Section 1 Introduction to Business Correspondence
Purpose and Importance
Business correspondence is formal written communication used in professional contexts. Unlike casual communication, business letters establish credibility, create formal records, and convey professional respect (Bovée & Thill, 2005). A well-written business letter can open doors for employment, resolve conflicts, and strengthen professional relationships.
Why Business Correspondence Matters
Employers judge candidates partly through their written communication. A poorly written application letter can eliminate you from consideration, while an excellently written letter can set you apart from other candidates (Besson, 2015). Business correspondence demonstrates your attention to detail, professional standards, and communication skills.
Section 2 Business Letter Format and Structure
Standard Business Letter Format
Professional business letters follow a standard format that includes sender information, date, recipient address, salutation, body paragraphs, closing, and signature (Munter & Hamilton, 2014). This format ensures clarity and maintains professional appearance.
• Letterhead or sender's address
• Date
• Recipient's address
• Salutation (Dear Mr./Ms. Last Name)
• Body paragraphs
• Professional closing (Sincerely, Yours truly)
• Signature with typed name
Spacing and Margins
Standard business letters use 1-inch margins on all sides and single spacing within paragraphs with double spacing between paragraphs (St. Onge, 2018). This spacing provides professional appearance and readability.
Section 3 Letters of Application
Purpose and Strategy
Application letters introduce candidates to potential employers and explain why the candidate is ideal for the position (Bovée & Thill, 2005). An effective application letter demonstrates specific knowledge of the company and matches the applicant's qualifications to job requirements.
Key Elements of Effective Application Letters
Strong application letters open with attention-grabbing statements, clearly explain how your qualifications match position requirements, and include specific achievements rather than generic claims (Purdy & Saffire, 2014). They should be concise (one page), error-free, and demonstrate genuine interest in the position.
Example: Letter of Application for Rector Position
Department of Engineering
Federal Polytechnic, Lagos
Lagos, Nigeria
24th May, 2026
The Governing Council,
Federal Polytechnic, Nassarawa,
Karu, Nassarawa State,
Nigeria.
Dear Sir/Madam,
APPLICATION FOR THE POSITION OF RECTOR, FEDERAL POLYTECHNIC, NASSARAWA
I am writing to formally express my strong interest in the position of Rector at Federal Polytechnic, Nassarawa, as advertised in the Nigerian Tribune on 15th May, 2026. With over fifteen years of experience in higher education management, coupled with a proven track record of academic excellence and institutional development, I am confident that my expertise and vision align perfectly with the polytechnic's strategic objectives and aspirations for growth and improved service delivery to students and stakeholders.
I hold a Doctor of Philosophy degree in Engineering Management from the University of Lagos, complemented by extensive professional qualifications in educational administration and institutional governance.

In my current role as Deputy Director of Academic Affairs at Federal Polytechnic, Lagos, I have successfully overseen the implementation of comprehensive curriculum reforms, the establishment of new academic programmes, and the improvement of academic standards across multiple departments, resulting in a fifteen percent increase in student enrolment and enhanced institutional reputation within the nation's tertiary education sector.
My administrative experience extends to strategic planning and financial management, where I have demonstrated proficiency in budget development, resource allocation, and fiscal accountability. I have spearheaded initiatives to strengthen partnerships with international institutions, leading to the establishment of student exchange programmes and collaborative research projects that have positioned the institution among the leading polytechnics in West Africa. Additionally, I have championed efforts to improve staff welfare and motivation, resulting in significant improvements in staff retention and institutional morale.
Beyond my institutional responsibilities, I am deeply committed to advancing the quality of technical and vocational education in Nigeria. I believe that polytechnics play a crucial role in providing industry-relevant skills training and contributing to national economic development. Under my prospective leadership at Federal Polytechnic, Nassarawa, I would focus on strengthening linkages with industries, enhancing curriculum relevance to market demands, improving infrastructure and learning facilities, and fostering a culture of innovation and excellence among both staff and students. I am confident that my vision and commitment will help position the polytechnic as a beacon of quality education and professional development in the region.
I am prepared to bring my expertise, energy, and dedication to the position of Rector and would welcome the opportunity to discuss how my background, accomplishments, and vision can contribute to the continued success and advancement of Federal Polytechnic, Nassarawa.

Section 4 Letters of Inquiry and Request
Purpose
Inquiry letters ask for specific information or clarification (Ober, 2008). Request letters ask recipients to take specific action. Both require clear, concise writing that makes the request easy to understand and answer.
Effective Inquiry Letters
Clear inquiry letters state the specific information needed, explain why you need it, and provide a deadline if appropriate (St. Onge, 2018). They should be polite but direct, respecting the recipient's time.
Example: Letter of Inquiry for Professional Training Programmes
Chukwu Consulting Limited
Plot 45, Lekki Phase 1
Lagos, Nigeria
24th May, 2026
The Principal, Human Resources Department,
Federal Polytechnic, Nassarawa,
Karu, Nassarawa State,
Nigeria.
Dear Sir/Madam,
INQUIRY REGARDING PROFESSIONAL TRAINING AND CAPACITY BUILDING PROGRAMMES
I am writing to inquire about the professional training and capacity building programmes offered by Federal Polytechnic, Nassarawa. My organisation, Chukwu Consulting Limited, is currently developing a comprehensive staff development initiative for our employees across various departments, and we are seeking a reputable institution to facilitate customised training programmes tailored to our specific organisational needs and industry requirements.
We are particularly interested in programmes covering the following areas: project management and strategic planning, information technology and digital transformation, financial management and cost control, customer service excellence and organisational communication, leadership development for mid-level managers, and occupational health and safety compliance. We anticipate requiring training for approximately one hundred employees over the next twelve months, with training sessions to be conducted both at your institution and at our office premises in Lagos through a hybrid delivery model.
To enable us to assess the suitability of your programmes for our organisation's requirements, I would appreciate responses to the following specific questions. First, what is the range of professional training programmes currently available at the polytechnic, and do you offer customised programmes tailored to specific organisational needs and industry sectors? Second, what are the qualifications and experience levels of the resource persons and trainers who would facilitate these programmes, and what mechanisms ensure training quality and professional standards? Third, what are the total costs for a typical three-day professional training programme for a group of forty to fifty participants, and are discounts available for larger cohorts or longer duration engagements? Fourth, what are the accommodation and catering facilities available for participants, and what are the associated costs? Finally, what is the typical timeline for programme development and commencement once we have finalised the training requirements and learning objectives?
We would also appreciate receiving your current training brochure or catalogue detailing all available programmes, including course outlines, duration, costs, and scheduling information. Additionally, we would find it helpful to receive contact information for references from other organisations that have utilised the polytechnic's professional training services, so that we can verify the quality and effectiveness of the programmes.
If possible, we would like to arrange a meeting with the appropriate personnel from your training and professional development department to discuss our requirements in detail and explore how the polytechnic can best serve our organisation's capacity building objectives. We are flexible with scheduling and can accommodate your preferred meeting times at either your institution or our office location in Lagos.
Thank you for your attention to this inquiry. I look forward to receiving the requested information at your earliest convenience so that we can proceed with the planning and implementation of our training programmes.
Yours faithfully,
Mr. Emeka Chukwu
Development Officer

Section 5 Letters of Invitation and Response
Formal Invitation Letters
Formal invitations provide essential details: event date, time, location, dress code, and RSVP deadline (Munter & Hamilton, 2014). They should be courteous and clear about what is expected of attendees.
Responding to Invitations
Professional responses to invitations should be prompt, gracious, and clearly confirm or decline attendance (Bovée & Thill, 2005). A simple thank-you note following the event strengthens professional relationships.
Section 6 Complaint Letters and Resolutions
Writing Effective Complaints
Complaint letters must be factual, specific, and professional despite frustration (St. Onge, 2018). They should document the problem clearly, explain the impact, and specify what resolution you seek. An angry tone undermines your position; professionalism is more persuasive.
Example: Letter of Complaint Regarding Delayed Certificate Issuance
78 Abacha Road
Kano, Nigeria
24th May, 2026
The Rector,
Federal Polytechnic, Nassarawa,
Karu, Nassarawa State,
Nigeria.
Dear Sir,
A COMPLAINT REGARDING DELAYED ISSUANCE OF GRADUATION CERTIFICATES
RE: FPN/ND/BUS/2016/089
I am writing to lodge a formal complaint regarding the persistent delays in the issuance of my graduation certificate and the lack of responsiveness and professionalism displayed by the Records and Examinations Office of Federal Polytechnic, Nassarawa. My student registration number is FPN/ND/BUS/2016/089. I completed all academic requirements for my programme in June 2019 and participated in the graduation ceremony in August 2019. However, it is now May 2026—nearly seven years later—and I have still not received my official graduation certificate, despite making numerous requests and enquiries to the institution.
The delay in certificate issuance has caused me considerable personal hardship and professional difficulty. I have been unable to pursue advanced educational opportunities, including applications for postgraduate programmes at universities both nationally and internationally, because these institutions consistently require verified copies of my diploma certificate. Additionally, many employers I have approached for employment have expressed reluctance to proceed with hiring without official documentary evidence of my qualifications. This has directly impacted my career advancement and income-earning potential, placing me at a significant disadvantage compared to my peers who graduated at the same time and have since obtained their certificates.
I have made repeated efforts to resolve this matter through the appropriate channels. I submitted written requests to the Records and Examinations Office on 12th November, 2021, and again on 28th March, 2023, requesting the issuance of my diploma certificate. In response to these requests, I received only vague assurances that the certificate would be "processed soon" without any specific timeline or concrete action. When I visited the office in person on 15th February, 2024, and again on 10th September, 2025, I was met with unhelpful attitudes from staff members who appeared unwilling or unable to assist me. On one occasion, I was told that my file could not be located despite providing my complete student registration number and other identifying information.
Such unresponsiveness and lack of professionalism is entirely unacceptable and falls far short of the standards expected from a federal institution responsible for serving thousands of graduates and stakeholders. This situation reflects poorly on the institutional reputation and suggests systematic failures in the administration of the records office. As an alumna of Federal Polytechnic, Nassarawa, I feel betrayed by the institution's failure to provide this basic and fundamental service that I have legitimately earned through the successful completion of my academic programme.
I hereby demand that the institution take immediate corrective action to resolve this matter. Specifically, I require that my graduation certificate be issued within fourteen days of the receipt of this letter. If the original document cannot be located, I request that a certified duplicate certificate be issued immediately with a covering letter confirming the completion of my academic requirements and the legitimacy of my qualification. I also expect a written apology from the Records and Examinations Office acknowledging the institutional failure and the inconvenience and hardship caused to me by this inexcusable delay.
Should the institution fail to take satisfactory action within the specified timeframe, I will be forced to escalate this matter through formal channels, including lodging complaints with the National Board for Technical Education and pursuing legal remedies to protect my rights and seek appropriate compensation for the damages and losses I have suffered as a result of this institutional failure. I am also prepared to contact relevant media outlets and professional bodies to publicise this matter if it is not resolved expeditiously.
I trust that you will treat this matter with the urgency and seriousness it deserves and that the institution will take immediate corrective steps to prevent similar occurrences affecting other graduates. I await your prompt response and concrete action.
Yours faithfully,
Mrs. Amara Okoro

Section 7 Recommendation and Reference Letters
Writing Strong Recommendations
Recommendation letters must be honest, specific, and evidence-based (Ober, 2008). They should provide concrete examples of the person's competence and character rather than general praise. A weak recommendation is worse than none at all.
Requesting Recommendations
When requesting a recommendation, provide the recommender with sufficient context: the position description, relevant accomplishments, and deadline (Purdy & Saffire, 2014). Give adequate notice—never ask for recommendations at the last minute.
Section 8 Professional Register and Language
Maintaining Professional Tone
Business correspondence requires formal register with precise vocabulary and standard grammar (Munter & Hamilton, 2014). Avoid contractions, slang, and overly casual language. Maintain consistency in formality throughout the letter.
Word Choice in Business Letters
Choose words carefully: "I look forward to" is more professional than "I'm excited about." "Please provide" is more direct than "Could you possibly provide." Clear, simple language is more professional than unnecessarily complex vocabulary (St. Onge, 2018).
Section 9 Replies and Follow-up Correspondence
Professional Replies
Reply letters should acknowledge the original communication, respond to all points raised, and conclude with clear next steps (Bovée & Thill, 2005). Timely replies demonstrate professionalism and respect for others' time.
Follow-up Letters
Follow-up letters after meetings or interviews should be prompt, brief, and reinforce key points discussed (Ober, 2008). They provide opportunity to add information omitted in the original conversation and reiterate interest or commitment.
Section 10 Digital Communication and Email Etiquette
Email as Business Correspondence
Professional emails should follow business letter conventions even though they are digital (St. Onge, 2018). Subject lines should be specific and professional. Greeting and closing should be appropriate to the relationship and context.
• Write meaningful subject lines
• Use professional greetings and closings
• Keep messages concise and organized
• Proofread before sending
• Respect "Reply All" boundaries
• Include signature with contact information
• Respond within 24 hours when possible
Tone in Digital Communication
Email tone is often misinterpreted because non-verbal cues are absent (Munter & Hamilton, 2014). What seems direct might be perceived as harsh; what seems casual might seem unprofessional. Reread emails to ensure tone is appropriate before sending.
