What Is a Statement of Account? When to Send One (+ Free Template)

The document that chases five overdue invoices at once

Say a design client has slipped on invoices #1041, #1048, and #1052 over the past four months. You could send three separate payment reminders and hope their bookkeeper connects the dots. Or you could send a single sheet that lists all three, shows the running total they owe, notes what they've already paid, and lands on one clear number at the bottom: £4,280 outstanding.

That single sheet is a statement of account. It isn't a new bill. It's a summary of the account between you and one customer over a period of time, pulling together invoices, payments, credits, and the resulting balance.

Freelancers and small businesses tend to skip statements entirely, which is a mistake. When a client owes you for multiple jobs, a statement is the fastest way to make the total impossible to ignore, and it saves you from writing five awkward emails.

Statement of account vs invoice, receipt, and reminder

These get muddled constantly, so here's the clean distinction:

• An invoice requests payment for a specific job or order. It creates a new obligation.
• A receipt confirms that a payment has been made. It's proof, not a request.
• A payment reminder nudges the client about one overdue invoice.
• A statement of account summarizes multiple transactions and shows the net balance owed across an account.

The critical point: a statement does not replace an invoice. Your client still pays against the individual invoice numbers. The statement just gives both sides a shared, reconciled view. If you ever send a statement as though it were a bill in its own right, expect confusion, and in some jurisdictions you can't claim tax on a statement the way you can on a proper tax invoice or VAT invoice.

The two types: open-item and balance-forward

Statements come in two formats, and choosing the right one depends on how your client thinks about paying you.

Open-item statement

An open-item statement lists only the invoices that are still unpaid. Each line is a live item waiting to be settled. Once an invoice is paid in full, it drops off the next statement.

This is the format most freelancers and service businesses should use. Clients pay invoice by invoice, so showing them exactly which invoices are open, with dates and amounts, tells them precisely what to action.

Example of an open-item statement:

Balance-forward statement

A balance-forward statement shows an opening balance carried from the previous period, then every transaction during the current period (new invoices, payments received, credit notes), and closes with a new balance. It's the format you see on a credit card statement or a utility bill.

This suits ongoing accounts with lots of activity, where a client is constantly ordering and paying, and neither side wants to track each invoice individually. If you run a retainer arrangement or supply a client weekly, balance-forward can be cleaner.

Example of a balance-forward statement for June:

Notice how a credit note reduces the balance without being a cash payment. Balance-forward statements handle that neatly because they track movement, not just open bills.

If you're unsure which to use, default to open-item. It answers the only question that matters to a slow payer: which invoices do I need to pay, and how much.

What goes on a statement of account

A usable statement includes:

• Your business name, address, and contact details, plus your tax or company number if you have one.
• The client's name and address, exactly as on the invoices.
• A statement date and, for balance-forward, the period covered (e.g. "1–30 June 2026").
• A "statement number" is optional but helps if you send them regularly.
• Line items: date, invoice number, short description, amount, and running balance.
• Payments and credits applied during the period (essential for balance-forward, useful for open-item so the client sees you've recorded their payments).
• The total amount outstanding, prominent and unambiguous.
• Ageing, if you want to apply gentle pressure (more on this below).
• Payment instructions: bank details, accepted payment methods, and a due date or "please settle within 7 days."

Add a short line making clear it's a summary, not a new charge: "This is a statement of your account. Please pay against the individual invoice numbers listed above."

Ageing: the quiet pressure tactic

An ageing statement (sometimes "aged debtors" or "aged receivables") groups the outstanding balance by how overdue each amount is. It's one of the most persuasive things you can put in front of a client, because it shows exactly how long they've been holding your money.

A typical ageing summary sits at the foot of the statement:

Seeing $2,030 sitting in the "61–90 days" column is far harder to rationalize than a single overdue line buried in an email thread. If your invoices carry late fees, the ageing columns also make it obvious which balances have started accruing them.

When to send one

There's no single correct cadence, but these are the moments a statement earns its keep:

1. Monthly, for any client with more than one open invoice. Send it on the same date each month (say, the 1st) so it becomes a predictable prompt for their accounts payable.
2. When invoices are stacking up unpaid. Two or three overdue invoices are the classic trigger. One statement beats three reminders.
3. At the end of a project or quarter. A closing statement confirms everything is settled, or flags what isn't, before you both move on.
4. When a client's bookkeeper asks for one. Larger clients often request a statement to reconcile their own records before a payment run. Sending it proactively can get you into that payment run sooner.
5. Before escalating. A formal statement showing a large aged balance is a reasonable last step before you consider the harder options in what to do when a client won't pay.

For a client who always pays each invoice on time, you don't need statements at all. They're a tool for accounts with activity or friction, not routine paperwork for everyone.

A sample covering email

Attach the statement as a PDF and keep the message short:

Subject: Statement of account — Your Business — as of 15 July

Hi Priya,

Attached is your current statement of account. It summarizes three invoices that are still open, totaling £4,280. Invoice #1041 (£1,200) is now over 90 days past due.

Could you let me know when I can expect payment, or which of these are queued in your next run? Bank details are on the statement, and payment should be made against each invoice number.

Happy to resend any of the original invoices if that helps your records.

Thanks, Daniel

Factual, specific, no apology for asking. Naming the oldest invoice and its age does most of the work.

Building your template

You don't need special software. A statement is a table, and you can build a reusable version in Excel, Word, or Google Docs in about twenty minutes. Structure it like this:

• Header block: your details left, client details right, statement date and period below.
• Body table: Date | Invoice # | Description | Charges | Payments | Balance.
• Totals block: total outstanding, in bold, larger font.
• Ageing table: the five columns shown above.
• Footer: payment instructions and the "this is a summary" note.

In a spreadsheet, make the Balance column a running formula (=previous balance + charges − payments) and let the total pull from it automatically. That way you update one row and the numbers reconcile themselves, which removes the most common statement error: a total that doesn't match the lines above it.

Most invoicing apps generate statements automatically from your unpaid invoices, so if you already use one, check the reports or customer section before building anything by hand.

Common slip-ups

• Balances that don't match the client's records. If they've paid an invoice you haven't marked as received, your statement will overstate the debt and undermine your credibility. Reconcile before sending.
• Treating the statement as an invoice. It carries no new tax point and shouldn't be the document a client pays "against" in the abstract. Point them to the underlying invoice numbers.
• Missing invoice numbers. Without them, the client's bookkeeper can't match your statement to their ledger, and matching is the whole point.
• Sending it and going quiet. A statement opens the conversation. Follow the tactics in how to get invoices paid faster to keep it moving.

Used well, the statement of account turns a scattered pile of overdue invoices into one number the client has to look at, acknowledge, and deal with. That clarity is usually what gets you paid.
