How to Send an Invoice to a Client

Most late payments are not refusals — they are invoices that reached the wrong inbox, arrived without context, or made paying inconvenient. Sending well is half of getting paid.

Send it to the person who pays, not only the person who hired you

In larger companies the person who briefed you rarely approves payment. Ask early: "Who should invoices be addressed to, and is there an accounts email?" Then send to that address and copy your contact.

Write a short, clear email

  1. 1Use a subject line with the essentials: "Invoice INV-0007 — Acme Ltd — due 30 June".
  2. 2Open with one sentence of context: what the work was and which agreement it relates to.
  3. 3State the amount and due date in the body, not only in the attachment.
  4. 4Attach the PDF and include a link where the invoice can be viewed and paid.
  5. 5Close with a single, friendly line offering to answer questions.

Attachment, link, or both

  • A PDF is what accounting teams file, so always include one
  • A shareable link lets clients view current status and pay without digging through email
  • Together they cover both the bookkeeper and the approver

Follow up on a schedule, not a mood

Decide your rhythm in advance — for example a gentle nudge three days before the due date, one on the due date, then every seven days. A fixed schedule keeps the tone neutral and professional.
