Custom software: contract, ownership and exit
Who owns the data, access credentials, and outputs in the end? The answer to this question says more about a provider than any reference list — and belongs before the signature, not after.
Before commissioning custom software, clarify in writing: data and access belong to the client, in which format and within what timeframe they will be handed over upon termination, what subsequent changes will cost, and that documentation is a quoted line item, not a verbal promise.
01 — Contract
What needs to be clarified in writing
- Ownership of data and access. They belong to the client. If a provider won't clearly confirm this, that's the most important information from the conversation.
- Handover upon termination. In what format, within what timeframe, at what cost.
- No minimum term without consideration. Lock-in is justifiable if something is delivered in return — otherwise not.
- What a later change costs. The total cost isn't determined by the project price, but by the hourly rate in year three.
- Documentation as a deliverable. Not as a promise, but as a line item in the proposal.
02 — Questions
Questions you should ask
- What happens if the project becomes more expensive than estimated — who bears that?
- Who owns data, access, and, if developed, the source code?
- What does operation cost in the second and third year?
- What does the documentation we receive at the end look like?
- How would you measure whether the project was successful?
- Is there a case in which you would advise us against this?
03 — Warning signs
When to be skeptical
- Guaranteed results. Anyone promising top Google ranking or a specific revenue increase is selling something they can't deliver.
- No pushback. A provider who thinks every project is a good idea has either not listened or is only selling.
- Time pressure. Limited-time discounts on project prices are a sales tool, not an offer.
- Unclear ownership. Anyone who won't clearly say who owns data and access doesn't have your interests at heart.
- No contact with technical expertise. If only sales sits in the first meeting, that's where misunderstandings arise.
04 — Questions
Frequently asked questions
Can we start with a spreadsheet?
Often yes, and that's a good test. If the spreadsheet maps the process and only fails due to multi-user capability, permissions, or data volume, the requirement is clear and the project is calculable.
Who owns the source code?
You do, completely, upon payment. That's in the contract. You can take it to any other developer — that's the point.
What if we discover new requirements during development?
That's normal and planned for, because we work in small steps. A new requirement is incorporated into the next step, instead of stalling the entire project.
How do we avoid the project going off the rails?
Small steps with usable results, fixed budgets per step, and the option to exit after each step. Large fixed-price projects over twelve months are the most reliable path to disappointment — for both sides.
When does custom software pay off compared to standard software?
When your process is a genuine competitive advantage, when standard software only fits seventy percent and the rest ends up as manual work, or when license costs per user exceed the development cost over a few years. If it's only about convenience, standard software is cheaper.
How many users can a system like this handle?
That depends on the architecture, which we plan according to your expected growth — from a few users in your own business to several hundred across multiple locations.
What happens if we no longer work together?
You have the code, documentation, and access. We deliberately use widespread technologies so that a switch is possible without someone having to rebuild everything.

Let's talk briefly about whether this makes sense for you.
A twenty-minute conversation is usually enough to clarify whether a project makes sense. If not, we'll say so — that's cheaper for both sides than an offer nobody needs.
