What’s the problem?
Well, the problem is that sometimes “managed services” is treated as a singular noun phrase, and sometimes it’s treated as a plural noun phrase. I personally think that it could go either way, but that the plural is more graceful: it’s difficult to write “Managed services is a way…” No matter what, however, you’ve got to be consistent.
“Managed services allows” makes it singular.
“Managed services spearheads” makes it singular.
BUT!
“Managed services are” makes it plural.
