Invoice Generator

No. All invoice data is processed entirely in your browser using JavaScript. Your business name, client details, line items, and amounts never leave your device and are not stored on any server. The PDF is generated locally using jsPDF. Your draft is saved temporarily in localStorage so you do not lose work if you refresh, but it is only accessible from the same browser and is never uploaded.

Yes. Click the logo upload area in the invoice form to add your company logo. Supported formats are PNG, JPG, and SVG. The logo is embedded directly in the generated PDF. For best results, use a PNG with transparent background at least 200×200 pixels.

Yes. You can add multiple tax rates (VAT, GST, sales tax) as a percentage of subtotal, as a fixed amount, or as a compound rate applied after other taxes. The invoice automatically calculates subtotal, each tax amount, and grand total, displaying them in a clear breakdown section. You can also add discount lines (percentage or fixed amount).

Yes. After filling in your business details, you can save them as a template using the "Save as Template" button. Your business information (name, address, logo, payment terms) is saved in localStorage and auto-filled for future invoices. Client details can also be saved for frequently billed clients. All templates are stored locally in your browser.

You can enter any invoice number manually. Common formats include sequential numbers (INV-001, INV-002), year-prefixed (2024-001), or date-based (20240115-01). The generator does not auto-increment because it has no server-side state, but it suggests the next number based on your last saved invoice number stored in localStorage.

The generator produces a professional invoice layout that includes the standard fields required in most jurisdictions (invoice number, date, seller/buyer details, itemized charges, tax breakdown, totals). However, legal requirements for invoices vary by country — some jurisdictions require specific fields like VAT registration numbers, payment terms in specific formats, or electronic signature requirements. Verify your local invoicing requirements before using for formal business purposes.

A complete invoice needs: the word 'Invoice' and a unique invoice number; your name/business and contact details; the client's details; the issue date and a payment due date; an itemized list of goods or services with quantities and rates; the subtotal, any tax, and the total due; and clear payment instructions. Many jurisdictions also require a tax/VAT number once you're registered — check your local rules.

Use a sequential, never-reused scheme — INV-0001, INV-0002, or a dated form like 2026-014. Sequential numbers make gaps obvious, simplify bookkeeping and tax filing, and look professional to clients. Avoid restarting the count each month or reusing a number for a revised invoice; instead issue a credit note or a clearly marked revision.
