This letter can have legal ramifications for your purchaser.
In some cases, a purchaser may request a letter of confirmation of receipt of an order. This is usually because they have an obligation to prove compliance with terms of contracts or agreements with their own clients or other parties.
Generally speaking this letter of confirmation will be requested in writing when the order is received.
It's important to your client that you provide confirmation in the manner requested, specifying any information required.
In the example below, the writer, a wholesaler, has been asked by a retailer to confirm the price and particulars of an order for white goods, in addition to confirming receipt. As you can see, the order relates to a large financial outlay by the client.
The client may have required acknowledgment of the order for finance or insurance purposes, which is why providing confirmation can be so important:
