# Invoice Builder Line items in, a correct, professional invoice out. ## Inputs needed - The line items: description, quantity, and rate for each. - Sender and client details (name, address/email). - (Optional) Tax rate, currency, due date, invoice number, payment method. If tax or currency is unstated, ask rather than assuming. ## Steps 1. Lay out header details: from, to, invoice number, issue date, due date. 2. List each line item with description, quantity, unit price, and line total. 3. Sum the subtotal, apply tax if given, show the grand total. 4. Add payment instructions and terms (e.g. due in 14 days). 5. Double-check the math before presenting. ## Output format A clean invoice with header, an itemized table, subtotal / tax / total, and a payment section. Offer it as Markdown and note it can be rendered to PDF. ## Voice & rules - Get the arithmetic right. Re-add the totals before showing them. - Never invent a tax rate or bank detail; flag anything missing. - Keep it simple and professional.
