OW Analytics is a modern consulting company created by a leading advisory firm Olesiński i Wspólnicy. OW Analytics is specialized in conducting broadly defined analytical projects. Initially, the leading service provided was performing benchmarking studies for transfer pricing purposes, which originated from new provisions of transfer pricing regulations in Poland, effective January 2017.

With time, our offer has been extended by other services, based on our knowledge and competence in the area of finance, analysis, statistics and accounting. Analytics team’s competences and experience are complementary to those possessed by Olesiński i Wspólnicy, which means that projects are often carried out jointly by both companies.

Effective 2017 the documentation requirements regarding transfer pricing in transactions between related entities have been significantly expanded. In addition to local file documentation prepared in a descriptive form, taxpayers are required to demonstrate that the prices or margins established in intragroup transactions do not differ from the terms agreed in non-controlled transactions. This is achieved by comparability analysis (benchmarking).

Analysis of comparative data is often based on complex financial models that require access to unique financial data and in-depth knowledge of finance, risk assessment, statistics and econometrics. Due to the specificity of transactions, the process of preparing comparative data is usually very complex and involves obtaining financial data on similar transactions, followed by statistical processing of these data, including expert adjustments.
Transfer pricing is subject to increasing interest of tax administrations. Recently the number of tax inspections in this area has grown significantly, and findings of the inspectors question settlements of taxpayers in an increasingly competent and effective manner. This is a global trend and its reversal is not expected. Therefore, it is crucial for enterprises within the capital groups to not only prepare the required tax documentation, but also to set the terms of the transaction between related entities in order to meet the arm's length principle. Using the extensive experience gained in the preparation of benchmarks, OW Analytics experts specialize in creating tools that allow clients to determine the terms of intragroup transactions, such as e.g. loans.
There are a number of cases where it is necessary to determine valuation of an enterprise or part thereof. Such situations occur, among others, when:
- a company is sold or bought, as well as in case of mergers,
- an enterprise is contributed in kind to the acquiring company,
- change of the legal form of an enterprise takes place,
- an organized part is separated, within an existing enterprise, which may then be sold or contributed.

Specialists participated in a number of projects related to the valuation of enterprises and frequently advise clients in this field. In addition, we specialize in advisory related to the accounting for acquisitions and mergers in consolidated financial statements prepared in accordance with IFRS and Polish accounting standards.
An inherent element of investment processes is often search for external funding (e.g. subsidies, loans). In such a case, it is necessary to prepare a business plan which may cover forecast of company's financial results. OW Analytics has extensive experience in modeling business plans, including for start-ups.
Acquisition of an existing enterprise may turn out to be the best way to expand business operations, increase market shares or enter a completely new market. Such a transaction may, however, expose the buyer to many risks resulting from the lack of detailed knowledge about the status of the acquired entity. The process of recognizing risks and calculating their impact on the financial position of the business taken over is a process of due diligence.

OW Analytics conducts financial due diligence, while in the area of legal and tax due diligence, we recommend Olesiński & Wspólnicy. A great advantage of completing the due diligence process to the full extent is not only getting to know the acquired company better, but also obtaining arguments that may be helpful in the purchase negotiations.
Pressure of business environment and increased competitiveness encourage entities to continuously increase effectiveness of their internal processes, which in practice forces them to improve their efficiency. Constantly changing regulatory environment results in the necessity to implement tailored IT solutions aimed at automation of important business processes and reduction of compliance risk.

The combination of expert knowledge of Olesiński & Partners advisors and many years of business experience allows OW Analytics to create IT tools tailored to the individual needs of customers, taking into account the specificity of their business and at the same time providing them with a competitive advantage in terms of the improvements achieved as a result of the implementation of organizational improvements.

The IT tools that we have developed include, among others:
- MDRnow - a tool comprehensively supporting risk management and reporting related to the requirements of MDR regulations;
- A tool to implement financial reporting compliant with International Financial Reporting Standard 16;
- Intra-group guarantee pricing model.
It is not rare in implementations of ERP systems in Poland that the system does not meet some requirements of tax laws, the Accounting Act or other legal acts. This usually results from the high pace of system implementation. The final, negative effect for the Polish subsidiary may be the system's non-compliance with law (e.g. invoices generated in the system do not meet requirements of tax law) or non-functionality (e.g. lack of ability to generate tax filings out of the ERP system). Therefore, it is important that local legal requirements are taken into account when implementing the ERP system. OW Analytics, with practical knowledge and experience gained during the implementation of ERP systems, offers assistance in implementation or post-implementation audit, the aim of which is to detect as soon as possible problems that may result in a lack of compliance with legal requirements.
Advisors of Olesiński & Wspólnicy and OW Analytics work for several companies listed on the Warsaw Stock Exchange in the legal, tax and economic areas. The experience gained helps us to successfully advise, among others in the following areas:
- Market Abuse Regulations,
- non-financial reporting,
- periodic reporting - support of issuers in fulfilling their duties.
