Debit Note 

A debit note is usually sent by a seller to a buyer to indicate an increase in the amount he (the buyer) owes. That is, the buyer’s account has been debited with a certain amount as shown in the books of the seller. It is a document similar to an invoice. This is because it shows the amount owed by the owner to the supplier of goods and which must be paid. A debit note may be sent to a customer (buyer).

In making purchases in an organization, the buyer has to prepare some documents. The following are some of them:



A requisition is a document meant for internal use only. It must contain all the things needed by the department and the type of materials, the quantity, quality and size required. It must be signed by the head of that department and sent to the purchasing officer.

He/she then sends a letter or makes a telephone call to enquire about availability, prices and possible delivery date. Such a letter of enquiry usually contains the information taken from the requisition, such asSize, quantity and quality, delivery date, terms of payment and so on. The supplier will reply the letter of enquiry by sending a catalogue and price list or price quotation.



An order is a document used by the buyer to the seller that a specific goods should be made available by the seller to the buyer at a specified time, date and price. When the customer receives a catalogue and price list, he can then order goods by mail, by telephone or through the Internet, especially if such goods are needed very urgently.
