Formal letters often fail because the purpose is buried, the dates are missing or the tone is either too soft or too sharp. This template solves that with a letterhead, a reference and subject line, a recipient block, a short body and a signed sign-off, so the recipient can act on the first read and your file holds a dated copy.

The sample is an overdue invoice reminder from Pennyroyal Manufacturing to a customer, with three invoices totalling £7,580.00, a payment date and a stated consequence. Replace the letterhead, registration details, recipient, reference, amounts and dates, then delete the guide page before you send the letter.
