Custom Software Development

HR software

The HR software manages the people in the company: who works when, shifts and schedules, leave, documents and who can see what in the system. Salaries and social security contributions remain in the accountant's payroll software, which costs from 12 € per month. A custom HR module makes sense when shift schedules, sites and employees' work need to be in the same system as customers and invoices: 3 000-29 300 € (based on 98 of our quotes as of 14 August 2026). Elite Call Center's ERP has such a module.

What it includes

  • Employees

    Details, position, contract, documents and history for every employee.

  • Shifts and schedules

    Who works when, by team and by site, with shift swaps and approval.

  • Summarized working time

    Worked hours for the period, night work, overtime and public holidays.

  • Leave

    Leave request from a phone, approval and balance by employee.

  • Roles & permissions

    Everyone sees only what their role allows.

  • To the payroll software

    Worked hours and leave are sent to the accountant as a file, with no retyping.

How the process works

  1. 1The manager prepares the monthly shift schedule by site, and employees view it on their phones.
  2. 2The employee requests leave or a shift swap, the manager approves it, and the schedule updates automatically.
  3. 3At the end of the period, worked hours, night and overtime hours, and leave are sent to the accountant's TRZ software.

In brief: salaries stay in the payroll software

Saitami's HR system manages shifts, schedules, leave, attendance and employee documents, and sends payroll-ready data to the accountant. Payroll and declarations to the NRA remain in their payroll software (Plus Minus Payroll from 12 € per month, Biznes Navigator Payroll 249 € one-off).

A custom HR module makes sense for everything else: shift schedules by site, summarized working time, leave, documents and permissions, when people work in shifts, in the field or in a call centre and the schedule is linked to customers, contracts and invoices. The hours are then sent to the payroll software ready to use.

Off-the-shelf programs and their prices

The prices are taken from the manufacturers' websites, checked on 17 October 2026, in euros excluding VAT unless stated otherwise.

A custom HR module from us costs 3 000-29 300 €, based on our quotes, with no per-employee fee; the payroll software remains with the accountant.

What the Labour Code requires from the schedule

The system should calculate these rules, not an employee by hand:

  • Aggregated calculation of working time under Art. 142, para. 2 of the KT: hours are compared for the entire reference period, not for the day, and any excess is overtime.
  • Night work and rest between shifts: the minimum daily and weekly rest periods are checked before the schedule is approved.
  • Paid annual leave: at least 20 working days under Art. 155, para. 4 of the KT, with any unused days tracked by year.
  • The employment contract and the notification to the NRA under Art. 62, para. 3 of the KT remain in the TRZ software; the HR module keeps a copy and tracks the deadlines.
  • Employees' personal data under GDPR: role-based access and an audit log showing who viewed what.

What we have built so far

For Elite Call Center, we built an ERP with HR, scheduling and billing modules connected to the call centre infrastructure: operators, shifts and schedules are in one system together with calls and clients. In the demo for a security company, guards' schedules are organised by site and contract. Our own Saitami ERP system prioritises the team's tasks.

What to check in the demo

Try it with one real month of shifts:

  • How long it takes to prepare the monthly schedule and replace someone at the last minute.
  • Whether the system warns about insufficient rest and overtime.
  • How an employee requests leave from their phone and checks their remaining balance.
  • In what format the hours reach the accountant's TRZ software.
  • The cost over three years with the current number of employees and with twice as many employees.

What we have not done so far

We have not developed payroll and social security contribution calculations, filed declarations with the NRA, or connected a system to time clocks. Payroll remains in the TRZ software; we assess time-clock integration based on the model and include it in the proposal. We track TRZ deadlines for accounting firms in Account-X.

What you gain

One schedule

The team and the manager view the same schedule, including from their phones.

Across the entire system

Staff use the same system as customers, sites and invoices.

No per-employee fee

A new employee does not increase the bill.
