The format of letters between companies generally includes four parts:

1. Title: The standard title method for official documents is generally used.

2. Writing: The recipient refers to the recipient of the official letter. It is written on the left side of the first line under the reason, followed by a colon.

3. Text: The content of the official letter is the matter, which is the specific thing the sender wants to tell the other party.

4. Signature: include the name of the unit that issued the letter, the signature of the principal person in charge, and the date.

When writing a letter, you must first pay attention to the conciseness and clarity of the writing and the appropriate use of words. Regardless of whether it is a parallel organization or an unrelated writing, the tone must be calm and courteous, and do not rely on power to overwhelm or force others, nor do you need to be flattering or polite. As for the reply letter, you should pay attention to the pertinence of the writing and the clarity of the reply.

Secondly, letters also have timeliness issues, especially replies should be prompt and timely. Like other official documents, handle correspondence in a timely manner to ensure the normal progress of official business and other activities.
