Freelancers, contractors, and small shops can turn a short form into a client-ready PDF invoice, with a live preview that redraws on every keystroke and no account to create. Fill in seller and buyer details, then add line items with quantity, unit, net price, and tax rate; net amounts, tax, totals, and the amount in words are calculated automatically. Item discounts take a percentage or fixed amount off any line under a custom label, and tax applies to the discounted figure. Pick a classic layout or a Stripe-style template, and add your logo as a JPEG, PNG, or WebP file. Invoices can be written in 13 languages, including Brazilian Portuguese, with 122 currencies, 18 date formats, and a number format setting that survives a language switch. Tax labels can read VAT, GST, Sales Tax, or anything else, or the tax columns can be dropped entirely. Bank account, SWIFT/BIC, payment method, due date, and notes sit alongside an optional QR code that can carry a payment link, UPI details, or contact information. Long invoices flow onto extra pages automatically. Saved seller and buyer profiles fill in the next invoice for you, and the data stays in the browser. Download the PDF or copy a shareable link that opens the same invoice for your client.
