Custom Software
Custom business software built around your operation
Sendoris designs and builds internal platforms, client portals and integrations shaped around how your business actually works. You own what we build, and we stay responsible for it after launch.
When off-the-shelf tools force your company to work in someone else's model, the cost is paid quietly, every day, by your team. Custom software is worth it when your core process is genuinely yours.
Availability
Available internationally, with most clients in the Netherlands, the rest of Europe and the United States.
Problems this solves
- Your core process does not fit any product on the market.
- You pay for several tools that each solve part of one problem.
- Important information lives in spreadsheets that only one person understands.
- Software costs rise every year while the fit gets worse.
Who this is for
- Companies whose way of working is a genuine competitive advantage.
- Owners who want to own their systems rather than rent them indefinitely.
- Teams outgrowing spreadsheets but not ready for enterprise software.
Typical use cases
Internal platforms
One operational system that replaces the patchwork of spreadsheets and disconnected tools.
Client portals
A calm, secure place where your clients see exactly what they need and nothing more.
Integrations
Existing systems connected so data stays consistent and nobody retypes anything.
AI-enabled internal tools
Software with intelligence built in where it helps, with a person still accountable for the outcome.
How we work
Define what must be true
We write down what the software has to make possible in eighteen months, before any design starts.
Design the smallest useful version
Fewer features, chosen deliberately, so the first release is in use quickly.
Build and test with your team
Short cycles with the people who will use it, so surprises appear early instead of at launch.
Maintain and improve
We stay responsible after launch. Software is a relationship, not a delivery.
What you can expect
- A system that matches the way your business really runs.
- Fewer subscriptions that each cover part of one problem.
- Information in one place, with a clear owner.
- Full ownership of the software and its data.
Frequently asked questions
- When is custom software cheaper than SaaS?
- Usually when several subscriptions overlap, when a core process does not fit any product, or when manual workarounds cost more each year than maintaining a system would.
- How much does custom software cost?
- It depends entirely on scope, so we give a written estimate after the first sessions rather than a number on a web page. We will also say when the honest answer is to buy something instead.
- Do we own the code?
- Yes. What we build for you belongs to you, including the code and the data.
- What happens if we stop working together?
- You keep the system, the code and the documentation, and we help hand it over to whoever maintains it next.
