What is a Time And Material Invoice?
The Time and Materials Invoice is essential for businesses operating in New Zealand that provide services and materials on a non-fixed-price basis. This document type is particularly relevant when the exact scope of work cannot be predetermined or when services are provided on an ongoing basis. The invoice must comply with New Zealand's GST requirements and include specific elements such as GST registration numbers, tax calculations, and detailed breakdowns of time and materials. It serves as a formal record of actual work performed and materials supplied, protecting both service providers and clients by providing transparent cost tracking and billing. This document type is commonly used in professional services, construction, consulting, and various other sectors where billing is based on actual resources utilized rather than fixed prices.
Frequently Asked Questions
Is a Time and Material Invoice legally binding in New Zealand?
Yes, a Time and Material Invoice is legally binding in New Zealand once the client accepts the work and payment terms. Under New Zealand contract law, the invoice represents an agreement for payment based on actual hours worked and materials used. The invoice must comply with GST requirements under the Goods and Services Tax Act 1985 to be valid for tax purposes.
How does a Time and Material Invoice differ from a fixed-price invoice in New Zealand?
A Time and Material Invoice charges for actual hours worked plus materials used, while a fixed-price invoice charges a predetermined amount regardless of time spent. Time and Material invoices provide cost transparency and are ideal for variable-scope projects, but both must comply with the same GST requirements under New Zealand law.
Can I charge GST on my Time and Material Invoice if I'm not GST registered in New Zealand?
No, you cannot charge GST if you're not registered for GST in New Zealand. Only GST-registered businesses can add GST to their invoices. If your annual turnover exceeds $60,000, you must register for GST, but registration is optional below this threshold.
How long should I keep Time and Material Invoice records in New Zealand?
You must keep Time and Material Invoice records for at least 7 years in New Zealand as required by the Tax Administration Act 1994. This includes the original invoices, time sheets, material receipts, and payment records. Digital copies are acceptable if they're complete and accessible.
How quickly can I create a Time and Material Invoice in New Zealand?
A Time and Material Invoice can typically be created within 30 minutes using a template, provided you have accurate time records and material costs. The process involves calculating hours worked, adding material costs, applying GST if registered, and ensuring all mandatory New Zealand invoice requirements are included.
Can a client refuse to pay my Time and Material Invoice in New Zealand?
A client can only legally refuse payment if the invoice contains errors, doesn't match agreed terms, or if the work wasn't performed as contracted. Under the Fair Trading Act 1986, all invoice details must be accurate and not misleading. If payment is wrongfully refused, you can pursue recovery through the Disputes Tribunal or courts.
Why is my Time and Material Invoice being rejected for missing GST details in New Zealand?
Your invoice likely lacks mandatory GST information required under the Goods and Services Tax Act 1985. GST invoices over $50 must include your GST number, the words 'tax invoice,' GST amount, and total amount including GST. Missing any of these elements makes the invoice non-compliant and may affect the client's GST claims.
About the Time And Material Invoice
When you provide services or materials to clients on a variable-cost basis, you need a Time and Material Invoice that meets New Zealand's legal and tax requirements. This document allows you to bill clients for actual hours worked and materials consumed, providing transparency and legal protection for both parties in your business relationship.
When do you need this document?
You'll need a Time and Material Invoice when undertaking projects where the exact scope cannot be predetermined. Construction contractors use these invoices when building costs fluctuate based on site conditions and material prices. IT consultants rely on them for software development projects where requirements evolve during implementation. Professional service firms like lawyers, accountants, and engineers use time and material billing when client needs extend beyond initial project estimates. Maintenance and repair services also benefit from this billing method when the extent of work becomes clear only after assessment.
Key legal considerations
Your Time and Material Invoice must include essential elements to ensure legal compliance and enforceability. Under the Fair Trading Act 1986, you must provide accurate descriptions of services and materials to avoid misleading conduct claims. Include detailed breakdowns of hourly rates, time spent on specific tasks, and itemized material costs with quantities and unit prices. The Contract and Commercial Law Act 2017 requires clear payment terms and service descriptions to support contract enforcement. Document retention becomes crucial under the Tax Administration Act 1994, which mandates keeping invoice records for seven years. Ensure your invoice includes authorized signatures from both parties to establish legal agreement on charges incurred.
Legal requirements in New Zealand
The Goods and Services Tax Act 1985 imposes specific requirements for invoices exceeding $1,000, including your GST registration number, tax calculation breakdowns, and total GST amounts. Your invoice header must display your business's full legal name as registered under the Companies Act 1993, along with your complete business address and contact information. Include the client's full legal name and address to establish clear billing relationships. Specify the service period covered by the invoice and ensure GST calculations are clearly separated from base charges. Your invoice numbering system must be sequential and unique to support audit requirements. Payment terms should align with standard commercial practices, typically 20-30 days from invoice date, unless otherwise agreed in your service contract.
