Statement of Account
A statement of account is a periodic summary a seller sends one customer, listing every invoice, payment, credit, and adjustment over a period, from an opening balance to a closing balance. Many statements add an aging breakdown that splits the balance owed by days past due.
Key Takeaways
A statement of account doesn't demand payment for a sale. It shows both sides the same ledger so they can agree on the balance.
The closing balance equals the opening balance plus invoices, minus payments and credits. The aging buckets must add up to that same number.
Aging buckets run current, 1-30, 31-60, 61-90, and 90+ days past due.
"Account statement" also names a bank's record of deposits and withdrawals, so the seller's document needs the full term.
Customers match the statement against their payables ledger to catch missing invoices, unapplied payments, and duplicates.
What lines does a statement of account carry?
A statement carries an opening balance, one line per invoice, payment, and credit, a running balance, and a closing balance. This worked statement covers September 2026.
Date | Reference | Description | Amount | Running balance |
|---|---|---|---|---|
Sep 1 | Opening balance | 9,200.00 | ||
Sep 3 | INV-1044 | Invoice | 4,500.00 | 13,700.00 |
Sep 8 | PMT-1 | Payment on INV-1033 | -1,000.00 | 12,700.00 |
Sep 11 | PMT-2 | Payment, INV-1044 | -4,500.00 | 8,200.00 |
Sep 12 | INV-1049 | Invoice | 2,250.00 | 10,450.00 |
Sep 19 | CM-0207 | Credit memo on INV-1049 | -600.00 | 9,850.00 |
Sep 24 | INV-1055 | Invoice | 3,100.00 | 12,950.00 |
Sep 30 | Closing balance | 12,950.00 |
The opening balance should match the prior statement's closing balance. Each line points to a document the customer already holds, such as an invoice.
How are the closing balance and aging buckets computed?
The closing balance is the opening balance plus invoices, minus payments and credits, and the aging buckets split it by days past due. For the statement above, 9,200.00 + 9,850.00 - 5,500.00 - 600.00 = 12,950.00.
Aging buckets count days past due. Under net 30 payment terms, the due date is usually the invoice date plus 30 days.
Open invoice | Due date | Days past due at Sep 30 | Open amount | Bucket |
|---|---|---|---|---|
INV-1009 | Jun 19 | 103 | 1,100.00 | 90+ |
INV-1021 | Jul 12 | 80 | 2,400.00 | 61-90 |
INV-1033 | Aug 27 | 34 | 2,800.00 | 31-60 |
INV-1038 | Sep 14 | 16 | 1,900.00 | 1-30 |
INV-1049 | Oct 12 | not due | 1,650.00 | Current |
INV-1055 | Oct 24 | not due | 3,100.00 | Current |
The buckets sum to the closing balance: 4,750.00 current + 1,900.00 + 2,800.00 + 2,400.00 + 1,100.00 = 12,950.00. PMT-2 paid INV-1044 in full, and PMT-1 left 2,800.00 of INV-1033 open.
Which documents get confused with a statement of account?
Several documents get mistaken for a statement of account, and they differ in issuer and scope.
Document | Issued by | Covers | Purpose |
|---|---|---|---|
Invoice | Seller | One sale | Demands payment |
Statement of account | Seller | One customer, one period | Reconciles the balance |
Bank account statement | Bank | One bank account | Records deposits and withdrawals |
Balance confirmation | Auditor, signed by a company officer | One balance at a date | Verifies a receivable independently |
People often shorten statement of account to "account statement", and the same words name a bank record. This page keeps "account statement" for banks. A balance confirmation flows the other way: an auditor mails a letter asking the customer to report its balance straight back to the auditor.
What do teams use a statement of account for?
Teams use a statement for reconciliation, collections follow-up, and month-end records.
Customer reconciliation. The customer's payables team checks each open invoice, each payment, and the closing balance against its own ledger.
Collections. Attaching a statement to a reminder gives the customer one reconciled list to pay from, which pairs with dunning management.
Close. Statements support the seller's own close by confirming customer balances, and payment reconciliation covers matching cash to invoices.

FAQ
Is a statement of account a bill?
No, a statement of account isn't a bill or a legal demand for payment. The invoices it lists carry the payment obligation. The statement summarizes them and shows the total, so a customer can confirm the balance before paying.
Do the aging buckets have to add up to the closing balance?
Yes, the buckets must sum to the closing balance exactly. In the worked statement above, 4,750.00 + 1,900.00 + 2,800.00 + 2,400.00 + 1,100.00 equals the 12,950.00 closing balance. A mismatch means the statement has an error to find before it goes out.
Does a statement of account include paid invoices?
It depends on the statement type: a balance forward statement does, and an open item statement doesn't. In common accounting software terms, a balance forward statement lists the invoices, payments, and current balance for a date range, so an invoice paid inside the period shows up with its payment line. An open item statement lists only unpaid invoices, so INV-1044 above wouldn't appear on one.
