Customer statement of account: what to include and when to send it

A customer statement of account is a summary of every invoice, payment, credit note and adjustment on a customer's account over a period, ending with the balance they owe you. Unlike an invoice, it doesn't ask for payment for a new supply; it shows the running position so the customer can check their records against yours and pay what is outstanding.

Most South African businesses send statements monthly, usually in the first few days after month-end. Done well, a statement quietly does a lot of collections work for you.

Statement vs invoice: what's the difference?

It's common for customers (and staff) to confuse the two, so it helps to be clear:

Because a statement isn't a tax invoice, never rely on it for VAT. Your customer claims input tax from the tax invoice itself. If you're unsure what a valid tax invoice needs, see our guide to VAT invoice requirements in South Africa.

What to include on a customer statement of account

A useful statement answers three questions at a glance: what did I owe at the start, what happened during the period, and what do I owe now?

1. Your business details: registered name, trading name, address, VAT number if registered, and contact details for accounts queries.
2. Customer details: name, account number and billing address.
3. Statement date and period, for example "1 to 31 August 2026".
4. Opening balance brought forward from the previous statement.
5. Transactions in date order: invoices (with numbers), payments received, credit notes, refunds, and any journal adjustments, each with a reference.
6. Closing balance, clearly labelled as the amount due.
7. Ageing summary: current, 30, 60, 90 and 120+ days. This shows the customer which invoices are overdue.
8. How to pay: bank details for EFT, the reference to use, and a pay-online link if you offer one.
9. A short note on queries, such as "Please let us know of any differences within 7 days."

A worked example

Here is an illustrative statement for a customer on 30-day terms:

Ageing: Current R4,370.00 · 30 days R0.00 · 60 days R0.00 · 90+ days R0.00.

The customer can see immediately that last month's balance was cleared, what was billed this month, and that a credit was applied. There's nothing to argue about, which is the point.

When to send statements

• Monthly, soon after month-end. This is the norm for B2B accounts and it lines up with how your customers' finance teams reconcile their creditors.
• On request. Auditors and customers' creditors clerks often ask for a statement to reconcile their books. Make it easy to produce one for any date range.
• Before escalating a debt. A statement showing the exact overdue invoices is a sensible step before a final demand.
• When an account is closed, to confirm a nil balance or show what remains.

For customers who only buy once, a statement adds little. Send the invoice and a receipt instead.

Open-item vs balance-forward statements

There are two common formats:

• Balance-forward statements (like the example above) show an opening balance, the period's movements and a closing balance. They're easy to read and suit most small businesses.
• Open-item statements list only the invoices that are still unpaid, however old, with any part-payments against each one. They're better when customers pay invoice by invoice and need to know exactly which ones are outstanding.

Pick one format and stick to it, because switching confuses customers who reconcile against you every month.

Common statement problems (and how to avoid them)

Unallocated payments. A customer pays R4,600.00 but the payment isn't matched to the invoices, so the statement shows both the invoices and a floating credit. Allocate payments to specific invoices before you send statements.

Missing credit notes. If you agreed a discount on the phone but never issued the credit note, the statement will show the full amount and the customer will query it. Issue the credit note first. Our post on credit notes vs refunds covers when to use each.

Wrong cut-off. Payments that cleared on the last day of the month but were only captured later make the statement look wrong. Reconcile your bank statement before generating customer statements.

No payment path. A statement that says "amount due" without bank details, a reference or a link just creates another email. Always include a way to pay.

Using statements alongside other collection tools

A statement works best as one part of a routine:

1. Invoice promptly with clear payment terms.
2. Send friendly reminders around the due date.
3. Send the monthly statement with ageing.
4. Review your aged receivables report and follow up the 60- and 90-day balances personally.

Statements keep the customer's records aligned with yours; reminders and phone calls deal with specific overdue invoices.

How CentraPoint helps

CentraPoint produces branded PDF statements alongside invoices, receipts and refund notes, so every document carries your logo and details. Because invoices, gateway payments, recorded EFT and cash payments, and credit notes all live in one ledger per customer, the statement reflects what actually happened. Customers can also sign in to the customer portal with a one-time email code to view and pay invoices and download receipts, which cuts down on "please resend my statement" emails. See how invoicing works in the docs.

Frequently asked questions

Is a statement of account a tax invoice?

No. A statement summarises the account, but it doesn't meet the requirements of a tax invoice under the VAT Act. Your customer needs the original tax invoice to claim input tax.

How often should I send customer statements?

Monthly is standard for customers on credit terms, usually within the first week after month-end. You should also be able to produce one on request for any period.

What is an opening balance on a statement?

It's the amount the customer owed at the start of the statement period, carried forward from the previous statement's closing balance.

What should a customer do if the statement is wrong?

They should contact your accounts team with the specific transaction they dispute, ideally with proof of payment or a reference. Resolve it with a credit note or payment allocation rather than editing the statement.
