Delays in payments to Polish companies have fallen to a nine-year low amid record economic growth, according to a report.

Polish firms have long complained about the time lag before they are paid for their work.

But in the final quarter of last year such delays fell to the lowest level in nine years as bills were settled more quickly, according to a survey by the National Debt Register (KRD) of the Economic Information Bureau and the Conference of Financial Companies in Poland.

The Polish economy grew 5.1 percent in the final quarter of 2017, the country’s Central Statistical Office (GUS) said earlier this month in a flash estimate that pointed to the best result in almost ten years.

The Economic Information Bureau is a private company which provides information about overdue debt owed by individuals and companies.
