Types of Accounting Source Documents
There are many different types of source documents. Below is a list of ones used regularly by most businesses.
The buyer may
require a quote from different sellers for the items it wants to buy.
The quotes will be looked at, discussed and a decision made as to which
seller to buy the product from, usually based on who is the cheapest.
After that an order will be placed and the winning supplier will turn
the quote into a sales invoice.
When a business needs to buy an item
it will complete an order form. The order form may be as simple as an A5
sheet from a duplicate book, or it may be a form supplied by the seller
through its on-line website or catalogue. Order forms will not always
show the cost because the buyer may not know the cost when placing an
In many cases the vendor will provide a delivery docket with the items being shipped, posted or delivered. These will often have a description of items being delivered so the buyer can check it against their order immediately upon it's arrival.
Sales and Purchase Invoices
an item is sold the seller will issue a document providing all the
details of the sale. If the seller does not expect cash up front before
sending the item, they will state on their invoice their payment terms
i.e. the length of time the buyer has until it’s time to pay. One
example is for payment to be received no later than 30th of the month
following the date of invoice.
- The seller enters the document into their system as a sales invoice.
- The buyer will enter it into their system as a purchase invoice.
Credit and Debit Notes
the buyer decides not to keep an item but return it to the seller, the
seller will issue a special note to show the amount to be refunded.
- In the supplier’s bookkeeping system this is called a credit note because it reduces the amount owed by the customer.
- In the customer’s bookkeeping system it is called a debit note because it reduces how much they owe to the seller.
a customer pays their bill they will send the supplier a remittance
advice which details the amount and the invoice numbers being paid. It
will be posted either with the check or by itself if payment is made by
Remittances can often be found already printed
as a small cut out section at the bottom of, or down the right hand
side of, the sales/purchase invoice.
A check (cheque) is a special bank note that represents the cash that is being paid by the customer.
check requires the signature of the person who is an authorized signatory of the bank account from which the check is issued. Each check has a
special number on it which should be recorded into the bookkeeping
The name of the payee should be written on the check. If
it is left blank anyone can fill it in with their own name and deposit
the check, thus stealing the money.
Checks should be crossed
across the top with the words ‘not negotiable’, and the printed words
‘or bearer’ crossed off (not all checks have this) so that the check has to be deposited into the payee’s bank account and not cashed, thus
the customer has paid their bill, the supplier can issue a receipt. A
receipt is proof that the payment has been made, which is a good idea
when paying cash. Receipts are usually automatically provided when
buying something from a shop.
a customer pays by cheque or cash, the seller will write a bank deposit
slip which will be taken to the bank and presented together with the
cheques and cash. The deposit slip will show the total amount being
deposited plus a break-down of the cheque amounts and cash.
bank will make a record of the payment so that it shows up on the
payor’s bank statement as a payment received, and on the customer’s bank
statement as a payment made.
Accounting source documents may include loan or lease agreements with
attached payment summaries that show the total amount due plus interest
and administration fees.
