I surfed the internet and found both terms, but I couldn’t figure out which one is more suitable in the following context:
Consider that company A persuades company C to buy some product from company B. Now, company A would invoice company B for its services.
How should it be written on the invoice: services marketing or marketing services?
I guess "marketing services", but I’m not hundred-percent sure, and wonder whether both terms can be used in this context.
