Software & ERP design
Your company has outgrown its tools. Let's build the system it needs.
I design custom software around the way your business already works — so decisions stop waiting on you, your team always knows what's next, and growth stops feeling like chaos.
Why this matters
Every business grows in the same order: idea, hustle, momentum.
You build it as fast as you can. And then, sooner or later, a quieter question arrives — do you refine how you work, or let the cracks widen?
Notes scattered across your phone. Figures pieced together in spreadsheets. Approvals chased through WhatsApp and email. The very tools that helped you move quickly in the early days quietly become the thing slowing you down. Past a certain size, good intentions aren't enough — you need a system.
A decade ago, I was standing exactly where you might be now. My business was growing fast, but the processes behind it barely existed.
I tried the big-name CRM and ERP platforms. They were powerful, but none of them fit the way I actually ran things. What I wanted was a tool that made me sharper without forcing me to rebuild my entire way of working around it — and that gave me an edge rather than another monthly bill. It simply didn't exist.
So I built it myself. That first system became the foundation for everything I design today.
Sound familiar?
Wildly different companies, remarkably similar problems.
Whatever the industry, the same friction shows up again and again. You'll probably recognise a few of these.
Documents live in a dozen different places, and nobody's sure which version is the latest.
You can't say, with confidence, how much you're actually making on each project.
Reports and statements mean hours of paperwork instead of a couple of clicks.
Everything funnels through you — the business stalls the moment you step away.
A big off-the-shelf rollout feels like a project you'll never find time for.
Your team starts each day half-guessing what they're meant to be working on.
Hello, this is Jack
Not a reseller. Not a software house. The person who builds it.
I'm Jacek Pluszcz. For more than a decade I've helped companies streamline how they work and designed the custom software that makes it stick.
I don't resell off-the-shelf products, and there's no five-figure fee just to start a conversation. I've run a growing business myself, so I know exactly what it feels like to outgrow your own tools — and I build the systems that fix it.

Where I can help
Software for the parts of the business that keep tripping you up.
Tailored to how you work, built to make the everyday faster. A few of the areas I'm asked about most:
Meeting scheduling
Bookings, site visits and appointments coordinated in one shared, conflict-free place.
Time management
Hours, shifts and availability tracked properly — no spreadsheets, no chat threads.
Budget management
See what every project costs and earns as it happens — not months after the fact.
Whatever you run on
If it's part of your workflow, it can be part of the system. It bends to fit you.
The approach
A clear path from problem to working system.
Process audit
I learn how your company truly runs, day to day, before a single line of code is written.
Building your system
We shape the software around your real workflow — never a generic, one-size template.
Team training
Your people are shown exactly how to use it, so it's adopted from the very first day.
Development & support
The system keeps evolving with you, backed by ongoing development and hands-on support.
A head start
You're not starting from a blank page.
I bring a library of proven, ready-made modules — then adapt and connect them around your business, so you get a tailored system without the wait of building every piece from zero.
Connected, not isolated
We connect the tools you already use.
Your system doesn't sit in a silo. We wire it into your existing apps and data through secure APIs, so information flows in one direction — forward — and your team stops re-typing the same thing twice. See all integrations →
Why work with me
A different kind of software partner.
Built for the UK market
Designed and supported here in Britain, around the way UK companies actually operate.
You own the system, not a subscription
This isn't a rented seat in someone else's SaaS. I implement a system that's genuinely yours.
The person who built it stays with you
You work directly with the one who designed and developed it — from first call to long-term support.

Questions from our clients
Good questions, honest answers.
Yes. Every system I build runs in the browser and adapts to desktops, tablets and phones — so your team can use it on site, on the road, or at their desk, without installing anything.
It depends on scope, but because I start from a library of proven modules rather than a blank page, most projects move quickly. After the initial audit I'll give you a realistic timeline, and we usually get a working first version into your hands early rather than making you wait for everything at once.
In most cases, yes. Systems can connect to the software you already rely on — accounting, email, calendars and more — so the new system fits into your world rather than forcing you to abandon everything overnight.
We bring it with you. Part of the process is carefully migrating and tidying the information you already have — spreadsheets, documents, contacts and history — so you start on day one with everything in one organised place.
Yes. I'm based in London and work with clients worldwide. The work is remote-first by nature, and I'm happy to fit around your time zone for calls and key sessions.
Absolutely. I work to UK GDPR requirements and am happy to put the appropriate data processing agreement in place before any work begins, so you're covered from the start.
Security is built in from the ground up — encrypted connections, role-based access and regular backups — so the right people see the right information, and your data stays protected at every step.
That's expected — businesses move. The system is built to evolve, and I stay on to develop and support it as your priorities shift, rather than handing it over and disappearing.
As many as you need. Because the system is yours rather than a per-seat subscription, you're free to add accounts as your team grows — from three people to a few hundred.
