Flat Fee Agreement Template for New Zealand

A Flat Fee Agreement is a legally binding contract that establishes fixed pricing for specific services in New Zealand. Unlike hourly billing arrangements, this document provides cost certainty for clients while allowing service providers to price their expertise and efficiency appropriately. You'll need this agreement when offering services where the scope can be clearly defined and the total effort reasonably estimated.

When do you need this document?

You should use a Flat Fee Agreement when providing well-defined professional services such as website development, accounting packages, legal document preparation, or marketing campaigns. This arrangement works particularly well for consultants offering standardised services, contractors completing specific projects, or businesses providing recurring services with predictable requirements. The agreement is also valuable when clients prefer budget certainty over time-based billing, especially for small businesses or individuals who need to manage cash flow carefully.

Key legal considerations

Your Flat Fee Agreement must clearly define the scope of services to avoid disputes about what's included in the fixed price. Include detailed specifications of deliverables, timelines, and any assumptions underlying your pricing. Address change management procedures for work outside the agreed scope, as additional requests can significantly impact profitability. Consider liability limitations and professional indemnity requirements, particularly for advice-based services. Payment terms should specify GST treatment, invoicing schedules, and consequences of late payment. Include termination clauses that protect both parties while ensuring fair compensation for work completed.

Legal requirements in New Zealand

Under the Contract and Commercial Law Act 2017, your agreement must contain essential contractual elements including offer, acceptance, and consideration. The Consumer Guarantees Act 1993 applies when providing services to consumers, requiring services to be performed with reasonable care and skill and fit for purpose. You must comply with Fair Trading Act 1986 requirements by ensuring service descriptions are accurate and not misleading. GST obligations under the Goods and Services Tax Act 1985 require proper tax treatment if you're GST-registered. Privacy Act 2020 compliance is essential when collecting or handling client personal information. Consider whether the Construction Contracts Act 2002 applies for building-related services, as it provides specific payment and dispute resolution rights.
