A well-drafted software development agreement is critical when you’re commissioning bespoke software, whether you’re rolling out a complex CRM system across a growing business or building a platform as the core of a new product offering.

The right software can bring efficiency, innovation, and a competitive edge, but it also carries legal and operational risks. You may face challenges such as unclear timelines, changing requirements, or disputes regarding deliverables and ownership.

Unlike standard IT contracts, a custom build needs a legal agreement that reflects the unique features of your project, from your chosen development methodology to how and when the software will be tested and delivered. And it’s just as important to understand the developer’s position: reviewing the project from the supplier’s angle can help you anticipate risks and align expectations early on.

For that, it’s worth considering our insights on software development contracts from the developer’s perspective .

Getting this right from the outset helps avoid costly delays and mismatched assumptions. If you’re unsure how to structure your contract or need support negotiating with your supplier, our commercial law solicitors can help you create a robust agreement that supports your goals and protects your investment.

Custom software development contracts are critical when you instruct a supplier to develop bespoke software tailored to your specific needs.

Unlike other less tailored IT contracts (such as licences for off-the-shelf software), you’ll need robust software development contracts to address detailed development terms and lay out key niche provisions, such as the deliverables and how the development process will work in practice. These contracts can often involve significant negotiation with developers, especially where the technology is business-critical.

Software projects are each unique, so contracts don’t follow a one-size-fits-all approach.

The development methodology (whether Waterfall, Agile, or a mix) will shape the agreement and determine what it needs to include.

• Waterfall typically follows a structured, step-by-step process. Each phase usually needs to conclude before the next one begins.
• Agile takes a more flexible approach, where the overall scope and goals are set at the start. Still, the details evolve as the project progresses, meaning there’s more room to adjust priorities during development. Agile can come with more uncertainty and risks, making strong contractual protection all the more important.

Your agreement should clearly outline the development methodology to prevent misunderstandings about what, when, and how your software will be developed.

Some key differences include:

• Waterfall
  :
  Requires the supplier to deliver specific features by fixed dates, with binding acceptance criteria.
• Agile
  :
  Involves ongoing testing during sprints and relies on collaboration, requiring tailored drafting for the development process.
• Waterfall often employs formal change control processes, whereas Agile allows changes to be made naturally within your product backlog.
• Agile projects may include roles such as a ‘Product Owner’ or ‘Agile Coach’ and methodologies like SCRUM or Kanban.

A mismatch between the methodology and the contract can lead to misunderstandings and disputes. For example, an Agile project with a rigid Waterfall contract can result in significant issues. Ensuring your contract accurately reflects the chosen methodology from the outset is crucial.

Your contract should clearly outline how the project will operate and define specific terms for deliverables, timelines, acceptance, and responsibilities.

Your software development agreement should reflect whether your project will follow a Waterfall, Agile or hybrid model, as each comes with its contractual risks and drafting priorities. Terms will differ based on the…
