Oleksandr Koinov
CEO & Owner
«As a colleague, manager and owner, I understand your accounting pains — I worked as a chief accountant and CFO, and now I am a business owner and manager myself.»
The Ukrainian member of UHY International, a network with offices in 90+ countries — audit, accounting outsourcing, payroll and legal support. 70+ specialists.

During the war we feel especially how important it is to have people around who will listen, understand the circumstances and support you at a difficult moment. We try to keep that attitude in our daily work: to speak openly, look for a way out of difficulties together, support one another and find the strength to keep moving. This is the space we build together with you.
When you come to UHY Prostir, you meet people for many of whom this company was their first job. Here they learned the profession and grew into project managers and heads of practice — some of them into partners. You, our clients, became part of that growth: your trust, the tasks you gave us and the solutions we found together. Behind each of us, in the team and among our clients, there are our own plans, close people and responsibility to them.
We want to spend more time on what really matters to you: understanding your situation, analysis and finding solutions. That is why we keep automating routine tasks, freeing up time for work in which human knowledge, experience and attention bring the most value — to you and to us.
Meet the people of UHY Prostir. Managers, accountants, auditors and lawyers on their work, clients’ tasks and what inspires them.

CEO & Owner
«As a colleague, manager and owner, I understand your accounting pains — I worked as a chief accountant and CFO, and now I am a business owner and manager myself.»

Head of Audit Department
«Satisfying all of a client’s wishes while strictly following tax, accounting and other legal requirements is quite a quest.»

Chief Operation Officer (COO)
«Behind every successful project there are clear processes, a strong team and the right coordination.»

Project Manager
«Being a manager of non-standard projects means always staying sharp. Discussing payroll with a client in an informal setting on a Friday evening — that’s my thing.»

Chief Innovation Officer (CIO)
«I help turn complex internal processes into clear digital solutions — from automating routine operations to introducing AI tools that save the team time and improve the quality of service our clients receive.»

Tax & Accounting Advisory Lead
«An internal auditor from a foreign founding company visited our client. He spoke only English; we understood each other and resolved every question.»
No. Since 19 July 2022 the obligation to pay mobilised employees their average salary has been abolished (Law No. 2352-IX): no salary is accrued, as the employee does not actually perform their duties. At the same time, their job and position are retained (Art. 119 of the Labour Code).
Yes. Non-profit status does not automatically exempt from VAT: for example, when purchasing services from non-residents the place of supply is Ukraine, and such transactions are subject to VAT. NGOs should analyse specific transactions rather than rely on their status alone.
If UHY Prostir keeps your books under a comprehensive service agreement, we bear contractual liability for the result: professional liability is insured for UAH 10 million, so the financial consequences of an error are covered by insurance, not by the client’s budget.
As a general rule — yes, but martial law added an exception: an employee may resign without the two-week notice period if there is a risk to their life or health. In other cases the standard procedure applies, with proper paperwork and full settlement on the last working day.
