A small studio that does the whole job.
Most software projects fail in the gap between what the business needs and what the developers build. We close that gap by doing both.
One team. No handoffs.
We do the business analysis and build the software. No translating your needs through three layers of consultants before code gets written.
Working software in weeks, not quarters.
While most vendors are still onboarding, you'll have a functional prototype in your hands — something you can click, test, and shape.
Built to last, ready for what's next.
Clean architecture, modern APIs, and an eye on AI from day one. Your software grows with you instead of becoming next year's legacy system.
Sound familiar?
If any of these hit close to home, you're not alone — and you don't need a bigger tool. You need software that fits.
- Your team is drowning in spreadsheets that were supposed to be temporary.
- You bought a SaaS tool, but half your workflow happens outside of it.
- Reporting takes days that should take minutes.
- You've been quoted six months and six figures for something that should be simpler.
- You need software that fits how you work — not how a vendor decided to build it.
That's where we come in.
Software shaped around real-world outcomes.
We're not a service catalogue. We're a team that figures out what you need and ships it. Here's the kind of work we tend to do.
Internal tools that replace spreadsheets
Custom dashboards and workflow apps that fit your processes exactly — and that your team will actually use.
Reporting & data platforms
Pull data from your existing systems into one place, with dashboards stakeholders and donors can actually understand.
Customer & supplier portals
Self-service portals that cut down on email back-and-forth and give partners a clear, branded experience.
Operational systems
Order management, inventory, scheduling, traceability — the unglamorous software that runs your business.
Integrations & automations
Connect the systems you already use, so data flows automatically and your team stops copy-pasting.
AI-powered tools
Practical AI built into your workflows — drafting reports, summarising data, finding patterns — where it actually saves time.
How traditional vendors work — and how we don't.
Traditional vendor
Klijn Software
- 3 months of requirements before codeWorking prototype in 2–4 weeks
- Business analyst → architect → developerOne senior team, end to end
- 80-page spec nobody readsReal software your team actually tests
- Project ends, vendor disappearsWe stay involved for the long haul
- “AI roadmap” slide deckAI built in where it actually helps
From first call to working software — in three steps.
We resist the urge to plan everything before writing any code. Most of what you'll learn about the software, you'll learn by using it.
- 01Week 1
Discover
We sit down with the people doing the actual work. We map the workflow as it is, find where the pain really lives, and agree on what's worth building first. No 80-page spec — a short, sharp plan you can read in ten minutes.
- 02Weeks 2–4
Prototype
You get working software in your hands — not slides, not wireframes. We build the core flow end-to-end, you and your team use it, and we shape it together. By the end of week four you know exactly what you're getting.
- 03From there
Build & evolve
We harden, extend, and integrate — at your pace. Roll out to more users, connect more systems, layer in AI where it earns its keep. We stay involved for the long haul, because software you'll depend on isn't a one-off project.
Real workflows, not demo apps.
We work best with teams that have real complexity. Two sectors we know inside out:
About
I started Klijn Software because the gap between business and code keeps killing good projects.
I'm Niels Klijn. I've spent years building and running a healthcare platform used across Africa — software that has to work in low-bandwidth villages, satisfy donor reporting, and stay reliable for years.
I do both sides of the work: business analysis and engineering. When the job is bigger than one person, I bring in a small network of senior specialists I've worked with for years. No juniors learning on your project, no outsourced black boxes.
What does this cost?
Custom software pricing depends on scope, but here's the honest shape of it — so you know roughly what to budget before we ever talk.
Discovery sprint
Most engagements start here. We map your processes, identify what to build first, and give you a clear plan and price for the rest.
Full build
Typical range for a custom application or platform, with ongoing partnerships from there.
NGO & social impact
We work with donor cycles and can structure engagements around them. Ask us — we've done this for years.
No surprise invoices. We agree on scope before we start, and if scope changes mid-build we talk about it before any extra work happens.
