Bathroom Renovation Invoice Template - Australia

You must include GST (10%) on all bathroom renovation services and materials supplied in Australia, including labor, fixtures, tiling, plumbing work, and disposal. Your bathroom renovation invoice should show the GST amount separately, with the total including GST. However, if your business turnover is below the $75,000 GST threshold, you won't be required to register for GST and don't need to charge it. Always verify your registration status and include your ABN on your invoice, which is required for invoices over $75.

Yes, separating labor from materials gives clients clear visibility into where their money goes and helps justify your costs. For a bathroom renovation, list materials separately (tiles, fixtures, vanity, shower screen, waterproofing) with quantities and rates, then itemize labor tasks (demolition, rough-in plumbing, installation, finishing). This breakdown also simplifies GST tracking and makes it easier to adjust costs if the client wants to provide their own materials or modify the scope.

Create separate invoices for each renovation phase: demolition and disposal, rough-in works (plumbing and electrical), installation of fixtures and fittings, and finishing. Each invoice should reference the main project, include itemized work completed in that stage, and specify the payment due date. Progress invoicing protects your cash flow during longer projects, ensures clients see value at each stage, and reduces disputes about final costs. Include a note on earlier invoices that further invoices will follow as work progresses.

List each fixture with its model, quantity, and price as a separate line item: vanity unit (900mm), toilet suite, shower screen and door, exhaust fan, mirrors, and any custom shelving. Include the cost of supply and installation together, or separate them if the client is sourcing materials themselves. Add descriptive specifications (e.g., "premium porcelain floor tiles, 25 sqm") so clients understand exactly what they're paying for. This detail protects both you and the client by preventing misunderstandings about product quality and specifications.

List demolition as its own line item with a clear description: "Bathroom demolition and disposal of existing fixtures, fittings, and waste materials." Specify whether the cost includes removal to the tip or if there's a separate disposal fee. Many contractors bundle this into a lump sum based on bathroom size and complexity, while others charge by the hour. Be transparent about what's included—asbestos removal, hazardous waste, or extra tip fees should be listed separately and discussed with the client before work begins.

Issue a separate variation invoice or amendment that clearly references the original invoice number and project. Describe the change in detail (e.g., "additional tiling of feature wall, 8 sqm premium porcelain at $95/sqm"), include the new cost, and note whether it affects the project timeline. Have the client approve and sign off on variations before invoicing, so there's no dispute about extra charges. On the final invoice, reference all variation invoices issued, showing the original amount, variations, and total.

Most Australian bathroom contractors require a 50% deposit on signing the contract to purchase materials, with the remaining 50% due on practical completion or final invoice. Some offer 50-30-20 staged payments aligned with project milestones (deposit, mid-stage, completion), or 7–14-day terms after invoicing. Clearly state payment terms on your invoice and specify accepted payment methods (bank transfer, credit card, check). Document all terms in your initial quote or contract to avoid disputes.

No, most bathroom contractors combine supply and installation into a single invoice for each fixture or work category. This is simpler for accounting and clearer for clients. However, if a client is sourcing materials themselves and you're only installing, issue an invoice for labor only. Conversely, if you're supplying fixtures for them to install (rare), invoice for supply separately with clear terms about liability and warranty once items leave your care. Always specify in the invoice line item whether costs include installation or not.
