The story

Started in payroll administration, stayed in the code

LK Software has existed since 2021. Shortly after, I built my first tools at a payroll service provider: API integrations, document conversion and checks on the payroll administration. That is where I learned what a rounding error in a daily wage means for the person receiving the payslip, and how much manual work there still is in the average bookkeeping firm.

Today more than 100 companies work with software we built. For an accountancy software vendor I delivered the integrations with Silverfin, Visionplanner and FiscaalGemak and Microsoft Single Sign-On. That combination of daily experience with production systems and the payroll and accountancy practice is exactly what I bring to every assignment.

I work with TypeScript, C#, Python and Java, on Azure and Google Cloud, with PostgreSQL and automated CI/CD. For larger projects I work with a permanent network of mid-level and senior developers and with payroll and HR experts who have been in the field for more than ten years. But it always starts with the process, not with the technology.

How we work

Three principles

Accuracy over speed

In payroll, "almost right" is wrong. Everything is tested against real data and documented before it goes live.

No black box

You get the code, the documentation and the explanation. What we build is yours and keeps working without us.

Short lines

You talk directly to the person who builds. No account manager, no ticket system between you and the solution.

Our network

Who works on projects with us

Alongside Lars, LK Software works with a permanent network of freelance developers and payroll experts. For each project we put together the team that fits the assignment. LK Software always remains the point of contact and responsible for the result.
