Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. “Characteristics of a good business letter” is set every year; “parts of a business letter with example” was a 10-mark question in January 2025, and the January 2026 paper asked for the features plus “an imaginary business letter of your choice”. Always draw a letter: marks go to the layout as much as to the list.

1. Meaning and functions

A business letter is a written communication between two business parties, or between a business and its customers, government or others, on a business matter. It is used to make enquiries, send quotations, place and confirm orders, make and settle complaints, collect dues, and announce changes. It serves as a record and as evidence: an offer and its acceptance by letter form a contract. It also builds goodwill, since for many customers the letter is the only contact they have with the firm.

2. Parts of a business letter

  1. Letterhead (heading): name, address, telephone, e-mail, website, GSTIN or CIN of the firm, printed at the top.
  2. Reference number: “Ref: SF/PUR/214/2026”, for filing and quoting in reply (“Your ref.” and “Our ref.”).
  3. Date: written in full, “5 January 2026”; avoid 5/1/26, which is read differently in different countries.
  4. Inside address: name, designation and address of the receiver.
  5. Attention line (optional): “Kind attention: The Purchase Manager”.
  6. Salutation: “Dear Sir/Madam”, “Dear Mr. Rao”.
  7. Subject line: “Sub: Supply of 50 study tables”, telling the reader at once what the letter is about.
  8. Body: (a) opening paragraph that refers to earlier correspondence or states the purpose; (b) main paragraph(s) with details; (c) closing paragraph stating the action expected.
  9. Complimentary close: “Yours faithfully” (with “Dear Sir”) or “Yours sincerely” (with a named salutation).
  10. Signature block: for the firm name, signature, name and designation of the signatory.
  11. Enclosures: “Encl: (1) Price list (2) Catalogue”.
  12. Copy to (c.c.) and postscript (P.S.) where needed; a P.S. is for an afterthought and should be rare in business letters.

4. Characteristics of a good business letter

Inner qualities (content and language)

  1. Clarity: simple words, one idea per sentence, no ambiguity.
  2. Conciseness: no padding or outdated phrases (“we beg to state”, “your esteemed favour”).
  3. Completeness: all facts, figures and dates needed for action.
  4. Correctness: accurate facts and figures, grammar and spelling.
  5. Courtesy: polite, prompt and tactful, even when refusing or complaining.
  6. Consideration (you-attitude): written from the reader’s point of view.
  7. Concreteness: specific facts in place of general claims.
  8. Coherence: logical order; each paragraph follows from the last.
  9. Persuasiveness: it should move the reader to the desired action.
  10. Sincerity: no exaggeration or false promises.

Outer qualities (appearance): good quality paper and printed letterhead; neat typing with proper margins and spacing; standard layout; correct folding and envelope; no corrections or over-writing. The appearance makes the first impression.

5. Model letter (imaginary details): letter of enquiry

Dear Sir,

Sub: Enquiry for supply of study tables

We are opening a new block of our college in June 2026 and need about 50 study tables of teak or sheesham wood, roughly 120 cm × 60 cm, with one drawer each.

Please send us your lowest quotation, with your catalogue, stating the price per table, discount for bulk orders, GST, delivery period, terms of payment and the warranty you offer.

We would appreciate your reply by 15 January 2026, as we intend to place the order this month.

Yours faithfully,

Trap. When the question says “imaginary details”, invent all of them (names, addresses, dates, figures) but keep them consistent and plausible. Leaving blanks or writing “XYZ” throughout loses marks under completeness and concreteness.

How this is examined

“Write down the salient features of a good business letter. Write an imaginary business letter of your choice” (January 2026, 100 marks, 16); “characteristics of a good business letter” (6 marks January 2026 and 2025, 10 marks August 2024); “What is a business letter? Explain the parts with example” (January 2025, 10). The order, quotation, complaint and response letters are in the next note.
