Drogowe Centrum Produkcyjno-Handlowe „BIG" Sp. z o.o.

Communication is very efficient, and thanks to our professional and experienced staff, all formalities are completed efficiently and on time. TaxCoach handles our income tax, VAT, and VAT OSS calculations, and also handles HR and payroll for our employees.

This year, the TaxCoach accounting firm implemented a new chart of accounts in our books. This chart was prepared by our management for cost budgeting purposes and adapted to the specific nature of our business. Thanks to the rapid implementation of this expanded chart of accounts, we have better control over our company's financial plan and can easily obtain not only essential tax information but also valuable management information.

We have been working with TaxCoach for almost two years now and we are very satisfied – primarily because their service takes into account the realities of running a business, and not just adapts to accounting regulations.

We feel that there is a company on the other side, and not an extension of the tax office :)
