A5 Personnel and A5 Payroll: Replacing 1C, BAS and Parus with Ukrainian software
The risks of Russian software in wartime and the transition to InBase’s Ukrainian HR and payroll software.
During Russia’s full-scale war against Ukraine, using Russian software at Ukrainian businesses and public institutions has political, economic and security consequences. HR and payroll systems are particularly sensitive. They hold employees’ personal data, details about the organisation’s structure and payment information. A leak can put people at risk, while altered or lost records can disrupt payroll and reporting. [Explanation from Ukraine’s State Service of Special Communications](https://cip.gov.ua/ua/news/posilennya-zakhistu-derzhavi-derzhspeczv-yazku-oprilyudnila-perelik-zaboronenogo-programnogo-zabezpechennya-ta-obladnannya).
## Software updates and the economics of war
An organisation depends on whoever fixes vulnerabilities, updates payroll rules and adapts reporting forms. If the supplier ends support, the organisation may be left with unpatched vulnerabilities and outdated accounting settings. Installing updates from a source the organisation cannot trust also introduces risk. Among its cybersecurity measures, the National Bank of Ukraine recommended avoiding updates to software of Russian and Belarusian origin. [National Bank of Ukraine recommendations](https://nasu.com.ua/wp-content/uploads/2025/10/5283.pdf).
When payments for licences or support ultimately reach a Russian rights holder through intermediaries, the Ukrainian customer supports that business. Taxes on that income may contribute to the state budget Russia uses to finance its war against Ukraine. Procurement teams should establish who controls the product, who releases updates and who ultimately receives payment.
## Ukrainian alternatives are available
For a long time, many Ukrainian businesses lacked a practical alternative to the familiar HR and payroll modules in 1C, BAS and Parus. Over years of use, those systems accumulated personnel files, payroll histories and settings tailored to each organisation. Switching required a product that met Ukrainian accounting needs and a team that could migrate the data and connect the new software to other systems.
Businesses now have that choice, thanks in part to Software Ukraine member companies that develop and implement Ukrainian software. Some of these products are listed in the [Software Ukraine guide to alternatives](https://ua.software/navigator/).
Today I’d like to introduce two InBase products, **A5 Personnel and A5 Payroll**. Together, they cover personnel administration, electronic HR documents and payroll. Both run in a web environment on Ukraine’s UnityBase platform. [InBase product overview](https://inbase.com.ua/rishennya-upravlinnya-personalom-ta-zarplata/).
## From HR records to payroll
In **A5 Personnel**, the HR team maintains the organisational structure and staffing plan, issues personnel orders, manages electronic personnel files and tracks working time. The system also includes an employee portal and tools for performance reviews and staff development.
In **A5 Payroll**, accountants use HR records to calculate and recalculate pay, track it by funding source, and prepare accounting entries and statutory reports. [Features of both modules](https://inbase.com.ua/rishennya-upravlinnya-personalom-ta-zarplata/).
Consider an employee who transfers to another position in the middle of the month. HR issues the order and records the effective date. During implementation, the team should check that the payroll calculation takes account of that date and the pay terms for both positions.
## Preparing for the transition
I recommend starting with an inventory of the data and rules behind each monthly payroll run. HR and accounting should agree which reference data, personnel files and payroll records to migrate, which can stay in the archive, and which systems need to exchange data.
Before going live, **run payroll in parallel** in the old and new systems for the same period. Compare net pay, deductions, accounting entries and reports. Check holiday pay, sick pay and prior-period adjustments separately. Investigate differences before launch. A discrepancy may come from a migration error, a difference in configuration or a correction to a rule that was previously applied incorrectly.
## Implementation partner
**IQusion IT LLC is an InBase partner, a member of Intecracy Group and an official integrator for A5 Personnel and A5 Payroll.** We implement both products and support customers from migration planning and integration setup through the first month-end close in the new system.
If your business or institution plans to replace the HR and payroll modules in 1C, BAS or Parus, contact IQusion IT to scope the work and plan the transition.
