Software development agreements for custom builds and tech projects

The main issue is usually not whether the work is called development, implementation or consulting, but whether the contract actually matches the project. Software builds often involve changing scope, staged delivery, testing, third-party tools, access to data and questions about who owns what at the end. If those points are left vague, disagreements can surface once time and money have already been spent. A well-structured agreement helps record the commercial deal in a way that is easier to work with during the project, not just after a problem appears.

It commonly covers the project scope, deliverables, milestones, payment structure, timing assumptions, client responsibilities, change requests, acceptance or testing steps, intellectual property ownership or licensing, confidentiality, data handling, warranties, liability settings, termination rights and any post-launch support. Some projects also need clearer wording around subcontractors, open-source components, integrations or hosted environments. The right drafting depends on your actual data flows, including what you collect, why you use it and who receives it, because those practices can affect what the agreement should say about data and access.

A software development agreement is often used where the build is more technical, more bespoke or more closely tied to product functionality than a standard website project. It may need deeper treatment of source materials, development milestones, testing, licensing, data access and support obligations. An implementation agreement, by contrast, is often centred on deploying or configuring an existing system. The label matters less than the work being done, so we look at the real project structure before shaping the contract wording.

Templates can be useful for spotting common headings, but they often fall short once a project involves custom code, staged delivery, shared responsibilities or ongoing support. They may not deal properly with ownership of pre-existing materials, acceptance criteria, change control, third-party dependencies or practical data access issues. They also tend to assume a simple project flow that does not reflect how software work actually unfolds. This service helps you assess and reduce risk through better drafting, but outcomes will still depend on how the parties perform the project in practice.

Useful information includes a description of the software or services, who the parties are, whether the work is fixed scope or iterative, the planned milestones, payment approach, any support period, who will own the finished work and whether existing code, tools or third-party services are involved. If personal or sensitive information may be accessed, it also helps to explain how information is collected, used, stored and shared in practice. Draft proposals, statements of work or prior contract versions can also speed up the review.

We operate completely online, which means we can help you wherever you are in New Zealand. We have office spaces in Sydney, and in Melbourne, but our use of technology allows our team members to work remotely from around the world. Our legal team are mostly based in Sydney, Melbourne, Brisbane and Perth. We also have a London office for Sprintlaw UK.

Our legal team is made up of experienced lawyers, who are specialists in various areas of law and hold an Australian legal practising certificate. None of our Sprintlaw lawyers are New Zealand qualified lawyers and they do not currently hold a New Zealand practising certificate.

They provide legal services working remotely from Australia via our 'legal consultancy' model, through which (under section 6 and section 35 of the New Zealand Lawyers and Conveyancers Act 2006) our Australian legal team are permitted to provide legal services to New Zealand businesses provided they do not provide services in certain 'reserved' areas of law. You can read our FAQ page to learn a bit more about our 'legal consultancy' model.

Given the strong similarities between Australian and New Zealand law, and the areas of law in which we practice (being small business and startup law), we do not view the fact that our lawyers have not qualified in New Zealand as having any substantive impact on the quality of our service. We are committed to ensuring that we provide high quality, affordable legal services to all our New Zealand clients.

Our legal team have all trained at leading firms, but have left the traditional corporate law world to join us on our mission to create a new and better way of delivering legal services. They have specialist expertise in technology law, intellectual property law, contract drafting and review, corporate law and commercial law.
