Frequently Asked Questions
If you're GST-registered, you must charge GST on most work invoices at the current rate of 15%, unless the work qualifies as GST-exempt. This includes services like electrical work, plumbing, carpentry, and painting for both business and residential clients. Your invoice must clearly show the GST amount separately to remain compliant. If you're not currently GST-registered, you cannot charge GST, but once your annual turnover exceeds $60,000, you must register and start charging GST from that point forward.
According to NZ tax law, your work invoice must include: your name and GST registration number (if registered), the invoice date and unique number, your client's name and address, a clear description of work performed, the total amount charged, the GST amount (if applicable), and payment terms. Your contact details and bank account information should also appear for payment purposes. Missing any core details could make the invoice non-compliant with Inland Revenue standards, affecting your tax records and creating risks during audits.
Timing depends on your agreement with the client, but industry practice for NZ trades typically involves invoicing upon completion of the work, or at agreed milestones for larger projects. For smaller jobs (under $1,000), invoicing on the day of work completion is standard. Some contractors invoice weekly or monthly for ongoing maintenance contracts or retainer arrangements. The key is invoicing promptly while the work is fresh in both parties' minds, which improves payment collection rates significantly.
The invoice layout stays the same, but the details and terms differ importantly. For business clients, include their business name and IRD number if available, as they need these for tax deduction purposes. Residential homeowners need only their address. Business clients commonly expect longer payment terms (30 days is standard), while homeowners typically expect payment within 7–14 days. GST applies identically to both, though business clients are more familiar with GST implications and reverse-charge rules.
The IRD requires you to retain all invoices and supporting documents for at least 7 years from the date of the transaction. This includes copies of invoices sent to clients, payment proof, contracts, quotes, and any related documentation for each project. Good record-keeping protects you during tax audits and helps with cash flow analysis. Digital copies stored securely are acceptable, provided they're backed up and remain retrievable throughout the entire 7-year retention period.
Payment terms vary significantly by trade and client type. Residential clients typically expect "payment due within 7 days" or "payment on completion of work." Commercial clients in the construction industry often accept "Net 30" or "Net 14" terms. Some trades offer a 5% discount for payment within 7 days to accelerate cash flow. Retention clauses (withholding 5–10% of payment for 30 days) are standard in larger construction contracts. Always specify your accepted payment methods clearly.
No—GST doesn't apply if your client is based overseas or if the work qualifies as GST-exempt (certain repairs or maintenance work for registered charities). You must clearly state on the invoice why GST isn't charged, such as "Overseas client—GST not applicable" or "GST-exempt work." Keep detailed records proving the exemption, as Inland Revenue may query zero-rated invoices. GST-exempt work is uncommon for most trades, so verify the exemption status with your accountant if unsure.
Yes, absolutely customize the template to reflect your business identity and operational needs. Add your company logo, contact details, and GST registration number prominently. For trades with recurring clients or retainer arrangements, include fields for job reference numbers or project codes. You might add lines for warranty information, safety certifications, or materials supplied separately from labor charges. Keep the core legal elements (invoice number, date, GST breakdown) exactly as they appear to maintain full compliance.
