Frequently Asked Questions
Yes, if you're GST-registered, GST at 15% must appear on every invoice. Show it as a separate line item before the total, and include your GST registration number on the invoice. IRD expects to see GST clearly itemized for all roofing services—installation, materials, labor, and equipment hire. If you're not GST-registered, you cannot charge GST, but you should still note this on your invoice to avoid client confusion.
Break down your work by service type: roof inspection, material installation (metal sheets, tiles), ridge capping, gutter replacement, downpipe work, flashing, and scaffolding setup. Separating these helps clients understand what they're paying for and protects you if disputes arise. For material-heavy jobs, you can list materials separately from labor, which is standard in the roofing trade and useful for clients tracking costs against quotes.
Most NZ roofing contractors invoice within 7 days of job completion. For larger projects spanning weeks or months, issue progress invoices at each milestone—typically after inspection completion, material delivery, and final installation. This protects your cash flow and aligns with construction industry practice. Include clear descriptions of what was completed during each stage so invoices correspond to work actually done.
Standard NZ roofing invoices use 30-day payment terms (due within 30 days of invoice date). Some contractors negotiate 14 days for small jobs or 45 days for large commercial projects. Clearly state your payment terms on every invoice, including any early payment discount or late payment consequences. This sets expectations and helps avoid payment delays, which are common in construction if terms aren't explicit.
Yes, deposits are standard in NZ roofing. A typical deposit is 30–50% of the quoted price, taken before work begins. Create a separate deposit invoice showing the deposit amount and explicitly stating that this is a prepayment on the final invoice. When the job completes, issue the final invoice and deduct the deposit received. This creates clear documentation for both you and the client.
Retentions (or holdbacks) are common in NZ construction: the client withholds 5–10% of your invoice total for 30–60 days after job completion to ensure quality workmanship. Your invoice should clearly show the retention amount and when it will be released. This protects the client against defects but affects your cash flow, so factor retentions into your payment schedule if you're financing ongoing work.
IRD requires you to retain all invoices and supporting documents for seven years. This includes the original invoice, any amendments, payment records, and proof of GST charged or claimed. Keep roofing job photos, quotes, and contracts alongside invoices—they support your records if IRD questions your GST or income. Digital storage is acceptable as long as files remain legible and accessible.
Your invoice must include: your business name and GST number (if registered), invoice number and date, client's name and address, itemized roofing services with quantity and price, GST amount (15%), total due, payment terms, and your payment method details. IRD requires this information for tax compliance. Include a brief description of the roofing work completed—specifying materials like metal sheets or tile type adds clarity and helps distinguish invoices for different projects.
