Swiss businesses tend to pay bills among business partners on time, most of the time.

But a study from financial information firm Dun & Bradstreet showed 42 percent of inter-business bills were not paid on time, clearing an average 10.3 days late.

The worst when it comes to paying on time were businesses in Ticino, where two thirds of bills were paid an average of two weeks late last year.

The best businesses for paying on time were in Appenzell Innerrhodes, where they were 0.1 days early.
