Declarena Sp. z o.o. was established in 2016 on the basis of the experience of the Welten Biuro Rachunkowo-Księgowe Dorota Welten, founded in 2005. Both companies are professional accounting offices and offer the full range of accounting and personnel services. As a registered accountant, we review and analyse our clients’ bookkeeping, as well as providing advice regarding taxes and how to optimise the bookkeeping procedures within their companies. We invite you to our offices in Poznań and Przeźmierowo.
