Request for Invoice Letter Sample

Sales Invoice Letter

A sales invoice letter is a letter that a business or salesman gives toward a client or customer together with, prior to, or after, the issuance of the sales invoice.

For sake of brevity, there are two main types of sales invoice letters and those are

• invoice cover letter and
• invoice reminder letter.

Invoice Cover Letter

Businesses usually include an invoice cover letter in their sales invoice when the business transaction involved is rife with complexities. For sake of clarity, a sales invoice is a document that contains an enumeration of the products or services that the customer availed. It is also accompanied by payment details such as credit or debit options, amount added from tax, and of course, the price of the services or goods. That is why a cover letter is only necessary in specific circumstances, and most of the time, the purposes for including such cover letter are

• when there are specific details in the business transaction that cannot be contained in a small and standardized format of a sales invoice and
• when the business owner or sales person wants to solidify the bond between him and a certain client by adding a personal touch to their business relationship through a formal request cover letter.

Invoice Letter to Vendor

Invoice Reminder Letter

An invoice reminder letter or an overdue bill reminder letter is a simple letter that denotes the outstanding bill of a particular customer. This is usually sent when a customer has failed to make his or her payment on or before the time the bill is overdue. Logically, the invoice reminder letter is sent days or weeks after the first sales invoice has been sent to the customer.

This letter usually follows the following format:

• A formal opening.
• A clear statement of the letter’s intent, which is to notify the customer of his or her overdue balance.
• A specific enumeration of the product/s or service/s that the notice pertains to and their corresponding prices. In this part, you may also include the date and specific time that the customer purchased the product or availed the service. This encourages transparency in your dealings and your customer cannot deny your claim.
• A respectful sample statement that states how much you understand that such occurrence must have been a mere oversight on the part of your customer and that it is perfectly normal to forget sometimes.
• A repetition of your request for your customer to make good with his end of the business transaction.
• A respectful closing.
