Re-invoicing consists of reselling goods or services to another company at the same price, without charging any commission or margin. Usually, all costs are then transferred to the company that actually uses the service or good to which the re-invoice relates. It is much more common to re-invoice a service than to purchase goods.

When a company is declared bankrupt, the employer, i.e. the payer of contributions, is obliged to deregister all employees from social insurance and health insurance with the Social Insurance Institution (ZUS ZWUA form is used for this purpose).

The whole process of declaring bankruptcy of a company is counted from the moment of the decision on filing the petition to declare bankruptcy until the moment of concluding the agreement and lasts about 6 months. The condition for the bankruptcy process is the positive consideration of the petition by the court and the consent of 2/3 of the creditors.
