Invoice Template Fields Checklist
Make sure every invoice carries what it needs.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Check my invoice template. Business type and location: [BUSINESS_AND_LOCATION]. Typical customers (consumers, businesses, public bodies): [CUSTOMER_TYPES]. Current template text or field list: [CURRENT_TEMPLATE]. Tax registration status: [TAX_STATUS]. Compare my template against this checklist and mark each item present, missing, or unclear: seller name, address, and contact; customer name and address; unique sequential invoice number; issue date and supply date; description of goods or services with quantities and unit prices; subtotal, tax lines by rate, and total in one currency; payment due date and accepted methods; bank or payment details; late-payment terms; purchase order reference; tax or registration number where required; and a thank-you line. Return a table: Field | Status | Why it matters | Suggested wording. Then write an improved template in plain text with placeholders, and a short list of items whose legal requirements depend on [JURISDICTION], marked [VERIFY with an accountant]. Do not invent tax rates or registration numbers. Add a three-step routine for numbering invoices without gaps and storing copies.
Fill in before use
Optional: type your details and the prompt above updates. Nothing is saved or sent.
Replace each bracketed placeholder with your own details, then paste into Any AI or another assistant.
