The current economic growth in no way affects the shortening of the payment deadline. The Act of March 8, 2013 on Payment Dates in Commercial Transactions not only adjusted the binding provisions to Directive 2011/7 / EU of the European Parliament and of the Council of February 16, 2011 on combating late payment in commercial transactions, but also to shorten the payment deadlines established by the contractors. The intention of the legislator was to establish, in principle, a deadline of no more than 30 days. In the case of concluding a contract for more than 30 days, the creditor may after the expiry of the period demand interest from the debtor, counted from the day of fulfilling his service and submitting the invoice or invoice to the debtor by the date agreed by the parties. The only exception are healing entities. There was also a distinction between entrepreneurs for whom the payment deadline can not exceed 60 days and public entities - up to 30 days.
