Custom software development
A payroll and HR system built for you
An organisation of over 500 employees runs on a payroll and HR system we built. It is not a product we resell. We can build you one.
Back to custom software developmentWhat is in scope
- Where the HR and payroll numbers come from, and who is retyping them today.
- Separating the payroll logic so a rule change does not touch the whole system.
- Records for employees and their contracts, plus attendance and absence.
- Payroll calculation against your own rules, with output for accounting.
- Roles and access rights, because not everyone may see payroll data.
- At handover you get the source code and the documentation, access included.

45 €/h + VAT
We start with a bounded first stage. We analyse your payroll rules and propose an architecture, against an agreed ceiling.
This is a bespoke build, not a licence. The first stage ends with a decision you can actually make, which is build your own or stay where you are.
Why this tends to be bespoke
Pay transparency reporting lands in 2026. It wants figures that hold up across roles and people, which is where an off-the-shelf system usually stops bending.
What we build on
We do not start from nothing when a proven base exists.
- The open Horilla HR base, extended with your processes
- A separated payroll engine for Slovak rules
- Roles and access rights over sensitive payroll data
- A connection to the accounting system you already run
Proof
On the open Horilla base we extended HR workflows and split out a Slovak payroll engine for an organisation of over 500 employees.
Open the case studyWhat people ask
- Do you sell a finished payroll system?
- No. It is a bespoke build. We have built one and can build another, but there is no product licence at the end of it.
- Who owns the source code?
- You do. When the stage ends you get the code and the documentation, plus every credential, and we keep nothing.
- Who tracks rule changes?
- We agree that before we start. The payroll logic is separated precisely so a change can be made without touching the rest.
- How many employees does this make sense for?
- The system we built runs for over 500 employees. For smaller companies an off-the-shelf product is usually cheaper, and we will say so.
