How we solve your challenges

From kick-off call to signed agreement and beyond — the full software development contract, handled by one team.

Developing software can be a tough journey with unforeseen obstacles. Our software development agreement is tailored to your development process – whether you work with fixed milestones or agile development techniques like Scrum.

The outcome of the product can be very valuable – with our proven software development agreement you ensure that rights to code, patents and copyrights are protected as much as you and your business partner agree on. How confidential information is treated during the agreement and after it ends will also be clearly regulated.

Greatly developed software will survive the agreement. If necessary, we help you to cover the transition from the development stage to an ongoing maintenance and support relationship.

All-in-one flat fee package including strategic planning and structure set-up, drafting, and adjustment of your individual software development agreement according to your needs. We start with a joint kick-off call with our licensing legal expert to discuss goals, set-up, and important clauses, then deliver a bespoke agreement with two feedback rounds.

Software development agreement FAQ

The questions founders and tech companies ask us most before we start drafting.

It has to clearly set out the roles and duties of the parties in the development process. The ultimate goal for the software development has to be clear, milestones on the way there and a process for a flexible and legally watertight adjustment of goals.

It is important to agree on fair remuneration for milestones reached within the development process. The software development agreement ensures that this crucial point is clear before starting the project. Furthermore it is highly important to agree on the rights of use of the developed software and parts of it – including whether the developer has interest in exploiting the developed product or parts of it.

Key points include: the term of the project; liability regulations in case something goes wrong; possibilities for termination; minimum standards for the developed product; and the testing process of the product.

You need to know what timeframe you realistically agree on for the development of the software. It is also crucial to leave space for adjustments of the contract, in case you agree to change the route towards your goal.

We agree the scope and price in writing before we start — so you know exactly what you will pay. For open-ended or iterative mandates we can agree pre-paid hours instead. Either way, there are no billable-hour targets or surprise invoices.

This depends entirely on what the agreement says. Without a clear IP clause, ownership may remain with the developer by default. Our agreements explicitly assign — or license — all code, patents and copyrights to the party you agree on, and regulate confidentiality both during and after the engagement.
