Bathroom Repair Invoice Template - New Zealand

GST in New Zealand is 15% and applies to most bathroom repair services. If you're GST-registered, you must show the GST amount separately on your invoice as a line item, with the total including GST clearly stated. For example, a $285 toilet replacement becomes $327.75 with GST added. The invoice must display your IRD-registered GST number, your customer's name and address, a unique invoice number, and the date. If you're not GST-registered (turnover under $60,000), you simply invoice without GST and note your non-registered status. Keep detailed records of all GST-inclusive and exclusive amounts for tax compliance and accurate financial reporting throughout the financial year.

Every NZ invoice requires your business name, address, and GST registration number (if applicable), the invoice date and a unique invoice number, the customer's name and address, a clear description of services provided, the invoice amount including GST (with GST shown separately if registered), payment due date, and payment instructions. For bathroom repair work, describe the specific services performed—such as "toilet cistern replacement" or "shower grout resealing"—rather than vague terms. Include the quantity and hourly rate or fixed price for each item. The IRD requires these details to be retained for seven years, so your template should support detailed record-keeping and easy retrieval of this information.

Yes, call-out fees and weekend or emergency rates are common and acceptable on NZ bathroom repair invoices, particularly for urgent work like burst pipes or blocked drains requiring immediate attention. These charges should be clearly itemized separately from the service work itself—for example, listing "$75 Emergency call-out fee - weekend service" as its own line item. However, the fee must be reasonable and disclosed to the customer before you attend, ideally in writing or via phone confirmation. Ensure all charges are transparent on the final invoice; customers are less likely to dispute fees they agreed to beforehand. Many NZ plumbing businesses charge between $50–$150 for call-outs depending on location and urgency.

Most bathroom repair businesses in New Zealand invoice for immediate or net 7–14 day payment, depending on the job size and customer relationship. Small jobs under $500 often expect payment on completion, while larger renovation projects may allow 7–30 days. You should specify your payment due date clearly on the invoice (for example, "Due 14 days from invoice date") and list your accepted payment methods—bank transfer, cash, card, or online payment platforms. For significant work or new customers, requesting a deposit before starting (typically 25–50% of the total) protects you against non-payment. This term should be agreed in writing and reflected on the invoice, creating a clear record if disputes arise later.

Separating materials from labor on your bathroom repair invoice provides transparency and helps clients understand value. For instance, you might list "$285 Toilet cistern (part) + installation labor" or separate them entirely as "$200 Toilet cistern replacement (material)" and "$85 Installation labor." Some plumbers bundle these as one line item with a fixed price, which is also acceptable. The approach depends on your business practice and customer preference. However, for larger renovations involving multiple fixtures, itemizing clearly helps clients track spending and allows you to adjust labor if complications arise during work. Whichever method you choose, use it consistently across all invoices to maintain professional records and simplify bookkeeping.

Requesting a deposit for bathroom repair work is standard practice in New Zealand, especially for jobs exceeding $500 or involving purchased fixtures. A typical deposit is 25–50% of the estimated total cost, payable before you purchase materials or schedule labor. This protects you against job abandonment and covers material costs if complications arise. Document the deposit agreement in writing—ideally via email or formal quote—and reference it on your first invoice. When the final invoice is issued, clearly show the deposit as a credit, with the balance due underneath. This transparency prevents confusion and disputes. For smaller jobs or trusted repeat customers, you may waive deposits, but written agreement remains important for compliance and record-keeping.

Including warranty details on your invoice builds customer confidence and protects your business. Add a line near the bottom stating the scope and duration—for example, "12-month warranty on labor" or "Materials covered by manufacturer's warranty, labor guaranteed for 90 days." Make this clear and specific rather than vague promises. If certain parts or services carry no warranty, state that explicitly to avoid misunderstandings later. Document any terms and conditions separately in a written agreement if the job is substantial, then reference that agreement on the invoice. Different bathroom fixtures have different manufacturers' warranties (tap aerators, cisterns, etc.), so clarify which warranties you're guaranteeing and which remain the customer's responsibility. This clarity reduces callback requests and dispute claims.

The IRD requires you to retain all invoices, receipts, and supporting financial records for seven years from the transaction date, regardless of payment status. Your bathroom repair invoice template should produce permanent, legible records—either printed copies stored securely or digital versions backed up safely. These records must be accessible if the IRD requests them for tax audit, and you need them to match invoiced work against bank deposits and expense claims. Digital storage is acceptable provided you can reproduce invoices in legible form. Organizing invoices by date or customer name makes retrieval easier during tax time and ensures you never accidentally discard records you're legally required to keep.
