(purchase order) will usually come first, as it is the expressed intent of a buyer to purchase goods and services from the seller. If a verbal agreement is made over the phone, for example, in the case of a tight timeline, a seller may send the product and invoice first, with the buyer later sending a P.O. Number because the buyer sends the purchase order, as it is an agreement made by them to pay later for an order they are placing now. It is up to the purchasing party to create the correct paperwork and send it to the seller with all important details and essential information included. Buyers will create a purchase order listing the types of items as well as the quantities they would like to buy. These documents not only help clients buy supplies, but they also provide a detailed paper trail, keep buyers and sellers on the same page, and serve as proof in the case of a dispute.

Typos can easily occur, and spelling errors in the company name or other more trivial information on the invoice doesn’t necessarily require correcting.

If the customer has already paid, make a correction adjustment on a future invoice, or issue another invoice or credit correcting the mistake.
