Invoice Generator

What Invoice Generator helps you do

Create a professional invoice online without opening a spreadsheet, signing up for accounting software, or sending sensitive client details to Haivix. The live invoice maker combines business and client information, itemized charges, dates, currency, tax, discount, notes, and payment terms in a polished PDF-ready layout. It is built for a single invoice or a repeatable freelance workflow, not for ledger accounting.

Invoice details and PDF creation stay in your browser. The draft is saved in local storage on the current device and can be cleared at any time; Haivix does not upload the invoice.

How it works

The page keeps the invoice fields in a form, recalculates the line totals, subtotal, discount, tax, shipping and amount due as you type, and renders the result into a print-ready layout. The draft is written to local storage on the current device. Download PDF captures the layout for sending; Print uses the browser's own PDF engine and can preserve selectable text.

How to use Invoice Generator

1. Enter your business and client details, then add the invoice number, issue date, due date, and currency.
2. Add each product or service with its quantity and rate, then apply any discount, tax, shipping, notes, and payment terms.
3. Review the live invoice preview and check the arithmetic on the amount due.
4. Download the finished PDF or print a copy for your records.

Example

A designer bills three line items: a logo at a fixed fee, a website at an hourly rate, and a small hosting reimbursement. A 10% discount is applied before VAT, and the payment terms give 14 days. The live total is checked against the quote, the PDF is downloaded, and a copy is kept with the project files.

What you can do with Invoice Generator

• Build an itemized invoice with automatic subtotal, discount, tax, shipping, and amount-due calculations.
• Add your business logo and choose an accent color for a branded invoice.
• Choose from common global currencies, including USD, EUR, GBP, PKR, INR, AED, and SAR.
• Label tax as VAT, GST, sales tax, or another local term.
• Preview every change live, download a PDF, or print from the browser.
• Keep the working draft in local browser storage and clear it whenever you want.
• Reorder or remove line items before the final export.

Example: invoice a client for freelance work

Add your business and client details, choose the correct currency, and confirm the invoice number, issue date, and due date. Enter each service as a separate line item so the client can understand the quantity, rate, and amount.

Apply any agreed discount before tax, add VAT, GST, or sales tax where required, and write clear payment instructions. Check the live preview, confirm the amount due, and download the professional PDF to email or message to your client.

Save a copy of the PDF and the source details with your records. If the client questions a line, you can compare the invoice with the original quote instead of reconstructing the numbers later.

What to know before you start

• The draft is saved on the current device only; it is not an online invoice-tracking or payment-reminder system.
• Your uploaded logo is used for the current session and is not included in the locally saved draft.
• Tax, invoice-numbering, registration, and recordkeeping rules vary by country and business type.
• Review names, dates, currency, tax treatment, bank details, and the final total before sending the PDF.
• The template is a general business layout, not a certified tax or e-invoicing format.

Common mistakes

• Applying tax before the discount when the agreed order is discount first.
• Using a currency symbol that does not match the amount or the bank details.
• Forgetting the invoice number, issue date or due date.
• Sending an invoice with an old client address or contact name.
• Assuming the local draft is a backup; it lives only in this browser profile.
• Using a photo or logo file that is not licensed for the invoice.

Troubleshooting

If a total looks wrong, check the discount order, the tax rate and whether shipping is taxable in your case. Recalculate the line items by hand as a cross-check.

If the downloaded PDF looks different from the preview, check the browser's print scale and margins. The preview is A4-oriented; the print dialog can override it.

If the draft disappears, the browser may have cleared local storage or you may be in a private window. Keep the PDF and your own copy of the figures.

If the logo is missing after reopening, upload it again; logos are session-only and are not written into the saved draft.

If the client's accounting system rejects the file, check whether it requires a specific e-invoice format or a purchase-order reference.
