What is a statement of account?
A statement of account (also called a customer statement or account statement) is a summary you send to a customer showing their activity with you over a period, usually a month. It lists invoices issued, payments received, credits applied and the balance still owed. Unlike an invoice, which bills for one sale, a statement pulls everything together so the customer can see their whole account at a glance.
When do you need one?
- Customers on credit terms who receive several invoices a month and pay on account.
- Month-end reminders. A statement is a polite, factual nudge that lists everything outstanding. For wording ideas, see how to ask for payment.
- Reconciliation. Customers' accounts teams compare statements against their own records to catch missing invoices or unapplied payments.
- Collections. When an account is overdue, an aged statement shows exactly how old each balance is.
- Audit and year-end. Auditors and finance teams often request a statement to confirm balances.
Open-item vs balance-forward statements
There are two common styles. An open-item statement lists only the invoices that are still unpaid, each with its open amount, and totals them into the balance due. A balance-forward statement starts with the opening balance from the last statement, adds new invoices, subtracts payments and credits received in the period, and ends with a closing balance. Open-item statements are simpler for customers who pay invoice by invoice; balance-forward statements suit accounts with frequent small transactions. The sample on this page uses the open-item style.
What to include on a statement of account
- Statement number and statement date
- Your business name, contact details and logo
- Customer name, account number and billing address
- The statement period, e.g. "September 1 – October 31, 2026"
- Opening balance carried forward (if any)
- Each invoice: number, date, due date and amount
- Payments and credit notes received during the period
- Closing balance due
- Aging summary: current, 1–30, 31–60, 61–90 and 90+ days
- Payment instructions and a request to pay or reconcile
Worked example
Brightline Print Co. has three open invoices with a customer at the end of October. Its statement SOA-2026-10, dated November 1, lists each invoice as a line:
| Invoice | Date | Due | Age | Open amount |
|---|---|---|---|---|
| INV-1041 | Sep 3, 2026 | Oct 3 | 31–60 days | $1,250.00 |
| INV-1048 | Sep 24, 2026 | Oct 24 | 1–30 days | $780.00 |
| INV-1055 | Oct 9, 2026 | Nov 8 | Current | $2,140.00 |
| Balance due | $4,170.00 | |||
The aging tells the customer that $1,250 is more than 30 days overdue, $780 is recently overdue and $2,140 is not yet due. The notes ask for payment within 15 days and invite the customer to flag any differences.
Tips and common mistakes
- Match your invoice numbers exactly. The customer will look up each one; a typo causes delays.
- Apply payments before you send. Nothing annoys a customer more than a statement showing an invoice they already paid.
- Show partial payments. If an invoice is partly paid, list only the open amount, or note the payment in the description.
- Send on a regular schedule. Monthly statements on the same date set expectations and speed up payment.
- Include the age of each balance. Aging turns a list of numbers into a clear priority for the customer's accounts team.
- Keep the tone neutral. A statement is a record, not a demand letter. If an account stays overdue, consider charging a contractual late fee using the late fee calculator.

Frequently asked questions
What is the difference between an invoice and a statement of account?
An invoice bills a customer for a specific sale or job. A statement of account summarizes all invoices, payments and credits over a period and shows the total balance owed.
How often should I send a statement of account?
Most businesses send statements monthly, on the same date each month, to every customer with an open balance.
What is an aging summary on a statement?
It groups the balance by how long it has been outstanding, such as current, 1–30, 31–60, 61–90 and over 90 days, so the customer can see what is overdue.
Can a customer pay from a statement?
Yes, as long as the statement includes your payment instructions. The customer should reference the statement or invoice numbers so you can apply the payment correctly.
