We work as a team and treat each task as a project. Each project team involves several experts, which means that our Clients can discuss their problem at all times, even when one of the team members involved in the project is out of office.

Well qualified accountants who work in our locations in Katowice and Warsaw have the benefit of the ongoing support from a tax advisor and expert auditor. We are mobile and flexible – we can also work at the Client’s premises.

Top quality and the highest level of our services helped us win the ‘Accounting Leader’ competition held every year in Poland; the aim of the competition is to select the best accounting professionals and showcase modern accounting departments and accounting offices.

Tax advice service holds a special place at GLC.
Our team of attorneys, legal advisors and tax advisors work in synergy, combining professional experience with thorough knowledge of the economy and excellent understanding of the clients’ needs – all that translates to providing comprehensive legal and tax advice in all areas. Our experience in tax law covers all aspects of transfer prices, compliance and support of fiscal and administrative court proceedings.

Our experienced tax advisors act in the taxpayers’ best interest; we defend taxpayers’ rights and look after security of their business. We relieve the clients of the burden of day-to-day complicated tasks related to running a business. We help entrepreneurs operate in the climate of unclear, constantly changing tax regulations, inconsistent interpretations and assist when the tax authorities’ interpretation is not favourable for the taxpayer.

GLC also specializes in corporate law.
We have comprehensive specialist knowledge of the operating mechanisms and the processes within companies; each case is treated as a unique project delivered by a team of experts supervised by one of the Partners.

We provide legal services to Polish and foreign business entities. We support our clients in the area of commercial and economic law, with particular emphasis on company law, mergers and acquisitions, intellectual property law, banking and financial law, new technologies law, payment services, anti-money laundering, data protection, antitrust law and prevention of unfair competition. Our law department provides ongoing legal support to start-ups and in the e-commerce sector.

Law, taxes and accounting are disciplines where constant professional development is fundamental. Regulations tend to change and often are open to inconsistent interpretations, which necessitates regular participation in trainings, courses, conferences and other forms of professional development.

One of GLC’s priorities is to recruit highly qualified and competent team members, and provide the team with the opportunities for professional development.

Our team members are degree-educated professionals, holding additional professional qualifications (e.g. lawyer, tax advisor, certified accountant) and they constantly improve their competences participating in specialized trainings.

The quality and timeliness of our services, as well as our client’s data confidentiality, is enhanced by implementing the quality standards ISO 9001/2008, ISO 27001/2013. We hold professional liability insurance at the level which significantly exceeds the statutory requirements and is at the maximum possible.

The form of contacts with clients depends on their preference.
We are available for meetings at GLC locations or at customer’s premises, face-to-face, via videoconference, e-mail or telephone. We offer our clients access to convenient computer applications which enable them to track the work progress, view reports and data, obtain information on matters of interest, commission new tasks, or simply as a means of communication.

We focus on new technologies – our competence in the field of accounting systems are far above the standard level. A few examples of the systems we work with are: SAP, Enova, Comarch CDN Optima, Microsoft Dynamics Navision, Microsoft Dynamics AX (AXAPTA), Rewizor, Symfonia and BPSC, in Polish, English and German.

The GLC team has extensive experience in implementation of Enova365, as well as running reports, analysis and listings, and creation of additions and extensions tailored to work with other applications used by the client.
