The figures showed the biggest gap was in the health and other community services sector, where Scotland scored 59 while England and Wales had a rating of 54.
David Knowles, business development director at Creditsafe, said: "There is a lot of debate at the moment as to whether an independent Scotland would be good for its businesses or not.
"This research shows that Scottish companies, on the whole, have a higher level of creditworthiness and have a lower chance of entering insolvency than their counterparts in England and Wales.
"However, this does not necessarily mean Scottish companies would be better off going it alone. There is a huge amount of inter-connectivity between companies all across the UK."
