What does custom software cost? Factors, process, and funding options
There's no credible flat rate for custom software — the projects behind them vary too widely. What actually drives the effort, how you get a concrete quote, and which subsidies are available in Austria.
A flat rate for custom software cannot credibly be quoted — it depends on the scope of the project, not the provider. Typical starting point for a first usable version. The actual proposal comes only after a short, non-binding initial conversation.
01 — Price
What it costs
- Price
- Individual based on effort
- Typical duration
- from 8 weeks to the first version
Typical starting point for a first usable version. A fixed price can only be quoted seriously after the initial meeting — send us a brief description of your project, and we'll send a proposal that fits the scope and effort.
02 — Factors
What drives the price
- Scope and number of integrations. Every additional system that needs to participate costs effort — regardless of how simple the core is.
- State of your starting point. Clean data, existing content and documented processes significantly reduce effort. Chaos is the most expensive cost factor.
- How much new material needs to be created. What you can contribute doesn't need to be invented by anyone. This is the biggest lever you have in your own hands.
- Requirements for design and customization. A solid standard system costs a fraction of a custom solution — and is sufficient more often than vendors admit.
- Operating model. One-time project costs or ongoing support: calculated over three years, this often gives a different picture than the quote comparison.
03 — Funding
Subsidies in Austria
For digitalization projects, there are several funding programs in Austria, such as KMU.DIGITAL or the aws digitalization funding. Whether and to what extent one of these is currently relevant for your project, we'll review with you individually. Current conditions: kmudigital.at, aws.at.
Which program is relevant, how high the subsidy currently is, and whether the budget for the current funding period is still open changes regularly — plus there are regional funding programs that vary by federal state. Only the information from the funding agencies themselves is reliable, not a fixed percentage stated here.
The most common mistake is always the same: commission first, then want funding. That doesn't work. Allow several weeks of lead time for application and approval.
04 — Scope
What's included
- Requirements gathering with the people who will be working with it
- Implementation in small, usable steps instead of as a large-scale project
- Migration of existing data from spreadsheets and legacy systems
- Roles and permissions, logging, and backup from the start
- Integration with your existing systems instead of creating another silo
- Documentation and source code that belongs to you
05 — Questions
Frequently asked questions
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.
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.
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.
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.
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 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.
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.
06 — Error
The most common mistakes
- Starting too big. Projects where nobody can use anything for months fail more often than average. A small, usable first step is almost always the better way.
- Not involving the people who work with it. Requirements that only come from management rarely match the actual work.
- Not defining a success measure. Without a metric defined in advance, you can't say afterwards whether it delivered anything — and the next decision will be made on gut feeling again.
- Overlooking operating costs. The project price is only part of it. What operation costs over three years belongs in the same calculation.
- Creating dependency. If you don't get access, documentation and source code, you're locked in. That needs to be clarified before commissioning, not after.

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.
