Custom software
Custom software development in Belgium
You run SAP here, Odoo there, Power BI alongside it and ten separate SaaS subscriptions. We replace all of that with one custom platform, built around how you work. It sits in your own repository, is open source and grows in waves, with a go/no-go decision after each wave.
1 platform
instead of separate tools and licences
Day 1

Go/no-go
you decide after each wave whether we continue
What we build for you
No off-the-shelf package that bends your work to the software. We build the modules your work needs, in one coherent platform.
Quotes and CRM
From first contact to signed quote in one flow, with the fields and steps your sales team actually uses.
Stock and item management
Live stock per location, linked to orders and purchasing, without a separate spreadsheet that no one trusts any more.
Orders and planning
Orders, deliveries and planning in the same system, so operations and sales look at the same screen.
Invoicing integration
Invoices that follow automatically from orders and flow neatly into your accounting package, with no double entry.
Portal and dashboards
A customer portal and dashboards that show the figures you steer on, live instead of in a monthly export.

How we work
Start with an audit
In four weeks we map your tools, costs and processes and deliver a signed report with a concrete build plan.
Building in waves
Each wave delivers a working piece of platform you use straight away, not a big bang that only does something after a year.
Go/no-go at every gate
At the end of each wave you decide whether we continue. You are not locked into a path that no longer fits.
In your ownership
The code is open source and sits in your own repository from day one. No per-user licences, no lock-in.
Frequently asked questions
What companies ask us before they start on custom software.
What does custom software cost?
You work with a fixed price per wave, no open end. Each wave has an agreed scope and result, and with a go/no-go you decide whether the next wave starts. That way you know in advance what you pay and what for.
Who owns the code that YK builds?
You do, from day one. The code sits in your own repository and is open source. You do not depend on YK to carry on with it, and there are no per-user licences.
Why custom and not an off-the-shelf package like SAP or Odoo?
An off-the-shelf package forces you to adapt your work to the software and charges per user. Custom software follows your processes and stays yours. We replace the separate tools with one platform instead of adding yet another licence on top.
Ready to build your custom software?
Start with a four-week audit. You get a signed report with a concrete build plan and a fixed price per wave, with no obligation to continue.
