It is important that you have both English editing as well as manuscript writing services. However, there is not always room for both the services, depending on whether you have the time to do the work or not. You should, therefore, consider debating whether there is room for both in your company.
Editing takes a look at how materials are presented. The main focus of editing is to make materials understandable, better organized, and more suitable for the audiences. Since editing is an essential part of formulating a research argument, it occurs several times throughout the process. On the other hand, you need to take a deeper look at the way in which the ideas are presented.
Manuscript proofreading focuses on correcting errors in spelling, grammar, etc. that are superficial by nature. It, therefore, occurs normally at the end of the process of writing. Researchers are often of the opinion that they need only proofreading to finalize the articles before they are submitted.
Which one is needed?
Even though researchers may believe that proofreading itself is enough to finalize the articles before submission, it is actually not enough and, therefore, it is necessary for a company to provide manuscript services. An editor that understands your field of work can provide a better feedback. Submitting a paper, which is error-free is not only important, but it is also necessary to keep up the quality of the manuscripts or papers. It will also make the paper or manuscript more understandable to its readers. With proofreading alone, you would end up missing the constructive criticism that is needed to make a difference to your manuscript and to make it get accepted by the publishers. You would, therefore, need to provide both the services to your clients rather than just one of them.
