Invoice vs Statement: What's the Difference?
An invoice says "pay for this." A statement says "here's everything on your account." Businesses with regular customers use both.
An invoice requests payment for a specific sale. A statement (or statement of account) summarizes all invoices, payments and credits for a customer over a period, usually a month, and shows the balance outstanding.
| Invoice | Statement | |
|---|---|---|
| Covers | One sale or billing period | All activity over a period |
| Purpose | Request payment | Summarize the account and balance |
| Sent | When goods/services are supplied | Periodically (often monthly) |
| Shows | Items, prices, tax, total, due date | Opening balance, invoices, payments, credits, closing balance |
| Used for tax? | Yes (the invoice is the tax document) | No |
| Paid from? | Yes | Sometimes, by customers on account |
When statements are useful
- Customers on account who buy frequently (trade suppliers, wholesalers, builders' merchants)
- Several open invoices for the same customer
- Reconciling your records with the customer's before year end
- Chasing overdue amounts without sending every invoice again
- Showing credits and payments that have been applied
If you're a freelancer with one invoice per client per month, you probably don't need statements.
What a statement shows
- Your details and the customer's details
- Statement date and the period covered
- Opening balance
- Each invoice (number, date, amount)
- Each payment and credit note
- Closing balance
- Ideally, an aging summary: current, 30, 60, 90+ days
Example
Statement of account: Greenline Builders Ltd, 1–31 August 2026
Date Reference Charges Payments Balance 1 Aug Opening balance £1,240.00 4 Aug INV-0301 £860.00 £2,100.00 9 Aug Payment, thank you £1,240.00 £860.00 18 Aug INV-0309 £2,310.00 £3,170.00 22 Aug CN-0012 (return) £140.00 £3,030.00 31 Aug Closing balance £3,030.00 Current: £2,170.00. 30 days: £860.00.
Statements don't replace invoices
A statement is a summary. The invoice is still the document that supports the sale for tax purposes, and business customers need the invoices themselves to pay and to reclaim VAT. Send the invoice for each sale, then a statement periodically if it helps.
Statements as a collection tool
A statement is a neutral, non-confrontational way to remind a customer about overdue invoices. The aging section shows at a glance what's late. Many businesses send statements on the first working day of each month, followed by direct reminders for anything over 30 days. See accounts receivable aging.

Open the invoice generatorBank statements, briefly
"Statement" also means a bank or card statement, which lists transactions on your account. That's different: it's a record from your bank, not a document you issue. Bank statements are useful as proof of payment, but they aren't a substitute for invoices and receipts in your business records.
How often to send statements
Monthly is the norm, usually on the first working day of the month, covering the previous month. Businesses with only a few customers on account sometimes send them quarterly. Whatever you choose, be consistent: customers learn to expect them and some will pay from the statement rather than from individual invoices.
Two styles of statement
Balance forward: starts with the previous balance, lists the period's invoices and payments, and ends with the new balance (like the example above). Easy to read, and common for small businesses.
Open item: lists only the invoices that are still unpaid, each with its own age. Better for customers who pay invoice by invoice, because they can see exactly which ones remain.
If you use accounting software, it will usually offer both. If you're doing it by hand, open item is simpler to keep accurate: it's just a filtered list from your invoice log.
Frequently asked
Do statements need a number? Not usually. Date them and state the period covered.
Can a customer pay from a statement? Yes, many do. Make sure the statement shows your payment details and asks them to reference the invoice numbers they're paying.
Should a statement include interest on late invoices? If you charge interest, show it as a separate invoice listed on the statement, so there's a proper document behind it.
Is a statement enough for a VAT claim? No. The customer needs the VAT invoices themselves.
