Business letter


A business letter is a letter from one company to another, or between such organizations and their customers, clients, or other external parties. The overall style of letter depends on the relationship between the parties concerned. Business letters can have many types of content, for example to request direct information or action from another party, to order supplies from a supplier, to point out a mistake by the letter's recipient, to reply directly to a request, to apologize for a wrong, or to convey goodwill. A business letter is sometimes useful because it produces a permanent written record, and may be taken more seriously by the recipient than other forms of communication.

General format

Margins

Side, top and bottom margins should be 1 to 1 1/4 inches. One-page letters and memos should be vertically centered.

Font formatting

No special character or font formatting is used, except for the subject line, which is usually underlined.

Punctuation

The salutation or greeting is generally followed by a comma in British style, whereas in the United States a colon is used. The valediction or closing is followed by a comma.

Form

The following is the general format, excluding indentation used in various formats:

 Attention 
Dear 
Enclosures

Indentation formats

Business letters conform to generally one of six indentation formats: standard, open, block, semi-block, modified block, and modified semi-block. Put simply, "semi-" means that the first lines of paragraphs are indented; "modified" means that the sender's address, date, and closing are significantly indented.

Standard

The standard-format letter uses a colon after the salutation and a comma after the complimentary closing.

Open

The open-format letter does not use punctuation after the salutation and no punctuation after the complimentary closing.

Block

In a block-format letter, all text is left aligned and paragraphs are not indented.

Modified block

In a modified-block format letter, all text is left aligned, paragraphs are not indented, and the author's address, date, and closing begin at the center point.

company name and address
date
TO

Semi-block

Semi-block format is similar to the Modified block format, except that the first line of each paragraph is indented.

Modified semi-block

In a modified semi-block format letter, all text is left aligned, paragraphs are indented, and the author's address, date, and closing are usually indented in same position.
