Quick summary

Let’s unwrap more differences to let you clearly understand the meaning and purpose of each document.
📌 Key takeaways

- An invoice statement provides the complete overview of invoices, payments, and outstanding balances for the specific billing period.
- Both statements and invoices are necessary for improving cash flow management.

- A clear understanding of invoice vs statement helps you reduce confusion about payments.
What is a statement?

A statement, also known as a statement of account, is a financial statement that summarizes all the transactions. It includes invoices, outstanding balances, payments received, any pending dues, and other account activities.
Therefore, a customer gets a clear idea of the account status and the unpaid amounts. Compared to an invoice, a billing statement is broader and includes details of multiple transactions.
Businesses usually send statements to their customers weekly, monthly, or yearly. This helps them get the account summary and payment reminder. Hence, the primary objective of the statement is to inform the customer about the transaction history and the due balance.
A typical statement includes the following information:
- Customer information
- Invoice number and date
- Statement period
- Payment received
- Outstanding balances
- Credit notes or other adjustments
- Total amount due
What is an invoice?

An invoice is a document that the seller sends to the buyer to request payment for products sold or services provided. It outlines line-item details, such as product or service descriptions, quantities, and unit prices.
Therefore, the purpose of an invoice is to request payment of the outstanding amount. An invoice is also useful for tracking payments and maintaining accurate financial records.
Unlike a statement, which summarizes multiple transactions over the period, an invoice includes only one transaction.
A typical invoice includes the following information:
- Invoice number
- Date of issue
- Due date
- Currency
- Customer name and contact information
- Business details or seller details
- PO number
- Line item description with unit price and quantity
- Taxes and discounts (if applicable)
- Total due amount
- Payment terms
- Additional notes
- Signature of issuer

Statement vs invoice: Key comparison
The major difference between a statement and an invoice is their purpose. A statement is a document that summarizes overall transactions, whereas an invoice is a document requesting payment.
The following table reflects the true information on the statement vs. the invoice:
| Aspect | Statement | Invoice |
|---|---|---|
| Usage | A statement is a document that summarizes the complete accounting activity. | An invoice is a document issued by the seller that requests payment from the buyer. |
| When sent | The billing statement is sent periodically, weekly, monthly, or annually. | The invoice is sent immediately after a sale. |
| Includes | It includes account summary, previous balance, due amount, and credits. | It includes an itemized list of products/services, quantities, prices, taxes, and the total due. |
| Payment request | It’s not directly related to the payment request but includes outstanding payments. | It is strongly related to the payment request for the sale and includes the due payment. |
| Transaction details | It includes multiple transactions during the period. | It mainly focuses on a single transaction. |
| Who issues | Business owners, banks, vendors, and other service providers. | Business owners, sellers, contractors, and other freelancing professionals who sell products or services. |
Here is a real-life example demonstrating the invoice and statement difference.
Suppose a furniture manufacturer sells a piece of furniture to a regular customer. In the first sale, the customer purchased 4 sets of chairs; in the second sale, 2 beds. The manufacturer may issue separate invoices for both sales in the following way:
| Invoice No. | Product | Quantity | Unit price | Total cost |
|---|---|---|---|---|
| INV -101 | Chair | 4 | $100 | $400 |
| INV -102 | Bed | 2 | $500 | $1000 |
| Total Due Amount | $1400 | |||
Now, when the manufacturer issues the statement, it will look as follows:
| Date | Description | Amount | Status |
|---|---|---|---|
| 1 May | Invoice INV – 101 | $400 | Unpaid |
| 10 May | Invoice INV – 102 | $1000 | Unpaid |
| 15 May | Payment received | $1000 | Paid |
| 30 May | Outstanding balance | -$400 | Due |
The total amount due per the invoice was $1,400. When the customer pays $1000, the outstanding balance is $400, as mentioned in the statement.
