One sent a week later reads as a request. Attach it to the delivery email.\n\n## Seven lines, no more\n\n1. Your name or business name, and how to reach you.\n2. The client and the person who approves payment.\n3. An invoice number. Start at 1001; nobody needs to know it is your first.\n4. The date sent and the date due.\n5. One line per piece of work, each with its price.\n6. The total, and any tax on it.\n7. How to pay: one method, written out in full.\n\n## The line that gets it paid\n\n> Due 14 days from today, on 26 May.\n\nName the date, not the terms. \"Net 14\" asks the client to count.
