The best invoice email is short, specific and easy to act on. The customer should immediately understand what the invoice covers, how much is due, the deadline and how to pay.

What to include

Every invoice email should contain:

  • a clear subject line
  • the customer's name
  • invoice number
  • short description of the work or order
  • amount due and currency
  • due date
  • payment method or link
  • attached invoice or secure viewing link
  • your contact details

Subject lines that work

  • Invoice INV-2026-0148 from Brightline Studio
  • Invoice for May consulting services
  • Deposit invoice for the website project
  • Invoice and delivery note for LPO reference
  • Reminder: invoice due tomorrow
  • Payment follow-up for overdue invoice

Avoid vague subjects such as “Document”, “See attached” or “Urgent”.

Before you press send

Check the recipient, invoice number, amount, currency, due date, attachment and payment details. Sending a corrected invoice immediately after the first one can cause delays in an accounts department.

You can create and send an invoice online or begin with the free invoice template. Our invoice-number guide will help you keep references consistent.

Frequently asked questions

Should I attach a PDF or send a link?

Either can work. A PDF is easy for an accounts team to store, while a secure link may provide a current payment status. Avoid sending sensitive customer information through an untrusted link.

Can I send the same message through WhatsApp?

Yes, but shorten it for chat and attach the professional document. Read our WhatsApp invoice guide.

When should I follow up?

A reminder shortly before the due date is reasonable. After the deadline, follow up promptly and keep a record of every message.
