The index level can be compared with an upwardly revised 55.9 in October. An index number above 50 indicates increased activity in the sector.
Analysts had expected a rise to 56.0, according to Bloomberg.
"The recovery in the services sector has gained real momentum during the autumn," says Jörgen Kennemar, responsible for the analysis of the purchasing managers' index at Swedbank, in a press release.
The composite index for November, which also includes industry, also rose significantly to 57.8, up from 55.6 in October.
"The economic situation in the business sector has improved significantly during the fourth quarter, but companies are still holding off on hiring new employees. This indicates productivity-driven growth," says Jörgen Kennemar.
