Create an Invoice for a Sale
Create an invoice from your business details, customer details and line items. Add a due date, discount, shipping charge and tax rate where needed. Preview the totals, then print or save a PDF through your browser. This invoice generator does not send invoices or collect payments.
Create an Invoice Your Customer Can Check
Enter your business name and address, the customer details and an invoice number from your own sequence. Add the issue date and an optional due date. Include an order reference if it helps the customer match the invoice to a purchase.
Add each item with its quantity and unit price. Check discounts, shipping and tax before you update the preview. Enter any amount already paid to show the balance due. Review the final document, then open the print view or download the HTML file.
Understand How the Totals Work
Each line amount is quantity times unit price, rounded to the currency precision used by the tool. An order discount reduces the goods subtotal. Shipping is added separately. Tax applies to discounted goods, plus shipping only if you select that option.
The form uses one tax rate. It does not support mixed tax categories, reverse charges or all local invoice rules. Tax IDs are optional fields in the form, not a statement that they are optional under your law. Confirm required details before you issue the invoice.
Keep the Invoice Linked to the Payment
An invoice requests payment. It is not proof that money arrived. Match any amount paid to your own payment records. Use the receipt generator after you receive funds, and retain the invoice reference on both documents.
The print view contains your entered details and line items. The browser controls PDF saving and page size. Check long item descriptions and page breaks before you share the file.
