Custom-built software for your business
When spreadsheets no longer cut it and no off-the-shelf system fits, I build software shaped around your process — with your business rules built in.
Custom-built software is made for the way your business actually works — not your business contorting itself to fit a generic product. I design and build the system from your process: management, inventory, financials, dashboards. I start where it hurts most, deliver in increments, and evolve it based on real use.
When spreadsheets start holding your business back
Every business starts managing everything in spreadsheets — and for a good while it works. Then the problems show up quietly: two people need to edit at the same time, a formula error slips through and turns into a loss, the same data gets typed in three different places, and pulling a simple report becomes an afternoon of manual work.
When your most important process depends on a fragile file that only one person understands, it has stopped being economical and become a liability. That is when custom-built software pays off — not to "digitise everything," but to move the critical process off a spreadsheet and into a reliable place. If you are wrestling with that exact question, I break down the signals in spreadsheet or system: when to switch.
What custom-built software solves
Custom management
A system that runs your business your way: records, workflows, and screens that reflect how you actually operate.
Inventory control
Stock in, stock out, cost and margin per item — with your business rules, not those of a generic store.
Financials and billing
Accounts payable and receivable, automated billing, and month-end closing without a parallel spreadsheet on the side.
Dashboards and reports
The numbers that matter, updated automatically — decisions based on reliable data, not guesswork.
Client portal
A space where your clients track orders, status, or documents — fewer emails and calls for your team.
System integrations
Your ERP, e-commerce, spreadsheets, and tools all talking to each other — data entered once, flowing everywhere.
Off-the-shelf or custom-built?
A fair question: why not just buy something ready-made? Almost always that is the right call for what every business does the same way — invoicing, payroll, accounting. There is no point reinventing that.
Custom-built pays off for what is your differentiator: the process you handle differently and that no off-the-shelf product covers without workarounds, the point where the sum of monthly fees has exceeded the cost of owning your own, or when your data is locked in tools that do not talk to each other. In practice, the best setup is usually hybrid — off-the-shelf for the standard stuff, custom-built for the core. I help you decide case by case in off-the-shelf or custom-built software.
How I build your system
Assessment
We talk through the process that causes the most friction. I understand how it works today and calculate the return on turning it into a system — before you spend a cent.
Fixed scope and MVP
We define the highest-return piece to start with, I design the screens, and send you a fixed quote (agreed upfront). No surprises along the way.
Built in increments
I develop the system fitted to your process and deliver it in parts, so you can use it and see value early — not just at the end.
Delivery and evolution
I go live, train the team, and stay close to adjust and evolve as real use unfolds. A system nobody uses solves nothing.
Not just theory
I build real software — I do not resell tools. These are custom-built systems I delivered for very different niches, each speaking the language of that business:
What it costs
There is no fixed price list: a lean system that solves one process costs far less than a full platform. What I guarantee is predictability — a fixed quote (agreed upfront) before any work starts, delivered in increments, starting with the piece that returns the most. If you want to understand what drives the price of a system, I wrote a straightforward guide on that.
Frequently asked questions
What is custom-built software?
It is software developed around your company's process, with your business rules built in — instead of you adapting your routines to a generic product. It can be lean (solving one process) or comprehensive: the scope matches your problem, not a fixed package.
What is the difference between custom-built software and an off-the-shelf system (ERP/SaaS)?
Off-the-shelf serves thousands of companies with the same code — it is quick and cheap to get started, and you adapt to it. Custom-built is made for you, fits your process exactly, and carries no license subscription. Standard tasks (invoicing, payroll) make sense off-the-shelf; your differentiator makes sense custom-built — and often the best answer is combining both.
Is it worth it for a small company?
It usually is when the process is central, high-volume, and follows rules that no off-the-shelf product handles without workarounds. If it is a standard or low-volume process, I will be the first to tell you to stick with an existing product or a spreadsheet — and I say that before you spend anything.
How long does development take?
A lean system (an MVP for one process) typically goes live within a few weeks. Larger systems take longer, but I always deliver in increments, starting with what returns value the fastest — so you see results early, not just at the end.
Do I need to throw away what I already use (spreadsheets, ERP)?
No. In most cases the custom-built system coexists with what you already have — it pulls data from your spreadsheet, integrates with your ERP or e-commerce. The migration is gradual, starting with the most critical process first.
How does it start and what does it cost?
It starts with a free assessment: you walk me through the process and I tell you what is worth building, what is worth buying off-the-shelf, and the expected return. The price depends on the scope — you receive a fixed quote (agreed upfront) before any work begins.
