Service Types

We offer services adjusted to your needs. Available options are modulated as much as possible with different services and pricing to fit your needs.

Paper Services

The volume of published scientific work is constantly increasing and the required level of its presentation is rising, making it harder and harder to get a manuscript accepted. Formatting or language issues, incorrectly formatted citations or references, logic or flow mistakes, deficiencies, and ambiguities may be the difference between an accepted and a rejected paper, regardless of its scientific value. In Pefcor, we can help you in every stage of the writing process assuring the professionalism and cohesion of your paper.
