts, invoices, and credit notes. Manufacturers issue warranty authorisations and replacement parts. Keeping all of this organised is critical for cash flow and compliance. Photograph every supplier receipt immediately and file it digitally against the job. For warranty parts, record the warranty claim number, the manufacturer's authorisation, and whether you're being reimbursed for labour as well as parts. Some manufacturers pay a flat labour rate for warranty work — make sure you're claiming it. Unclaimed warranty labour is money left on the table.

Invoicing for parts and labour

Clients expect to see parts and labour as separate line items on their invoice. This transparency builds trust and justifies your pricing. List each part with its description and price (including your markup), then show labour as a separate charge. If the job involved a diagnostic visit and a return visit, show both. Include any travel charges if applicable. Send the invoice immediately after completing the repair — delays in invoicing lead to delays in payment. For jobs over $500, consider requesting a deposit before ordering parts to protect your cash flow.

Expense management for BAS and tax time

If you're registered for GST, every parts purchase includes a GST component you can claim back as an input tax credit. But only if you have a valid tax invoice. The ATO requires you to keep records of all business expenses for five years. At BAS time, you need to report your total purchases (including parts) and claim GST credits. Categorise your expenses as you go — parts, fuel, tools, insurance, vehicle costs — rather than sorting through a year's worth of receipts in June. A digital receipt scanner and expense tracker makes this almost effortless. The time you save at BAS time pays for the habit many times over.
