Make a client-ready invoice in the browser
Written by Feroz Sheikh · Founder, Doha, Qatar
Updated 2026-09-06. This is a working note for a live tool, not legal, tax, or professional advice.
An invoice should tell the client who supplied the work, what was supplied, how much is due, when payment is expected, and where payment should be sent. Enter legal names and current contact details rather than leaving sample placeholders in the document.
Check the invoice number, issue date, due date, currency, quantity, rate, discount, and tax percentage in the live preview. The total is calculated from the values you enter; the tool does not know your tax registration status or statutory rate.
The optional logo is read in this browser for the PDF. OpenToolSuite does not create a hosted invoice link, collect payment, post the transaction to an accounting ledger, or add an OpenToolSuite watermark.
For Gulf VAT, India GST, UK VAT, or any other regime, confirm the correct rate, required tax identifiers, place-of-supply wording, and invoice sequence independently. A formatted PDF is not a tax filing.
If a total later needs correction, preserve the original invoice and issue a credit note that references it. Purchase orders, packing slips, receipts, and payment reminders are separate records and should not silently replace invoice history.
Check a simple invoice total
| Item | Calculation | Amount |
|---|---|---|
| Design work | 2 × 150 | 300.00 |
| Illustrative tax | 300 × 10% | 30.00 |
| Total | 300 + 30 | 330.00 |
The 10% rate is invented for this arithmetic example, not a tax recommendation. Enter your verified rate and currency. Review the invoice number, customer details and payment destination in the PDF. A QR code should contain exactly the payment reference or URL you intend; it does not collect or confirm a payment.
