Dear Ms. Lopez,

My organized nature and attention to detail helped me become a valued member of the Teller’s Manufacturing administrative team. One of my most significant accomplishments was increasing office efficiency by leading the project to go digital, reducing almost all paperwork. I hope to bring my resourcefulness, flexibility and ability to multitask to DHL supplies as an office assistant.

I believe I can play a key role in helping your organization attain its mission of providing excellent customer service and quality products. Your job opening stated that you are looking for an employee to work in a fast-paced environment while maintaining a positive attitude. I believe I am well-suited to this position. Some of my past achievements include:

  • Supporting over 150 office staff with administrative tasks.
  • Answering a high volume of phone calls, directing callers to the correct departments and answering questions.
  • Using advanced Microsoft Office skills, including Word and Excel, to organize company files and data.

I’d like to set up an interview to discuss how my knowledge, skills and abilities can benefit your organization. Please feel free to contact me with a meeting time that works with your schedule.

Dear Mr. Barber,

Streamlining the employee onboarding process to increase completion speed by 70% was my most significant achievement in 2020. I believe that I can offer the same initiative and excellent problem-solving skills as an office assistant at Wood PLC.

My recent accomplishments demonstrate that I have the strategic skills and drive to excel in such a role. These include:

  • Receiving recognition as Employee of the Month in January for independently managing a large project load and meeting 100% of deadlines.
  • Leading a small team to overhaul the office scheduling system, reducing booking errors by 56%.
  • Training five new administrative team members to use Microsoft Office software proficiently.

I hope to further explain how my excellent organizational skills and flexible working style make me the ideal candidate. Please get in touch to schedule an interview.

Office Assistant Cover Letter Checklist

The best office assistant cover letters include five main elements:

1. Heading. This is where you include the essential information, including your name, title, and contact details, the date you wrote the letter, and the addressee’s information. A professional template can ensure the information is clear.

2. Salutation. Find the hiring manager’s name on the job advertisement or company website and use it when greeting them. Mr. or Ms. [Last Name] is the best format. If you can’t find the information, the best practice is to use “Dear Hiring Manager” instead.

3. Introduction. Make a good first impression by introducing yourself. Remember to express your interest in the job.

4. Body paragraphs. Use the main two paragraphs to detail your professional experience, skills, and education. Only include details that are relevant to the position and consider breaking up the paragraphs with a bulleted list.

5. Closing section. Use your closing paragraph to encourage the hiring manager to invite you for an interview. A postscript can be a valuable inclusion as it enables you to highlight one final achievement and leave the hiring manager wanting more.


The opening paragraph is where you need to make a good impression that spurs the hiring manager to continue reading. The best way to do this is to build your introduction around one of the greatest achievements in your resume. Choose something that demonstrates how well-suited you are to the position and that has a quantifiable outcome, rather than a generic fact that can be found in your resume. Don’t forget to affirm your enthusiasm for the office assistant position.


Digitizing client files, which saved consultants two hours each week and decreased errors by 24%, was one of my top accomplishments as an office assistant. I hope to bring that level of initiative and success to KDD Industries.


My name is Jane Doe, and I’m writing to apply for the office assistant position you recently advertised. I have two years of experience providing office support and believe I am well-suited to assist your company.

Body Paragraphs

The bulk of your cover letter is the two body paragraphs. The first paragraph should once again express your interest in the position. Include specific details about why you want the job and why you admire the organization advertising the position.

Use the second paragraph to detail your relevant skills, experience, and achievements. Choose accomplishments that match what the organization needs, can be quantified, and have a positive outcome.


I have two years of experience assisting consultants and executives and find KDD Industries’ reputation for great customer service appealing. My focus on finding new ways to increase efficiency in the office is the ideal fit for KDD Industries’ emphasis on using innovation to produce superior products.


My past projects have given me the skills necessary to help KDD Industries continue to succeed. My past achievements include:

  • Implementing new scheduling software that created efficiencies for consultants and was preferred by 77% of clients
  • Organizing travel and accommodation for executives to more than 50 conferences and destinations each year
  • Designing new client welcome packages that helped increase conversion rates by 32%


You mention in your advertisement that you require someone with experience providing general office support and assistance to management. I have two years of experience in this field and would be the perfect fit for your company.


Currently, I am responsible for:

  • Arranging travel for executive-level staff
  • All filing and scheduling for consultants and executives
  • Answering initial customer inquiries


The closing section is your last chance to make a good impression. Make sure you include a call to action that encourages the hiring manager to schedule an interview, rather than just thanking them for their time and attention.

You can gain extra points by including a postscript. This should include one final achievement that draws the hiring manager’s eye and leaves them wanting more information. The postscript doesn’t necessarily have to be about work experience; if you’ve won an award or done volunteer work, you can include it here. Just make sure it’s relevant to the position.


I’d like to arrange an interview to discuss how my experience and skills can bring additional efficiencies and success to KDD Industries. Don’t hesitate to contact me with a time that suits you.


Best regards,

Jane Doe, LSW


P.S. I’d love to tell you about my volunteer work organizing the offices of a local wildlife rescue organization!
