Business invitation letter
Business invitation letter is used to formally invite peers and clients to an event organized by a company. The content of a business invitation letter varies, depending on the event in question. When writing a business invitation letter:
• Begin by adding the sender’s introduction by including the name of the inviting host, his or her position in the company and name of the inviting company below.

• The body of the letter should outline all the pertinent information relating to the event. The most important details include; the purpose of the invitation, venue and date and time of the event. This section also addresses the kind of attire the invited guests should wear.

• In a single sentence, end the letter by appreciating the invited guests. The concluding sentences should include your sign off, salutation remarks and signature.

Informal invitation letter
The informal invitation letter is used when you want to invite guests, friends and family to events like engagement party, wedding invitation and showers. This letter follows more or less the same structure as the business invitation letter. The following guide should be used when writing an informal or personal invitation letter:
• Begin your personal letter of invitation with the name of the host, together with his or her address.

• Use the body of the letter to clarify the reasons for the invitation. The description should be detailed.

• Use a less formal sign-off to close your personal invitation letter. The most common phrases include “Best Wishes”, “Your Sincerely” or simply use “Sincerely”. Conclude your personal invitation letters with a warm salutation.

The formal business invitation letter should be written using paper dimensions and font that fits the standards set by the organization for such invites. The font type and size must be legible. You can also use an appropriate letter of invitation template to write a business invitation letter. The templates are found both online and in word processing applications. Before you submit your business invitation letter or informal invitation letter, always make it a habit to go through the entire letter and make sure there are no grammatical or punctuation errors.
