清楚專業、能達到目的的商務信函

Version A: polite but clear

Subject: Invoices HOC-0412 and HOC-0419: payment now 34 days overdue

Dear Ms. [Surname],

Thank you again for featuring our autumn mugs in your window display. We have heard from several of your customers who found us through your shop, and we value the partnership.

I am writing about two invoices that remain open:

Invoice	Date	Amount	Due date
HOC-0412	2 September	$1,240.00	16 September
HOC-0419	9 September	$865.50	23 September
Total		$2,105.50

We have not yet received payment for either of them, and our reminder of 1 October went unanswered. If payment has already been sent, please accept our thanks and let me know the date so we can match it.

Could you please settle the total of $2,105.50 by [date, 7 days from sending]? Bank details are at the bottom of both invoices. If a split payment would be easier, reply to this email with a date for each part and we will gladly agree it.

We would like to plan your winter order together, and we can confirm the new collection as soon as the account is up to date.

Kind regards, [Your name] Hollow Oak Ceramics | [phone]

Version B: firm (changed paragraphs)

Subject: Final reminder: $2,105.50 overdue since September

Despite our reminder of 1 October, invoices HOC-0412 and HOC-0419 remain unpaid, now 34 days past their due dates.

Please pay the full $2,105.50 by [date]. Until the account is settled, we are unable to dispatch new orders, including the winter collection reserved for you.

If we do not receive payment or a reply by that date, we will apply the late fee set out in our terms of trade (section 5) and pass the matter to our collections partner.

Notes for you

• Use Version A first. If there is no reply within 7 days, send Version B.
• Fill in the bracketed fields and check that the invoice amounts match your records.
• Only mention the late fee if it really is in the terms the client signed.
