When you hire a resume writing service, they do not automatically include a cover letter for your resume. It is typically up to you to craft your own cover letter(s) for use with your resume. However, this may not be your best move and here are some of the reasons why:

Different style of writing

If you have had your resume written by a professional resume writing service and you try to craft your own cover letters to go with them, you may be giving yourself away. Since resume writing services have professionals on board, they understand how to craft a resume that will “sell” your service to a potential employer. This should carry over to your cover letters so that the “tone” is the same.

Paper weight/Color/Etc.

If you have elected to have a resume writing service provide you with hard copies of your resume, then chances are that they are going to use a specific type of paper and ink on the resume. If you put together your cover letter and it is on a different type of paper and different ink tones, then you could be “outing” yourself. It is practical to have your resume and your cover letter paper match.

Strengths and Weaknesses

Since your cover letter is your first impression with a potential employer, and what makes them want to read your resume, it should contain some information about your strengths and weaknesses as a potential staff member. If you have gone to the trouble of hiring a resume writer for your resume, it makes sense to allow them to use their expertise to clearly outline both strengths and weaknesses.

Wording is everything

If you are not a native English speaker and this is the reason you hired a resume writer, then you could create several problems for yourself writing your own cover letter. Nouns, verbs, language barriers and misused words can result in a hiring manager dumping your resume into the round file never to be seen again. Even if your resume is written in perfect English, if your cover letter has errors, you could blow any chance of employment.

Summary

In general, if you have hired someone to write your resume for you, you should also be discussing cover letter with them. Cover letters should contain some basic information, but they should provide an all around “hook” to get a hiring manager to review your resume. While a unique cover letter is preferable, you can have one written that allows you to merely change the paragraph where the job itself is discussed. Why risk not getting an interview with a perfectly crafted resume and a sub-standard cover letter?
