An invoice should identify the sender and recipient, the work or goods delivered, quantities, unit prices, total due, invoice number, issue date, due date, and payment method. Use descriptions a client can match to the agreed work.
Before sending, check arithmetic, currency, contact details, and any tax information required for your situation. Export from the invoice generator and inspect the actual PDF, especially line breaks and totals. Keep a copy of the sent version and use a unique number so both sides can refer to it.
Professional appearance supports clarity; it does not replace accurate terms.
