The customer statement of account: what to send, when, and how to word it

What is a customer statement of account?

A customer statement of account is a dated list of everything that changed what one customer owes you over a period, ending in the amount due today. It starts from the opening balance, adds each invoice, subtracts each payment and credit note, and shows the balance after every line.

It is not an invoice and it does not ask for tax. It is a copy of the customer's account in your books, so their accounts person can tick it against their own ledger and pay the right amount.

What should a good statement of account contain?

A good statement lets the customer check every rupee without calling you. It needs these parts, in this order:

• Your business name and GSTIN, the customer's name and GSTIN, and the date range covered
• The opening balance on the first day of the range
• One dated row per document: invoice, payment received, credit note, debit note
• The document number on every row, so the customer can find it in their own books
• A debit column, a credit column and a running balance after each row
• The closing balance on the last day, stated as the amount due
• An ageing strip at the foot showing how much of the balance is current and how much is overdue, by bucket
• How to pay: bank details or the UPI ID, and who to call with a question

What does a sample statement of account look like?

Here is September for Sri Annamalai Furniture Mart, a customer of Lakshmi Steel Furnitures, the fictional Coimbatore business used across this site. The customer has 30 credit days.

The ageing strip under it explains the balance. Payments were applied to the oldest invoices first and the credit note to the invoice it corrects, so ₹15,000 is left on an August invoice that fell due on 17 September. Everything else is still within 30 days.

That one line tells the customer what to pay now (₹15,000) and what is coming (₹1,35,700), which is far easier to act on than a single large number.

Why does a statement work better than a reminder?

A statement removes the reasons not to pay. A bare reminder says "please pay ₹1,50,700", and the customer's accountant has to rebuild the figure before releasing anything. If they cannot, the payment waits.

• It answers the question before it is asked. Every number has a date and a document behind it.
• It surfaces disputes early. If a credit note is missing on their side, you hear about it this month, not at year end.
• It reads as routine, not as chasing. Sent to every customer on the same day, it does not single anyone out.
• It becomes their payment list. Many accounts teams simply pay the overdue rows on the statement.

How often should you send a statement of account?

Send a statement to every customer with a balance on the first working day of each month, and every week to customers with overdue amounts.

1. 1

   1st of the month: everyone with a balance

   Date range: the previous month. This is the routine statement. It also lets customers book your invoices before they close their own month.

2. 2

   Every Monday: customers with anything overdue

   Date range: from the oldest unpaid invoice to today. Pull the list from the ageing report and send only to rows with an overdue column above zero.

3. 3

   Before a large new order: the buyer's current position

   If a customer is near their credit limit, send the statement with the quote. It sets the conversation about clearing old dues first.

4. 4

   Quarter end and 31 March: balance confirmation

   Ask the customer to confirm the closing balance in writing. Your auditor will want it, and so will theirs.

How do you send a statement of account?

Send it the way the customer's accounts person actually reads things, and keep the message short. There are three common ways:

• PDF by email. Best for companies with an accounts department. Attach the PDF and put the closing balance and overdue amount in the subject line.
• Printed with the next delivery. Works well for shops and contractors who receive goods often. The driver hands it over with the delivery challan.
• Pasted text on a messaging app. Best for owner-run customers who answer their phone, not their email. Paste a short summary and attach the PDF.

How should you word a statement for each situation?

The wording should match how late the money is: neutral for routine, specific for overdue, and firm with a date for final. Three templates you can adapt:

Routine monthly statement

Overdue reminder with the statement

Final notice before stopping supply

Keep the final notice factual. State the amount, the due date, the date you will act and what you will do. Do not threaten anything you will not carry out.

What do you do when the customer says the balance is wrong?

Ask for their ledger for the same date range and compare it line by line with your statement. Almost every difference comes from one of a short list of causes.

Once the difference is found, send a corrected statement and ask for written confirmation of the agreed balance. That one email saves a long argument later.

How does SimpleERP produce a statement of account?

In SimpleERP the statement is built from posted documents, so it always agrees with the ledger and the ageing report. Nobody types it.

• Pick a party and a date range. The statement shows the opening balance, a dated row for every invoice, payment and credit note with its document number, a running balance and the closing balance.
• An ageing footer under the closing balance shows the same buckets as the receivables ageing report.
• Print it or save it as a PDF to email.
• Copy share text puts a short summary on your clipboard, ready to paste into any messaging app from your own phone. A reminder text can be copied the same way.
• Payments can be split across many invoices, and unallocated advances sit on the party, so the per-invoice ageing stays right.
