If you handle accounting, you must have noted that some documents always crop up in your reports. When accounting, we record financial transactions, analyze them, and make reports.

The importance of accounting to a business cannot be overemphasized more, especially as oversight agencies and tax authorities need these financial statements for various reasons.

Knowing what documents to use is just one part of the bigger picture.  Here we compile a list of the most frequently used documents accounting.

1. Cash Memo

Businesses use cash memos as source documents. It is here that we record all sales and purchase transactions. It is one of the most recurrent accounting documents, which a business gives when it makes cash sales or receive in case of a cash purchase.

The cash memo contains details such as the number of sales, price of goods, applicable discount, and sales tax. Transactions in the cash memo go into the book of accounts and the auditor will always look to cross-reference the cash book and the cash vouchers.

2. Invoice

An invoice is also called a bill. Business must record all their credit sales or credit purchases in this document. For example, when a firm makes sales on credit, it prepares a sales invoice. It details the transaction in terms of the number of goods sold, the price per item, and the total amount sold. The same applies to purchases.

Invoices usually are written in duplicate, with the main (original) copy given to the buyer while the seller keeps the duplicate.

An invoice becomes a bill when the buyer or purchasing entity receives the original invoice copy.

3. Receipt

Businesses use the receipt as proof of payment for goods and services. It is a source document that a seller prepares on account of receiving cash from a second party.

Also prepared in duplicate, the original copy goes to the person giving out cash or paying. The seller keeps the duplicate as a record of the transaction and will show payment details including name, date, the total amount paid, and type of payment (cash/cheque).

4. Pay in Slip

The pay in slip is a proof of transaction document received from a bank for depositing money into a bank account.

The process involves filling up a form at the bank, with details of the depositor, date of transaction and amount deposited.

Pay-in-slip must be signed by the bank clerk with the official bank stamp on the counterfoil. Bookkeepers use the pay in slip counterfoil as a source document for recording the transaction.

5. Cheque

The cheque is one of the most used financial accounting documents. The document is used for financial transactions and is payable once presented to a specified banker. The cheque is an unconditional order in which an entity signed signs directing the banker to pay a certain sum of money. The payee is the person whose details appear on the instrument.

Cheques can be “crossed” which means the cheque is payable to the account of the payee only.

6. Debit Note

We use the debit note as an evidence document. The note is sent to an individual or business against which we have the debit. Businesses draw debit notes against entities from which they anticipate recovering certain amounts of money. For example, if you draw a debit note to a supplier, you expect them to return defective or damaged goods.

Businesses also use a debit note in cases where there is an overpayment. You must indicate all the necessary details in a debit note, including the date and amount debited.

7. Credit Note

Businesses use a credit note to show that they have credited a given party as indicated on the document. The document is written, for example, to a purchaser to show that the business has credited that transaction in their books.

You can prepare a credit note in case you make a payment that turns out to be less than it should have been.

Details are like in debit note. However, easily distinguish between the two by the red ink used to write the credit note.

8. Voucher

A voucher is a business document that records what type of transaction is to be recorded in financial books. Vouchers are prepared using source documents and identify transactions as debit and credit.

There are two types of vouchers:

  • Cash Voucher
  • Non Cash Voucher

Cash vouchers include receipt and cheque payments while non-cash vouchers involve the debit note and credit note.

9. Remittance Advice

We use the Remittance Advice to detail payments sent to a supplier, including whether it’s an invoice or offset credit note.

10. Account statement

This is a document sent out by a supplier to a customer listing the transactions on the customer’s account, including all invoices and credit notes issued and all payments received from the client.

Important tips for handling accounting documents

After knowing the most important accounting documents, a seller has to understand how to use them to get the best results. Some of these documents act as proof of sales, and therefore, they should be perfect when the controlling agencies come asking for them. Additionally, accounting documents can be changed at any time, and so, a seller should know how to update them with the required details. However, as long as one understands the accounting process and knows how to meet local laws’ requirements, everything will be fine. The following tips can make the handling of these documents easier.

Always keep an electronic copy of accounting documents

After preparing cash memos, receipts, and other documents in accounting, a seller should create an electronic copy too. Nowadays, it is easy to manage electronic copies because they do away with the clumsiness associated with hard copies. For instance, they can be retrieved with ease, and they can be stored more safely.

They will help to clear the office of too many documents that may no longer be useful. However, the most significant advantage of electronic copies is that they act as a backup for the rest of the records. If the hard copy gets lost, it can be retrieved and printed. Therefore, these copies will help to solve disputes in the absence of hard copies too.

Be thorough with financial accounting documents

The documents used in accounting require data from various sources, and it is used for specific purposes. For example, cash memos are filed with data regarding the sold items. Because of that, the seller has to ensure that all details are captured in the documents. It becomes even more important when these documents are used as proof of sales.

In that case, the seller will be in a difficult spot if they do not thoroughly check the details. A look at the accounting document list shows that each one needs to capture data for specific purposes, and it is good to keep it in mind when using them.

Use a variety of business documents in accounting

The diversity of accounting documents is an indication that a seller should not rely on one option. If one knows the importance of source documents in accounting, they would know that using them in different forms can bring lots of benefits.

For example, when working with various types of cash memos, it will be easy to identify the one that captures sales data best when there is a variety. When using a receipt as a source document, you may want to know if there is a type that captures more details than the others.

Also, consider consulting a professional accountant when working with accounting documents.

An expert knows how to identify errors and inconsistencies, and they will help fix them to make financial statements accurate. It is more important when doing it for tax compliance purposes.

In addition to that, accountants know what the authorities look for when they ask for financial information, and so, they will help business owners to avoid fines and other penalties.


Accounting documents play a critical role in the handling of business transactions and the preparation of financial statements like the income statement and balance sheet. They are also needed for compliance and tax records. Businesses are now automating many of the accounting processes, and the software a business chooses could be a great addition to keeping financial records.
