Invoice approval request email prompt: free ChatGPT template

SOPs and operationsOperationsFinanceWorks in ChatGPT, Claude, Gemini and Copilot

Updated · By Robert Breen

Use this when an invoice is above your approval limit and the owner or a partner has to say yes. It turns the extracted details into a short email that states what the invoice is for, the amount, the due date and what you already checked, so the approver does not have to open the PDF to decide.

It writes the request, it does not approve or pay anything. Pair it with an approval step in your process, and keep a record of the answer. It works as the manual version of the approval email in the lesson.

The prompt

Copy it into ChatGPT (or Claude, Gemini or Copilot) and replace every [BLANK] with your own details. It uses the four parts from Prompt Writing 101: Role, Context, Task and Format.

Role: You are an accounts payable coordinator at [COMPANY], writing an approval request to [APPROVER] for an invoice above our approval limit.
Context: The invoice details are: [DETAILS]. The checks already done are: [CHECKS]. Our approval limit is [LIMIT]. Use only these facts. Do not guess a purpose, a budget code or a due date that is not listed, and write "to confirm" for anything missing.
Task: Write a short email that asks the approver to approve or decline. Put the vendor, invoice number, amount, due date and purpose in the first three lines, say what was checked, name any concern in one sentence, and end with a clear request to reply Approve or Decline by [DEADLINE].
Format: A subject line and an email under [WORD LIMIT] words, plain and polite, with the key facts as a short list at the top.

Fill in the blanks

[COMPANY]
Your company or firm name.
[APPROVER]
Who must approve, such as the owner.
[DETAILS]
Vendor, invoice number, amount, dates and what it is for.
[CHECKS]
What you already checked, such as a match with the purchase order.
[LIMIT]
The amount above which approval is needed.
[DEADLINE]
When you need the answer, such as Friday noon.
[WORD LIMIT]
120 keeps it quick to read.

Example, filled in

A made-up example from the free lesson Invoices from Your Inbox to Google Sheets, with Approval. Cobalt Street Architects is the made-up firm in the invoices-from-your-inbox lesson, where invoices over $1,000 wait for the owner's approval. The invoice details here are an illustration, not the lesson's invoice.

Role: You are an accounts payable coordinator at Cobalt Street Architects, writing an approval request to the owner for an invoice above our approval limit.
Context: The invoice details are: vendor Tidewater Office Supply, invoice number 4471, total $1,860.00, due in 30 days, for printer paper, toner and two drafting tables. The checks already done are: the vendor is on our approved list and the quantities match the order email. Our approval limit is $1,000. Use only these facts. Do not guess a purpose, a budget code or a due date that is not listed, and write "to confirm" for anything missing.
Task: Write a short email that asks the approver to approve or decline. Put the vendor, invoice number, amount, due date and purpose in the first three lines, say what was checked, name any concern in one sentence, and end with a clear request to reply Approve or Decline by Friday noon.
Format: A subject line and an email under 120 words, plain and polite, with the key facts as a short list at the top.

What a good answer looks like

  • The approver can decide from the first three lines without opening the PDF.
  • What was checked is stated, and anything missing says "to confirm".
  • The ask is a single reply, Approve or Decline, with a deadline.

How to check it before you use it

An AI draft can sound right and still say something you never told it. Use the habit from the Reply Faster lesson: check every promise, name, date and number against what you gave it before anything goes out.

  • Compare every figure with the invoice itself before you send.
  • Confirm the vendor and bank details through a known contact if anything looks unusual.
  • Do not pay until a person has replied. The email is a request, not an approval.
  • Save the reply with the invoice so there is a record.

Why this prompt works

Putting the decision facts first respects the approver's time, and the Approve or Decline format makes the answer easy to record.
