Invoice vs Statement

What is an invoice?

An invoice is a document issued by a business requesting payment for goods or services that have been supplied. Each invoice relates to a specific transaction and normally includes customer information, invoice items, payment terms, taxes where applicable, and the total amount due.

Invoices are commonly used by freelancers, contractors, sole traders, and businesses to keep accurate financial records while requesting payment from customers.

What is an account statement?

An account statement is a document that summarises activity between a business and a customer over a chosen period. Rather than focusing on one transaction, it shows several invoices, payments received, credits, refunds, and any remaining balance.

Businesses often send statements monthly so customers can quickly review everything outstanding on their account.

Invoice vs statement

Although invoices and statements may contain similar customer information, they have different purposes.

An invoice requests payment for one specific sale. A statement provides an overview of multiple transactions that have already taken place.

• An invoice requests payment for one transaction
• A statement summarises account activity
• Invoices include line items and payment terms
• Statements list invoices, payments, credits, and balances
• Invoices are normally sent after goods or services are supplied
• Statements are often sent at regular intervals such as monthly

When should businesses send invoices?

Businesses normally issue an invoice once goods have been delivered or services have been completed, unless they require payment in advance or request a deposit.

Sending invoices promptly helps customers process payment sooner while improving business cash flow.

When should businesses send statements?

Statements are commonly sent at the end of a week, month, or another accounting period. They are particularly useful when a customer has multiple unpaid invoices or makes regular purchases.

Rather than replacing invoices, statements simply provide a convenient summary of the customer's account.

What information should an account statement include?

A professional account statement should provide enough information for the customer to understand the status of their account.

• business details
• customer details
• statement date
• statement period
• invoice numbers
• invoice dates
• payments received
• credit notes
• remaining balance

Why businesses use account statements

Statements make it easier for customers to review outstanding balances without searching through individual invoices. They also help businesses reduce confusion when customers have several unpaid invoices.

Many finance departments use statements during payment runs because they provide a complete picture of what remains outstanding.

• summarise outstanding balances
• reduce customer confusion
• improve payment tracking
• support bookkeeping
• highlight overdue invoices

Can a statement replace an invoice?

No. A statement should not replace an invoice. Customers still require individual invoices that clearly describe the goods or services supplied together with payment terms and the total amount due.

The statement simply summarises activity and references those invoices.

How invoices and statements work together

Invoices and statements are often used together throughout the payment process. After each sale, the supplier issues an invoice requesting payment. Later, an account statement may summarise all unpaid invoices together with any payments already received.

This allows customers to quickly identify which invoices still require payment while helping businesses maintain organised financial records.

Keeping invoice and statement records organised

Businesses should keep statements together with the invoices they reference. Organising documents using invoice numbers, customer names, or accounting periods makes it easier to locate records when answering customer queries or preparing financial reports.

Consistent document organisation also helps businesses monitor outstanding balances and reconcile payments more efficiently.

Create professional invoices

Before businesses can produce accurate account statements, they first need clear and professional invoices. Each invoice should include unique invoice numbers, customer details, payment terms, invoice items, taxes where applicable, and the final amount due.
